1. Basic concepts of JMS 1. JMS (Java Message Service) is a standard API used to access the enterprise message system. It facilitates message systems.Java applications in the system exchange messages, and simplify the development of enterprise applications by providing standard interfaces for generating, sending, and receiving messages.
2. Basic JMS FunctionsJMS
As it is, continue to improve the J2EE technical specifications. This time, we will write a JMS program. Understand the message-oriented middleware definition: Message
(1) message is a programmable mechanism for communication between two ends

TCP/IP sockets

File
Shared storage

Introduction to JMS
JMS (Java Message Service ). It is used to transmit messages between applications.
Enterprise Message
WebSphere MQ, SonicMQ, Microsoft Message Queue (MSMQ), ActiveMQ, Message Bean in EJB, and ESB (Enterprise Message Bus) in SOA are all Enterprise messages.
Enterprise Message can be used in the following ways:
Centralized
Distributed
Hybrid

Today, most computing environments are made up of different platforms rather than sticking to any platform. The Java Messaging Service (JMS), together with Extensible Markup Language (XML), satisfies the desire for this heterogeneous environment integration. This article demonstrates how to use JMS to create xml-based messages and distribute them equally to Java and non-Java applications.
After several yea

Brief introduction of Spring JMS and ACTIVEMQ 1.1 spring JMS and ACTIVEMQThe full name of JMS is the Java message Service, whose main purpose is to deliver the message between the producer and the consumer; in the actual business scenario, when a system completes a business operation, it needs to notify the state of the operation of system B or any other system a
Application As part of the Business Process Integration Strategy, the solution requires that different systems or components do not have to understand other systems or components integrated with them. Solutions include: Eliminates point-to-point communication and message transmission; Minimum dependence on the message data structure; Centralized management of business process flows; Publish/subscribe message transmission The J2EE Application Server architecture is an event-based applicati
1.ActiveMQ is an open source JMS implementation.Can not affect the user execution results and relatively time-consuming tasks (such as sending an email notification to the administrator) asynchronously thrown to the JMS server, and as soon as possible to return the screen to the user, and the server can be multithreaded queued to respond to high concurrent requests. Can achieve the highest decoupling in the
First, prefaceAfter mastering the structure of the message, let's look at one of the key features of JMS: the selector. Sometimes, as consumers only want to deal with the information they are interested in. If there is only one consumer of a message, we can allow the client to handle the messages that are of interest to them according to the rules, and those that do not satisfy certain rules are discarded directly.But if the message is the mechanism o
In this issue of J2EE pathfinder, Java developers and consultants Kyle Gabhart explained why message service is crucial to the enterprise's architecture, what types of obstacles must your solution overcome, as well as alternative solutions besides Java Message Service (JMS. At the end of this article, he analyzed three available solutions (Simple JMS Client), session beans used in combination with

After how camel used to retrieve files from and transfer files from ftp in a Project Integration Project last time, another application we often encounter in system integration is to transmit data to the queue of message-oriented middleware through JMS or retrieve messages from the queue of message-oriented middleware.

The recent need to design a distributed scheduled task, in theory, Quartz has provided a complete set of distributed scheduled tasks of the solution, but because the system currently has a JMS cluster and Redis Sentinel cluster, if you want to the existing architecture, Implementation of a simple distributed timing task, how to do it. The overall architecture plan is as follows:

In the previous article, I have already written about the PTP (point-to-point) mode of the JMS message mechanism. Today I will write about my personal publishing-subscription mode of the JMS message mechanism.
Before reading the text, I would like to explain the features and differences between PTP and publishing-subscription.
Features:
Point-to-Point message model: this model is implemented through a Serve

But it's a little long, and now I've forgotten what I said. Pay attention to the comments, which refer to the content of the article is wrong.
In spring, if there are both JMS operations and DB operations, there are probably three ways:

Recently, you want to learn about JMS and then learn about ACTIVEMQ, which is recorded here.1.ActiveMQ Introduction
ACTIVEMQ Official website: http://activemq.apache.org/
(The following excerpt from Baidu Encyclopedia)
ActiveMQ is the most popular, powerful, open source messaging bus that Apache has produced. ActiveMQ is a JMS provider implementation that fully supports the JMS1.1 and the Java EE 1.4 specif
Because the project is useful activemq, so record the learning process, first look at JMS.
The JMS (JAVA message Service,java messaging) API is a standard or specification of a messaging service that allows application components to create, send, receive, and read messages based on the Java EE platform. It makes distributed communication less coupled, and messaging services more reliable and asynchronous.

This will allow the JMS application to take advantage of Spring's transaction management features.

The cost of creating a connection from a WebSphere application Server to a Java message Service (JMS) provider, such as WebSphere MQ, is very high both in terms of time and processor requirements. To improve performance, WebSphere application Server maintains an idle connection pool that provides idle connections to applications when the application requests a connection to a JMS provider.
