1. 新建maven项目，选择maven骨架maven-archetype-webapp来建立web项目
2. 选择next，输入groupid：MavenWebTest， artifactid：cn.test
3. 建好后在项目区域出现的MavenWebTest的目录结构
如下图：
4. 默认建立没有java的目录，我们来建立一个文件夹来存放java类
5. 修改项目pom文件
加入servlet-api.jar，另再加入jetty插件的配置，使得当web项目开发完后能用Jetty容器来运行。
pom的配置信息如下：访问端口为9111

6. 建立servlet类
public class HttpServletDemo extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 4230239235404655360L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException {
response.setContentType("text/html;charset=GB2312");
PrintWriter printWriter = response.getWriter();
String title = "HelloServlet";
String heading1 = "HelloServlet的doGet方法的输出：";
printWriter = response.getWriter();
printWriter.print("<HTML><HEAD><TITLE>" + title + "</TITLE>");
printWriter.print("</HEAD><BODY>");
printWriter.print(heading1);
printWriter.println("<h1><p>:您好</h1>");
printWriter.print("</body></HTML>");
printWriter.write("");
printWriter.flush();
printWriter.close();
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException {
doGet(request, response);
}
}
7. 配置web.xml文件
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>TomcatWeb</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>MavenWeb</servlet-name>
<servlet-class>maven.servlet.HttpServletDemo</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MavenWeb</servlet-name>
<url-pattern>/servlet/HttpServletDemo</url-pattern>
</servlet-mapping>
</web-app>
8. 配置jetty来运行web项目
配置好后点击右下角的Run按钮来运行
9. 浏览器访问
程序运行后，在浏览器输入：http://localhost:9111，即可看到后台返回的信息
