MyBatis Batch Update Exception使用foreach批量update出错

#1 问题描述# 经过MyBatis框架,对Mysql数据库作批量更新,对于的Mapper.xml配置:java

<update id="updateTestcaseNodeBatch" parameterType="List">  
  <foreach collection="list" item="nodeVO" separator=";">  
    UPDATE testcase_node  
     <set>  
       name=#{nodeVO.name},  
       version=#{nodeVO.version},  
       description=#{nodeVO.description},  
       last_modify_user=#{nodeVO.createUser},  
       last_modify_time=#{nodeVO.createTime}  
     </set>  
     <where>  
       object_id=#{nodeVO.objectId} AND root_id=#{nodeVO.rootId}  
     </where>  
  </foreach>  
</update>

#2 排除过程#mysql

  1. 仔细检查 map文件 和数据库表字段没有错误;【正常】
  2. 将生产的SQL,贴到Mysql Client端执行;【正常】
  3. 再次检查JDBC驱动连接URL;【不正常】

#3 解决问题# 最终结果是由于配置的 mysql jdbc连接字符串 默认不支持一次性执行多个sql语句;可是在咱们的 update map中须要执行多个 update语句。最后加上参数 "allowMultiQueries" 设置为true 以下:spring

<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf-8&amp;allowMultiQueries=true" />

#4 总结问题# 问题解决!关键是解决问题的思路,由易到难,有外到内,确保最基本的配置不出问题。sql
