数据绑定实战策略-实例eclipse工程下载和部署以及浏览
数据绑定实战策略-实例eclipse工程下载和部署以及浏览：
1.下载本文的附件-mvc-databind.zip
http://dl.iteye.com/topics/download/6b4fc8b6-79dd-325f-b32a-4b69354b35a5
2.解压mvc-databind.zip ，将其中的工程导入eclipse即可查看文中相关的源代码
3.部署，准备好tomcat 6和jdk 15或以上的版本
4.在tomcat 6的conf\Catalina\localhost下增加mvc.xml文件，内容为：
用户可以根据自己的实际情况设置docBase属性的值
5.启动tomcat，输入以下地址即可访问mvc的数据绑定实例了：
http://localhost:8080/mvc/examples/index.page
附带说明一下，本文是参考bbossgroups 3.2版本功能编写。
