信息绑定ResourceBundle

package com.util.db;

import java.util.ResourceBundle;

public class ConnectionConfig {

          private static ResourceBundle config = null;

                   static {
                             config = ResourceBundle.getBundle("com.util.db.conndb");
                   }

                   public static String getUserName() {
                             return config.getString("USERNAME");
                   }

                   public static String getPassword() {
                             return config.getString("PASSWORD");
                   }

                   public static String getDriver() {
                             return config.getString("DRIVER");
                   }

                   public static String getUrl() {
                             return config.getString("URL");
                   }

         }
在com.util.db.conndb这个包下还要有一个conndb.properties文件
