IBM WATSON-自然语言分类器服务(Java SDK)-DeleteClalsifier()方法不会删除分类器

Question

我正在尝试在IBM Watson平台中的自然语言分类器服务中调用deleteclalsifier((方法，该操作已完成，但并未删除分类器。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：

我在这里做错了什么？

Answer 1

需要使用.execute()

调用DeleteClalifier

将.execute()添加到

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

下面的方法将删除您的分类器

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