jms message producer

The 1,JMS specification supports two types of message delivery: Persistent and non-persistent. ACTIVEMQ supports the recovery of messages, intermediate status messages (message is cached in memory) when both types of delivery are supported2,ACTIVEMQ can store messages in three types of media: file-based (stored in a file), in-memory (stored in memory), relational

Today, my colleague asked me how to handle the JMS messages of receive and visible. A little bit ignorant, before the state of the message has never been concerned. In the Weblogic81, we can't see the message in destination, we can only see how many messages there are in the current destination, how many pending are there. And in 92, when we monitor the destinati

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").

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

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.Par
