不用spring,hibernate超傻瓜JAVA开发(javabean+数组)

核心提示:javabean+数组优点:1、简单:java程序中最简单的类莫过于javabean,javabean有一套成熟的规范,不用spring,hibernate超傻瓜JAVA开发(javabean+数组),易于编写2、方便:javabean是数据的载体,既可以通过set和get方式来操作数据,所以没有任何学习曲线示例:vi
javabean+数组优点:

1、简单:java程序中最简单的类莫过于javabean,javabean有一套成熟的规范,易于编写

2、方便:javabean是数据的载体,既可以通过set和get方式来操作数据,又可以象使用数组一样来操作javabean

3、通用:通过下标来操作javabean,你所写的代码将是通用的,可移植的。你所写的功能组件将适用于所有的javabean

4、0配置:通过数组来对javabean进行说明配置,比xml文件更清晰

5、易于修改:程序中不再有任何SQL语句,数据结构发生改变,只要修改javabean即可

6、易于维护:由于第3点的通用性,你只需要维护页面及操作逻辑。

7、傻瓜性:会操作数组就会使用,所以没有任何学习曲线

 数组property指明了该javabean所具有的属性
 property = new String[] { "member", "name", "password", "email", "type", "useable", "createTime" };

 数组field指明了属性分别对应的字段
 field = new String[] { "member", "name", "password", "email", "type", "useable", "createTime" };

 数组propertyName指定了属性的中文名称
 propertyName = new String[] { "帐号", "昵称", "密码", "邮箱", "类型", "状态", "注册时间" };

setPropertyValue方法可以对javabean任何一个属性赋值,而且自动进行类型转换,改变程序到处都是类型转换的状况
