java:jsp: ResourceBundle国际化多语言

java提供了一个资源类java.util.ResourceBundle来试下多国语言版本。其实ResourceBundle只是一个抽象的类，她有两个子类：ListResourceBundle,和,PropertyResourceBundle.前一个子类需要编写不同的国家语言信息放置在对象类中，下面将实例演示，后一个子类是需要编写不同国家语言的文件后缀为.properties（）来存放语言信息，这部分内容读者可以在国际化标签以及Struts时了解到。例如，存放在RES_zh_EN.propertieh和存放英文的RES_en_US.properties资源文件.

 package cn.com.resouce;
 import java.util.ListResourceBundle;

 public class RES_zh_CN extends ListResourceBundle {

     static final Object[][] contents = new String[][]{
         {"version","这是中文版"},
         {"title","中文版本"},
         {"index","首页"},
         {"news","新闻"},
         {"life","生活"},
         {"sports","体育"},
         {"entertainment","娱乐"}
     };

     @Override
     protected Object[][] getContents() {
         // TODO Auto-generated method stub
         return contents;
     }

 }

 package cn.com.resouce;
 import java.util.ListResourceBundle;

 public class RES_en_US extends ListResourceBundle {

     //创建对应的中文文本信息

     static final Object[][] contents = new String[][]{

         {"version","this is english"},
         {"title","english"},
         {"index","index"},
         {"news","news"},
         {"life","life"},
         {"sports","sports"},
         {"entertainment","entertainment"}
     };

     @Override
     protected Object[][] getContents() {
         // TODO Auto-generated method stub
         return contents;
     }

 }
