servlet thread safe

First we have to understand the lifecycle of the servlet: The server creates only a single instance of each servlet, and its Init method is invoked the first time the servlet is created, so Init is where the one-time setup code is placed, and then a

Summary:Web technology has become one of the mainstream Internet Web application technologies, and Servlet is the core foundation of Java Web technology. This article first discusses the origin of the servlet from the background of the application

The servlet architecture is built on the Java multithreading mechanism, whose life cycle is the responsibility of the Web container.When a client requests a servlet for the first time, the servlet container instantiates the Servlet class based on
