使用模板创建项目

1）maven-archetype-quickstart : 普通的java项目

1.1 File-->New-->Project-->Empty Project

1.2 File-->New-->Module-->Maven

1.3 填写Maven工程的坐标

2）maven-archetype-webapp : web工程

在pom.xml文件引入jsp和servlet依赖

    <!--加入servlet依赖(servlet的jar包)-->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.1.0</version>
      <scope>provided</scope>
    </dependency>
    <!--jsp的依赖(jsp相关的jar包加入)-->
    <dependency>
      <groupId>javax.servlet.jsp</groupId>
      <artifactId>jsp-api</artifactId>
      <version>2.1</version>
      <scope>provided</scope>
    </dependency>

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<body>
<h2>Hello World!</h2>
<a href="hello">访问servlet</a>
</body>
</html>

web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
    <servlet>
        <servlet-name>HelloServlet</servlet-name>
        <servlet-class>com.bjpowernode.controller.HelloServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>HelloServlet</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
</web-app>

HelloServlet类

public class HelloServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html;charset=utf-8");
        PrintWriter pw = response.getWriter();
        pw.println("Hello Maven Web");
        pw.flush();
        pw.close();
    }
}

3）将web项目打包成war包交付给客户，客户将该war包部署到tomcat的webapps文件夹下，就能运行了

自动解压该war包

运行
