一些小问题:
关于maven无法创建servlet可以点击查看:《idea 的maven无法创建servlet》


先创建一个maven工程,流程如下:

以上maven工程创建完成了。

Maven使用入门,小案例

  1. 按照以上步骤,创建的maven工程,结构如下:

  2. maven目录结构里面缺少了Java源文件夹,需要我们手动添加上去,过程如下:

    先新建目录

3.再将新建的文件设置为源文件

4.在java新建包,再在包里新建一个servlet,关于maven无法创建servlet,可以参考前言里的解决办法进行相应设置,

项目的结构如图:

servlet代码如下:

package aa.bb;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;@WebServlet("/testServlet")public class TestServlet extends HttpServlet {protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {request.getRequestDispatcher("/test.jsp").forward(request, response);    }    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {doPost(request, response);    }}

jsp代码如下:

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>Title</title></head><body>hello!!!Maven</body></html>

pom.xml配置
