Springboot怎么快速集成Mybatis和thymeleaf？
前言
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。
目标
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。
环境配置
jdk版本:1.8
开发工具：Intellij iDEA 2020.1
springboot:2.3.9.RELEASE
具体步骤
依赖引入
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
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=false
spring.thymeleaf.suffix=.html
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.encoding=utf-8
#数据库连接配置
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3307/happy_home?serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root
#mybatis配置
mybatis.mapper-locations=classpath:/mapper/*.xml
mybatis.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>
后端代码
1、PersonController.java
@Controller
@RequestMapping("/person")
public class PersonController {@Autowiredprivate 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}")@ResponseBodypublic Person getPerson(@PathVariable("id") Integer id) {Person person = this.personService.get(id);return person;}
}2、IPersonService.java
public interface IPersonService {Integer registe(Person person);Person get(Integer id);
}3、PersonServiceImpl.java
@Service
public class PersonServiceImpl implements IPersonService {@Autowiredprivate PersonDao personDao;@Overridepublic Integer registe(Person person) {this.personDao.insert(person);return person.getId();}@Overridepublic Person get(Integer id) {Person person=personDao.selectById(id);return person;}
}4、PersonDao.java
@Mapper
public interface PersonDao {Integer insert(Person person);Person selectById(Integer id);
}5、PersonMapper.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.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_personwhere id = #{id}</select>
</mapper>6、Person.java
@Slf4j
@Data
public 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;
}
