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

springboot整合Shiro 点击并拖拽以移动

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="@{/user/add}">add</a> | <a th:href="@{/user/update}">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}" 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>

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

springboot整合Shiro 点击并拖拽以移动

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

springboot整合Shiro 点击并拖拽以移动

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);
}
