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：

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"; } }

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！
