在Eclipse中建立Maven Web项目

2022-11-20 18:00:47

一、软件版本

Eclipse Java EE IDE for Web Developers. Version: Neon Release (4.6.0)

Maven 3.3.9

Servlet 2.5

tomcat9

jdk1.8

本文将定Eclipse已配置好jdk和tomcat。

二、创建步骤

1、新建一个maven web项目

1.1 打开Eclipse，Ctrl + N 弹窗新建向导，如下图

1.2 在搜索框中输入 maven project，

1.3 选择 Next ，选择好工作区间

1.4 选择 Next ，这里选择webapp结尾的骨架来创建web项目

1.5 输入好信息后，点击finish

1.7 至此，一个初始的maven web项目就建好了，目录结构如下：

2、项目属性的基本设置

2.1更改项目属性为UTF-8。

2.2更改项目依赖的jdk为本地jdk。

2.3更改项目的其他属性

3、更改项目的部署路径

4、编写程序

这里编写一个简单servlet。首先在pom.xml中引入servlet依赖。

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">

	<modelVersion>4.0.0</modelVersion>

	<groupId>com.kang</groupId>

	<artifactId>WebTest</artifactId>

	<packaging>war</packaging>

	<version>0.0.1-SNAPSHOT</version>

	<name>WebTest Maven Webapp</name>

	<url>http://maven.apache.org</url>

	<dependencies>

		<dependency>

			<groupId>junit</groupId>

			<artifactId>junit</artifactId>

			<version>3.8.1</version>

			<scope>test</scope>

		</dependency>

		<dependency>

			<groupId>javax.servlet</groupId>

			<artifactId>servlet-api</artifactId>

			<version>2.5</version>

			<scope>provided</scope>

		</dependency>

	</dependencies>

	<build>

		<finalName>WebTest</finalName>

	</build>

</project>

然后在src/main/java目录下建立一个servlet。

MyTest.java

package com.kang;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

 * Servlet implementation class MyTest

 */

public class MyTest extends HttpServlet {

	private static final long serialVersionUID = 1L;

    /**

     * @see HttpServlet#HttpServlet()

     */

    public MyTest() {

        super();

        // TODO Auto-generated constructor stub

    }

	/**

	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)

	 */

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		// TODO Auto-generated method stub

		response.getWriter().append("Served at: ").append(request.getContextPath());

	}

	/**

	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)

	 */

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

		// TODO Auto-generated method stub

		doGet(request, response);

	}

}

最后编写jsp页面。

index.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>Insert title here</title>

</head>

<body>

Hello World!

	<a href="http://localhost:8080/WebTest/MyTest">request.getContextPath()</a>

</body>

</html>

5、运行到tomcat上
