Six Methods for reading properties files using Java

Use j2se API to read properties files

1. Use the load () method of Java. util. properties class

Example:

Inputstream in = lnew bufferedinputstream (New fileinputstream (name ));

Properties P = new properties ();

P. Load (in );

2. Use the getbundle () method of the Java. util. resourcebundle class

Example:

Resourcebundle RB = resourcebundle. getbundle (name, locale. getdefault ());

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

Example:

Inputstream in = new bufferedinputstream (New fileinputstream (name ));

Resourcebundle RB = new propertyresourcebundle (in );

4. Use the getresourceasstream () method of the class variable

Example:

Inputstream in = jproperties. Class. getresourceasstream (name );

Properties P = new properties ();

P. Load (in );

5. Use the getresourceasstream () method of Java. Lang. classloader obtained by class. getclassloader ()

Example:

Inputstream in = jproperties. Class. getclassloader (). getresourceasstream (name );

Properties P = new properties ();

P. Load (in );

6. Use the getsystemresourceasstream () Static Method of the Java. Lang. classloader class

Example:

Inputstream in = classloader. getsystemresourceasstream (name );

Properties P = new properties ();

P. Load (in );

Supplement

You can use the getresourceasstream () method of javax. servlet. servletcontext in servlet.

Example:

Inputstream in = context. getresourceasstream (PATH );

Properties P = new properties ();

P. Load (in );
