有时候做方案，需要模拟一些业务上的一些场景来验证方案的可行性，基本上每次都是到处百度如何集成springboot+mybatis+thymeleaf这些东西的集成平时基本上一年也用不了一次，虽然比较简单，奈何我真得记不住详细的每一步，因此每次都是从零开始，我一直在想，把时间浪费在这种重复的事情是没有意义的，所以这篇文章记录一下，以后再也不到处百度来接拼凑了。
springboot中集在mybatis和thymeleaf，简单实现一下新增和查询功能，后续有需要再往上补。

jdk版本:1.8
开发工具：Intellij iDEA 2020.1
springboot:2.3.9.RELEASE
主要引入了springboot、thymeleaf、mybais、mysql、jdbc以及热部署和lombda相关的依赖；
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</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><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency> <groupId>ognl</groupId> <artifactId>ognl</artifactId> <version>3.1.26</version></dependency><dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId></dependency><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional></dependency><dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.4</version></dependency><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId></dependency><dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId></dependency>配置文件这里新增了三处配置，分别是thymeleaf、数据库连接、mybatis;
#thymeleaf配置spring.thymeleaf.cache=falsespring.thymeleaf.suffix=.htmlspring.thymeleaf.prefix=classpath:/templates/spring.thymeleaf.servlet.content-type=text/htmlspring.thymeleaf.encoding=utf-8#数据库连接配置spring.datasource.driverClassName=com.mysql.cj.jdbc.Driverspring.datasource.url=jdbc:mysql://localhost:3307/happy_home?serverTimeznotallow=Asia/Shanghai spring.datasource.username=rootspring.datasource.password=root#mybatis配置mybatis.mapper-locatinotallow=classpath:/mapper/*.xmlmybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

前端代码
1、resources/static目录下，新增静态文件index.html;
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title></head><body><div id="testContent"> <form id="registeForm" name="registe" method="post" action="/person//registe" enctype="multipart/form-data" target="_self"> 登陆名：<input name="loginNo" type="text"/><br/> 姓名：<input name="userName" type="text"/><br/> 性别：<input name="sex" type="radio" value="男"/>男<input name="sex" type="radio" value="女"/>女<br/> 手机号码：<input name="phoneNumber" type="text"/><br/> 身份证号：<input name="IDCard" type="text"/><br/> 地址：<input name="address" type="text"/><br/> 门牌号：<input name="houseNumber" type="text"/><br/> <input type="submit" value="提交" id="submitForm"> </form></div></body></html>2、resources/templates目录上，新增home.html文件；
<!DOCTYPE html><html lang="en" xmlns:th="http://www.thymeleaf.org"><head> <meta charset="UTF-8"/> <title>主页</title> <script type="text/javascript" src="https://code.jquery.com/jquery-3.1.1.min.js"></script></head><body><div> ID:<span id="personId" data-th-text="${id}" ></span></div><div id="personInfo"> <p>登陆名:<span></span></p> <p>姓名:<span></span></p> <p>性别:<span></span></p> <p>手机号码:<span></span></p> <p>身份证号:<span></span></p> <p>地址:<span></span></p> <p>门牌号:<span></span></p></div></body><script type="text/javascript"> var id=$('#personId').text(); $.ajax({ url: 'http://localhost:8080/person/'+id, method: 'get', success: function (res) { console.log(res) $('#personInfo p')[0].append(res.loginNo); $('#personInfo p')[1].append(res.userName); $('#personInfo p')[2].append(res.sex); $('#personInfo p')[3].append(res.phoneNumber); $('#personInfo p')[4].append(res.idcard); $('#personInfo p')[5].append(res.address); $('#personInfo p')[6].append(res.houseNumber); } })</script></html>@Controller@RequestMapping("/person")public class PersonController { @Autowired private IPersonService personService; @PostMapping("/registe") public String registe(Person person, Model model) { Integer id = this.personService.registe(person); model.addAttribute("id", id); return "home"; } @GetMapping("/{id}") @ResponseBody public Person getPerson(@PathVariable("id") Integer id) { Person person = this.personService.get(id); return person; }}public interface IPersonService { Integer registe(Person person); Person get(Integer id);}@Servicepublic class PersonServiceImpl implements IPersonService { @Autowired private PersonDao personDao; @Override public Integer registe(Person person) { this.personDao.insert(person); return person.getId(); } @Override public Person get(Integer id) { Person persnotallow=personDao.selectById(id); return person; }}@Mapperpublic interface PersonDao { Integer insert(Person person); Person selectById(Integer id);}<?xml versinotallow="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.fanfu.dao.PersonDao"> <resultMap id="personMap" type="com.fanfu.entity.Person"> <result column="user_name" property="userName"></result> <result column="login_no" property="loginNo"></result> <result column="sex" property="sex"></result> <result column="phone_number" property="phoneNumber"></result> <result column="address" property="address"></result> <result column="house_number" property="houseNumber"></result> <result column="ID_card" property="IDCard"></result> <result column="id" property="id"></result> </resultMap> <insert id="insert" parameterType="com.fanfu.entity.Person" keyProperty="id" keyColumn="id" useGeneratedKeys="true"> insert into sys_person(user_name, login_no, phone_number, sex, ID_card, address, house_number) values (#{userName}, #{loginNo}, #{phoneNumber}, #{sex}, #{IDCard}, #{address}, #{houseNumber}) </insert> <select id="selectById" resultMap="personMap"> select * from sys_person where id = #{id} </select></mapper>@Slf4j@Datapublic class Person { private Integer id; private String userName; private String loginNo; private String phoneNumber; private String sex; private String IDCard; private String address; private String houseNumber;}本文链接：http://www.28at.com/showinfo-26-62357-0.htmlSpring Boot：如何快速集成Mybatis和Thymeleaf
