ACTIVEMQ the process of sending and receiving messages is similar to the JDBC Operations database: First create the Connection connection object, then the session object, and then create producer, Consumer, Objects such as message, except that ACTIVEMQ connection objects are generated through the Activemqconnectionfactory factory. Here are the test code for some scenarios. Define some constant data, which i

Activemq runs stably and data throughput is high. If the incoming or outgoing queue is slow, check your ownCodeIs it too slow to process the obtained data. The performance optimization mentioned in this Article is to list some important points. Please make sure your project has no problems: 1. Use spring jmstemplate The send and convertandsend modes of jmstemplate use persistent mode even if non_persistent is set. This slows down the inbound que

The reconnection mechanism is one of the specific manifestations of activemq's high availability. Specifically, you can use the Failover method to connect to one or more brokerurls after the connection is disconnected. For example: failover :( TCP: // 127.0.0.1: 61616). Multiple URLs can be used here. By default, if the client and the broker are disconnected directly, the client starts a new thread, Continuously obtain a URL from the URL parameter to retry the connection. This mechanism has a pr

Objective 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 specification, although the JMS specification has been around for a long time, but JMS still plays a special role in the middle of today's Java EE applications. First, use the introduction environment prepa

Brief introductionIn the previous article discussed several application system integration methods, found that the actual Message Queuing-oriented integration scheme is a more reasonable overall choice. Here, we first discuss a specific message queue ACTIVEMQ Basic communication method. ACTIVEMQ is an implementation of the JMS message Communication specification. In general, the most common types of message
