- 在使用Java处理图形应用时,经常有人推荐设置 -Djava.awt.headless=true,具体含义和效果查了一下,记录在这里分享 Headless模式是系统的一种配置模式。在该模式下,系统缺少了显示设备、键盘或鼠标。 Headless模式虽然不是我们愿意见到的,但事实上我们却常常需要在该模式下工作,尤其是服务器端程序开发者。因为服务器(如提供Web服务的主机)往往可能缺少前述设备,但又需要使用他们提供的功能,生成相应的数据,以提供给客户端(如浏览器所在的配有相关的显示设备、键盘和鼠标的主 (1)

使用J2SE API读取Properties文件的六种方法
1。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);
2。使用java.util.ResourceBundle类的getBundle()方法
示例:
ResourceBundle rb = ResourceBundle.getBundle(name, Locale.getDefault());
3。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);
4。使用class变量的getResourceAsStream()方法
示例:
InputStream in = JProperties.class.getResourceAsStream(name);
Properties p = new Properties();
p.load(in);
5。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);
6。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
