缓存设置使用默认的hibernate的缓存
登录Action
package com.shiro.action; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.subject.Subject; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; @Controller public class LoginAction { @RequestMapping("/login") public String login(@RequestParam("username") String username, @RequestParam("password")String password){ //创建subject实例 Subject subject = SecurityUtils.getSubject(); //判断当前用户是否登录 if(subject.isAuthenticated()==false){ //将用户名及密码封装交个UsernamePasswordToken UsernamePasswordToken token = new UsernamePasswordToken(username,password); try { subject.login(token); } catch (AuthenticationException e) { System.out.println("验证不通过，无法登录！"); return "error"; } } return "success"; } }
relam域的调用是由Shrio后台进行调用。

该项目jar使用spring framerwork-4.0.0在使用4.2.3会报找不到相关的缓存class文件。
