4.代码编写

在包的最外层添加启动类

package com.lee.test;

@springbootapplication
@enablecaching
public class application {
  public static void main(string[] args) {
    springapplication.run(application.class, args);
  }
}

package com.lee.test.pojo;
 
import org.springframework.stereotype.component;
 
@component
public class user {
 
  private int id;
 
  private string name;
 
  private string telephone;
 
  public int getid() {
    return id;
  }
 
  public void setid(int id) {
    this.id = id;
  }
 
  public string getname() {
    return name;
  }
 
  public void setname(string name) {
    this.name = name;
  }
 
  public string gettelephone() {
    return telephone;
  }
 
  public void settelephone(string telephone) {
    this.telephone = telephone;
  }
 
}

mapper接口

package com.lee.test.mapper;
 
import java.util.list;
 
import org.apache.ibatis.annotations.mapper;
 
import com.lee.test.pojo.user;
 
@mapper
public interface usermapper {
 
  list<user> getuser(int id);
 
}

service接口

package com.lee.test.service;

public interface userservice {

}

}

controller层

package com.lee.test.controller;
 
import java.util.list;
 
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.web.bind.annotation.requestmapping;
import org.springframework.web.bind.annotation.requestparam;
import org.springframework.web.bind.annotation.restcontroller;
 
import com.lee.test.pojo.user;
import com.lee.test.service.userservice;
 
@restcontroller
public class usercontroller {
 
  @autowired
  private userservice userservice;
 
  @requestmapping("/getuser")
  public list<user> getuser(@requestparam("id") int id) {
    return userservice.getuser(id);
  }
 
}

还有mapper.xml的实现

<?xml version="1.0" encoding="utf-8"?>
<!doctype mapper public "-//mybatis.org//dtd mapper 3.0//en" "http://www.mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lee.test.mapper.usermapper">
  <select id="getuser" parametertype="java.lang.integer" resulttype="com.lee.test.pojo.user">
  select * from t_user where id = #{id}
  </select>
</mapper>

最后是一些配置在application.properties中

spring.datasource.driverclassname=com.mysql.jdbc.driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useunicode=true&characterencoding=utf-8
spring.datasource.username=root
spring.datasource.password=root
mybatis.mapper-locations: classpath:mapper/*.xml
