springboot集成mybatis
1.按照“springboot连接mysql数据库”文章内容进行配置
2.以上配置成功后，pom.xml文件中添加新的依赖
<!-- mybatis-spring-boot-starter -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>3.在程序主入口Application.java中添加注解@MapperScan("com.szcatic.dao")，扫描DAO数据接口
4.在application.properties文件中添加mybatis映射文件扫描路径
mybatis.mapper-locations=classpath:mapper/*.xml5.编写数据接口类UserDao.java
package com.szcatic.dao;
import java.util.List;
import com.szcatic.entity.User;
public interface UserDao {
List<User> findUsers();
}
6.在配置的映射文件路径下建立映射文件userDao.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.szcatic.dao.UserDao">
<sql id="userColumns">
f_username AS 'userName',
f_password AS 'password'
</sql>
<select id="findUsers" resultType="com.szcatic.entity.User">
SELECT
<include refid="userColumns"/>
FROM t_user
</select>
</mapper>7.编写测试类UserDaoTest.java
package com.szcatic.test;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import com.szcatic.Application;
import com.szcatic.dao.UserDao;
@Configuration
@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = Application.class)
public class UserDaoTest {
@Autowired
private UserDao UserDao;
@Test
void testUserDao() {
System.out.println(UserDao.findUsers());
}
}
8.运行测试方法testUserDao()，控制台输出结果如下
