springboot集成mybatis的两种方式：

相对于传统的SSM框架，springboot+mybatis的方式更加轻便，那么如何快速集成二者进入开发呢？

1. mapper接口+xml
   mapper接口：
   

   public interface PaymentMapper {
       public PayRecord select(@Param("orderNo")String orderNo);
   }

   xml文件：
   

   <?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.xp.pay.gateway.mapper.PaymentMapper">
       <select id="select"  parameterType="string" resultType="com.xp.pay.gateway.entity.PayRecord">
           select * from tbs_pay_record where order_no = #{orderNo} limit 1
       </select>
   </mapper>

   application.yml

   mybatis :
     type-aliases-package : com.xp.pay.gateway.*
     mapperLocations: classpath:mapper/*.xml
   

2. mapper接口+注解
   mapper接口：
   

   @Mapper
   @Repository
   public interface PaymentMapper {
       @Select("select * from tbs_pay_record where order_no = #{orderNo} ")
       public PayRecord selectByOrderNo(String orderNo);
   }
   

   application.yml：

   mybatis :
     type-aliases-package : com.xp.pay.gateway.*
