2.2 Spring配置

配置文件分为两部分，一部分Mybatis的配置，一部分是Oauth2的配置。

2.2.1 Mybatis配置

spring-mybatis.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

                    http://www.springframework.org/schema/aop/spring-aop.xsd
                    http://www.springframework.org/schema/context      
                    http://www.springframework.org/schema/context/spring-context.xsd">

    <bean id="annotationPropertyConfigurerMybatis"

    </bean>

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager" />

    <!-- jdbcTemplate -->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
        
        <!-- 如果用xml方式，而不是用注解去写sql，这地方要注明xml文件的路径 -->
<!--        <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml" /> -->
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.pomit.springwork.mybatis.mapper" />
    </bean>
</beans>

这里重点不是mybatis的配置，就不细说了。

配置文件：

db.url=jdbc:mysql://127.0.0.1:3306/cff?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
db.username=cff
db.password=123456
#db.dirverClass=com.mysql.cj.jdbc.Driver
#6.0以上用com.mysql.cj.jdbc.Driver.
db.dirverClass=com.mysql.jdbc.Driver

2.2.2 Oauth2配置

spring-oauth.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

                    http://www.springframework.org/schema/aop 
                    http://www.springframework.org/schema/aop/spring-aop.xsd
                    http://www.springframework.org/schema/context      
                    http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config />
    <context:component-scan base-package="cn.pomit.springwork">

                <entry key="MwonYjDKBuPtLLlK" value-ref="clientDetails" />
                <entry key="VJUpAlhdWPbvkpPy" value-ref="clientDetails1" />
            </map>
        </property>

    </bean>

    <bean id="clientDetails"

        <property name="clientId" value="MwonYjDKBuPtLLlK" />
        <property name="clientSecret" value="secret" />
        <property name="accessTokenValiditySeconds" value="3600" />
        <property name="refreshTokenValiditySeconds" value="3600" />
        <property name="scope">
            <set>
                <value>read</value>

        </property>
        <property name="authorizedGrantTypes">

                <value>refresh_token</value>

            </set>
        </property>
        <property name="authorities">
            <list>
                <bean
                    class="org.springframework.security.core.authority.SimpleGrantedAuthority">
                    <constructor-arg type="java.lang.String" value="ROLE_CLIENT"></constructor-arg>
                </bean>
                <bean
                    class="org.springframework.security.core.authority.SimpleGrantedAuthority">
                    <constructor-arg type="java.lang.String" value="ROLE_TRUSTED_CLIENT"></constructor-arg>
                </bean>
            </list>
        </property>
    </bean>
    <bean id="clientDetails1"
        class="org.springframework.security.oauth2.provider.client.BaseClientDetails">
        <property name="clientId" value="VJUpAlhdWPbvkpPy" />
        <property name="clientSecret" value="secret" />

        <property name="refreshTokenValiditySeconds" value="3600" />
        <property name="scope">
            <set>
                <value>read</value>
                <value>write</value>
                <value>trust</value>
            </set>
        </property>
        <property name="authorizedGrantTypes">
            <set>
                <value>password</value>
                <value>authorization_code</value>
                <value>refresh_token</value>
                <value>implicit</value>
            </set>
        </property>
        <property name="authorities">
            <list>
                <bean
                    class="org.springframework.security.core.authority.SimpleGrantedAuthority">
                    <constructor-arg type="java.lang.String" value="ROLE_CLIENT"></constructor-arg>
                </bean>
                <bean
                    class="org.springframework.security.core.authority.SimpleGrantedAuthority">
                    <constructor-arg type="java.lang.String" value="ROLE_TRUSTED_CLIENT"></constructor-arg>
                </bean>
            </list>
        </property>
    </bean>
</beans>

这里：

tokenStore，存储token使用的bean。
authorizationCodeServices，可以不必自己定义，这里是为了自定义token的长度。
myClientDetailsService，定义了两个client。
clientDetails，client的配置，分别包含clientId、密钥、token时长、刷新token时长、授权类型。

