我正在尝试在 IBM Watson 平台的自然语言分类器服务中调用 deleteClassifier() 方法，操作完成但不会删除分类器。这是我的代码和输出：

代码：

NaturalLanguageClassifier service = new NaturalLanguageClassifier();
service.setUsernameAndPassword("xxxxxxx", "yyyyyyy");

System.out.println("Before deleting: ");
Classifier classifier;
classifier = service.getClassifier("90e7acx197-nlc-38920").execute();
System.out.println(classifier);

service.deleteClassifier("90e7acx197-nlc-38920");

System.out.println("After deleting: ");
classifier = service.getClassifier("90e7acx197-nlc-38920").execute();
System.out.println(classifier);

输出：

我在这里做错了吗？

需要使用 deleteClassifier 调用.execute()

添加.execute()到

service.deleteClassifier("90e7acx197-nlc-38920");

以下方法将删除您的分类器

service.deleteClassifier("90e7acx197-nlc-38920").execute();
