The JMS API defines five types of message bodies: --------------------------------------------------------------------------------------------------------------- ----Stream-The message body of the Streammessage object contains the Java programming language primitive value stream ("Java basic type"). Populate and read sequentially.Map-The message body of the Mapmessage object contains a set of name-value pairs, where the name is a String object and th

Ack_mode Confirm Mode --------------------------------------------------------------------------------------------------------------- -----The confirmation mode is used to indicate how the session confirms receipt of the message, which needs to be specified when using the connection CreateSession method, and the following four options are included in the JMS session interface· Auto_acknowledge = 1 Automatic ConfirmationThe session automatically confi

This article is a simple integration method for spring and activemq. It is only used for reference learning and focuses on understanding concepts. 1: JMS is a set of standard APIs developed by Sun to access message-oriented middleware (MOM). The mom component used in this article is activemq. You can go to [url] routing, It is very simple to use, extract and directly run the activemq. BAT file under the D:/activemq-4.1.1/bin directory, you can start t

In the development of message-oriented middleware, it is often necessary to generate a unique message identifier. You can add a corresponding prefix to the server deployed in the project, and then the timestamp is too long based on the system timestamp, it can be converted into a 36-digit string to form the unique identifier of the message: import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;public class MsgIDUtil {private static fi

Jar hell III: the issue and solution of log4j 1.2.15 in m2eclipse　　 The version 1.3 of log4j is still in the Alibaba Cloud version. Version 1.2 is up to version 1.2.15, but maven2 has an issue in eclipse. After installing Maven clean, the maven package will build failure, with the following warning information:[Warning] invalid Pom for javax.

As mentioned earlier, JMSCorrelationID is mainly used to associate multiple messages. For example, when a Message needs to be repliedSet JMSCorrelationID to the ID of the original message. In the following example, three message producers A, B, C and three message consumers A, B, and C are created. Producer A sends A message to consumer A, and consumer A needs to send A message to consumer. B and C are similar to.The diagram is as follows:Producer A ----- send ----> consumer A ----- reply ------

JMS message persistence: Persistence of ActiveMQ messages to mySql database ActiveMQ5.8.0 uses kahadb as the default message persistence mode. By using the default persistence mechanism, we cannot directly see how the message persists. The JDBC persistence mechanism provided by ActiveMQ can store persistent information to the database. By viewing the table structure and stored data generated by ActiveMQ in the database, we can better understand the me

The last blog introduced the ACTIVEMQ based on JMS point-to-point messaging mechanism implementation, here is another publish/subscribe method implementation. Publish subscription model It's like subscribing to a newspaper. We can choose one or more newspapers, for example: Beijing daily, People's daily. These newspapers are equivalent to topic in the release subscription model. If a lot of people subscribe to the same newspaper, we are registered in
