java - DocumentBuilderFactory 无法设置功能 FEATURE_SECURE_PROCESSING

Question

我正在尝试创建一个FEATURE_SECURE_PROCESSING设置为DocumentBuilderFactory 的实例true。当我尝试 setFeature 时，我不断收到 ParserConfigurationException。

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        try{
            factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
        }
        catch (ParserConfigurationException e){ //Always gets here
            e.printStackTrace();
        }
