How to list files under a tomcat 6 webapp

Question

I have a spring boot project that is deployed on Tomcat 6. I have a list of files under project's resource directory and I am trying to list all files under that directory. I am able to get specific file if I specify classpath:abc.txt in the getResource() method. However I am wondering if there is a way to just list all files with a wild card or something.

Answer 1

You cannot do like this MyClass.class.getResource('*.txt'). The alternative to this is :

ServletContext      sc                      =       request.getSession().getServletContext();
    String          strPath                 =       sc.getRealPath("/");
File[]          allFiles          =       new File(strpath).listFiles(new FilenameFilter()    {
    @Override
    public boolean accept(File dir, String name) {
        return name.toLowerCase().endsWith(".txt");
    }
});
