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
目 录 [ - ]
    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:
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="D:\workspace\bbossgroups-3.2\bestpractice\mvc\WebRoot" path="/mvc" debug="0" reloadable="false">
</Context>

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
