SpringBoot整合Mybatis(xml方式)

一.在上一篇博客我简单记录了SpringBoot整合Mybatis（注解方式）

https://blog.csdn.net/u012430402/article/details/80185366

以下记录依赖于上一篇博客的工程

二.工程目录如下：

三.在pom.xml中引入Druid依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.0.5</version>
</dependency>

四.在application.yml中设置使用Druid数据源和Mapper映射文件的路径

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/demo?characterEncoding=utf-8
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource

mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.xiao.pojo

五.书写映射文件UserMapper.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.xiao.mapper.UserMapper">

 	<!-- 根据id查询用户  -->
 	<select id="getUser" parameterType="Integer" resultType="User">
		select * from tb_user where id = #{id}
	</select>
	
 </mapper>

六.启动项目，访问地址http://localhost:8080/getUser?id=1

成功！
