Maven的学习资料收集--(四)使用Maven构建Web项目-测试

[-]

  1. 在srcmainjava下新建一个Servlet
  2. 修改webxml
  3. 新建JSP
  4. 测试

在上一篇博客里,我们使用Maven构建了一个Web项目,我们在这里写一个简单的Servlet,测试一下。

1.在src/main/java下,新建一个Servlet
<span style="font-weight: normal;">package com.deppon.text01.action;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class UserServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
	
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doPost(request , response);
	}
	
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		request.setCharacterEncoding("UTF-8");
		response.setContentType("text/html;charset=utf-8");
		
		String action = request.getParameter("action");
		if("login_input".equals(action)) {
			request.getRequestDispatcher("login.jsp").forward(request , response);
		} else if("login".equals(action)) {
			String name = request.getParameter("name");
			String password = request.getParameter("password");
			
			System.out.println("name->" + name + ",password->" + password);
		}
	}

}</span>

2. 修改web.xml

<pre name="code" class="html"><span style="font-weight: normal;"><?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  
  <servlet>
    <servlet-name>UserServlet</servlet-name>
    <servlet-class>com.deppon.text01.action.UserServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>UserServlet</servlet-name>
    <url-pattern>/user</url-pattern>
  </servlet-mapping>
  
</web-app></span>
 
  

3. 新建JSP

index.jsp

<span style="font-weight: normal;"><%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
		<title>Hello Maven</title>
	</head>
	
	<body>
		<p>大家好!</p>
		<a href="user?action=login_input">去登录</a>
	</body>
</html></span>

login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
	<head>
	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
	<title>登录界面</title>
	</head>
	
	<body>
		<form action="user?action=login" method="post">
			Name:<input type="text" name="name" />
			Password:<input type="password" name="password" />
			
			<input type="submit" value="登录" />
		</form>
	</body>
</html>

其实,构建完成之后,开发的话,应该和平时开发Web项目是一样的。

之前忘记说明pom文件了,需要添加依赖的:

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <name>test01 Maven Webapp</name>
  <url>http://maven.apache.org</url>
  
  <!-- 属性配置 -->
  <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <!-- 依赖配置 -->

    <dependency>

      <scope>test</scope>
    </dependency>
    
    <!-- 添加Servlet -->
