jquery读取本地json文件 使用J2SE API读取Properties文件的六种方法

使用J2SE API读取Properties文件的六种方法  

　　使用J SE API读取Properties文件的六种方法　　　　 使用java util Properties类的load()方法　　　　示例 InputStream in = lnew BufferedInputStream(new FileInputStream(name));　　Properties p = new Properties();　　p load(in);　　　　 使用java util ResourceBundle类的getBundle()方法　　　　示例 ResourceBundle rb = ResourceBundle getBundle(name Locale getDefault());　　　　 使用java util PropertyResourceBundle类的构造函数　　　　示例 InputStream in = new BufferedInputStream(new FileInputStream(name));　　ResourceBundle rb = new PropertyResourceBundle(in);　　　　 使用class变量的getResourceAsStream()方法　　　　示例 InputStream in = JProperties class getResourceAsStream(name);　　Properties p = new Properties();　　p load(in);　　　　 使用class getClassLoader()所得到的java lang ClassLoader的getResourceAsStream()方法　　　　示例 InputStream in = JProperties class getClassLoader() getResourceAsStream(name);　　Properties p = new Properties();　　p load(in);　　　　 使用java lang ClassLoader类的getSystemResourceAsStream()静态方法　　　　示例 InputStream in = ClassLoader getSystemResourceAsStream(name);　　Properties p = new Properties();　　p load(in);　　　　补充　　　　Servlet中可以使用javax servlet ServletContext的getResourceAsStream()方法　　　　示例 InputStream in = context getResourceAsStream(path);　　Properties p = new Properties();　　p load(in);　　　　完整的示例 可以参考附件文件　　　　如何上传文件 谁知道请告诉以下 只好把source都贴上来了　　　　JProperties java文件　　　　/**　　** This program is free sofare 　　**　　** You
