学习Eclipse NLS

今天研究了1下Eclipse的NLS,觉得不错,与大家分享....
messages.properties
key_1=hello world,here is NLS
key_2=hello {0}, welcome to my blog
key_3=hello {0}, please reply to{1} if you like this article
其中的 {0} 代表MessageHelper.bind(MessageHelper.key_2, "gembin"); 里的第1个参数,一次类推
public class MessageHelper extends NLS {
   //com.exmple.messages 中的点将会被转换成"/"
  // 所以最终的路径为:com/exmple/messages.properties
    private static final String BUNDLE_NAME = "com.exmple.messages"; //$NON-NLS-1$
    public static String key_1;
    public static String key_2;
    static{
        initializeMessages(BUNDLE_NAME, MessageHelper.class);
        
    }
 
    /**
     * Bind the given message's substitution locations with the given string value.
     *
     * @param message
     *            the message to be manipulated
     * @param binding
     *            the object to be inserted into the message
     * @return the manipulated String
     */
    public static String bind(String message, Object binding) {
        return NLS.bind(message, binding);
    }

    /**
     * Bind the given message's substitution locations with the given string values.
     *
     * @param message
     *            the message to be manipulated
     * @param binding1
     *            An object to be inserted into the message
     * @param binding2
     *            A second object to be inserted into the message
     * @return
     */
    public static String bind(String message, Object binding1, Object binding2) {
        return NLS.bind(message, binding1, binding2);
    }

    /**
     * Bind the given message's substitution locations with the given string values.
     *
     * @param message
     *            the message to be manipulated bindings
     * @param bindings
     *            An array of objects to be inserted into the message
     * @return the manipulated String
     */
    public static String bind(String message, Object[] bindings) {
        return NLS.bind(message, bindings);
    }

    /**
     * Initialize the given class with the values from the specified message bundle.
     *
     * @param bundleName -
     *            fully qualified path of the class name
     * @param clazz -
     *            the class where the constants will exist
     */
    @SuppressWarnings("unchecked")
    public static void initializeMessages(String bundleName, Class clazz) {
        NLS.initializeMessages(BUNDLE_NAME, MessageHelper.class);
    }
    
    public static void main(String sp[]){
  
          String s=MessageHelper.bind(MessageHelper.key_2, "hello");
          System.out.println(s);
    }

}
