想在mapper的一个更新节点进行多条update语句的操作:
update user set valid_status = 1 where mobile_phone = #{mobilePhone};
update user_account set valid_status = 1 where mobile_phone = #{mobilePhone} ;
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: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 list);
}
update staff set status = 0 where id in
#{item}
ORDER BY id
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 list);
}
UPDATE staff set count = #{} , code = #{} , invalid_time = #{} WHERE id = #{}
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：
在后加上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
[.session.@76a2f910]
