Course Introduction:1. The importance of message persistence Message persistence is one of the core functions of message middleware. It ensures that messages will not be lost during transmission. In JavaActiveMQ, the message persistence mechanism can ensure that messages will not be lost even in the event of message broker or network failure. 2. Message persistence mechanism ActiveMQ achieves message persistence by storing messages in persistent storage media (such as disks or databases). When the message broker receives a persistent message, it writes the message to the persistent storage medium.

Persistence strategy ActiveMQ supports a variety of persistence

Course Introduction:The event processing and messaging mechanism in the PHP framework implements communication between components by listening to specific events and executing callback functions. The messaging mechanism implements asynchronous processing by sending and receiving messages in a message queue. Practical cases include user registration events, order processing events, and email sending messages, highlighting the role of this mechanism in building scalable, maintainable, and responsive web applications.
