Spring: how to locate a file in WEB-INF/classes/resources

The project if built with Spring and has the standard filesystem of Maven.


Assume we want to read foo.txt in WEB-INF/classes/resources/foo.txt

ClassPathResource r = new ClassPathResource("foo.xml");
try {
 System.out.println("full path"+r.getFile().getAbsolutePath());
} catch (IOException e1) {
 e1.printStackTrace();
}

The output is the full path to foo.xml.
