【mybatis】mybatis進行批量更新，報錯：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進行批量更新操作：

報錯如下：

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

 

但是檢查了以后，28行並沒有錯誤

使用【https://www.cnblogs.com/sxdcgaq8080/p/9100178.html】 打印了sql，發現sql如下，也沒有問題：

報錯原因：

是因為spring boot配置文件中，關於數據庫的連接配置，並沒有允許進行批量更新的操作

 

 

 

解決方法：

將數據庫配置修改為 
jdbc.url=jdbc:mysql://127.0.0.1:3306/datebase?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&allowMultiQueries=true

新增了 &allowMultiQueries=true 意為 允許批量更新

 

 

需要注意的是：

加了&allowMultiQueries=true 意為 允許批量更新

但是此時如果再想在spring boot中運行mybatis的時候想打印出來sql，就已經不起作用了。

此時按照
https://www.cnblogs.com/sxdcgaq8080/p/9100178.html
配置的，在spring boot中打印sql語句，就無效了
