eclipse中通过Jetty和Maven构建web工程

工程结构图

构建过程

1-maven构建项目

2-新建web目录

3-新建web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" metadata-complete="false"
version="3.1">

<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>com.edwin.maven.LearnJetty.HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Hello</servlet-name>
<url-pattern>/hello/*</url-pattern>
</servlet-mapping>

</web-app>

4-新建HelloServlet

package com.edwin.maven.LearnJetty;

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 HelloServlet extends HttpServlet
{
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
response.setContentType("text/html");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().println("<h1>Hello Servlet</h1>");
response.getWriter().println("session=" + request.getSession(true).getId());
}
}

5-修改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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>

<artifactId>LearnJetty</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>

</project>

6-启动Jetty服务器

7-访问网页
