[转]Java读取Properties文件的六种方法
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));
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));
4。使用class变量的getResourceAsStream()方法
示例: InputStream in = JProperties.class.getResourceAsStream(name);
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);
6。使用java.lang.ClassLoader类的getSystemResourceAsStrea
示例: InputStream in = ClassLoader.getSystemResourceAsStrea
补充
Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream()方法
示例:InputStream in = context.getResourceAsStream(path);
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
