Parameter 0 of constructor required a bean of type 'FileStoragePropertiesAedImages'

I have been on stack in several threads regarding this question although I still can not figure it out.

Parameter 0 of constructor in com.aed.demo.fileupload.FileStorageServiceAedImages required a bean of type 'com.aed.demo.fileupload.FileStoragePropertiesAedImages' that could not be found.

Action:

Consider defining a bean of type 'com.aed.demo.fileupload.FileStoragePropertiesAedImages' in your configuration.

I have created a FileStorageService and a FileStorageProperties files

File Storage Properties

@ConfigurationProperties(prefix = "file")
public class FileStorageProperties {
    private String uploadDir;

    public String getUploadDir() {
        return uploadDir;
    }

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

File Storage Service

@Service
public class FileStorageService {

    private final Path fileStorageLocation;

    @Autowired
    public FileStorageService(FileStorageProperties fileStorageProperties) {
    	
    	
        this.fileStorageLocation = Paths.get(fileStorageProperties.getUploadDir())
                .toAbsolutePath().normalize();

        try {
            Files.createDirectories(this.fileStorageLocation);
        } catch (Exception ex) {
            throw new FileStorageException("Could not create the directory where the uploaded files will be stored.", ex);
        }
    }

   ...
}

the above set up works like a charm and creates the directory file.upload-dir=home/.. that it's defined in the application.properties

I tried duplicating these two configurations with another file upload directory in application.properties

Second FileStorageProperties Class

@ConfigurationProperties(prefix = "aed")
public class FileStoragePropertiesAedImages {
    private String uploadDir;

    public String getUploadDir() {
        return uploadDir;
    }

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

Second FileStorageService

@Service
public class FileStorageServiceAedImages {
    private final Path fileStorageLocation;

    @Autowired
    public FileStorageServiceAedImages(FileStoragePropertiesAedImages fileStoragePropertiesAED) {
        this.fileStorageLocation = Paths.get(fileStoragePropertiesAED.getUploadDir())
                .toAbsolutePath().normalize();

        try {
            Files.createDirectories(this.fileStorageLocation);
        } catch (Exception ex) {
            throw new FileStorageException("Could not create the directory where the uploaded files will be stored.", ex);
        }
    }
   ...
}

and then the above error is thrown. I need to create 3 directories that I've defined like so in application.properties

file.upload-dir=home/..
mobile.upload-dir=mobile/..
aed.upload-dir=aed/..

prefixes are correct, why the second storage service can not be initialized and requires a bean type and the first one does not?

what you are doing is constructor autowiring at FileStorageServiceAedImages which requires bean of type FileStoragePropertiesAedImages but you have not defined bean of the type. You just added @ ConfigurationProperties to the FileStorageProperties. Adding @Configuration to FileStorageProperties will create the bean you required at FileStoragePropertiesAedImages.

Add @Configuation annotation to FileStoragePropertiesAedImages class should solve the problem.

@ConfigurationProperties(prefix = "aed")
@Configuation
public class FileStoragePropertiesAedImages {
