ResourceBundle

1：java.util.ResourceBundle的主要用途？

2：java.util.ResourceBundle的简单测试用法：

package one; import java.util.Locale; import java.util.ResourceBundle; public class ResourceBundleTest { public static void main(String[] args ) { Locale myLocale = Locale.getDefault(); ResourceBundle myResource = ResourceBundle.getBundle("resource" , myLocale) ; System.out.println(myResource.getString("mi.hello")); System.out.println(myResource.getString("mi.name")); } }

在同目录下新建资源文件：resource.properties

资源文件内容如下：

mi.hello=HELLO mi.name=WORLD

看看另外一种读取*.properties的方法

private static String configFile =
      "cn/com/jdlssoft/zxsb/app/interfaces/Impl.properties";
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
    InputStream in = classLoader.getResourceAsStream(configFile);
    Properties prop = new Properties();
    try {
      prop.load(in);
    }
    catch (IOException ex) {
      logger.error("<外部接口管理> 配置文件读取错误！可能原因为" + ex);
    }
    Enumeration enumeration = prop.keys();
    while (enumeration.hasMoreElements()) {
      String key = (String) enumeration.nextElement();
      String value = prop.getProperty(key);
      map.put(key, value);
    }
