本文整理了Java中org.springframework.core.env.PropertySource.containsProperty()方法的一些代码示例，展示了PropertySource.containsProperty()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。PropertySource.containsProperty()方法的具体详情如下：
包路径：org.springframework.core.env.PropertySource
类名称：PropertySource
方法名：containsProperty

PropertySource.containsProperty介绍

[英]Return whether this PropertySource contains the given name.

This implementation simply checks for a null return value from #getProperty(String). Subclasses may wish to implement a more efficient algorithm if possible.
[中]返回此PropertySource是否包含给定名称。
这个实现只是检查#getProperty（String）的空返回值。如果可能的话，子类可能希望实现更高效的算法。
