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:\Tomcat\apache-tomcat-9.0.1-windows-x64\apache-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:\javaEE\javaWorkplace\SpringDemo\WebContent\WEB-INF\lib(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:

恭喜,web项目已经成功搭建!
</body>

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!
