The simplest single threadLet's start with the basics. Regardless of which application server or framework you use (such as Tomcat, Jetty, and so on), they all have a similar base implementation. The Web service is based on a socket socket, which is responsible for listening to the port, waiting for TCP connections, and accepting TCP connections. Once the TCP connection is accepted, the data can be read and
