After the service returns the response, it also needs to execute the code how to handle, Servle, controller in advance response

Requirements: Build Ping++webhoks push interface, their push 5, 6 seconds will time out, if my service interface does not give him to return 200, he will cut off time to push, because the interface needs to deal with more business, it is easy to time out, so need to judge the data port of Push, Return the response directly to him before doing business processing.

Solution: PrintWriter out = Response.getwriter ();

Out.close ();//return the response in advance, continue execution later, or time out

Then execute the business code
