背景: 网上很多讲配置 oauth2 ,配置方法 复杂纷繁对于初学者很不友好,让人望而却步

欢迎关注本系列博客 基于 spring cloud 最新版本 hoxton 完成oauth2 的实践


名称 版本
Spring Boot 2.2.0.M5
Spring Cloud Hoxton.M2
Spring Cloud OAuth2 2.2.0.M2

开始配置认证服务器

maven 依赖引入

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-oauth2</artifactId>
    </dependency>
</dependencies>

配置web安全,拦截全部的请求

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
    /**
     * 必须注入 AuthenticationManager,不然oauth  无法处理四种授权方式
     *
     * @return
     * @throws Exception
     */
    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    /**
     * 必须注入UserDetailsService ,不然oauth  密码模式等死循环问题
     *
     * @return
     */
    @Bean
    @Override
    protected UserDetailsService userDetailsService() {
        InMemoryUserDetailsManager userDetailsManager = new InMemoryUserDetailsManager();
        userDetailsManager.createUser(User.withUsername("lengleng").password("{noop}lengleng").authorities("USER").build());
        return userDetailsManager;
    }
}

配置oauth2 认证服务器

@Configuration
@EnableAuthorizationServer
public class BigAuthServerConfiguration extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("appid")
                .secret("{noop}secret")
                .authorizedGrantTypes("password", "authorization_code", "client_credentials", "implicit", "refresh_token")
                .scopes("all");
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService);
    }

}

以上完成了认证服务器的功能

测试密码模式

curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'grant_type=password&username=lengleng&password=lengleng&scope=all' "http://appid:secret@localhost:8764/oauth/token"

开始配置资源服务器

maven 依赖引入

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-oauth2</artifactId>
    </dependency>
</dependencies>

配置客户端信息

security:
  oauth2:
    client:
      client-id: appid
      client-secret: secret
      scope: all
    resource: # 认证中心的check_token 接口地址
      token-info-uri: http://127.0.0.1:8764/oauth/check_token

应用声明资源服务器

// 接入oauth2 ,声明为资源服务器
@EnableResourceServer  
@EnableDiscoveryClient
@SpringBootApplication
public class BigUpmsServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(BigUpmsServerApplication.class, args);
    }

}

上文配置的认证服务器暴露check_token

public class BigAuthServerConfiguration extends AuthorizationServerConfigurerAdapter {
    /**
     * checkTokenAccess 权限设置为isAuthenticated,不然资源服务器 来请求403
     * @param oauthServer
     */
    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) {
        oauthServer
                .allowFormAuthenticationForClients()
                .checkTokenAccess("isAuthenticated()");
    }
}

资源服务器demo 接口

@RestController
public class DemoController {

    @GetMapping("/info")
    public Authentication authentication(Authentication authentication) {
        return authentication;
    }
}

通过上文获取的token 访问测试接口
