读配置文件load出错。求原因。

prop = new Properties();
try{
prop = new Properties();
prop.load(new FileReader(BasicFactory.class.getClassLoader().getResource("config.properties").getPath()));
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(e);
}

    load报错，说The method had  Inputstream in the type properties is not applicable for the arguments (Filereader) .
            求解决方法

先用文件路径new 一个File 然后再传给FileReader
