Emir's answer is great and it describes the problem that you are getting. However I suggest you to try spring-retry.

It's a brilliant framework that implements the retry pattern via annotation(s).

Example:

 @Retryable(maxAttempts = 4, backoff = @Backoff(delay = 500))
 public void doSomethingWithMysql() {
   consumerTransactionTemplate.execute(
             new TransactionCallbackWithoutResult(){
                @Override
                protected void doInTransactionWithoutResult(                 
                      TransactionStatus status)
                {
                    process();
                }

            });
 } 

In case of exception, it will retry (call) up to 4 times the method doSomethingWithMysql() with a backoff policy of 500ms
