mybatis一對一查詢，字段重複解決辦法

一、sq語句中增加別名解決

 <sql id="selectVoteResultVo">
        select v.id,v.a,v.b,v.c,v.d,v.e,v.f,v.g,v.h,v.i,v.j,v.qrcode_key,v.number,v.votedcount,v.alive,v.time,
            w.a as aa,w.b as bb,w.c as cc,w.d as dd,w.e as ee,w.f as ff,w.g as gg,w.h as hh,w.i as ii,w.j as jj,w.theme,w.deviceName from votebean v
             left join word w on v.qrcode_key=w.qrcode_key
    </sql>

 二、resultMap中使用別名

 <resultMap id="Result1" type="Bean">
        <result property="id" column="id"/>
        <result property="a" column="a"/>
        <result property="b" column="b"/>
        <result property="c" column="c"/>
        <result property="d" column="d"/>
        <result property="e" column="e"/>
        <result property="f" column="f"/>
        <result property="g" column="g"/>
        <result property="h" column="h"/>
        <result property="i" column="i"/>
        <result property="j" column="j"/>
        <association property="word" resultMap="Result2"/>
    </resultMap>
    <resultMap id="Result2" type="Word">
        <result property="a" column="aa" javaType="String"/>
        <result property="b" column="bb" javaType="String"/>
        <result property="c" column="cc" javaType="String"/>
        <result property="d" column="dd" javaType="String"/>
        <result property="e" column="ee" javaType="String"/>
        <result property="f" column="ff" javaType="String"/>
        <result property="g" column="gg" javaType="String"/>
        <result property="h" column="hh" javaType="String"/>
        <result property="i" column="ii" javaType="String"/>
        <result property="j" column="jj" javaType="String"/>
    </resultMap>

 

      MyBatis 多表聯合查詢，兩張表中字段重複時，在配置文件中，sql語句聯合查詢時使用字段別名，resultMap中對應的column屬性使用相應的別名
