Finding all CLASSPATH resources matching a pattern

Question

I want to read a bunch of text files, by loading them as resources using the context classloader.

URL url = Thread.currentThread()
                .getContextClassLoader()
                .getResource("folder/foo.txt");

Is there some way to get a list of resources whose names match a given pattern? For eg:

URL[] matchingUrls = someLibrary.getMatchingResources("folder/*.txt");

Libraries like Spring can scan the classpath to find classes with a given annotation, so I am wondering if there something similar to load a bunch of resources.

Answer 1

Comment from "Binil Thomas" was on the right track, I was looking for confirmation that Spring's PathMatchingResourcePatternResolver could be used from Java Config so that I could give the resulting "Resource" list to the Spring Hibernate SessionFactory.mappingLocations without having to update the list of Hibernate *.hbm.xml files every time a new mapping file was added. I was able to achieve this with the PathMatchingResourcePatternResolver using the below code:

import org.hibernate.SessionFactory;
import org.springframework.core.io.Resource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.core.io.support.ResourcePatternResolver;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
...
ResourcePatternResolver patternResolver = new PathMatchingResourcePatternResolver();   
Resource [] mappingLocations = patternResolver.getResources("classpath*:mappings/**/*.hbm.xml");
sessionFactory.setMappingLocations(mappingLocations);

Works like a charm.

Just use:

@Value("classpath:folder/*.xml")
Resource[] resources;
