MyBatis兩張表字段名相同產生的問題

結論： 通過設置別名的方式讓其產生區別

<select id="queryBySekillId" resultMap="successKilled">

		select 
			sk.seckill_id  "seckill_id",
			sk.user_phone  "user_phone",
			sk.state  "state",
			sk.create_time  "create_time",
			s.seckill_id  "seckill_id",
			s.name  "name",
			s.number  "number",
			s.start_time  "start_time",
			s.end_time  "end_time",
			s.create_time  "screate_time"
		from success_killed sk
		inner join seckill s
		on sk.seckill_id = s.seckill_id
		where sk.seckill_id = #{seckill_id} ;

</select>

以上 success_killed表和seckill表中有相同字段 create_time （id字段其實確實是相同的故在此忽略），通過將表seckill的create_time字段命名為screate_time用以區別。

<resultMap type="Seckill" id="seckill">
		<id column="seckill_id"  property="seckill_id"/>
		<result column="name" property="name"/>
		<result column="number" property="number"/>
		<result column="start_time" property="start_time" />
		<result column="end_time"  property="end_time"/>
		<result column="screate_time"  property="create_time" />	
</resultMap>
	

同時將 resultMap中該段的 column 屬性該為 screate_time.故只要讓查詢出的字段名與column相同，它會通過映射找到相應屬性進行封裝。
