What is jsp framework?

The full name of JSP is Java Server Pages, and the Chinese name is java server page. It is basically a simplified Servlet design. It is a dynamic web page technology standard advocated by Sun Microsystems and established with the participation of many companies.

JSP technology is somewhat similar to ASP technology. It is inserted into traditional web page HTML (a subset of Standard Universal Markup Language) files (*.htm, *.html) Java program segment (Scriptlet) and JSP tag (tag), thus forming a JSP file with the suffix (*.jsp). Web applications developed with JSP are cross-platform and can run under Linux as well as other operating systems.

In short, jsp is used to write java dynamic pages. It can be regarded as a language. The pages written by it are eventually compiled into servlets for execution. It is hard to talk about the framework. Generally speaking, it is the java framework.

Then the java framework is a collection of classes and interfaces, through which a series of program implementations are completed through coordination of these classes and interfaces. The JAVA framework can be divided into three layers: presentation layer, business layer and physical layer. The framework is also called a semi-finished product under development. It cannot provide everything for the entire WEB application, but with the framework, we can focus on the development of business logic without having to worry about its technical implementation and some auxiliary business logic. The well-known Structs and Spring are powerful representatives of the presentation layer and business layer frameworks.
