1.新建maven項目
先新建一個maven項目，勾選上creat a simple project，填寫groupid，artifactid
2.建立項目結構
3.添加依賴

4.代碼編寫
在包的最外層添加啟動類

還有mapper.xml的實現

<?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.driverspring.datasource.url=jdbc:mysql://localhost:3306/test?useunicode=true&characterencoding=utf-8spring.datasource.username=rootspring.datasource.password=rootmybatis.mapper-locations: classpath:mapper/*.xml |
