MySQL:存储过程可以调用Java程序吗? [英] MySQL: Can a stored procedure invoke a Java program?

问题描述

我有一个MySQL存储过程.我想让一个存储过程运行一些语句，然后调用一个Java程序.然后，当Java程序完成时，存储过程应完成.

I have a MySQL stored procedure. I would like to have a stored procedure run some statements, then call a Java program. Then when the java program is complete, the stored procedure should finish.

java程序将连接到数据库，进行一些分析，然后将行插入到其他表中.

The java program will connect to the database, do some analysis and then insert rows into other tables.

这可能吗?

推荐答案

是.看一下 MySQL UDF存储库和sys_exec函数.您可以使用它在新的JVM中启动Java代码.

Yes. Take a look at The MySQL UDF Repository and the sys_exec function. You could use this to launch your Java code in a new JVM.

安装后，将按照以下方式运行它: https://dba.stackexchange.com/a/39547/14506
