java如何解析\*.properties文件

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);

classpath:

InputStream in = new BufferedInputStream(new FileInputStream(UserController.class.getResource("/conf/imgftp.properties").getFile()));
Properties p = new Properties();
p.load(in);
String path = p.getProperty("imgtfs.domain");
System.out.println(path);

属性文件：

#商户编号
p1_MerId=10001126856

测试文件：

InputStream in;
try {
in = new BufferedInputStream(new FileInputStream("D:/workspaces/TestPay/src/com/test/merchantInfo.properties"));
Properties p = new Properties();
p.load(in);
String p1 = p.getProperty("p1_MerId");
System.out.println(p1);

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

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);
