使用java读取war文件中的Manifest.mf

Question

I am trying to read MANIFEST.MF inside a war file. I am using Eclipse .

InputStream inputStream = getClass().getClassLoader().getResourceAsStream(
    "/META-INF/MANIFEST.MF"
);
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

I have this code but I am getting java.lang.NullPointerException error. I have my war file inside my project folder.

Any advice is much appreciated. Thank you!

确保您的war文件是您的classpath一部分，否则您尝试做的将不起作用。
