在ssm框架基础上添加shiro的感想

在ssm框架人基础上添加shiro权限管理
第一步：zaiweb.xml上shiroFilter的拦截器设置，以及加载spring-shiro.xml
<!-- shiro的拦截器 -->
<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>
第二步：导入shiro的maven依赖
<!-- shiro jar包 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.3.1</version>
</dependency>
第三步，配置spring-shiro.xml
第四步：写Myrealm类继承AuthorizingRealm,认证和授权，具体代码不细说了
第五步：对应的shiro标签的jsp页面
