MyBatis Batch Update Exception 使用foreach 批量update 出错

源地址   http://quabr.com/22829539/mybatis-batch-update-exception

使用如下Mybatis  map xml文件 

  
    UPDATE testcase_node
     
       name=#{nodeVO.name},
       version=#{nodeVO.version},
       description=#{nodeVO.description},
       last_modify_user=#{nodeVO.createUser},
       last_modify_time=#{nodeVO.createTime}
     
     
       object_id=#{nodeVO.objectId} AND root_id=#{nodeVO.rootId}
     
  

出错信息：

仔细检查 map文件 和数据库表字段没有错误

最终结果是因为 配置的 mysql jdbc 链接字符串 默认不支持一次性执行多个sql 语句；

但是在我们的 update map中需要执行多个 update语句。

最后加上参数 "allowMultiQueries" 设置为true  如下：

&allowMultiQueries=true" />  

问题解决!
