如何在没有运行mySQL服务器的情况下从JDBC调用记录SQL语句？

Question

So, I'm trying to figure out how to log the SQL statements that would be run, without actually having an active mySQL server.

The problem I'm trying to solve is right now we're writing data to both a remote mySQL instance, as well as a local (archive data). We're logging to a local as a backup in case the remote becomes unreachable/goes down/etc.

So, what we'd like to do instead is log the SQL statements locally (we're going through Spring JDBC Template w/variable replacement), so not quite as easy as taking the SQL we piece together ourselves and write it to a file.

I did find log4jdbc which looks great, except we'd still need a local mySQL instance active, even if it's just using the blackhole engine. I did think maybe we could just use the log4jdbc on the remote server, but if the connection goes away, will the JDBCTemplate even try and run the queries on the underlying JDBC driver objects before getting the failure? Most pooling mechanisms will validate the connection before returning it, so it'd still just fail before the query had a chance to run & get logged.

So, who has any bright ideas?

Answer 1

Run the remote MySQL instance with bin logging enabled .

The binary logs can be backed up and if necessary converted into SQL using the mysqlbinlog command, to later restore a database.

一般而言，Mark O'Connors解决方案可能是最好的解决方案，但是我们解决此问题的方法是将数据简单地写为CSV文件格式，以便可以通过加载数据infile语句导入。
