浅谈 BbossMVC 数据绑定
浅谈 BbossMVC 数据绑定，本文介绍BbossMVC框架的数据绑定功能。包括数字绑定，字符串绑定，日期类型绑定，日期数组类型绑定，bean对象绑定，List绑定，Map绑定，枚举类型绑定，枚举类型数组绑定。
相关的框架包请及时更新最新版本
本文涉及的技术包括：mvc，aop/ioc,taglib,jsp

1.数据绑定实战策略-实例eclipse工程下载和部署以及浏览
2.数据绑定实例-jsp页面
3.数据绑定实例-控制器实现
4.数据绑定控制器配置文件-bboss-helloworld.xml
1.数据绑定实战策略-实例eclipse工程下载和部署以及浏览
1.1.下载本文相关附件-mvc-databind.zip
http://dl.iteye.com/topics/download/6b4fc8b6-79dd-325f-b32a-4b69354b35a5
1.2.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
1.3.部署，准备好tomcat 6和jdk 15或以上的版本
1.4.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
1.5.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
2.数据绑定实例-jsp页面
3.数据绑定实例-控制器实现
3.1.控制器实现类
3.2.依赖的值对象-ExampleBean
3.3.依赖的枚举类型对象-SexType
4.数据绑定控制器配置文件-bboss-helloworld.xml
附带说明一下，本文是参考bbossgroups 3.2版本功能编写
