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);
     }
 }
