JSP（Java Server Page）は、SunMicrosyst

JSP (Java Server Page) is a dynamic technology standard developed by Sun Microsystems in 1999 and is installed by many companies. JSP is a new generation of dynamic content programming technology that inherits the capabilities of Java technology from "write once, run anywhere", separating developer development and maintenance from the platform [3]. Rich content and dynamic web pages are created thanks to HTML, DHTML, XML and more. This allows web developers to quickly and easily build a web platform and build powerful websites. Because JSPs separate the user interface from the content hierarchy, web developers do not have to change the underlying dynamic content when changing the overall layout. <br>The Java program segment inserted in the JSP may work. When a JSP page on the server is executed for the first time, the JSP mechanism on the server first translates the JSP page file into a Java file, then compiles the Java file into a bytecode file, and then the client request. Respond to. By executing the bytecode file and requesting the JSP to be re-executed, the JSP engine responds to the client by directly executing the bytecode file. This is also why JSP is faster than ASP. In addition, JSP has made improvements in many other ways. This has the advantage of separating dynamic pages from static pages, bypassing hardware platform limitations and allowing them to run after compilation. This completely overcomes the performance flaws at the ASP script level.

JSP（Java Server Page）是由Sun Microsystems于1999年开发的动态技术标准，由很多企业安装。JSP是动态内容编程的新一代技术，继承了Java技术的功能“写一次，到处执行”，将开发者的开发和维护从平台分离出来[3]。多亏HTML、DHTML、XML等，丰富的内容和动态的网页被制作出来。这样一来，Web开发者就能快速简单地构建Web平台，构筑强大的Web网站。由于JSP可以将用户界面从内容层次中分离出来，因此Web开发者在改变整体布局时无需变更基础动态内容。<br>有时JSP中插入的Java程序段会起作用。第一次执行服务器上的JSP页面时，服务器上的JSP机构首先将JSP页面文件转换成Java文件，然后编译Java文件生成字节码文件，然后响应客户的请求。通过执行字节码文件，若要求重新执行JSP，JSP引擎将直接执行字节码文件，以响应客户。这也是JSP比ASP快的理由。此外，JSP在其他很多方面都有所改善。这有一个优点是将动态页面从静态页面中分离出来，可以避免硬件平台的限制，在编译后执行。这将完全克服ASP脚本水平的性能缺陷。<br>
