SpringMVC集成shrio框架

使用SHIRO的步骤：
1，导入jar
2，配置web.xml
3，建立dbRelm
4，在Spring中配置

 

添加所需jar包：

<!--Apache Shiro所需的jar包-->
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-core</artifactId>
      <version>1.2.2</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-web</artifactId>
      <version>1.2.2</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-spring</artifactId>
      <version>1.2.2</version>
    </dependency>
  </dependencies>

 

web.xml中配置shrio的过滤器：

<!-- Shiro配置 -->
  <filter>
    <filter-name>shiroFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

权限控制类：

public class ShiroRealm extends AuthorizingRealm {


    private static final Logger log = Logger.getLogger(ShiroRealm.class);

        SysUsers user = userService.getUserByUsername(currentUsername);
