最近在做一個會員營銷專案，其中有業務涉及到批量update問題，我用mybatic foreach實現批量update，但sql一直沒問題，但是偏偏報以下奇葩問題：

以下是xml的sql：
<update id="batchUpdatePackageIdByCouponsIds" parameterType="java.util.List"> <foreach collection="list" item="item" index="index" open="" close=";" separator=";"> update `am_counpons_details` <set>`cd_custId` = #{item.cdCustid,jdbcType=VARCHAR}</set> <where>`cd_detailId` = #{item.cdLoginmobile,jdbcType=VARCHAR}</where> <!-- ( SELECT ddid FROM ( SELECT cd_detailId as ddid FROM am_counpons_details WHERE cd_counponsId = #{item.cdCounponsid,jdbcType=VARCHAR} AND ISNULL( cd_gitPackageId ) LIMIT 0,1) tmps ) --> </foreach> </update>
百思不得其解，明明sql是navicat是可以執行的，上網找了下資料，看到一大神帖子，終於知道原因：
附上大神帖子：http://blog.csdn.net/mmm333zzz/article/details/45287309
用mybatic 批量更新必須加上引數&allowMultiQueries=true，如下
jdbc:mysql://192.168.68.23:3306/smi_am?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true；
這引數意思是允許多個查詢。
執行後弄log4j列印的日誌：
update `am_counpons_details` SET `cd_custId` = ? WHERE `cd_detailId` = ? ; update `am_counpons_details` SET `cd_custId` = ? WHERE `cd_detailId` = ? ;
