Shiro許可權控制框架 ---SpringMVC+Spring+My batis+Mysql+Maven整合開發Web專案
在之前的博文簡單的介紹shiro許可權控制框架,現在我們接著講解使用 SpringMVC+Spring+My batis+Mysql+Maven整合開發Web專案
1.先由Maven選擇MavenProject建立一個Web專案(如果你還不會使用Maven的話可以去看看我講解Maven博文)
這裡你看到我建立完成後為什麼專案畫把 X,因為自己的膝上型電腦上安裝的JDK和Maven版本有些低所以就這樣,但是這不會影響到專案的正常編碼。
2.編寫pom.xml檔案引入開發是需要的Jar架包,因為我們使用的是Maven所以管理Jar架包很方便。
3.搭建專案架構(建立每個層的包)<span style="font-size:18px;"><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.java1234.shiro</groupId> <artifactId>ShiroWeb2</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ShiroWeb2 Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- 新增Servlet支援 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.1</version> </dependency> <!-- 新增jtl支援 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 新增Spring支援 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <!-- 新增日誌支援 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- 新增mybatis支援 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!-- jdbc驅動包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.37</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.12</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.4</version> </dependency> </dependencies> <build> <finalName>ShiroWeb2</finalName> </build> </project> </span>
4.建立資料庫 (這裡我們使用的MySQL資料庫)直接複製到MYSQL上執行即可
分別有三張表:使用者表T_User,角色表t_role,許可權表:t_permission這三張表間相關聯
<span style="font-size:18px;">/* SQLyog Ultimate v11.33 (64 bit) MySQL - 5.1.49-community : Database - db_shiro ********************************************************************* */ /*!40101 SET NAMES utf8 */; /*!40101 SET SQL_MODE=''*/; /*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */; /*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */; /*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */; /*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */; CREATE DATABASE /*!32312 IF NOT EXISTS*/`db_shiro` /*!40100 DEFAULT CHARACTER SET utf8 */; USE `db_shiro`; /*Table structure for table `t_permission` */ DROP TABLE IF EXISTS `t_permission`; CREATE TABLE `t_permission` ( `id` int(11) NOT NULL AUTO_INCREMENT, `permissionName` varchar(50) DEFAULT NULL, `roleId` int(11) DEFAULT NULL, PRIMARY KEY (`id`), KEY `roleId` (`roleId`), CONSTRAINT `t_permission_ibfk_1` FOREIGN KEY (`roleId`) REFERENCES `t_role` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; /*Data for the table `t_permission` */ insert into `t_permission`(`id`,`permissionName`,`roleId`) values (1,'user:*',1),(2,'student:*',2); /*Table structure for table `t_role` */ DROP TABLE IF EXISTS `t_role`; CREATE TABLE `t_role` ( `id` int(11) NOT NULL AUTO_INCREMENT, `roleName` varchar(20) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; /*Data for the table `t_role` */ insert into `t_role`(`id`,`roleName`) values (1,'admin'),(2,'teacher'); /*Table structure for table `t_user` */ DROP TABLE IF EXISTS `t_user`; CREATE TABLE `t_user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `userName` varchar(20) DEFAULT NULL, `password` varchar(100) DEFAULT NULL, `roleId` int(11) DEFAULT NULL, PRIMARY KEY (`id`), KEY `roleId` (`roleId`), CONSTRAINT `t_user_ibfk_1` FOREIGN KEY (`roleId`) REFERENCES `t_role` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8; /*Data for the table `t_user` */ insert into `t_user`(`id`,`userName`,`password`,`roleId`) values (1,'java1234','123456',1),(2,'jack','123',2),</span></span>

<span style="font-size:18px;">
</span>
<span style="font-size:18px;">5.創建於資料庫表相對應的實體類因為我們這裡拿登入做例項講解,然後user表又和角色表、許可權表有關聯所以一個實體類就足夠了</span>
<span style="font-size:18px;">
</span>
<span style="font-size:18px;">package com.java1234.entity;
public class User {
private Integer id;
private String userName;
private String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
</span>
6.編寫配置applicationContext.xml

