spring——获取ClassLoader

  public static ClassLoader getDefaultClassLoader() {
        ClassLoader cl = null;

        try {
            cl = Thread.currentThread().getContextClassLoader();
        } catch (Throwable var3) {
            ;
        }

        if(cl == null) {
            cl = ClassUtils.class.getClassLoader();
            if(cl == null) {
                try {
                    cl = ClassLoader.getSystemClassLoader();
                } catch (Throwable var2) {
                    ;
                }
            }
        }

        return cl;
    }
