activemq api

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

One, ACTIVEMQ high availability architectureACTIVEMQ's high availability architecture is based on the Master/slave model. ACTIVEMQ provides a total of four configuration scenarios to configure Ha, where shared nothing master/slave is no longer used after version 5.8, and zookeeper-based replicated is introduced in the ActiveMQ5.9 version LevelDB Store ha scenario.Second, the configuration explanation of Mas

Two-way communication is the use of a channel can either receive messages or send messages. The message that is pushed to Broker

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

1. Basic Concepts ActiveMQ: It is the most popular and powerful open source message bus that is produced by Apache. is a JMS provider implementation that fully supports the JMS1.1 and Java EE 1.4 specifications. JMS (Java Messaging Service): is a Java platform for message-oriented middleware (MOM) APIs for sending messages between two applications, or distributed systems, for asynchronous communication. 2. JMS Message mode 1 point to point or queue m

For the persistence of the ACTIVEMQ message, we introduced it briefly in the second section, and today we will analyze the persistence process of activemq and the persistence of plug-ins in detail. In the production environment to ensure the reliability of the message, we are certainly faced with the problem of persistent messages, today, together to conquer him. 1. Introduction to the way of persistence We
