Course Introduction：Advanced concepts of JMS include message groups, message selectors, transaction and confirmation modes, and dead letter queues. The message group ensures that the same group of messages are processed by the same consumer through JMSXGroupID to ensure sequence; the message selector filters messages based on attributes, such as MessageConsumerconsumer=session.createConsumer(topic,"eventType='login'"); the transaction supports Session.SESSION_TRANSACTED mode, realizing the atomicity of sending and receiving operations; the dead letter queue captures multiple failed messages, facilitates subsequent analysis and retry, and improves the system's fault tolerance capabilities.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
