<--! DelegatingFilterProxy 作用是自动到 Spring容器查找名字为 shiroFilter（filter-name）
的 bean 并把所有 Filter的操作委托给它 -->
<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>
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
注：DelegatingFilterProxy的filter-name要和spring-shiro中的shiroFilterFactoryBean中的id相同，否则报错，或者使用以下方法（在DelegatingFilterProxy中加入<init-param>）
<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>
<init-param>
<param-name>targetBeanName</param-name>
<param-value>name</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
此时spring-shiro中的shiroFilterFactoryBean中的id和param-value相同，即name

- 自定义的realm继承AuthorizingRealm就可以实现认证和授权方法，AuthorizingRealm继承自AuthenticatingRealm，AuthenticatingRealm中有doGetAuthenticationInfo方法，AuthorizingRealm中有doGetAuthorizationInfo
- realm的认证策略：
- FirstSuccessfulStrategy：只要有一个 Realm 验证成功即可，只返回第一个 Realm 身份验证成功的认证信息，其他的忽略；
- AtLeastOneSuccessfulStrategy：只要有一个Realm验证成功即可，和FirstSuccessfulStrategy 不同，将返回所有Realm身份验证成功的认证信息；（默认策略）
- AllSuccessfulStrategy：所有Realm验证成功才算成功，且返回所有Realm身份验证成功的认证信息，如果有一个失败就失败了。
- 因为缓存：先去第一个realm寻找role，如果第一个realm有放入当前页面的权限就不继续访问下一个realm，当继续访问其他页面而第一个realm没有放入当前页面的role，则去第二个realm寻找。（不会重复访问，不配置缓存就会重复访问）
- filterChainDefinitionMap工厂（filterChainDefinitionMap和filterChainDefinitions只能存在一个）
public class FilterChainDefinitionMapFactory {
public LinkedHashMap<String,String> buildFilterChainDefinitionMap(){
LinkedHashMap<String, String> map = new LinkedHashMap<>();
map.put("/doLogin", "anon");
map.put("/logout", "logout");
map.put("/admin", "authc,roles[admin]");
map.put("/user", "roles[user]");
map.put("/test", "user");
map.put("/vip", "user");
map.put("/success", "user");
map.put("/**", "authc");
return map;
}
}
rememberMe功能如果要认证才可以操作的的除了加权限还要加authc 例如：map.put("/admin", "authc,roles[admin]");否则可以通过记住我直接访问/admin
shiro权限注解
- @RequiresAuthentication：表示当前Subject已经通过login进行了身份验证；即 Subject. isAuthenticated() 返回 true
- @RequiresUser：表示当前 Subject 已经身份验证或者通过记住我登录的。
- @RequiresGuest：表示当前Subject没有身份验证或通过记住我登录过，即是游客身份。
- @RequiresRoles(value={“admin”, “user”}, logical= Logical.AND)：表示当前 Subject 需要角色 admin 和user，@RequiresRoles(value={“admin”, “user”}, logical= Logical.OR)：表示当前 Subject 需要角色 admin 或user中的其中一个
- @RequiresPermissions (value={“user:a”, “user:b”}, logical= Logical.OR)：表示当前 Subject 需要权限 user:a 或user:b。
@RequiresRoles(value = {"admin","vip"},logical = Logical.AND)
@RequestMapping(value = {"/testAnnotation2"})
public String testAnnotation2(){
System.out.println("testAnnotation2222。");
return "success";
}
如果要在Controller层使用注解，要在springmvc.xml中添加
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
<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"/>
</bean>
如果要在service中使用，在spring-shiro中即可
httpsession和SecurityUtils.getSubject().getSession()可以互相改，可以在service调用session
session也有会话监听器用于监听会话创建、过期及停止事件onStart，onStop，onexpiration
