<div style="padding: 0px; margin: 0px;">1。使用Java.util.Properties类的load()方法
示例：InputStreamin=lnewBufferedInputStream(newFileInputStream(name));
Propertiesp=newProperties();
p.load(in);
2。使用java.util.ResourceBundle类的getBundle()方法
示例：ResourceBundlerb=ResourceBundle.getBundle(name,Locale.getDefault());
3。使用java.util.PropertyResourceBundle类的构造函数
示例：InputStreamin=newBufferedInputStream(newFileInputStream(name));
ResourceBundlerb=newPropertyResourceBundle(in);
4。使用class变量的getResourceAsStream()方法
示例：InputStreamin=JProperties.class.getResourceAsStream(name);
Propertiesp=newProperties();
p.load(in);
5。使用class.getClassLoader()所得到的java.lang.ClassLoader的getResourceAsStream()方法
示例：InputStreamin=JProperties.class.getClassLoader().getResourceAsStream(name);
Propertiesp=newProperties();
p.load(in);
6。使用java.lang.ClassLoader类的getSystemResourceAsStream()静态方法
示例：InputStreamin=ClassLoader.getSystemResourceAsStream(name);
Propertiesp=newProperties();
p.load(in);
补充
Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream()方法
示例：InputStreamin=context.getResourceAsStream(path);
Propertiesp=newProperties();
p.load(in);
