shiro权限控制

shiro 权限控制

1.增加jar包

<!--shiro start -->
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-core</artifactId>
        <version>${shiro.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-web</artifactId>
        <version>${shiro.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-ehcache</artifactId>
        <version>${shiro.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-spring</artifactId>
        <version>${shiro.version}</version>
    </dependency>

 <!--shiro end -->

2.配置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-3.2.xsd"
    default-lazy-init="false">

            </map>
        </property>

        <property name="filterChainDefinitions">

                /assets/** = anon
                /login/** = anon

                 <!-- user 用户是身份验证通过或RememberMe 登录-->
                /feedback/** = user

                /**/edit**=roles[1,2,3],productAuth,validate,permissionInfo

                /adminSettings/**=roles[1],permissionInfo
                
                /index/**=authc
                /** = 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" />
    
</beans>

3.编写shiro域

public class ShiroHttpRealm extends AuthorizingRealm {
    
    //判断用户是否正常，正常登录返回该用户信息
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo( PrincipalCollection principals ) {
        // TODO Auto-generated method stub
        return null;
    }
    
    //加载该用户权限信息，方便后面做判断
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token ) throws AuthenticationException {
        // TODO Auto-generated method stub
        return null;
    }
