一.创建项目
将STS与eclipse集成，新建SpringBoot项目，勾选如下选项
一路next，pom.xml文件会帮我们配置好.
但我们还需要引入thymeleaf模板引擎，需要我们手动向pom.xml文件中添加
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
数据源我们引用阿里的druid,需要我们向pom.xml文件中手动添加
<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.21</version>
</dependency>
完整的pom.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
接下来需要在application.properties 中指定数据库连接信息与数据源
spring.datasource.username=root
spring.datasource.password=20182022
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/my?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=GMT%2B8
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
二 .创建数据表
表结构:
相应的java bean
package com.example.demo.pojo;
public class Custom {
private String sname;
private String passwords;
private Integer age;
public Custom() {
super();
// TODO Auto-generated constructor stub
}
public Custom(String sname, String passwords, Integer age) {
super();
this.sname = sname;
this.passwords = passwords;
this.age = age;
}
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
public String getPasswords() {
return passwords;
}
public void setPasswords(String passwords) {
this.passwords = passwords;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "Custom [sname=" + sname + ", passwords=" + passwords + ", age=" + age + "]";
}
}
三 .书写mapper
在mappper包下新建CustomMapper.xml文件与CustomMapper.java接口
<?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.example.demo.mapper.CustomMapper">
<insert id="insert" parameterType="com.example.demo.pojo.Custom">
insert into custom(sname,passwords,age) values(#{sname},#{passwords},#{age})
</insert>
</mapper>
import com.example.demo.pojo.Custom;
public interface CustomMapper {
public void insert(Custom custom);
}
四.创建Service
在service包下新建CustomService.java接口与CustomServiceImpl.java实现类
package com.example.demo.mapper;
import com.example.demo.pojo.Custom;
public interface CustomMapper {
public void insert(Custom custom);
}
package com.example.demo.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.example.demo.mapper.CustomMapper;
import com.example.demo.pojo.Custom;
@Service
public class CustomServiceImpl implements CustomService{
@Autowired
private CustomMapper customMapper;
@Override
public void insertCustom(Custom custom) {
// TODO Auto-generated method stub
customMapper.insert(custom);
}
}
五.创建controller
