Spring Jms ActiveMq – How to send Java object messages to ActiveMQ server (specially with Bi-Directional relationship Java objects)

The previous Spring ActiveMQ tutorials, We had learned How to produce and consume JMS messages with String format and configure Explicity ActiveMq ConnectionFactory. But How to send Java object messages to ActiveMQ server? With the tutorial, JavaSampleApproach will show you how to produce/consume Java object messages with Spring JMS ActiveMq for both case: normal Java objects and complex Java objects with Bi-directional relationship.

ActiveMq – Explicitly configure Spring ActiveMq ConnectionFactory with SpringBoot

In the past tutorial, we had learned how to start a Spring JMS ActiveMQ application with auto-configured ConnectionFactory by SpringBoot.
But in the software development, there’re many cases that we need to override the ContainerFactory, so How to do it? JavaSampleApproach makes the tutorial to guide how to explicitly configure Spring ActiveMQ ConnectionFactory.

WebSocket – Create Spring WebSocket Application with SpringBoot + SockJS + STOMP

The WebSocket protocol provides new capability for web applications: full-duplex, two-way communication. So in the system where the client and server need to exchange data at high frequency and with low latency, WebSocket is the best solution. That is the reason for us to create a Spring WebSocket Application with JavaSampleApproach.

Reactor – Simple Ways to create Flux/Mono

Reactive Streams is an API and pattern that provides a standard for asynchronous stream processing with non-blocking back pressure. It is also being introduced in Java 9 Flow API with four simple interfaces: Publisher, Subscriber, Subscription and Processor.

But Reactive Streams API is just low level to make practical use in reactive applications. So Reactor Core provides two main implementations of Publisher: Flux and Mono. In this tutorial, we’re gonna know what they are and simple ways to create them.

How to resolve Json Infinite Recursion problem when working with Jackson

Json Infinite Recursion is one of the most common problems when we serialize Java objects which having Bidirectional-Relationships. So in the tutorial JavaSampleApproach will guide you how to smoothly handle the problems with Jackson annotations: @JsonIgnore, @JsonView, {@JsonManagedReference, @JsonBackReference} and @JsonIdentityInfo.
