1、建立spring boot项目
目录结构这个样子的
<hr>
2、项目的jar包依赖
<dependencies>
<!--整合shiro
subject:用户
security manager:管理所有的用户
realm:连接数据库
-->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.4.1</version>
</dependency>
<dependency>
<groupId>com.github.theborakompanioni</groupId>
<artifactId>thymeleaf-extras-shiro</artifactId>
<version>2.0.0</version>
</dependency>
<!--整合mybatis-->
<!-- https://mvnrepository.com/artifact/org.mybatis.spring.boot/mybatis-spring-boot-starter -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.0</version>
</dependency>
<dependency>

<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- JDBC-->

</dependency>
<!-- 导入页面依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency> -->
<!-- thymeleaf,都是基于3.x开发的-->

</dependency>
</dependencies>
<hr>
3、配置文件.properties
#整合mybatis
mybatis.type-aliases-package=com.zheng.pojo
mybatis.mapper-locations=classpath:mybatis/mapper/*.xml
<hr>
4、连接数据库的yml文件
thymeleaf:
prefix: classpath:/templates/ #prefix:指定模板所在的目录
check-template-location: true #check-tempate-location: 检查模板路径是否存在
cache: false #cache: 是否缓存,开发模式下设置为false,避免改了模板还要重启服务器,线上设置为true,可以提高性能。
suffix: .html
encoding: UTF-8
content-type: text/html
mode: HTML5
spring:
datasource:
username: root
password: root
url: jdbc:mysql://localhost:3306/managebook?allowMultiQueries=true&characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false
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的,需要自己绑定
#druid 数据源专有配置
initiaSize: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsmMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false

poolPreparedStatements: true
filters: stat,wall,log4j
maxPoolPrepareStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
<hr>
5、实体类
==提示:建议使用Lombok==
package com.zheng.pojo;
public class User {
private String name;
private String password;
private String perm;
public User() {
}
public User(String name, String password, String perm) {
this.name = name;
this.password = password;
this.perm = perm;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPerm() {
return perm;
}
public void setPerm(String perm) {
this.perm = perm;
}
}
<hr>
6、controller层
package com.zheng.controller;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class UserController {
@RequestMapping("/toLogin")
public String index(){
return "login";
}
//跳转到未授权界面
@RequestMapping("/ungrant")
public String ungrant(){
return "ungrant";
}
//跳转到怎加
@RequestMapping("/admin/add")
public String addpPage(){
return "add";
}
@RequestMapping("/admin/update")
public String updatePage(){
return "update";
}
@RequestMapping("/index")
public String toIndex(){
return "index";
}
@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);
try {
subject.login(token);//执行登陆的方法,如果没有异常则是正确的
return "index";//进入个人信息界面
} catch (UnknownAccountException e) {
model.addAttribute("msg","用户名错误");
return "login";
}catch (IncorrectCredentialsException e){
model.addAttribute("msg","密码不存在");
return "login";
}
}
}
<hr>
7、service层
package com.zheng.service;
import com.zheng.pojo.User;
public interface UserService {
//查询用户信息
User login(String name);
}
<hr>
8、serviceImpl层
package com.zheng.service.impl;
import com.zheng.mapper.UserMapper;
import com.zheng.pojo.User;
import com.zheng.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserServiceImpl implements UserService {
@Autowired
UserMapper userMapper;
@Override
public User login(String name) {
return userMapper.login(name);
}
}
<hr>
9、mapper层
package com.zheng.mapper;
import com.zheng.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
@Mapper //这个注解表示这个是mybatis的mapeper
@Repository
public interface UserMapper {
//查询用户信息
User login(String name);
}
<hr>
10、mapper文件层(编写SQL语句)
<?xml version="1.0" encoding="UTF8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zheng.mapper.UserMapper">
<!--查询某一个用户的信息-->
<select resultType="com.zheng.pojo.User" >
select * from user where name=#{name}
</select>
</mapper>
11、前端页面简单的表示(这里制作简单的演示、前端框架也很多)
11.1、index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>首页</title>
</head>
<body>
<a rel="nofollow" th:href="@{/admin/add}">add</a> <a rel="nofollow" th:href="@{/admin/update}">update</a>
</body>
</html>
11.2、login.htm
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>登录</title>
</head>
<body>
<form th:action="@{/login}" >
用户名:<input type="text" name="username" placeholder="请输入姓名" ><br>
密码:<input type="text" name="password" placeholder="请输入密码"> <br>
<button type="submit" >登录</button>
</form>
</body>
</html>
11.3、ungrant.html未授权页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>未授权页面</title>
</head>
<body>
未授权页面
</body>
</html>
11.4、add.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>增加页面</title>
</head>
<body>
add
</body>
</html>
11.5、update.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>修改页面</title>
</head>
<body>
update
</body>
</html>
<hr>
12、实际效果展示
12.1、第一种情况、还未登录直接访问首页中的链接
<hr>
12.2、第二种情况、登录后访问首页中的链接
首先看一下数据库中数据、更加具有说服力
在首页中测试add 在首页中测试update <hr>
13、解析说明 、过滤器的代码
package com.zheng.config;
import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.LinkedHashMap;
import java.util.Map;
@Configuration
public class ShiroConfig {
//ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securitymanager") DefaultWebSecurityManager defaultWebSecurityManager) {
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
//设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
//添加shiro的内置过滤器
/**
* anon:无需认证就可访问 * authc:必须认证才能访问* 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能访问* role:拥有某个角色权限才能访问
*/
Map<String, String> filterMap = new LinkedHashMap<>();
//授权,正常的情况下,没有授权会跳转到未授权页面
// filterMap.put("/admin/*","authc");//admin请求下的都需要认证
filterMap.put("/admin/add", "perms[user:add]");
filterMap.put("/admin/update", "perms[user:update]");
bean.setFilterChainDefinitionMap(filterMap);
//如果没有认证、设置登录的请求
bean.setLoginUrl("/toLogin");
//如果没有授权,跳转到未收取页面
bean.setUnauthorizedUrl("/ungrant");
return bean;
}
//DefaultWebSecurityManager
@Bean(name = "securitymanager")
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm) {
DefaultWebSecurityManager securitymanager = new DefaultWebSecurityManager();
//关联UserRealm
securitymanager.setRealm(userRealm);
return securitymanager;
}
//创建realm对象,需要自定义安装
@Bean
public UserRealm userRealm() {
return new UserRealm();
}
//整合ShiroDialect:用来整合shiro thymeleaf
@Bean
public ShiroDialect getShiroDialect() {
return new ShiroDialect();
}
}
<hr>
14、授权和认证
package com.zheng.config;
import com.zheng.pojo.User;
import com.zheng.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
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 org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.Collection;
import java.util.HashSet;
import java.util.Set;
//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");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// info.addStringPermission("user:update");
//拿到当前的登录对象
Subject subject = SecurityUtils.getSubject();
User user = (User)subject.getPrincipal();
//设置当前用户的权限
info.addStringPermission(user.getPerm());
return info;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// 第一种方式
// 获取用户输入的账号和密码(一般只需要获取账号就可以)
System.out.println("执行了认证");
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
//连接真实的数据库
User user = userService.login(userToken.getUsername());
//1、思路:在用户表中新增加一个权限字段、然后再次查询数据库获得该用户所具有的权限(该权限为要给集合??????
if(user == null){
//没有这个人
return null;
}
//密码认证
return new SimpleAuthenticationInfo(user,user.getPassword(),"");
}
}
15、关键解说:
整理不易、老板、给个赞吧!!!这样白嫖的稍稍心安一点、哈哈哈哈哈哈
