Original address: http://blog.csdn.net/haoxingfeng/article/details/9167895When we integrate with spring, for consumers we have three different types of listeners to choose from, they are messagelistener,sessionawaremessagelistener, Messagelisteneradapter, let's talk about the difference between them.1, MessageListenerMessageListener is the most primitive message listener and is the interface defined in the JMS specification. The OnMessage (Message mes

In previous articles in this series, we focused on JDBC's handling of local transactions, and this article will cover an example of a distributed transaction.Please download the GitHub source code in the following ways:git clone https://github.com/davenkin/jta-atomikos-hibernate-activemq.gitThe difference between a local transaction and a distributed transaction is that a local transaction is only used to process a single data source transaction (such as a single database), and a distributed tra

Java Message Service(The Java Messaging Service, referred to as JMS) solves this problem partly by providing a way to interact with Java EE applications or traditional systems. The universal interface collection of JMS sends or receives messages asynchronously. Receiving messages asynchronously is clearly the best choice for clients that use intermittent network connections, such as mobile phones and PDAs.

Some time ago, I was told by a colleague that there are a lot of message status for receive in the client, which can only be consumed if the JMS server or WebLogic server is fully charged. After investigation, this problem may be a bug in the WebLogic, of course, does not exclude the possibility of the specific environment. Let's take a look at the root cause of the problem, which helps us to understand more about the implementation of WebLogic

The distributed transaction about the Dubbo service framework, although it is not urgent to do, but can be discussed. I think the management of affairs should not belong to the Dubbo framework,Dubbo can only be managed by the transaction,Like JDBC and JMS are distributed resources that can be managed by transactions.Dubbo as long as the same behavior can be managed by the transaction, such as can be rolled back,The scheduling of other transactions sho

Running environment: Weblogic 92, jdk150 Through the JMX service of weblogic, we can directly obtain mbeans to monitor the JMS server, instead of opening the weblogic online console for manual monitoring every time, which can be completely automated. The source code is as follows: Import java. io. IOException; Briefly introduce this code, To capture mbeans of JMX, initialize the MBean object first,JmsService = new ObjectName ( You can check the N

Temporaryqueue and temporarytopic can be seen literally as "temporary" destinations. You can create a session, for example:Temporaryqueue replyqueue = session. createtemporaryqueue ();Although they are created by sessions, their life cycle is indeed the entire connection. If two sessions are created on one connection, the temporaryqueue or temporarytopic created by one session can also be accessed by another session. If the two sessions are created by different connections, the temporaryqueue cr

JMeter User GuideThis article focuses on the status of the JMeter tools in the test and some of them are difficult to understand or unclear in the handbook, readers can understand these concepts through this article, and then according to their own needs to consult the specific use of JMeter components to complete the test work.　1.

The two message transmission modes Topic and Queue in the Jms specification are compared as follows (): 　 Topic Queue Summary Publish Subscribe messaging Publish and Subscribe messages Point-to-Point Status or not Topic data is stateless by default. By default, Queue data is stored as files on the mq server. For example, Active MQ is generally stored under $ AMQ_HOME/data/kr-store/data. You can also config

The company's technology platform in the docking of IBM MQ message middleware with a broker, messages sent to MQ have more message header information:RHF2, resulting in the reception of the message is not working properly. Record how this problem is handled here.A parameter, targetclient, is provided in IBM MQ that can be used to control whether the message header is enabled in a JMS message. When using JMS

restarts at D2, the publisher sends M6 and M7. Now S'll receive M4, M5 followed by M6 and M7 and all for future messages. i.e. S would receive all messages from M1. M7. This is the difference between durable and non-durable consuming. If S were a non-durable consumer then it would only has received M1, M2, M3 and M6, M7-not M4 and M5. i.e because the subscription is durable, S would receive every message sent to T whether the Subscriber are running or not. For non-durable topics, only messages

Spring Integrated JMS Usage The JMS full name Java Message Service, which is used to send messages. 1. Advantages1. Relative RPC achieves the decoupling effect: Decoupling from the Service Interface name (changing the interface name in RPC, the client needs to make modifications), decoupling from the service location (RPC needs to configure the service's network location to use the service),

JMS-based Active MQ message storage, jmsmqI. Message Storage Methods ActiveMQ supports persistent messages and non-persistent messages in JMS specifications. Persistent messages are usually used to ensure that messages are consumed by consumers regardless of whether the consumers are online or not. After the message is confirmed to be consumed, it will be deleted from the storage. Non-persistent messages
