HTTP狀態405 -HTTP方法GET不受此URL支持。指定的HTTP方法不允許用於請求的資源

-1

幫我在這裏傢伙...我已經添加了servlet jar文件和mysql連接器jar文件，但它顯示錯誤，如HTTP狀態405 - 此方法不支持HTTP方法GET。所請求的資源不允許指定的HTTP方法。我嘗試了所有可能的解決方案，但我遇到了同樣的錯誤。HTTP狀態405 -HTTP方法GET不受此URL支持。指定的HTTP方法不允許用於請求的資源

Regform.java

package com.servlet.info; 

import java.io.IOException; 
import java.io.PrintWriter; 
import java.sql.Connection; 
import java.sql.DriverManager; 
import com.mysql.jdbc.Driver; 
import java.sql.PreparedStatement; 

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


public class Regform extends HttpServlet { 


@Override 
protected void doPost(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 

    response.setContentType("text/html"); 
    PrintWriter out = response.getWriter(); 

    String fNM = request.getParameter("firstName"); 
    String lNM = request.getParameter("lastName"); 
    String eID = request.getParameter("emailID"); 
    String uNM = request.getParameter("userName"); 
    String pass = request.getParameter("password"); 

    try{ 

    //loading drivers for mysql 
     com.mysql.jdbc.Driver mySqlDriverClassRef = new com.mysql.jdbc.Driver(); 
     DriverManager.registerDriver(mySqlDriverClassRef); 
//creating connection with the database 
    Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student_form?&useSSL=false", "j2ee" ,"j2ee"); 
    PreparedStatement ps=con.prepareStatement 
       ("insert into student values(?,?,?,?,?);"); 

    ps.setString(1, fNM); 
    ps.setString(2, lNM); 
    ps.setString(3, eID); 
    ps.setString(4, uNM); 
    ps.setString(5, pass); 
    int i=ps.executeUpdate(); 

     if(i>0) 
     { 
     out.println("You are sucessfully registered"); 
     } 

    } 
    catch(Exception e) 
    { 
     e.printStackTrace();

嘗試增加以下到Java，看看它是否工作

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