java servlet programming

Differences and connections between servlet, filter, Listener, Interceptor First, the concept 1.servlet:servlet is a server-side Java application that has platform-and protocol-independent features and can dynamically generate Web pages that work in the middle tier of client requests and server responses. 2.filter:filter is a reusable code fragment that can be used to transform HTTP requests, responses,

First, introduce A Servlet filter can dynamically intercept requests and responses to transform or use information contained in a request or response.You can attach one or more servlet filters to a servlet or a set of servlet. Servlet filters can also be attached to JavaSer

The Java servlet, as the preferred server-side data processing technology, is rapidly replacing CGI scripts. One of the advantages of servlet beyond CGI is that not only can multiple requests share common resources, but it can also preserve persistent data between different user requests. This paper introduces a practical technique to give full play to this featu

Since jdk1.3, Java has introduced the concept of dynamic proxy. Dynamic proxy helps you reduce the number of lines of code and improve code reusability. For example, you do not have to write the same log code lines for all the methods of the class, instead of the dynamic proxy class of the category class. Of course, this kind of convenience is conditional. This article briefly introduces the principle of Java
