Whether you care or not, Java Web applications use a thread pool more or less to process requests. The implementation details of the thread pool may be overlooked, but the use and tuning of the thread pool will need to be understood sooner or later. This article mainly describes the use of the Java thread pool and how to properly configure the thread pool. Singl

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 con

The structs can be automatically encapsulated for parameters, which is also simple.One, the action parameter is automatically encapsulated:1, you can declare properties of public, accept parameters directly in the action class.2, the attribute is also private, if it is private, you need to provide a setter method, you can also provide getter method as needed.3,struts can automatically convert types, typically we pass string-type arguments, and struts can be converted to the default declared vari
