How does the JSP use the page instruction to make the JSP file support Chinese encoding?Does the JSP file support Chinese encoding?

jsp introduction:

The full name of JSP is Java Server Pages, which is a dynamic web page technology. JSP is actually a file formed by inserting java code and JSP tags into html, and the file name ends with .jsp.In fact, JSP is a servlet.
Writing html in servlet is more painful, and writing JSP is like writing html, but compared with html, html can only provide users with static data, that is, static pages, and Jsp technology allows java to be nested in pagescode to provide users with dynamic data to form dynamic pages.It should be noted that it is best to only write java code for dynamic output in JSP.

JSP workflow
Converting JSP files to .java files and compiling them to .class filesThe process is all completed by tomcat. There is a translation engine inside tomcat. When the JSP page is accessed for the first time, the translation engine converts it into a .java file and compiles a .class file.Then run the class file again.
The html code in JSP will be translated into out.write() in servlet

The following describes the method sharing of JSP files supporting Chinese encoding, as shown below:

Implementation ideas: 1. Use the pageEncoding attribute to set the encoding method in the page instruction (using the JSP file itself to support Chinese) 2. Set the charset value in the contentType,Use the client to support Chinese

Example

<%@ page language="java" contentType="text/html;charset=GBK" pageEncoding="GBK"%>
Set JSP Chinese encoding, pageEncoding property test
