应用中为自定义classloader获取parent classloader的一般逻辑

GetParentClassloader.java

private static ClassLoader getParentClsLoader() {
        ClassLoader ctxLoader = Thread.currentThread().getContextClassLoader();
        if (ctxLoader != null) {
            try {
                ctxLoader.loadClass(CurrentClass.class.getName());
                return ctxLoader;
            } catch (ClassNotFoundException e) {
            }
        }
        return CurrentClass.class.getClassLoader();
    }
