如何从 Datastore Google Cloud 检索文本类型?
How to retrieve Text type from Datastore Google Cloud?
好的,这些都是基本问题,但是在网上找到的答案不多。
好的,现在,我使用此 Java 代码
插入数据存储
Text descriptionText=new Text(description);
structureEntity.setUnindexedProperty("Description",descriptionText);
Anh 这是检索代码:
Text description=(Text)structureObjectEntity.getProperty("Description");\
System.out.println(description);
现在,假设我将“We should arrive before dark.<br>I should have finished the book by Friday. <br>The roads should be less crowded today.<br><br>Source: http://www.oxfordlearnersdictionaries.com/definition/english/should?q=should
”插入数据存储区
但是在检索数据时,System.out.println(description);
return <Text: We should arrive before dark.<br>I should have finished the book by Fr...>
(部分数据丢失&数据头部有<Text:
&...
在数据的尾部)&这把一切都搞砸了。
那么,如何从数据存储 Google 云中检索文本类型?
您需要调用getValue()
方法。如果将 Text
对象传递给 println()
,它将调用 toString()
方法。 Here are the Javadocs
