jsp/servlet solves the problem of garbled characters

Problem description: When we output Chinese to the page (html/jsp) or read the Chinese on the page, garbled characters appear.

The main reason for this problem is because: the default encoding format of the browser and the compiler is different.

Just let the browser and the compiler use the same rules for encoding and decoding.

Note: Not all encoding rules support Chinese, the encoding "UTF-8" is used here.

Code demo:

package ziyang;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class CeShi extends HttpServlet {

	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		/ / Solve the garbled text of the read page
		request.setCharacterEncoding("UTF-8");
		/ / Solve the Chinese garbled input to the page
		response.setContentType("text/html;charset=UTF-8");
		//Read an input element in the page, its name="user"
		System.out.println(request.getParameter("user"));
		response.getWriter().write("Momada");
		
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doGet(request, response);
	}
}
