java 中获取 resource ，适用于 jar 内资源

getResouces.java

InputStream in = getClass().getClassLoader().getResourceAsStream("ParseResult.groovy");
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder builder = new StringBuilder();
String aux = "";

while ((aux = reader.readLine()) != null) {
    builder.append(aux);
}

String text = builder.toString();
