本文整理了Java中com.hp.hpl.jena.rdf.model.Resource.getProperty方法的一些代码示例，展示了Resource.getProperty的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Resource.getProperty方法的具体详情如下：
包路径：com.hp.hpl.jena.rdf.model.Resource
类名称：Resource
方法名：getProperty

Resource.getProperty介绍

[英]Answer some statement (this, p, O) in the associated model. If there are several such statements, any one of them may be returned. If no such statements exist, null is returned - in this is differs from getRequiredProperty.
[中]回答相关模型中的一些陈述（this，p，O）。如果存在多个此类声明，则可以返回其中任何一个。如果不存在这样的语句，则返回null——这与getRequiredProperty不同。
