版本：
一、创建Project或者创建Module，选择Maven
二、填写相关信息
三、完善文件目录
创建后的文件目录：
完善目录：
在新建的文件夹上右击--选择Mark Directory as--可以指定文件夹性质，以上main下的java、resources和test下的java、resources分别为：
Sources Root、Resources Root、Test Sources Root、Test Resources Root
四、在pom.xml文件中添加servlet和jsp依赖
<!--加入servlet依赖，servlet的jar-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
<!--jsp依赖，jsp相关的jar加入进来-->
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>
五、创建Servlet
package com.qxzh.servlet;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
@WebServlet(name = "HelloServlet")
public class HelloServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=utf-8");
PrintWriter pw = response.getWriter();
pw.write("Hello Maven Web");
pw.flush();
pw.close();
}
}
六、配置web.xml文件
<!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.qxzh.servlet.HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
</web-app>
七、配置tomcat
下拉：
八、编写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>
九、运行tomcat
成功
