Creating custom REST request handlers

We can create custom REST request handlers to communicate with the REST post-processing system. A template is provided that we can adapt for our own purposes.

Procedure

1. Create a new request handler that implements the RequestHandler call with RequestHandlerAnnotation defined.

   handleRequest(MessageContext, HandlersChain) method
   @RequestHandlerAnnotation(
   sequence="200"
   public class CustomRequestHandler implements RequestHandler {
       @Override
       public void handleRequest(MessageContext messageContext,
                         HandlersChain handlersChain) {
                          // Add our own logic here       
   
                         handlersChain.doChain(messageContext);
                         // Add our own logic here
       }
   }

   Where

   sequence

   Defines the registered order in which the request handler will be executed. Permitted values range from 0 to 2147483647. Default is 100. If two sequences are the same in a customized request handler, only the one loaded last will take effect.

2. Restart the server and test your REST request handler.
