How to create directory structure using Java API?

upforsin

Hello

I'm trying to create a folder structure (something similar to "mkdir -p" command) using Java API, but when I create a folder, I cannot create a subfolder in it, because a parent folder does not exist yet.

How can I create a folder, commit transition, and then create a subfolder?

Considering you have root folder known, i would follow steps as (no external transaction handling needed):

1- Using the root folder name, get the path of the root folder.

2- Using the TMDQ as suggested, get the root folder node ref. 

3- If subfolder  (considering an input  are separated by multiple paths (like your mkdir -p case), you can split the path and iterate each subfolder and create subfolder within rootfolder and their sub folders.

3- If subfolder is not separated by path, you can directly create the subfoler within root folder.

Here is an example:

String folderPathQuery  = getFolderPathQuery(rootFolderName, siteShortName); //Change the query accordingly if not using sites
List<NodeRef> selectedNodes = searchService.selectNodes(nodeService.getRootNode(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE),
		folderPathQuery, null, namespaceService, false);
if (selectedNodes != null && !selectedNodes.isEmpty()) {
	NodeRef rootFolderRef = selectedNodes.get(0); 
	if(rootFolderRef != null && fileFolderService.exists(rootFolderRef)) {
		if(subFolderName.contains("/")) {
			String[] pathTokens = subFolderName.split("/");
			NodeRef subRootNodeRef = rootFolderRef;
			for (String subFolder : pathTokens) {
				subRootNodeRef = fileFolderService.create(subRootNodeRef, subFolder, ContentModel.TYPE_FOLDER).getNodeRef();
			}
		} else {
			fileFolderService.create(rootFolderRef, subFolderName, ContentModel.TYPE_FOLDER);
		}
	} else {
		// handle and notify message as needed. ROOT FOLDR NOT FOUND
	}
} else {
	// handle and notify message as needed.
}


private String getFolderPathQuery(String folderPath, String siteShortName) {
	StringBuilder queryBuilder = new StringBuilder("/app:company_home/st:sites/");
	queryBuilder.append("cm:").append(ISO9075.encode(siteShortName))
			.append("/cm:documentLibrary");
	if (null != folderPath && !folderPath.isEmpty()) {
		String[] pathTokens = folderPath.split("/");
		if (!"Document Library".equals(folderPath)) {
			for (String pathToken : pathTokens) {
				queryBuilder.append("/cm:").append(ISO9075.encode(pathToken));
			}
		}
	}
	return queryBuilder.toString();
}
