Why the path returns doesn't return the correct one as specified in applicaiton.properties?

[tangara goh]

Hi experts,

I have been trying many days to get the image to be inserted into a path that I specified in the application.properties but to no avail.

And I am not sure where I had done wrongly such that when I printed out the path it would not include the the last / and so the image will not get into the folder but append to the last part of the path and not after the /

@ConfigurationProperties(prefix = "uploadfile")
@Configuration
public class FileStorageProperties {
	
	
	private String uploadDir;
	private String fileName;

	@Autowired
	FileStorageProperties(@Value("${uploadfile.uploadDir}")String uploadDir){
		this.uploadDir = uploadDir;	
		System.out.print("====" + uploadDir + "======");  // this will print out correctly
	}
	
	@Value("${uploadfile.uploadDir}")
    public String getUploadDir() {
        return uploadDir;
    }

    public void setUploadDir(String uploadDir) {
        this.uploadDir = uploadDir;
    }

public class Controller{

@Value(value = "uploadfile.uploadDir") 
	private String uploadDir;

		
	@Autowired
	FileStorageProperties fs;
	


					Path Location = Paths.get(fs.getUploadDir());

			        logger.info("file path: {}", fs.getFilePath() + fs.getUploadDir(), null);
					System.out.println("Path locatin :" + Location);
					
				
					String path2 = Location.toString();
					
					
					//Path path = Paths.get(uploadDir);// +  file.getOriginalFilename()); // doesn't work
					Path path = Paths.get(path2, "/");
					Path write = Files.write(path, bytes);
					System.out.print("path" + path.toString());
					System.out.print("write" + write.toString());

Here's the applicaiton.properties:

uploadfile.uploadDir=C:\User\abc\foldername\
uploadfile.upload-extension=jpg,jpeg,gif,png,PNG,JPEG

To be more clear,

my path is C:\User\abc\foldername\

So for the calss FileStorageProperties it will give me the exact path as put in the application.properties

but when I print out the controller it will just print C:\User\abc\foldername and the image name will append right after foldername

I am exhausted and I am beaten.

I am not sure what to do now and it is like nobody can help me cos everyone said all the answers are in the internet but really I have tried so hard I still can't get it right.

Please help me.

Tks.

It could be caused by the properties parsing that uses \ as an escape character.

It the only issue is that the directory is missing a trailing \, then the solution is actually quite simple. Don't use string concatenation, use Path.resolve:

Path path = Paths.get(uploadDir).resolve(file.getOriginalFilename());

Hi Rob,

Thanks.

I'd like to know if this code is used in the cloud ... I mean if the app is being hosted on the cloud and say if I changed the C:\ blah blah blah to a location in the db in the cloud, will it work or I need to take note of further configuration and the API being used.

What are those ?

With the resolve method, it will resolve the file relative to the path. Windows supports both \ and / for directory separators, Linux only /. As long as you don't have any \ in the path to resolve, the method should do the same on both Windows and Linux.

How about using c:\\User\\abc\\foldername\\ in application.properties?
