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

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 databases (stored in a relational database)What is the use of 3,persistence message?Persi

"The election will be based on the size of the message log, the weight, the larger the version stamp (data is up-to-date), the higher the weight of the broker takes precedence to master, and the other broker as slave and follow master." 】Third, referencesQuorum mechanism of Distributed system theoryHttps://activemq.apache.org/artemis/docs/1.0.0/ha.ht

model, there are the following concepts: Theme (Topic), Publisher (publisher), Subscribers (subscriber). The client sends the message to the topic. Multiple publishers send messages to topic, which the system passes to multiple subscribers.? Each message can have multiple consumers? There is a time dependency between the Publisher and the Subscriber . Subscribers to a topic (TOPIC) must create a subscription before they can consume the publisher's message and, in order to

In addition, the message in the above example we send only strings, in fact, can also send the object type of message, can even use Messagecreator custom message conversion, instead of using the Convertandsend method default conversion.Sending messages between multiple applications1.
