Servlet----------在使用doGet()和doPost()是如何处理中文乱码

如果在登录界面跳转到时servlet中使用doGet()方法显示中文出现乱码时，可以添加这两行代码来解决，但这不是唯一的方法

request.setCharacterEncoding("GBK");
response.setContentType("text/html;charset=GBK")

如我的

package cn.servlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Login extends HttpServlet {
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        request.setCharacterEncoding("GBK");//解决乱码
        response.setContentType("text/html;charset=GBK");//解决乱码
        
        String name=request.getParameter("login");
        String password=request.getParameter("password");
        response.setCharacterEncoding("GBK");
        PrintWriter out = response.getWriter();
        out.println("欢迎-- "+name+" --登录！"+"</br>");
        out.print("你的登录密码是："+password);    
    }
    public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        this.doGet(request, response);
    }
}
