如何在MyEclipse中将项目部署Tomcat

如果系统里面还没有配置Tomcat，请参照《Windows下如何配置tomcat环境变量》。

1.新建一个web project项目。如下：

效果如下：

2.编写一个实现Servlet接口或继承HttpServlet的Java类

 1 package com.cnblogs.daliu_it.web;
 2 
 3 import java.io.IOException;
 4 import java.io.PrintWriter;
 5 import javax.servlet.ServletException;
 6 import javax.servlet.http.HttpServlet;
 7 import javax.servlet.http.HttpServletRequest;
 8 import javax.servlet.http.HttpServletResponse;
 9 
10 public class HelloWorld extends HttpServlet {
11     protected void service(HttpServletRequest req, HttpServletResponse resp)
12             throws ServletException, IOException {
13         resp.setContentType("text/html");
14         PrintWriter out = resp.getWriter();
15         out.write("<h1>Hello Servlet");
16         out.close();
17     }
18 }

3.修改web.xml文件。

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
 5     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 6     <display-name></display-name>
 7     <servlet>
 8         <servlet-name>HelloWorld</servlet-name>
 9         <servlet-class>com.cnblogs.daliu_it.web.HelloWorld</servlet-class>
10     </servlet>
11 
12     <servlet-mapping>
13         <servlet-name>HelloWorld</servlet-name>
14         <url-pattern>/HelloWorld</url-pattern>
15     </servlet-mapping>
16     <welcome-file-list>
17         <welcome-file>index.jsp</welcome-file>
18     </welcome-file-list>
19 </web-app>
