Eclipse下创建Spring MVC web程序--非maven版

首先，安装eclipse和tomcat，这里我下载的是tomcat9.0版本64位免安装的：地址https://tomcat.apache.org/download-90.cgi

免安装的如何启动和关闭Tomcat呢？鼠标双击就可以了

下面，打开eclipse: 导航栏File->New->Dynamic Web Project, 填写好project name，有人说过，给项目起名字一定要认真，就像给自己孩子起名字一样，这样才能又唯一标识！这里由于是第一个Spring项目，起名为SpringDemo，如下图所示：

点击New Runtime选择你的Tomcat，这里我选择最新版的9.0：

点击Next, 选择Tomcat的位置:D:Tomcatapache-tomcat-9.0.1-windows-x64apache-tomcat-9.0.1， JRE选择你安装的jre即可, 点击finish即可

配置如下，点击finish完成

完成后如下：

下面就是要下载Spring jar包了，这里给一个链接，根据该链接的一步一步下载即可: http://www.cnblogs.com/leavescy/p/7657476.html

将刚才的jar包放到E:javaEEjavaWorkplaceSpringDemoWebContentWEB-INFlib（即你工程的目录下），然后重启eclipse,就会看到

创建相关配置文件和控制文件：

ViewController.java

package com.springmvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class ViewController {
    @RequestMapping(value="/hello")
     public String hello(Model model) {
        
        model.addAttribute("greeting", "Hello Spring MVC");
         
        return"index";
         
    }

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>${greeting}</title>
</head>
<body>
    恭喜，web项目已经成功搭建!
</body>
</html>

右键项目->Run As->Run on Server:

表示没有错误，此时在浏览器中输入：http://localhost:8080/SpringDemo/hello

此时，表示项目成功！

注意：关于免安装的Tomcat的配置，请参考：http://www.cnblogs.com/leavescy/p/7676262.html

maven版和非maven版的最大区别在于Tomcat的启用方式！
