jsp+servlet实现猜数字游戏（jsp+servlet项目）硬核推荐

文章摘要

这篇文章介绍了一个使用Spring Boot框架实现的猜数字游戏客户端代码。在该代码中，`HandleGuess`类继承自`HttpServlet`，实现了`doPost`和`doGet`方法。`doPost`方法用于处理客户端提交的猜测数字，通过获取会话对象中的保存值与猜测数字进行比较，并根据比较结果设置会话属性，发送重定向至`inputNumber.jsp`页面。`doGet`方法调用`doPost`方法以实现异步操作。代码的主要功能是实现客户端端的猜数字游戏逻辑。

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;
import javax.servlet.http.HttpSession;

public class HandleGuess extends HttpServlet {
public void doPost(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException{
request.setCharacterEncoding(“utf-8”);
response.setContentType(“text/html;charset=utf-8”);
PrintWriter out=response.getWriter();
//获取客户猜测提交的数
int guessNumber=Integer.parseInt(request.getParameter(“guessnumber”));
//获取客户的会话对象
HttpSession session=request.getSession();
Integer integer=(Integer)session.getAttribute(“saveNumber”);
int realNumber=integer.intValue();
System.out.println(realNumber);
System.out.println(guessNumber);
if(guessNumber>realNumber){
session.setAttribute(“message”, “您猜大了”);
System.out.println(“您猜大了—no”);
response.sendRedirect(“inputNumber.jsp”);
}
else if(guessNumber<realNumber){
session.setAttribute(“message”, “您猜小了”);
System.out.println(“您猜小了—no”);
response.sendRedirect(“inputNumber.jsp”);
}
else{
session.setAttribute(“message”, “您猜对了”);
System.out.println(“您猜对了”);
response.sendRedirect(“inputNumber.jsp”);
}
}
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException{
doPost(request,response);
}
