Get file's mime type by path

Load properties file to beans in spring mvc

In Java 7 you can now just use Files.probeContentType(path)

eg:

try {
        String mimeType = Files.probeContentType(FileSystems.getDefault().getPath(filePath+fileName));
        response.setContentType(mimeType);
        IOUtils.copy(inputStream, response.getOutputStream());
    } finally {
        IOUtils.closeQuietly(inputStream);
    }
