Java Read properties configuration file [Go]

Several common ways to read. properties files in online articles

1. Example of the load () method using the Java.util.Properties class :

InputStream in = Lnew bufferedinputstream (new  FileInputStream (name));    New Properties ();   

2. Using the Getbundle () method of the Java.util.ResourceBundle class

ResourceBundle RB = Resourcebundle.getbundle (name, Locale.getdefault ());   

Use ResourceBundle to read. properties files to avoid path problems
When I read the. properties file in the jar, I always can't find the file path and later read the. properties file with ResourceBundle to avoid the path problem, the code is as follows:


Process is the file name, remember not to add. Properties, URL is the key name in the file

ResourceBundle bundle = Resourcebundle.getbundle ("com.ihandy.smsoc.app.process");      = Bundle.getstring ("URL");  System.out.println (s);   = S;  

3. Use the constructor of the Java.util.PropertyResourceBundle class

New Bufferedinputstream (new  FileInputStream (name));    New propertyResourceBundle (in);   

4. The getResourceAsStream () method using class variables

InputStream in = class name. class . getResourceAsStream (name);    New Properties ();   P.load (in);

5. Example of the Java.lang.ClassLoader getResourceAsStream () method obtained using Class.getclassloader () :

InputStream in = class name. class . getClassLoader (). getResourceAsStream (name);    New Properties ();   P.load (in);

6. Examples of Getsystemresourceasstream () static methods using the Java.lang.ClassLoader class :

InputStream in = classloader.getsystemresourceasstream (name);    New Properties ();   P.load (in);   

7. The Javax.servlet.ServletContext getResourceAsStream () method can be used in the servlet example:

InputStream in = context.getresourceasstream (path);    New Properties ();   P.load (in);
