mysql - 记录jdbc执行的mysql语句

Question

我尝试记录由 jdbc 执行的 mysql 语句，希望看到包含声明一些游标 或获取一些游标 的字符串。但是没有。有什么方法可以看到它们吗？PS 我在 mysql 中设置变量如下:

SET GLOBAL log_output="FILE"
SET GLOBAL general_log_file="Path/File"
SET GLOBAL general_log='ON'

试试这个。

将 'logger' 和 'profileSQL' 添加到 jdbc url:

&logger=com.mysql.jdbc.log.Slf4JLogger&profileSQL=true

然后你会得到如下SQL语句:

默认记录器是:

com.mysql.jdbc.log.StandardLogger
