I\'m trying to read my META-INF/MANIFEST.MF file from my Spring Boot web app (contained in a jar file).

I\'m trying the following code:

        Input         


        

Answer 1

    try {
        final JarFile jarFile = (JarFile) this.getClass().getProtectionDomain().getCodeSource().getLocation().getContent();
        final Manifest manifest = jarFile.getManifest();
        final Map manifestProps = manifest.getMainAttributes().entrySet().stream()
                .collect(Collectors.toMap(entry -> entry.getKey(), entry -> entry.getValue()));
    ...
    } catch (final IOException e) {
        LOG.error("Unable to read MANIFEST.MF", e);
        ...
    }

This will work only if you launch your app via java -jar command, it won't work if one create an integration test.
