Processing of RHF2 message headers in ibm mq message middleware jms messages, mqrhf2
When the company's technical platform is connected to a brokerage with ibm mq message middleware, the message header information is added to the message sent to MQ: RHF2, resulting in abnormal message receiving and processing. Record how the problem is handled here.
The targetClient parameter is provided in ibm mq to control whether the message header is enabled in

A message object is divided into three parts: Headers, Properties, and Payload ). For StreamMessage andMapMessage, the message itself has a specific structure, while TextMessage, ObjectMessage, and BytesMessage are unstructured. A message can contain some important data or only notifications of an event.The Headers section of a message usually contains some message descriptions, which are standard descriptions.

First, we will briefly introduce ActiveMQ. ActiveMQ is an open-source free Message Server provided by the Apache Software Foundation. Its current version is 5.8.0.
ActiveMQ has the following features

Activemq is the most popular and powerful open-source message bus produced by Apache. Activemq is a JMS provider that fully supports the jms1.1 and J2EE 1.4 specifications. Although it has been a long time since the JMS specifications were introduced, however, JMS still plays a special role in today's J2EE applications.
Main features:
1. Write clients in multiple
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.
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
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
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
