如何在spring控制器中返回文件目录(源码树)

@Controller
public class FileController {

    @RequestMapping("/directory")
    @ResponseBody
    public List<Map<String, Object>> getDirectory() {
        String directoryPath = "/path/to/directory";
        File directory = new File(directoryPath);
        
        List<Map<String, Object>> fileList = new ArrayList<>();

        if (directory.exists() && directory.isDirectory()) {
            File[] files = directory.listFiles();
            
            for (File file : files) {
                Map<String, Object> fileInfo = new HashMap<>();
                fileInfo.put("name", file.getName());
                fileInfo.put("path", file.getAbsolutePath());
                fileInfo.put("isFile", file.isFile());
                fileList.add(fileInfo);
            }
        }
        
        return fileList;
    }
}