7.配置SpringMVC.xml
<span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

8.配置核心Web.xml檔案
<span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

9.編寫資料訪問層Dao (因為使用Sping的註解模式,使用註解代替原本應用的UserDaoImpl)
<span style="font-size:18px;">package com.java1234.dao;
import java.util.Set;
import com.java1234.entity.User;
public interface UserDao {
/**
* 通過使用者名稱查詢使用者
* @param userName
* @return
*/
public User getByUserName(String userName);
/**
* 通過使用者名稱查詢角色資訊
* @param userName
* @return
*/
public Set<String> getRoles(String userName);
/**
* 通過使用者名稱查詢許可權資訊
* @param userName
* @return
*/
public Set<String> getPermissions(String userName);
}
</span>
10.編寫業務層UserService
<span style="font-size:18px;">package com.java1234.service;
import java.util.Set;
import com.java1234.entity.User;
public interface UserService {
/**
* 通過使用者名稱查詢使用者
* @param userName
* @return
*/
public User getByUserName(String userName);
/**
* 通過使用者名稱查詢角色資訊
* @param userName
* @return
*/
public Set<String> getRoles(String userName);
/**
* 通過使用者名稱查詢許可權資訊
* @param userName
* @return
*/
public Set<String> getPermissions(String userName);
}
</span>
編寫UserServiceImpl實現類
<span style="font-size:18px;">package com.java1234.service.impl;
import java.util.Set;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.java1234.dao.UserDao;
import com.java1234.entity.User;
import com.java1234.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService{
@Resource
private UserDao userDao;
public User getByUserName(String userName) {
return userDao.getByUserName(userName);
}
public Set<String> getRoles(String userName) {
return userDao.getRoles(userName);
}
public Set<String> getPermissions(String userName) {
return userDao.getPermissions(userName);
}
}
</span>
11.編寫UserController控制器
<span style="font-size:18px;">package com.java1234.controller;
import javax.servlet.http.HttpServletRequest;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.java1234.entity.User;
/**
* 使用者Controller層
* @author Administrator
*
*/
@Controller
@RequestMapping("/user")
public class UserController {
/**
* 使用者登入
* @param user
* @param request
* @return
*/
@RequestMapping("/login")
public String login(User user,HttpServletRequest request){
Subject subject=SecurityUtils.getSubject();
//Shiro獲取使用者名稱密碼
UsernamePasswordToken token=new UsernamePasswordToken(user.getUserName(), user.getPassword());
try{
//驗證使用者角色
subject.login(token);
Session session=subject.getSession();
System.out.println("sessionId:"+session.getId());
System.out.println("sessionHost:"+session.getHost());
System.out.println("sessionTimeout:"+session.getTimeout());
session.setAttribute("info", "session的資料");
return "redirect:/success.jsp";
}catch(Exception e){
e.printStackTrace();
request.setAttribute("user", user);
request.setAttribute("errorMsg", "使用者名稱或密碼錯誤!");
return "index";
}
}
}
</span>
12.編寫UserMapper.xml檔案
<span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.java1234.dao.UserDao">
<resultMap type="User" id="UserResult">
<result property="id" column="id"/>
<result property="userName" column="userName"/>
<result property="password" column="password"/>
</resultMap>
<select id="getByUserName" parameterType="String" resultMap="UserResult">
select * from t_user where userName=#{userName}
</select>
<select id="getRoles" parameterType="String" resultType="String">
select r.roleName from t_user u,t_role r where u.roleId=r.id and u.userName=#{userName}
</select>
<select id="getPermissions" parameterType="String" resultType="String">
select p.permissionName from t_user u,t_role r,t_permission p where u.roleId=r.id and p.roleId=r.id and u.userName=#{userName}
</select>
</mapper> </span>
13.編寫自定義MyRealm
<span style="font-size:18px;">package com.java1234.realm;
import javax.annotation.Resource;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import com.java1234.entity.User;
import com.java1234.service.UserService;
public class MyRealm extends AuthorizingRealm{
@Resource
private UserService userService;
/**
* 為當限前登入的使用者授予角色和權
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
//獲取當前登入的使用者名稱
String userName=(String)principals.getPrimaryPrincipal();
SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();
//根據此使用者名稱查詢是否擁有 此角色
//返回的是一個字串集合
authorizationInfo.setRoles(userService.getRoles(userName));
//根據使用者名稱查詢是否擁有 此許可權
authorizationInfo.setStringPermissions(userService.getPermissions(userName));
return authorizationInfo;
}
/**
* 驗證當前登入的使用者
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
//獲取當前登入的使用者名稱
String userName=(String)token.getPrincipal();
//根據使用者名稱查詢此使用者是否存在
User user=userService.getByUserName(userName);
if(user!=null){
//如果存在就
AuthenticationInfo authcInfo=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx");
return authcInfo;
}else{
return null;
}
}
}
</span>
14.配置mybatis-config.xml
<span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 別名 -->
<typeAliases>
<package name="com.java1234.entity"/>
</typeAliases>
</configuration>
</span>
15.表示登入頁面index.jsp
<span style="font-size:18px;"><%@ 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>
<form action="${pageContext.request.contextPath }/user/login.do" method="post">
userName:<input type="text" name="userName" value="${user.userName }"/><br/>
password:<input type="password" name="password" value="${user.password }"><br/>
<input type="submit" value="login"/><font color="red">${errorMsg }</font>
</form>
</body>
</html></span>
表示成功頁面success.jsp
<span style="font-size:18px;"><%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>

歡迎有admin角色的使用者!<shiro:principal/>
</shiro:hasRole>
<shiro:hasPermission name="student:create">
歡迎有student:create許可權的使用者!<shiro:principal/>
</shiro:hasPermission>
</body>
</html></span>
以及失敗頁面unauthor.jsp
<span style="font-size:18px;"><%@ 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>
<h2>許可權認證失敗</h2>
</body>
</html></span>
整個專案已登入為主:1.首先登入頁面index.jsp傳送login登入請求。
2.然後該請求最初經過Web.xml檔案進行攔截在解析一系列的配置檔案----->在到UserController 控制器-------------------->執行對應的login()方法把頁面傳過來的使用者密碼塞給Shirok框架中的 UsernamePasswordToken物件----->在丟給Shiro框架中的Subject物件的subject.login(token);
方法驗證使用者角色。
3.就到自定義MyRealm裡面執行步驟是首先執行doGetAuthenticationInfo()方法獲取shiro框架 中儲存的使用者名稱String userName=(String)token.getPrincipal();------->根據使用者名稱查詢此使用者
是否存在User user=userService.getByUserName(userName);if判斷如果存在就在執行----->
doGetAuthorizationInfo()方法為當限前登入的使用者授予角色和權。
4.最終驗證次使用者是否擁有此角色、此許可權,操作登入。
