1、环境搭建
1、新建一个springboot项目，勾选Spring Web和Thymeleaf依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
2、测试环境是否正常
- 新建一个controller页面
@Controller
public class MyController {
@RequestMapping({"/","/index"})
public String toIndex(Model model){
model.addAttribute("msg","hello,Shiro!");
return "index";
}
@RequestMapping("/user/add")
public String add(){
return "user/add";
}
@RequestMapping("/user/update")
public String update(){
return "user/update";
}
}
- 新建一个index.html页面
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>首页</title>
</head>
<body>
<h1>首页</h1>
<p th:text="${msg}"></p>
<hr>
<a th:href="@{/user/add}">add</a> | <a th:href="@{/user/update}">update</a>
</body>
</html>
- 新建一个add.html页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>add</h1>
</body>
</html>
- 新建一个update.html页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>update</h1>
</body>
</html>

运行截图
3、导入shiro整合spring的包
<!--
Subject 用户
SecurityManager 管理所有用户
Realm 连接数据
-->
<!--shiro整合spring包-->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.5.3</version>
</dependency>
4、编写导入配置类
- 编写一个自定义类UserRealm
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=>授权doGetAuthorizationInfo");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthenticationInfo");
return null;
}
}
- 编写配置ShiroConfig
1、创建realm对象，需要自定义类
2、DefaultWebSecurityManager
3、ShiroFilterFactoryBean
@Configuration
public class ShiroConfig {
//ShiroFilterFactoryBean : 3
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaulWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
//设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
return bean;
}
//DefaultWebSecurityManager : 2
@Bean
public DefaultWebSecurityManager getDefaulWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//关联UserRealm
securityManager.setRealm(userRealm);
return securityManager;
}
//创建realm对象，需要自定义类 : 1
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
2、Shiro实现登录拦截
- 在ShiroConfig中的getShiroFilterFactoryBean方法中添加如下配置：
//添加shiro的内置过滤器
/*
* anon: 无需认证，就可以访问
* authc: 必须认证了，才能访问
* user: 必须拥有‘记住我’功能，才能访问
* perms: 拥有对某个资源的权限，才能访问
* role: 拥有某个角色权限，才能访问
* */
Map<String, String> filterMap = new LinkedHashMap<>();
filterMap.put("/user/add","authc");
filterMap.put("/user/update","authc");
bean.setFilterChainDefinitionMap(filterMap);
- 再点击首页的add或者update之后，
这是拦截之后的系统默认页面，我们要把这个页面显示一些内容 - 添加拦截成功页面
- 登录页面login.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登录页面</title>
</head>
<body>
<h1>登录</h1>
<hr>
<form action="">
<p>用户名：<input type="text" name="username"></p>
<p>密码：<input type="text" name="password"></p>
<p>密码：<input type="submit"></p>
</form>
</body>
</html>
- 在MyController中添加toLogin
@RequestMapping("/toLogin")
public String toLogin() {
return "login";
}
- 在ShiroConfig中的getShiroFilterFactoryBean方法中添加如下配置
//设置登录的请求，（如果没有登录,点击了有权限的访问）
bean.setLoginUrl("/toLogin");
- 拦截成功页面
3、Shiro实现用户认证
- 在MyController中编写用户提交表单之后处理
@RequestMapping("/login")
public String login(String username,String password,Model model){
//获取当前的用户
Subject subject = SecurityUtils.getSubject();
//封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
//执行登录的方法，如果没有异常就ok
//subject.login(token);
try {
subject.login(token);
return "index";
} catch (UnknownAccountException e) { //用户名错误
model.addAttribute("msg","用户名错误");
return "login";
} catch (IncorrectCredentialsException e){ //密码错误
model.addAttribute("msg","密码错误");
return "login";
}
}
- login.html的修改
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>登录</h1>
<hr>
<p th:text="${msg}" style="color: red;"></p>
<form th:action="@{/login}">
<p>用户名：<input type="text" name="username"></p>
<p>密码：<input type="text" name="password"></p>
<p><input type="submit"></p>
</form>
</body>
</html>
-
用户输入登录信息
页面：
控制台： -
用户认证编写UserRealm中的认证（doGetAuthenticationInfo）
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthorizationInfo");
// 用户名、密码， 数据中取
String name = "root";
String password = "123456";
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
if (!userToken.getUsername().equals(name)) {
return null;//抛出异常 UnknownAccountException
}
// 密码认证，shiro做
return new SimpleAuthenticationInfo("",password,"");
}
4、Shiro整合Mybatis
1、导入依赖：
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.23</version>
</dependency>
