1.创建一个springboot项目
选中web和thymeleaf
1.1新建index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>首页</h1>
<p th:text="${msg}"></p>
</body>
</html>
1.2创建一个controller
package com.yao.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class MyController {
@RequestMapping({"/","/index"})
public String toIndex(Model model){
model.addAttribute("msg","hello,Shiro");
return "index";
}
}
一定要记住shiro的三大对象
1.subject：用户
2.SecurityManager：管理所有用户
3.Realm：连接数据
1.3导入整合用的依赖包
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.4.1</version> </dependency>
1.4创建一个config(ShiroConfig)，并编写他
package com.yao.config;
import org.springframework.context.annotation.Configuration;
@Configuration
public class ShiroConfig {
//ShiroFilterFactoryBean
//DefaultWebSecurityManager
//创建 realm 对象，这个realm对象需要自定义
}
1.5创建自己的一个realmconfig，也就是在config中创建另外一个配置类UserRealm
package com.yao.config;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
//自定义的 UserRealm
public class UserRealm extends AuthorizingRealm {
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("授权。。。");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("认证。。。");
return null;
}
}
1.6将UserRealm注册到ShiroConfig里面去，是我们自己写的这个类被spring托管
1.7新建两个测试页面并重新写一下index页面
add.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>add</h1> </body> </html>
update.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>update</h1> </body> </html>
index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>首页</h1>
<p th:text="${msg}"></p>
<hr>
<a th:href="https://www.freexyz.cn/dev/@{/user/add}" rel="external nofollow" >add</a> | <a th:href="https://www.freexyz.cn/dev/@{/user/update}" rel="external nofollow" >update</a>
</body>
</html>
1.8编写controller层
package com.yao.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@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";
}
}
1.9添加过滤器
还是在shiroconfig中加入：
//添加Shiro的内置过滤器
/*
anon：无需认证就可以访问
authc：必须认证了才能通过
user：必须拥有记住我功能才能用
perms：拥有对某个资源的权限才可以访问
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");
filterMap.put("/user/*","authc");
bean.setFilterChainDefinitionMap(filterMap);
//设置登录的请求
bean.setLoginUrl("/toLogin");
return bean;
这里希望没有认证就从add和update跳到login页面因此还要写一个login页面和改写controller
controller层：
@RequestMapping("/toLogin")
public String toLogin(){
return "login";
}
login页面：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>登录</title> </head> <body> <form> <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>
1.10上面已经完成了页面拦截的功能接下来实现用户认证的工作
login.html:
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>登录</title>
</head>
<body>
<p th:text="${msg}" ></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>
controller:
@RequestMapping("/login")
public String login(String username,String password,Model model){
//获取当前用户
Subject subject = SecurityUtils.getSubject();
//封装用户的登录数据(令牌),这里是存在全局里面，都可以调的到
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
try {
subject.login(token);// 执行登陆的方法，如果没有异常就ok了
return "index";
} catch (UnknownAccountException e) {
model.addAttribute("msg","用户名错误");
return "login";
} catch (IncorrectCredentialsException e){
model.addAttribute("msg"," 密码错误");
return "login";
}
}
UserRealm:
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("认证。。。");
//用户名，密码 数据库中取
String name = "root";
String password = "123456";
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
if(!userToken.getUsername().equals(name)){
return null;//它这里会自动抛出前面的用户名错误的异常
}
//密码认证不让你做，它自己做，他不让你接触密码
return new SimpleAuthenticationInfo("",password,"");
}
}
直接测试即可发现以上功能基本实现。
package com.yao.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class MyController {
@RequestMapping({"/","/index"})
public String toIndex(Model model){
model.addAttribute("msg","hello,Shiro");
return "index";
}
}
2.springboot整合mybatis
2.1导入依赖
<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>1.1.12</version> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.0</version> </dependency>
2.2编写配置文件application.yml
spring: datasource: username: root password: 892095368llq #?serverTimezone=UTC解决时区的报错 url: jdbc:mysql://localhost:3306/yao?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
2.3编写配置文件application.properties并新建mapper文件夹
application.properties
mybatis.type-aliases-package=com.yao.pojo mybatis.mapper-locations=classpath:mapper/*.xml
2.4创建pojo层，并配置lombok
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.10</version> </dependency>
编写一个User.java
package com.yao.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String pwd;
}
2.4创建mapper层，并写出相对应的mapper接口和resources中的对应的mapper实现
UserMapper接口
package com.yao.mapper;
import com.yao.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
@Repository
@Mapper
public interface UserMapper {
public User queryUserByName(String name);
}
mapper。xml
<?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.yao.mapper.UserMapper">
<select id="queryUserByName" parameterType="String" resultType="User">
select * from user where name = #{name}
</select>
</mapper>
UserService.interface
package com.yao.service;
import com.yao.pojo.User;
public interface UserService {
public User queryUserByName(String name);
}
UserServiceImpl.java
package com.yao.service;
import com.yao.mapper.UserMapper;
import com.yao.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserServiceImpl implements UserService{
@Autowired
UserMapper userMapper;
@Override
public User queryUserByName(String name) {
return userMapper.queryUserByName(name);
}
}
2.6在test中测试
package com.yao;
import com.yao.service.UserService;
import com.yao.service.UserServiceImpl;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class ShiroSpringbootApplicationTests {
@Autowired
UserServiceImpl userService;
@Test
void contextLoads() {
System.out.println(userService.queryUserByName("幺幺"));
}
}
测试成功，继续写
2.7更改UserRealm
package com.yao.config;
import com.yao.pojo.User;
import com.yao.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
//自定义的 UserRealm
public class UserRealm extends AuthorizingRealm {
@Autowired
UserService userService;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("授权。。。");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("认证。。。");
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
//连接真实数据库
User user = userService.queryUserByName(userToken.getUsername());
if (user==null){
return null;
}
//密码认证不让你做，它自己做，他不让你接触密码
return new SimpleAuthenticationInfo("",user.getPwd(),"");
}
}
2.8添加密码加密
//还有一个md5加密，集成了hashcode是不可逆的
//比如你的密码是123456
// md5(123456,32) = e10adc3949ba59abbe56e057f20f883e
// md5(123456,16) = 49ba59abbe56e057
//MD5盐值加密e10adc3949ba59abbe56e057f20f883eusername
//密码认证不让你做，它自己做，他不让你接触密码
return new SimpleAuthenticationInfo("",user.getPwd(),"");
2.9请求授权实现
==============
2.10绑定thymeleaf
package com.yao.mapper;
import com.yao.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
@Repository
@Mapper
public interface UserMapper {
public User queryUserByName(String name);
}
