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;
