添加shiro的配置文件
shiro的配置是可以放在spring的配置文件中,但是为了方便管理,这里单独给shiro添加一个配置文件,里面的Schema约束规范还是spring的

完成各层的文件
service层的接口及实现类
接口

import java.util.List;

public interface UserService {
public List<UserBean> query();
public UserBean queryByName(String userName);
public UserBean queryByNameSHA(String userName);
public void addUser(UserBean user);
public void updateUser(UserBean user);
public void deleteUser(Integer id);

以及对应的UserBeanExample类,这里不做展示
controller层
package com.zhouym.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;

import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.zhouym.service.UserService;
@Controller
public class UserController {
@Resource
private UserService service;
@RequestMapping("/login.do")
public String login(Model m,HttpServletRequest request) {
Object object = request.getAttribute(FormAuthenticationFilter.DEFAULT_ERROR_KEY_ATTRIBUTE_NAME);
if (UnknownAccountException.class.getName().equals(object)) {
m.addAttribute("msg", "账号错误");
return "login.jsp";
}else if (IncorrectCredentialsException.class.getName().equals(object)) {
m.addAttribute("msg", "密码错误");
return "login.jsp";
}else {
m.addAttribute("msg","未知错误");
return "login.jsp";
}
}
//当我们第一次登录成功后,点后退再次登录会报错,此时需要显式退出,再次登录即可
@RequestMapping("/logout.do")
public String logout() {
SecurityUtils.getSubject().logout();
return "redirect:login.jsp";
}
@RequiresRoles("role1")
@RequestMapping("/query")
public String query(Model m) {
m.addAttribute("list",service.query());
return "/user.jsp";
}
@RequiresRoles("role2")
@RequestMapping("/query1")
public String query1(Model m) {
m.addAttribute("list",service.query());
return "/user.jsp";
}
@RequestMapping("/query2")
public String query2(Model m) {
m.addAttribute("list",service.query());
return "/user.jsp";
}
}
创建对应的jsp文件
login.jsp文件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>用户登陆:${msg} </h1>
<form action="login.do" method="post">
账号:<input type="text" name="username"><br>
密码:<input type="text" name="password"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
当我们点击提交后,根据action中的值找到对应的处理器,即controller,获取用户输入的用户名及密码,由于login.do在shiro的配置文件中被拦截了,所以先去我们自定义的realm类中进行认证,在认证方法中根据获取的用户名,带这个用户名的条件进行查询这个用户名下的信息,将信息保存到AuthenticationInfo中,然后再进入授权的方法中,查看对应用户名的权限,返回授权后的信息
输入用户名和密码
执行logout.do直接返回登录页面
