Correct way of reading a file in src/main/resources as string in a web application?

Question

I have a web application which has following structure (partial).

Project Name
   src/main/java
       com.package
           MainFile.java
   src/main/resources         


        

Answer 1

Try this:

 ClassLoader loader = SomeClass.class.getClassLoader();
 InputStream is = loader.getResourceAsStream("sample.xml"));

 byte[] b = null;
 int numBytes = is.read(b);

resources should be in the classpath and ClassLoader should find it for you.

Answer 2

This file is in the web app classpath, so you can get it like:

Path path = Paths.get(getClass().getResource("/sample.xml").toURI());
return new String(Files.readAllBytes(path));
