Using Netty as a basic WebSocket server and client implementation: Netty includes classes and utilities for building both WebSocket servers and clients, simplifying the development process. Full code: For example, Netty's EventLoopGroups use daemon threads by default and thus an application with only daemon threads running besides the main thread will exit as soon as the main thread completes. In order to understand pipelines, consider a Pizza Delivery scenario. DBUpdateClient in order to update the users. 1 Annotation-based CORS Configuration. Have another look on the netty example code, there is a Handler class also for printing out the response. The previous sections covered already many common use cases, such as compression, SSL or HTTP/2.
