spring整合shiro（1）
1、jar

    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-spring</artifactId>
      <version>1.2.3</version>
    </dependency>

2、web.xml

  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>
          classpath:spring-shiro.xml
      </param-value>
  </context-param>
<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <listener>
        <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>

    <!-- Apache Shiro -->
    <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>
        <!-- targetBeanName表示shiro配置檔案中宣告的filterBean的id 不配置則預設和filter-name一致 -->
        <init-param>
            <param-name>targetBeanName</param-name>
            <param-value>shiroFilter</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
 

3、spring-shiro.xml
說明：
（1）loginurl：訪問需要認證的資源且沒有認證時跳轉的路徑，不配置預設根路徑下/login.jsp
（2）successUrl：認證成功後跳轉的路徑，不配置則跳轉上一個url
（3）filterChainDefinitions：過濾器鏈配置的是訪問路徑是否需要認證

4、realm

public class MyRealm extends AuthorizingRealm {
    @Resource
    private LoginService loginService;
    @Override
    public String getName() {
        return "myRealm";
    }
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String userName = token.getPrincipal().toString();
        User user = null;
        SimpleAuthenticationInfo info = null;
        try {
            if(loginService==null){
                loginService = SpringBeanFactoryUtils.getBean(LoginService.class);
                user = loginService.findUserByUserName(userName);
            }else{
                user = loginService.findUserByUserName(userName);
            }
            info = new SimpleAuthenticationInfo(user, user.getPassword(), getName());
        }catch (Exception e){
            e.printStackTrace();
        }
        return info;
