Introduction The example I will show you here about the asynchronous communication among microservices or how microservices communicate asynchronously among themselves. A microservices-based application is a distributed system running on multiple processes or services, usually even across multiple servers or hosts. Each service instance is typically a process. Therefore, services must interact using an inter-process…

Introduction I am going to discuss here how to perform asynchronous request processing via Spring’s DeferredResult class. A DeferredResult can be used when the application wants to produce the return value from a thread of its own choice. A DeferredResult is what is possibly not-yet-finished computation that will be available in future. Spring MVC 3.2…

Introduction In this tutorial I will discuss about the asynchronous execution support in Spring using the @Async annotation. There are cases where Spring framework’s @Async is necessary to execute piece of code asynchronous. An example would be while sending a (JMS) message from one system to another system. The advantage is that the user does…

This tutorials will show you how we can concurrently execute different operations using Java utility class called java.util.concurrent.Executors in Spring framework. Spring supports XML as well as Programmatic configuration of beans but, here we will use XML based metadata configuration. If you already have an idea on how to create a maven project in Eclipse…

Introduction Here I am going to give an example on how Asynchronous REST webservice with Connection Callback. The most important concept in REST is resources, which are identified by global IDs — typically using URIs. Client applications use HTTP methods (GET/ POST/ PUT/ DELETE) to manipulate the resource or collection of resources. A RESTful Web…

Introduction Here I am going to give an example on how Asynchronous REST webservice with Completion Callback. The most important concept in REST is resources, which are identified by global IDs — typically using URIs. Client applications use HTTP methods (GET/ POST/ PUT/ DELETE) to manipulate the resource or collection of resources. A RESTful Web…

Introduction Here I am going to give an example Asynchronous REST service with Timeout using Jersey API. The most important concept in REST is resources, which are identified by global IDs — typically using URIs. Client applications use HTTP methods (GET/ POST/ PUT/ DELETE) to manipulate the resource or collection of resources. A RESTful Web…

I have taken Theoretical concepts from http://docs.oracle.com/javaee/1.3/jms/tutorial/1_3_1-fcs/doc/overview.html#1027335 with a little modifications. What Is Messaging ? Messaging is a method of communication between software components or applications. A messaging system is a peer-to-peer facility: A messaging client can send messages to, and receive messages from, any other client. Each client connects to a messaging agent that…
