java - 如何获取自定义元数据属性的值

Question

我正在尝试获取 DAM 中 Assets 的元数据。但是，对于前面没有“dc:”的属性，元数据似乎返回为空。

Resource rs = getResourceResolver().getResource(fileReference);
Asset asset = rs.adaptTo(Asset.class);
//this works
title = asset.getMetadataValue("dc:title").toString(); 
//this does not work. 
//I have ensured that "mine.title" is a property and has string value assigned to it. 
customTitle = asset.getMetadataValue("mine.title").toString(): 
//this does not work either
customTitle = asset.getMetadata("mine.title").toString(): 

有没有办法从自定义元数据属性中获取值？

最后的 Assets 是简单的节点，因此要获取某些属性，您可以执行以下操作(取决于变量 fileReference 的实际路径):

Resource metadataResource = rs.getChild("jcr:content/metadata");
ValueMap properties = ResourceUtil.getValueMap(metadataResource);
customTitle = properties.get("mine.title", "defaultValue")
