I am trying to include the file testrules.drl in my Java code but it keeps giving me a NullPointerException. Am I declaring the relative path correctly? I tried it with the absolute path but I still get the same error....
private static String DRL_FILE = "/src/main/resources/rules/testrules.drl";
...
Reader reader = new InputStreamReader(Main.class.getResourceAsStream(DRL_FILE)); //this gives a NullPointeException
Below is the image:
试试这个
new InputStreamReader("src/main/resources/rules/testrules.drl");
