springmvc+shiro简单配置及作用（shiro部分）

1. web.xml配置shirofilter

<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

2.spring shiro相关配置

<bean id="myRealm" class="com.mvc.rest.core.util.MyRealm"/>

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm"/>
</bean>

【这里主要是设置自定义的单Realm应用,若有多个Realm,可使用'realms'属性代替，也可设置<property name="sessionMode" value="native"/>】

3.spring shiro拦截配置

<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"/>
<property name="loginUrl" value="/login.jsp"/>
<property name="unauthorizedUrl" value="/login.jsp"/>
<property name="filterChainDefinitions">
<value>
/login=anon
/getVerifyCodeImage=anon
/**=authc

</value>
</property>
</bean>

【简单配置，若是想扩展配置，一般在方法上注解，若是想实现类似动态拦截的可以重写filter和filterChainDefinitions的方法】

public enum DefaultFilter {
anon(AnonymousFilter.class),
authc(FormAuthenticationFilter.class),
authcBasic(BasicHttpAuthenticationFilter.class),
logout(LogoutFilter.class),
noSessionCreation(NoSessionCreationFilter.class),
perms(PermissionsAuthorizationFilter.class),
port(PortFilter.class),
rest(HttpMethodPermissionFilter.class),
roles(RolesAuthorizationFilter.class),
ssl(SslFilter.class),
user(UserFilter.class);
} 

3. spring shiro开启注解配置

<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>
