resultMap是取上面的resultMap封装好的数据表字段，resultType能直接写在domain和dto写的自己构造的Bean， resultMap里写的应该是上面resultMap里的id值，resultType里写的是自己构造Bean的路径位置。下面是代码：

<?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.edi.mapper.WsShipmentMapper">
