Design pattern for “retrying” logic that failed?

Question

I\'m writing some reconnect logic to periodically attempt to establish a connection to a remote endpoint which went down. Essentially, the code looks like this:

Answer 1

You can try spring-retry, it has a clean interface and it's easy to use.

Example:

 @Retryable(maxAttempts = 4, backoff = @Backoff(delay = 500))
 public void establishConnection() {
    this.connection = newConnection();
 } 

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