三、配置资源服务器

资源服务器需要使用@EnableResourceServer开启，是标明哪些资源是受Ouath2保护的。下面的代码标明/api是受保护的，而且资源id是my_rest_api。

ResourceServerConfiguration:

package cn.pomit.springwork.security.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler;
import org.springframework.security.oauth2.provider.token.TokenStore;

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    private static final String RESOURCE_ID = "my_rest_api";
    @Autowired
    private TokenStore tokenStore;

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.tokenStore(tokenStore).resourceId(RESOURCE_ID).stateless(false);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.anonymous().disable().requestMatchers().antMatchers("/api/**").and().authorizeRequests()
        .antMatchers("/api/**").authenticated().and().exceptionHandling()
        .accessDeniedHandler(new OAuth2AccessDeniedHandler());
    }

}

四、配置授权服务器

授权服务器需要使用@EnableAuthorizationServer注解开启，主要负责client的认证，token的生成的。AuthorizationServerConfiguration需要依赖SpringSecurity的配置，因此下面还是要说SpringSecurity的配置。

AuthorizationServerConfiguration:

package cn.pomit.springwork.security.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.ClientDetailsService;
import org.springframework.security.oauth2.provider.approval.ApprovalStore;
import org.springframework.security.oauth2.provider.approval.TokenApprovalStore;
import org.springframework.security.oauth2.provider.approval.TokenStoreUserApprovalHandler;
import org.springframework.security.oauth2.provider.code.AuthorizationCodeServices;
import org.springframework.security.oauth2.provider.request.DefaultOAuth2RequestFactory;
import org.springframework.security.oauth2.provider.token.TokenStore;

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    private static String REALM = "MY_OAUTH_REALM";

    @Autowired
    private TokenStore tokenStore;

    @Autowired
    @Qualifier("myClientDetailsService")
    private ClientDetailsService clientDetailsService;

    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;

    @Autowired
    @Qualifier("authorizationCodeServices")
    private AuthorizationCodeServices authorizationCodeServices;

    @Bean
    public PasswordEncoder noOpPasswordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }
    
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(clientDetailsService);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.tokenStore(tokenStore).userApprovalHandler(userApprovalHandler(tokenStore))
                .authenticationManager(authenticationManager);
        endpoints.authorizationCodeServices(authorizationCodeServices);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.allowFormAuthenticationForClients();
        oauthServer.realm(REALM + "/client");
    }
    
    @Bean
    @Autowired
    public TokenStoreUserApprovalHandler userApprovalHandler(TokenStore tokenStore) {
        TokenStoreUserApprovalHandler handler = new TokenStoreUserApprovalHandler();
        handler.setTokenStore(tokenStore);
        handler.setRequestFactory(new DefaultOAuth2RequestFactory(clientDetailsService));
        handler.setClientDetailsService(clientDetailsService);
        return handler;
    }

    @Bean
    @Autowired
    public ApprovalStore approvalStore(TokenStore tokenStore) throws Exception {
        TokenApprovalStore store = new TokenApprovalStore();
        store.setTokenStore(tokenStore);
        return store;
    }
}

这里的

clientDetailsService是配置文件中配置的客户端详情；
tokenStore是token存储bean；
authenticationManager安全管理器，使用Spring定义的即可，但要声明为bean。
authorizationCodeServices是配置文件中我们自定义的token生成bean。
PasswordEncoder密码处理工具类，必须指定的一个bean，可以使用NoOpPasswordEncoder来表明并未对密码做任何处理，实际上你可以实现PasswordEncoder来写自己的密码处理方案。
UserApprovalHandler 需要定义为bean的Oauth2授权通过处理器。

五、SpringSecurity配置

5.1 SpringSecurity常规配置

SpringSecurity的配置在客户端和认证授权服务器中是必须的，这里是单机，它更是必须的。

OAuth2SecurityConfiguration:

package cn.pomit.springwork.security.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;

import cn.pomit.springwork.security.ajax.AjaxAuthFailHandler;
import cn.pomit.springwork.security.ajax.AjaxAuthSuccessHandler;
import cn.pomit.springwork.security.ajax.AjaxLogoutSuccessHandler;
import cn.pomit.springwork.security.ajax.UnauthorizedEntryPoint;
import cn.pomit.springwork.security.service.OauthAuthenticationProvider;

