2.创建 RealmCustom继承 AuthorizingRealm
package com.made.md.shiro;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
public class RealmCustom extends AuthorizingRealm{
/**
* 返回 权限信息
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principal) {
// TODO Auto-generated method stub
// 1. 获取 用户名
String userName = principal.getPrimaryPrincipal().toString();
// 2. 根据 用户名 调用数据库 查看该用户下的角色 以及 权限
// 3. 添加 角色 以及 权限
SimpleAuthorizationInfo simpleInfo = new SimpleAuthorizationInfo();
simpleInfo.addRole("admin");
simpleInfo.addStringPermission("ma1");
return simpleInfo;
}
/**
* 验证登录信息
* 返回 登录信息
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// TODO Auto-generated method stub
// 1.获取 用户名 密码
String userName = token.getPrincipal().toString();
String password = new String((char[])token.getCredentials());
// 2. 通过 调用数据库 来验证 登录信息是否正确
// 3. 如果 一切 正确 返回
SimpleAuthenticationInfo simpleInfo = new SimpleAuthenticationInfo(userName, password, getName());
return simpleInfo;
}
}
3.创建 applicationContext-shiro.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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- 配置自定义Realm -->
<bean id="realmCustom" class="com.made.md.shiro.RealmCustom" />
<!-- 安全管理器 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="realmCustom" />
</bean>
<!-- Shiro过滤器 核心 -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<!-- Shiro的核心安全接口,这个属性是必须的 -->
<property name="securityManager" ref="securityManager" />
<!-- 登录页面请求地址 -->
<property name="loginUrl" value="/toLogin" />
<!-- 登录成功之后的 跳转页面 -->
<property name="successUrl" value="/toHome"></property>
<!-- 权限认证失败，则跳转到指定页面 -->
<property name="unauthorizedUrl" value="/toUnAuthorized" />
<!-- Shiro连接约束配置,即过滤链的定义 -->
<property name="filterChainDefinitions">
<value>
<!-- 过滤器链的执行顺序是自上而下依次匹配, 如果能匹配上, 则不再往下匹配 -->
<!-- roles 和perms只能存在一个 谁在下面谁生效 -->
<!-- authc:必须要验证
logout：退出
anon：匿名随意访问
roles[xxx]:只有角色是xxx的用户可以访问此路径
perms[xxx]:只有有xxx权限的用户可以访问此路径
-->
<!--静态文件 -->
/css/* = anon
/lib/* = anon
/views/* = anon
/doLogin = anon
/doLogout = logout
/toAuthorized = perms[ma]
/** = authc
</value>
</property>
</bean>
<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
<!-- 开启Shiro注解 -->
<!-- <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor"/> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/> </bean> -->
<!-- AOP式方法级权限检查 -->
<bean
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor">
<property name="proxyTargetClass" value="true" />
</bean>
<bean
class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager" />

@Controller

return "redirect: toHome";
