文件路径(xxx/xxx/xx/xxx.xx)转二维数组(id,parent_id)

 

先整理所有文件夹

values = ["aaa/bb/dd.txt","aaa/bb/cc.txt","aaa/aa.txt"....]

 

//整理所有路径
Set<String> paths = new HashSet<>();
for (String path : values) {
    String[] split = path.split("/");
    String tmp = "";
    for (int i = 0; i < split.length - 1; i++) {
        tmp += split[i] + "/";
        paths.add(tmp);
    }
}

//整理文件夹路径，文件夹节点的Map
Map<String, FileSystemEntity> pathNodeMap = new HashMap<>();
for (String path : paths) {
    if (!pathNodeMap.containsKey(path)) {
        String[] split = path.split("/");
        if (split.length == 1) {
            pathNodeMap.put(path, getFolderEntiy(GeneralUtility.getUUID(), parentId, split[0], fileUserName));
        } else {
            String parentNodeId = null;
            String pathTmp = "";
            for (int i = 0; i < split.length; i++) {
                pathTmp += split[i] + "/";
                if (parentNodeId == null) {
                    if (pathNodeMap.containsKey(pathTmp)) {
                        parentNodeId = pathNodeMap.get(pathTmp).getId();
                    } else {
                        String uuid = GeneralUtility.getUUID();
                        pathNodeMap.put(pathTmp, getFolderEntiy(uuid, parentId, split[i], fileUserName));
                        parentNodeId = uuid;
                    }
                } else {
                    if (pathNodeMap.containsKey(pathTmp)) {
                        FileSystemEntity fileNode = pathNodeMap.get(pathTmp);
                        fileNode.setParentId(parentNodeId);
                        pathNodeMap.put(pathTmp, fileNode);
                        parentNodeId = fileNode.getId();
                    } else {
                        String uuid = GeneralUtility.getUUID();
                        pathNodeMap.put(pathTmp, getFolderEntiy(uuid, parentNodeId, split[i], fileUserName));
                        parentNodeId = uuid;
                    }
                }
            }
        }
    }
}

 

遍历所有文件，通过路径判断在哪个文件夹下。
