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();
		}

结果就不贴了，一下几种方法可自行测试~

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);