@Configuration
@EnableWebSecurity
public class OAuth2SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private OauthAuthenticationProvider oauthAuthenticationProvider;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(oauthAuthenticationProvider);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        SimpleUrlAuthenticationFailureHandler hander = new SimpleUrlAuthenticationFailureHandler();
        hander.setUseForward(true);
        hander.setDefaultFailureUrl("/authLogin.html");

        http.exceptionHandling().authenticationEntryPoint(new UnauthorizedEntryPoint()).and().csrf().disable()
                .authorizeRequests()
                .antMatchers("/login").permitAll()
                .antMatchers("/authLogin.html").permitAll()
                .antMatchers("/oauth/**").permitAll()
                .anyRequest().authenticated()
                .and().formLogin()
                .loginPage("/authLogin.html")
                .usernameParameter("userName")
                .passwordParameter("userPwd")
                .loginProcessingUrl("/login")
                .successHandler(new AjaxAuthSuccessHandler()).failureHandler(new AjaxAuthFailHandler())
                .and().logout().logoutUrl("/logout").logoutSuccessHandler(new AjaxLogoutSuccessHandler());
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

这里，

OauthAuthenticationProvider 是用户名密码认证处理器。下面会说。
authenticationManager安全管理器，使用Spring定义的即可，但要声明为bean。
configure方法是SpringSecurity配置的常规写法。
UnauthorizedEntryPoint：未授权的统一处理方式。
successHandler、failureHandler、logoutSuccessHandler顾名思义，就是响应处理逻辑，如果不打算单独处理，只做跳转，有响应的successForwardUrl、failureForwardUrl、logoutSuccessUrl等。

5.2 配置Oauth2全局方法拦截

MethodSecurityConfig：

package cn.pomit.springwork.security.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.access.expression.method.MethodSecurityExpressionHandler;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration;
import org.springframework.security.oauth2.provider.expression.OAuth2MethodSecurityExpressionHandler;

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {
    @Autowired
    private OAuth2SecurityConfiguration securityConfig;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }
}

5.3 SpringSecurity用户名密码验证器

OauthAuthenticationProvider 实现了AuthenticationProvider 接口的authenticate方法，提供用户名密码的校验，校验成功后，生成UsernamePasswordAuthenticationToken。

这里面用到的OauthUserDetailsService，需要自己实现从数据库中获取。

OauthAuthenticationProvider :

package cn.pomit.springwork.security.service;

import java.util.Collection;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.stereotype.Component;

import cn.pomit.springwork.security.detail.OauthUserDetails;

@Component
public class OauthAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private OauthUserDetailsService oauthUserDetailsService;

    /**
     * 自定义验证方式
     */
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {

        // 用户名密码校验
        OauthUserDetails oauthUserDetails = (OauthUserDetails) oauthUserDetailsService
                .loadUserByUsername(authentication.getName());
        System.out.println(authentication.getName() + "+++++++++++++++++" + authentication.getCredentials());
        if (!oauthUserDetails.getUserName().equals(authentication.getName())
                || !oauthUserDetails.getPassword().equals(authentication.getCredentials())) {
            throw new BadCredentialsException("用户名或密码错误。");
        }
        Collection<? extends GrantedAuthority> authorities = oauthUserDetails.getAuthorities();
        return new UsernamePasswordAuthenticationToken(oauthUserDetails.getUsername(), oauthUserDetails.getPassword(),
                authorities);
    }

    @Override
    public boolean supports(Class<?> arg0) {
        return true;
    }
}

5.4 用户验证信息获取

OauthUserDetailsService：

package cn.pomit.springwork.security.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import cn.pomit.springwork.mybatis.domain.UserInfo;
import cn.pomit.springwork.mybatis.service.UserInfoService;
import cn.pomit.springwork.security.detail.OauthUserDetails;

@Service("oauthUserDetailsService")
public class OauthUserDetailsService implements UserDetailsService {
    @Autowired
    private UserInfoService appUserService;

