1.创立一个springboot我的项目
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创立一个controller
package com.yao.controller; import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping; @Controllerpublic class MyController { @RequestMapping({"/","/index"}) public String toIndex(Model model){ model.addAttribute("msg","hello,Shiro"); return "index"; }}肯定要记住shiro的三大对象
1.subject：用户
2.SecurityManager：治理所有用户
3.Realm：连贯数据
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创立一个config(ShiroConfig)，并编写他
package com.yao.config; import org.springframework.context.annotation.Configuration; @Configurationpublic class ShiroConfig { //ShiroFilterFactoryBean //DefaultWebSecurityManager //创立 realm 对象，这个realm对象须要自定义 }1.5创立本人的一个realmconfig，也就是在config中创立另外一个配置类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 UserRealmpublic class UserRealm extends AuthorizingRealm { //受权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("受权。。。"); 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外面去，是咱们本人写的这个类被spring托管
1.7新建两个测试页面并从新写一下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="@{/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; @Controllerpublic 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增加过滤器
还是在shiroconfig中退出：
//增加Shiro的内置过滤器/* anon：无需认证就能够拜访 authc：必须认证了能力通过 user：必须领有记住我性能能力用 perms：领有对某个资源的权限才能够拜访 role：领有某个角色权限能力拜访 */Map<String,String> filterMap = new LinkedHashMap<>();// filterMap.put("/user/add","authc");// filterMap.put("/user/update","authc");filterMap.put("/user/*","authc");bean.setFilterChainDefinitionMap(filterMap);//设置登录的申请bean.setLoginUrl("/toLogin");return bean;这里心愿没有认证就从add和update跳到login页面因而还要写一个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>明码：<input type="text" name="password"></p> <p><input type="submit"></p></form></body></html>1.10下面曾经实现了页面拦挡的性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>明码：<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){//获取以后用户Subject subject = SecurityUtils.getSubject();//封装用户的登录数据(令牌),这里是存在全局外面，都能够调的到UsernamePasswordToken token = new UsernamePasswordToken(username, password);try {subject.login(token);// 执行登陆的办法，如果没有异样就ok了return "index"; } catch (UnknownAccountException e) {model.addAttribute("msg","用户名谬误");return "login"; } catch (IncorrectCredentialsException e){model.addAttribute("msg"," 明码谬误");return "login"; }}UserRealm:
//认证@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("认证。。。"); //用户名，明码 数据库中取String name = "root";String password = "123456"; UsernamePasswordToken userToken = (UsernamePasswordToken) token; if(!userToken.getUsername().equals(name)){return null;//它这里会主动抛出后面的用户名谬误的异样}//明码认证不让你做，它本人做，他不让你接触明码return new SimpleAuthenticationInfo("",password,""); }}间接测试即可发现以上性能根本实现。
package com.yao.controller; import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping; @Controllerpublic 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

application.properties
mybatis.type-aliases-package=com.yao.pojomybatis.mapper-locations=classpath:mapper/*.xml2.4创立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@NoArgsConstructorpublic class User { private int id; private String name; private String pwd;}2.4创立mapper层，并写出绝对应的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@Mapperpublic 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.javapackage 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; @Servicepublic 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; @SpringBootTestclass ShiroSpringbootApplicationTests { @Autowired UserServiceImpl userService; @Test void contextLoads() { System.out.println(userService.queryUserByName("幺幺")); } }测试胜利，持续写
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 UserRealmpublic class UserRealm extends AuthorizingRealm { @Autowired UserService userService; //受权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("受权。。。"); return null; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("认证。。。"); UsernamePasswordToken userToken = (UsernamePasswordToken) token; //连贯实在数据库 User user = userService.queryUserByName(userToken.getUsername()); if (user==null){ return null; } //明码认证不让你做，它本人做，他不让你接触明码 return new SimpleAuthenticationInfo("",user.getPwd(),""); }}2.8增加明码加密
//还有一个md5加密，集成了hashcode是不可逆的 //比方你的明码是123456// md5(123456,32) = e10adc3949ba59abbe56e057f20f883e// md5(123456,16) = 49ba59abbe56e057 //MD5盐值加密e10adc3949ba59abbe56e057f20f883eusername //明码认证不让你做，它本人做，他不让你接触明码 return new SimpleAuthenticationInfo("",user.getPwd(),"");2.9申请受权实现
==============
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@Mapperpublic interface UserMapper {public User queryUserByName(String name);}举荐浏览
