We've learned how to deploy ACTIVEMQ in the front,We know that the task queue can be viewed through a management background in ACTIVEMQ.TodayUsing PHP to manipulate ACTIVEMQ, we can use a third-party extension.Download:require fusesource/stomp-php:2.0.*Then create a new test.php:require __DIR__.‘/vendor/autoload.php‘; //引入自动加载的文件$connect = new \FuseSource\Stomp\Stomp(‘tcp://10.211.55.13/:61613‘);$connect->c

Brief Introduction Actual combat one, the actual combat two introduced the basic concept and the configuration way of ACTIVEMQ. This article introduces a way to use spring to send, consume topic, queue type messages. Do not understand the topic and queue of Google. As shown in the illustration, topic and queue represent a topic and a queue message channel respectively. Topicmessageproducer sends messages to topic, Topicconsumera and Topicconsumerb

logic The following shows the encoding template for JMS: Send side: Java code publicclassqueuesender{ publicstaticvoidmain (String[]args) throws jmsexception{ Connectionfactoryfactory=newactivemqconnectionfactory ("tcp://localhost:61616");//Here for simplicity, A JMS implementation that relies on ACTIVEMQ. In a real-world program, you can find factory through Jndi lookups, which completely avoids associating specific JMS implementations. a

The directory after ACTIVEMQ is extracted as follows: Each directory is described as follows: Bin:activemq's startup script conf:activemq all profile data: Log file and persistent message DOCS:ACTIVEMQ official documentation EXAMPLES:ACTIVEMQ the official demo LIB:ACTIVEMQ Run the required library WEBAPPS:ACTIVEMQ Web console WEBAPPS-DEMO:ACTIVEMQ WebApps related demo ACTIVEMQ-ALL-5.13.2.JAR:ACTIVEMQ CLI ja

DeliveryMode refers to whether messages that were not consumed in the original queue or subject remain when the ACTIVEMQ is restarted I have done the following tests myself through the code, and the test steps and results are as follows: Create the producer and set the producer DeliveryMode to persistent and run producer Restart ACTIVEMQ before the message is consumed by consumer

. If it exists, then broker checks to see if any consumer owns the message group. If not, then broker selects a consumer and associates it with this message group. Thereafter, this consumer will receive all messages from this message group until: consumer is closed. Message group is closed. By sending a message and setting the JMSXGROUPSEQ for this message to 0. Starting with version 4.1, ACTIVEMQ supports a Boolean field Jmsxgroupfirstforconsumer. Th
