This is a question I have for a long time. For a db access method, normally we have the structure of:

Is there a way to clean up th code for the last catch block which is for the db clean up exception? Or do I have to write such block in each db call?

If the "db cleanup" is the same, put all that finally stuff in a static class.

A common approach is to create a DBUtils class that has the common code in a static method. Then you can pass the connection/statement/resultset into that method. So one call is repeated instead of a bunch of code.

Another common solution to avoid writing the same dull jdbc code over and over is to use Spring JDBC, a part of the Spring framework. It neatly encapsulates all of the plumbing (connection management, exception handling, looping through result sets, resource cleanup etc.) and lets you focus on the important stuff.

Admit nothing. Blame everyone. Be bitter.
I agree. Here's the link:
