本文整理了Java中org.apache.sling.api.resource.Resource.getResourceMetadata方法的一些代码示例，展示了Resource.getResourceMetadata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.getResourceMetadata方法的具体详情如下：
包路径：org.apache.sling.api.resource.Resource
类名称：Resource
方法名：getResourceMetadata

Resource.getResourceMetadata介绍

[英]Returns the meta data of this resource. The concrete data contained in the ResourceMetadata object returned is implementation specific except for the ResourceMetadata#RESOLUTION_PATH property which is required to be set to the part of the request URI used to resolve the resource.
[中]返回此资源的元数据。返回的ResourceMetadata对象中包含的具体数据是特定于实现的，ResourceMetadata#RESOLUTION_PATH属性除外，该属性需要设置为用于解析资源的请求URI的一部分。
