可以按照以下步骤在 Postman 中测试该方法:
1. 打开 Postman,选择 POST 请求方式,并输入该接口的 URL:http://yourdomain.com/page。
2. 在请求体中选择 "raw" 选项,并选择 JSON 格式。输入以下示例 JSON 数据:
{
"phoneNumber": "13800138000",
"userId": "123456",
"name": "张三"
}
3. 点击 "Send" 按钮发送请求,即可在返回结果中查看该方法的执行结果。如果执行成功,会返回一个包含分页信息的 JSON 数据。

import java.io.*; import javax.servlet.*; import javax.servlet.http.*, public class HelloCounter extends HttpServlet{ private int visits=0: public void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException,IOExceptions{ response.setContentType ("text/html; charset=\"UTF-8\""); PrintWriter servletOut = response.getWriter(); visits++; PrintVisitNum(servletOut, new Integer(visits).toString()); servletOut.close(); } private void PrintVisitNum(PrintWriter servletOut,String visits){ //we assume that the codes have been rightly implemented to print the visits and they are omitted here.} }Modify the HelloCounter servlet and rename it the VisitorCounter servlet. In the VisitorCounter servlet, you are required to create a session so that the number of visitors to the page, rather than the number of visits, is displayed. Note that you are only required to explain how the code should be modified and write the modified code accordingly.
To modify the HelloCounter servlet into the VisitorCounter servlet with session tracking, you can make the following changes:
1. Rename the class from HelloCounter to VisitorCounter.
2. In the doGet method, retrieve the session object from the request using request.getSession() method.
3. Within the session object, retrieve the visitor count attribute using session.getAttribute("count"), and if it does not exist, set it to 0 using session.setAttribute("count", 0).
4. Increment the visitor count using session.setAttribute("count", count + 1).
5. Print the visitor count to the response using the PrintWriter object.
6. Close the PrintWriter object.
The modified code would look like this:
```
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class VisitorCounter extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html; charset=\"UTF-8\"");
PrintWriter servletOut = response.getWriter();
HttpSession session = request.getSession();
Integer count = (Integer) session.getAttribute("count");
if (count == null) {
count = 0;
}
count += 1;
session.setAttribute("count", count);
servletOut.println("<html><head><title>Visitor Counter</title></head><body>");
servletOut.println("<h1>Visitor Count: " + count + "</h1>");
servletOut.println("</body></html>");
servletOut.close();
}
}
```
Note: This code assumes that the web.xml file has been correctly configured to map the servlet to a URL.
编写一个JSP页面,该页面提供一个表单,用户可以通过表单输入梯形的上底、下底和高的值,并提交给本JSP页面,该JSP页面将计算梯形面积的任务交给一个page bean去完成。JSP页面使用getProperty动作标记显示page bean中的数据,例如梯形的面积
以下是一个简单的实现,包含JSP页面和page bean:
梯形计算器页面(trapezoid.jsp):
```
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>梯形计算器</title>
</head>
<body>
<h1>梯形计算器</h1>
<form method="post" action="${pageContext.request.contextPath}/TrapezoidCalculator">
<label for="upperBase">上底:</label>
<input type="number" name="upperBase" id="upperBase" required><br>
<label for="lowerBase">下底:</label>
<input type="number" name="lowerBase" id="lowerBase" required><br>
<label for="height">高:</label>
<input type="number" name="height" id="height" required><br>
<button type="submit">计算</button>
</form>
<c:if test="${not empty calculator}">
<p>梯形面积为<c:out value="${calculator.area}" /></p>
</c:if>
</body>
</html>
```
梯形计算器page bean(TrapezoidCalculator.java):
```
package com.example;
public class TrapezoidCalculator {
private double upperBase;
private double lowerBase;
private double height;
private double area;
public void calculate() {
area = (upperBase + lowerBase) * height / 2;
}
public double getUpperBase() {
return upperBase;
}
public void setUpperBase(double upperBase) {
this.upperBase = upperBase;
}
public double getLowerBase() {
return lowerBase;
}
public void setLowerBase(double lowerBase) {
this.lowerBase = lowerBase;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public double getArea() {
return area;
}
}
```
梯形计算器Servlet(TrapezoidCalculatorServlet.java):
```
package com.example;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/TrapezoidCalculator")
public class TrapezoidCalculatorServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
TrapezoidCalculator calculator = new TrapezoidCalculator();
calculator.setUpperBase(Double.parseDouble(request.getParameter("upperBase")));
calculator.setLowerBase(Double.parseDouble(request.getParameter("lowerBase")));
calculator.setHeight(Double.parseDouble(request.getParameter("height")));
calculator.calculate();
request.setAttribute("calculator", calculator);
request.getRequestDispatcher("trapezoid.jsp").forward(request, response);
}
}
```
在Web应用程序的WEB-INF目录下,需要创建一个web.xml文件,以将Servlet映射到URL:
```
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_4_0.xsd"
id="WebApp_ID" version="4.0">
<display-name>trapezoid-calculator</display-name>
<welcome-file-list>
<welcome-file>trapezoid.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>TrapezoidCalculatorServlet</servlet-name>
<servlet-class>com.example.TrapezoidCalculatorServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TrapezoidCalculatorServlet</servlet-name>
<url-pattern>/TrapezoidCalculator</url-pattern>
</servlet-mapping>
</web-app>
```
这样,当用户在浏览器中访问http://localhost:8080/trapezoid-calculator/时,将显示梯形计算器页面。用户可以输入梯形的上底、下底和高,提交表单后,页面将显示梯形的面积。
