如何用Spring读取JAR中的文件

URL url = getClass().getClassLoader().getResource("com/yyy/1.txt");
InputStreamReader inputStreamReader = new InputStreamReader(url.openStream());
char[] data = new char[100];
inputStreamReader.read(data);
assertEquals((new String(data)).trim(),"ddddd");

com/yyy/1.txt放在jarfile.jar中
