GoodsMapper.java

package s.t.m.dao;

import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Repository;

import s.t.m.domain.Goods;

public interface GoodsMapper {
List<Goods> selectGoods();
int saveGoods(Map<String,Object> map);
}

GoodsMapper.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="s.t.m.dao.GoodsMapper">
<!-- 因为配置了typeAliasesPackage 可以不用写全路径s.s.m.domain.Goods -->
<select id="selectGoods" resultType="Goods">
SELECT goods_id as 'goodsId',goods_name as 'goodsName' FROM goods_back;
</select>

<insert id="saveGoods" parameterType="java.util.Map">
insert into goods_back(goods_name) values(#{goodsName})
</insert>
</mapper>

SpringBoot启动类

package s.t.m.main;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@EnableAutoConfiguration
//@ComponentScan(basePackages={"s.t.m.controller","s.t.m.service","s.t.m.dao","s.t.m.interceptor"})
//@ComponentScan(basePackages={"s.t.m.controller","s.t.m.service","s.t.m.dao","s.t.m.startup"})
@ComponentScan(basePackages={"s.t.m.controller","s.t.m.service"})
//@ServletComponentScan(basePackages={"s.t.m.filter","s.t.m.servlet"}) //过滤器、Servlet
//@ServletComponentScan(basePackages={"s.t.m.interceptor"})
@MapperScan("s.t.m.dao")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

此时完成整合，可以把Mapper注入到Service进行开发了。。。