    @Override
    public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
        UserInfo user;
        try {
            user = appUserService.getUserInfoByUserName(userName);
        } catch (Exception e) {
            throw new UsernameNotFoundException("user select fail");
        }
        if (user == null) {
            throw new UsernameNotFoundException("no user found");
        } else {
            try {
                return new OauthUserDetails(user);
            } catch (Exception e) {
                throw new UsernameNotFoundException("user role select fail");
            }
        }
    }

}

OauthUserDetails：

package cn.pomit.springwork.security.detail;

import java.util.Collection;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.UserDetails;

import cn.pomit.springwork.mybatis.domain.UserInfo;

public class OauthUserDetails extends UserInfo implements UserDetails {

    public OauthUserDetails(UserInfo appUser) {
        super(appUser);
    }

    /**
     * 
     */
    private static final long serialVersionUID = 6272869114201567325L;

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return AuthorityUtils.createAuthorityList("USER");
    }

    @Override
    public String getUsername() {
        return super.getUserName();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }

    @Override
    public String getPassword() {
        return super.getPasswd();
    }

}

六、自定义的Token的Code生成逻辑

这个就是定义在配置文件中的authorizationCodeServices。

InMemoryAuthorizationCodeServices:

package cn.pomit.springwork.security.service;

import java.util.concurrent.ConcurrentHashMap;

import org.springframework.security.oauth2.common.util.RandomValueStringGenerator;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.code.RandomValueAuthorizationCodeServices;

public class InMemoryAuthorizationCodeServices extends RandomValueAuthorizationCodeServices {
    protected final ConcurrentHashMap<String, OAuth2Authentication> authorizationCodeStore = new ConcurrentHashMap<String, OAuth2Authentication>();
    private RandomValueStringGenerator generator = new RandomValueStringGenerator(16);

    @Override
    protected void store(String code, OAuth2Authentication authentication) {
        this.authorizationCodeStore.put(code, authentication);
    }

    @Override
    public OAuth2Authentication remove(String code) {
        OAuth2Authentication auth = this.authorizationCodeStore.remove(code);
        return auth;
    }

    @Override
    public String createAuthorizationCode(OAuth2Authentication authentication) {
        String code = generator.generate();
        store(code, authentication);
        return code;
    }
}

七、测试Oauth2

7.1 Web测试接口

OauthRest ：


package cn.pomit.springwork.security.web;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import cn.pomit.springwork.security.ajax.ResultModel;

@RestController
@RequestMapping("/")
public class OauthRest {

    @RequestMapping(value = "/api/test", method = { RequestMethod.GET })
    public ResultModel api() {
        return ResultModel.ok("测试api成功");
    }

    @RequestMapping(value = "/user/test", method = { RequestMethod.GET })
    public ResultModel user() {
        return ResultModel.ok("测试user成功");
    }
}

7.2 测试过程

首先访问http://127.0.0.1:8080/api/test。提示

<oauth>
<error_description>
An Authentication object was not found in the SecurityContext
</error_description>
<error>unauthorized</error>
</oauth>

这标明，oauth2控制了资源，需要access_token。

请求授权接口oauth/authorize：http://localhost:8080/oauth/authorize?response_type=code&client_id=MwonYjDKBuPtLLlK&redirect_uri=http://www.pomit.cn

client_id是配置文件中写的，redirect_uri随意，因为单机版的只是测试接口。后面会整理下多机版的博文。

打开后自动调整到登录页面：

在这里插入图片描述

输入正确的用户名密码，调整到授权页面。

在这里插入图片描述

点击同意以后，调整到redirect_uri指定的页面。

在这里插入图片描述

获取到code：TnSFA6vrIZiKadwr

用code换取access_token，请求token接口：http://127.0.0.1:8080/oauth/token?grant_type=authorization_code&code=TnSFA6vrIZiKadwr&client_id=MwonYjDKBuPtLLlK&client_secret=secret&redirect_uri=http://www.pomit.cn。这个请求必须是post，因此不能在浏览器中输入了，可以使用postman:
