#1 問題描述# 經過MyBatis框架,對Mysql數據庫作批量更新,對於的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>
異常信息:node

#2 排除過程#mysql
#3 解決問題# 最終結果是由於配置的 mysql jdbc連接字符串 默認不支持一次性執行多個sql語句
;可是在咱們的 update map中須要執行多個 update語句。最後加上參數 "allowMultiQueries" 設置爲true 以下:spring
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true" />
#4 總結問題# 問題解決!關鍵是解決問題的思路,由易到難,有外到內,確保最基本的配置不出問題。sql
