几种读取属性文件的JAVA实现方式
1.使用java.util.Properties类的load()方法
示例:
Java代码
InputStream in = lnew BufferedInputStream(new FileInputStream(name));
Properties p = new Properties();
p.load(in);
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:
Java代码
ResourceBundle rb = ResourceBundle.getBundle(name, Locale.getDefault());
ResourceBundle rb = ResourceBundle.getBundle(name, Locale.getDefault());
3.使用java.util.PropertyResourceBundle类的构造函数
示例:
Java代码
InputStream in = new BufferedInputStream(new FileInputStream(name));
ResourceBundle rb = new PropertyResourceBundle(in);
InputStream in = new BufferedInputStream(new FileInputStream(name));
ResourceBundle rb = new PropertyResourceBundle(in);
4.使用class变量的getResourceAsStream()方法
示例:
Java代码
InputStream in = JProperties.class.getResourceAsStream(name);
Properties p = new Properties();
p.load(in);
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:
Java代码
InputStream in = JProperties.class.getClassLoader().getResourceAsStream(name);
Properties p = new Properties();
p.load(in);
InputStream in = JProperties.class.getClassLoader().getResourceAsStream(name);
Properties p = new Properties();
p.load(in);
6.使用java.lang.ClassLoad
