Is jsp still used now?

#jsp is still needed. Now many large e-commerce websites are made of jsp.

JSP (full name JavaServer Pages) is a dynamic web page technology standard created by Sun Microsystems. JSP is deployed on the network server and can respond to requests sent by the client and dynamically generate Web pages of HTML, XML or other format documents based on the request content, and then return them to the requester. JSP technology uses Java language as a scripting language to provide services for users' HTTP requests, and can handle complex business requirements together with other Java programs on the server.

jsp features:

Can easily and efficiently add dynamic web content in a templated way.

JavaBean and tag library technology can be used to reuse commonly used function codes (designed components are easy to reuse and reduce duplication of work). The tag library not only comes with common built-in tags (JSTL), but also supports custom tags with extensible functionality.

Have good tool support.

Inherits the relative ease of use of the Java language.

Inherits the cross-platform advantages of Java and realizes "write once, run anywhere". Because there are many development platforms that support Java and related technologies, website developers can choose to develop JSP on the system platform that is most suitable for them; JSP projects developed in different environments can be successfully accessed on all clients.

The dynamic (the part that controls the changing content)/static (the part that does not need to change the content) areas in the page are combined in a scattered but orderly manner, allowing people to see the page code more intuitively The overall structure also makes it easy to separate the two parts of designing page effects and program logic (separation of appearance view and logic). This makes it easier to allocate personnel and leverage their respective strengths to achieve efficient division of labor and cooperation.

Can cooperate with other enterprise-level Java technologies. JSP can only be responsible for the presentation of data in the page to achieve layered development.
