shiro认证

1.导入pom.xml依赖

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>
    <version>1.3.2</version>
</dependency>

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-web</artifactId>
    <version>1.3.2</version>
</dependency>

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.3.2</version>
</dependency>

2.在web.xml加入以下配置

<!-- shiro过滤器定义 -->
<filter>
  <filter-name>shiroFilter</filter-name>
  <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  <init-param>
    <!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 -->
    <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>

3.通过****将五张表生成对应的model、mapper
Shiro认证
