【mybatis】mybatis进行批量更新,报错:com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right

使用mybatis进行批量更新操作:

报错如下:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'update
                goods g
            SET
                update_date = '2019-03-19 17:16:05.918',
                updat' at line 28

 

但是检查了以后,28行并没有错误

使用【https://www.cnblogs.com/sxdcgaq8080/p/9100178.html】 打印了sql,发现sql如下,也没有问题:

报错原因:

是因为spring boot配置文件中,关于数据库的连接配置,并没有允许进行批量更新的操作

 

 

 

解决方法:

将数据库配置修改为 
jdbc.url=jdbc:mysql://127.0.0.1:3306/datebase?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&allowMultiQueries=true 新增了 &allowMultiQueries=true 意为 允许批量更新

 

 

需要注意的是:

加了&allowMultiQueries=true 意为 允许批量更新

但是此时如果再想在spring boot中运行mybatis的时候想打印出来sql,就已经不起作用了。

此时按照
https://www.cnblogs.com/sxdcgaq8080/p/9100178.html
配置的,在spring boot中打印sql语句,就无效了