<!--引入mybatis，这是MyBatis官方提供的适配spring Boot的，而不是spring Boot自己的-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.3</version>
</dependency>
2、配置文件application.yml的编写
spring:
datasource:
username: root
password: 123456
#?serverTimezone=UTC解决时区的报错
url: jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
driver-class-name: com.mysql.cj.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
#Spring Boot 默认是不注入这些属性值的，需要自己绑定
#druid 数据源专有配置
initialSize: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
#配置监控统计拦截的filters，stat:监控统计、log4j：日志记录、wall：防御sql注入
#如果允许时报错 java.lang.ClassNotFoundException: org.apache.log4j.Priority
#则导入 log4j 依赖即可，Maven 地址：https://mvnrepository.com/artifact/log4j/log4j
filters: stat,wall,log4j
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
mybatis:
type-aliases-package: com.chz.pojo
mapper-locations: classpath:mapper/*.xml
3、User类的编写
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String pwd;
private String perms;
}
4、UserMapper.xml映射
<?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">
<!--namespace=绑定一个对应的Dao/Mapper接口-->
<mapper namespace="com.chz.mapper.UserMapper">
<select id="queryUserByName" parameterType="String" resultType="User">
select * from mybatis.user where name=#{name}
</select>
</mapper>
5、UserService接口实现
public interface UserService {
public User queryUserByName(String name);
}
6、UserServiceImpl业务逻辑
@Service
public class UserServiceImpl implements UserService{
@Autowired
UserMapper userMapper;
@Override
public User queryUserByName(String name) {
return userMapper.queryUserByName(name);
}
}
7、UserRealm连接真实数据库 （config-UserRealm）
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthenticationInfo");
UsernamePasswordToken userToken= (UsernamePasswordToken) token;
//用户名，密码 ————数据库中取,连接真实的数据库
User user = userService.queryUserByName(userToken.getUsername());
//没有这个人
if(user==null){
//UnknownAccountException
return null;
}
//密码认证，shiro做
//可以加密：MD5，MD5演唱、盐值加密
return new SimpleAuthenticationInfo(user,user.getPwd(),"");
}
5、Shiro实现用户授权
1、ShiroConfig中的getShiroFilterFactoryBean方法添加认证代码
//授权，正常情况下，未授权会跳转到未授权页面
filterMap.put("/user/add","perms[user:add]");
filterMap.put("/user/update","perms[user:update]");
2、登录之后点击add按钮会弹出如下页面
3、添加为授权页面
- MyController
@RequestMapping("/noauth")
@ResponseBody
public String unauthorized(){
return "未经授权无法访问此页面";
}
- ShiroConfig中的getShiroFilterFactoryBean方法中添加
//未授权页面
bean.setUnauthorizedUrl("/noauth");
- 再次测试
所以需要在UserRealm中为用户进行真正授权
4、UserRealm类的修改
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
@Autowired
UserService userService;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=>授权doGetAuthorizationInfo");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//拿到当前登录的这个对象
Subject subject = SecurityUtils.getSubject();
//拿到user对象
User currentUser = (User) subject.getPrincipal();
//设置当前用户的权限
info.addStringPermission(currentUser.getPerms());
return info;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthenticationInfo");
UsernamePasswordToken userToken= (UsernamePasswordToken) token;
//用户名，密码 ————数据库中取,连接真实的数据库
User user = userService.queryUserByName(userToken.getUsername());
//没有这个人
if(user==null){
//UnknownAccountException
return null;
}
//密码认证，shiro做
//可以加密：MD5，MD5演唱、盐值加密
return new SimpleAuthenticationInfo(user,user.getPwd(),"");
}
}
5、再次测试
6、Shiro整合Thymeleaf
1、shiro-thymeleaf整合包导入
<!--shiro-thymeleaf整合-->
<dependency>
<groupId>com.github.theborakompanioni</groupId>
<artifactId>thymeleaf-extras-shiro</artifactId>
<version>2.0.0</version>
</dependency>
2、在ShiroConfig中整合ShiroDialect
// 整合ShiroDialect： 用来整合 Shiro thymeleaf
@Bean
public ShiroDialect getShiroDialect() {
return new ShiroDialect();
}
3、index.html页面
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"
xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">
<head>
<meta charset="UTF-8">
<title>首页</title>
</head>
<body>
<h1>首页</h1>
<div shiro:notAuthenticated>
<a th:href="@{/toLogin}">登录</a>
</div>
<div shiro:Authenticated>
<a th:href="@{/logout}">注销</a>
</div>
<p th:text="${msg}"></p>
<hr>
<div shiro:hasPermission="user:add">
<a th:href="@{/user/add}">add</a>
</div>
<div shiro:hasPermission="user:update">
<a th:href="@{/user/update}">update</a>
</div>
</body>
</html>
4、页面显示
