#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>
异常信息:node
### The error may involve com.hirain.testmanagement.mapper.TestcaseNodeMapper.updateTestcaseNodeBatch-Inline ### The error occurred while setting parameters ### SQL: UPDATE testcase_node SET name=?, version=?, description=?, last_modify_user=?, last_modify_time=?

#2 排除过程#mysql
#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&characterEncoding=utf-8&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
