如何用MyBatis一次性执行多条更新操作?

在mapper文件的一个更新节点中,执行多条update语句的操作如下:

xmlupdate id=cleanUserByPhone parameterType=java.lang.Stringuserset valid_status=1where mobile_phone=#{mobilePhone}

想在mapper的一个更新节点进行多条update语句的操作:

<update id="cleanUserByPhone" parameterType="java.lang.String"> update user set valid_status = 1 where mobile_phone = #{mobilePhone}; update user_account set valid_status = 1 where mobile_phone = #{mobilePhone} ; </update>

mybatis是默认不支持的,需要在数据库配置中配置相关参数:

propertes 或者yml配置 文件中的jdbc后追加&allowMultiQueries=true

jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/database?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true

补充:mybatis批量更新update-设置多个字段值

mybatis由于简单易用性得到大家的认可和使用

但是在批量更新操作中,网上介绍的貌似不全,正好今天做个记录,大家一起进步

在实际项目开发过程中,常有这样的需求:根据ids更新表的某一个字段值,这时的sql语句是:

public interface IStaffDao { void batchUpdate(@Param("list") List<Long> list); }

<select id="getStaffsByIds" resultMap="staff_Mapper"> update staff set status = 0 where id in <foreach collection="list" item="item" index="index" open="(" separator="," close=")" > #{item} </foreach> ORDER BY id </select>

还有一种情况:根据ids更新表的多个值,并且每个id对应的值也不一样,这时上述语句已经满足不了需求,需要另一种批量更新sql语句

public interface IStaffDao { void batchUpdate(@Param("list") List<Staff> list); }

<update id="batchUpdate" parameterType="java.util.List" > <foreach collection="list" item="item" index="index" separator=";"> UPDATE staff set count = #{item.count} , code = #{item.code} , invalid_time = #{item.time} WHERE id = #{item.id} </foreach> </update>

由于这种批量更新是一次执行多个update语句,所以mybatis需要额外的配置:

spring.datasource.url后加上allowMultiQueries=true

如:jdbc:mysql://10.10.20.36:3306/test?allowMultiQueries=true

否则,在执行sql语句时,会报下面的错误

[org.apache.ibatis.session.defaults.DefaultSqlSession@76a2f910] org.springframework.jdbc.BadSqlGrammarException: ### Error updating database.

以上为个人经验,希望能给大家一个参考,也希望大家多多支持易盾网络。如有错误或未考虑完全的地方,望不吝赐教。
