1.创建一个空白的maven项目servlet，作为父工程，以后就在这个父工程中创建module，删除src，导入依赖
<dependencies>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>
</dependencies>
2.右击父项目servlet创建一个module，servlet_helloServlet
创建一个类
public class HelloServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { System.out.println("run HelloServlet.doGet()..."); PrintWriter writer = resp.getWriter(); writer.print("hello servlet"); } @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { super.doPost(req, resp); } }
3.修改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_4_0.xsd" version="4.0" metadata-complete="true"> <servlet> <servlet-name>helloServlet</servlet-name> <servlet-class>com.cong.servlet.HelloServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>helloServlet</servlet-name> <url-pattern>/hello</url-pattern> </servlet-mapping> </web-app>
4.配置tomcat，运行，进入首页
5.访问我们写的类的doGet()方法，打印了hello servlet
servlet-第一个servlet项目，helloServlet
