> I apologize for the lack of project experience, I am a student participant in Open Source Promotion Plan-Summer 2020. >_< OK, then I would recommend you to contact your mentor, and reading some materials about the usage of the connection pool. > Thank you, sir. I'm a little confused if connection is borrowed from pool, connection should not close twice when borrow connection from pool only once（forgive me. maybe my question is also beacuse I don't understand how the JDBC works） Writing the plugin means you have experience with the targeting library. You know how it works, and how you should use it. Your questions are around that part. Contact your mentor, and read more documents, real codes about the connection pool, you will know what is going on and should have a better design of the demo app to do the test. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
