Mybatis-Oralce批量插入方法

mybatis-Oralce 中批量插入方法一：
<insert id="insertBatchSelective" parameterType="java.util.List" >
    insert into tbl_epcc_txn (TXN_CD, EPCC_TXN_ID, TXN_DATE)
    values
     <foreach item="item" collection="list" separator="," >
    (#{item.txnCd,jdbcType=VARCHAR}, #{item.epccTxnId,jdbcType=CHAR}, #{item.txnDate,jdbcType=CHAR})
      </foreach>
  </insert>

mybatis-Oracle 中批量插入方法二：
  <insert id="insertBatchSelective" parameterType="java.util.List" useGeneratedKeys="false">
         INSERT ALL
         <foreach item="item" index="index" collection="list">
		 INTO tbl_epcc_txn
		    <trim prefix="(" suffix=")" suffixOverrides="," >
			  TXN_CD, EPCC_TXN_ID, TXN_DATE,
		</trim>
	    <trim prefix="values (" suffix=")" suffixOverrides="," >
			  #{item.txnCd,jdbcType=VARCHAR}, #{item.epccTxnId,jdbcType=CHAR}, #{item.txnDate,jdbcType=CHAR},
	    </trim>
    </foreach>
          SELECT 1 FROM DUAL
     </insert>

测试sql：

  insert all
 into tbl_epcc_txn(EPCC_TXN_ID,TXN_CD) values('1','2017102410340796013842761770101')
 into tbl_epcc_txn(EPCC_TXN_ID,TXN_CD) values('2','2017102410340796013842761770101')
 into tbl_epcc_txn(EPCC_TXN_ID,TXN_CD) values('3','2017102410340796013842761770103')
 select 1 from dual;
