I'm walking through a pivotal 'guide' project, my first time uploading files in Spring.
I've implemented the code exactly as the guide specifies but still am getting the following error:
Parameter 0 of constructor in hello.storage.FileSystemStorageService required a bean of type 'hello.storage.StorageProperties' that could not be found. Consider defining a bean of type 'hello.storage.StorageProperties' in your configuration. I've reviewed many so posts and it seems the common thread is to move my 'application' class to the root package, but its already there. Here is my project: UploadingFiles1Application.java
package hello; // multiple imports @SpringBootApplication public class UploadingFiles1Application { public static void main(String[] args) { SpringApplication.run(UploadingFiles1Application.class, args); } @Bean CommandLineRunner init(StorageService storageService) { return (args) -> { storageService.deleteAll(); storageService.init(); }; } } And here's my Service:
package hello.storage; import org.springframework.core.io.Resource; import org.springframework.web.multipart.MultipartFile; import java.nio.file.Path; import java.util.stream.Stream; public interface StorageService { void init(); void store(MultipartFile file); Stream<Path> loadAll(); Path load(String filename); Resource loadAsResource(String filename); void deleteAll(); } And its implementation:
package hello.storage; import java.io.IOException; import java.io.InputStream; import java.net.MalformedURLException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.nio.file.StandardCopyOption; import java.util.stream.Stream; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.io.Resource; import org.springframework.core.io.UrlResource; import org.springframework.stereotype.Service; import org.springframework.util.FileSystemUtils; import org.springframework.util.StringUtils; import org.springframework.web.multipart.MultipartFile; @Service public class FileSystemStorageService implements StorageService { private final Path rootLocation; @Autowired public FileSystemStorageService(StorageProperties properties) { this.rootLocation = Paths.get(properties.getLocation()); } @Override public void store(MultipartFile file) { String filename = StringUtils.cleanPath(file.getOriginalFilename()); try { if (file.isEmpty()) { throw new StorageException("Failed to store empty file " + filename); } if (filename.contains("..")) { // This is a security check throw new StorageException( "Cannot store file with relative path outside current directory " + filename); } try (InputStream inputStream = file.getInputStream()) { Files.copy(inputStream, this.rootLocation.resolve(filename), StandardCopyOption.REPLACE_EXISTING); } } catch (IOException e) { throw new StorageException("Failed to store file " + filename, e); } } @Override public Stream<Path> loadAll() { try { return Files.walk(this.rootLocation, 1) .filter(path -> !path.equals(this.rootLocation)) .map(this.rootLocation::relativize); } catch (IOException e) { throw new StorageException("Failed to read stored files", e); } } @Override public Path load(String filename) { return rootLocation.resolve(filename); } @Override public Resource loadAsResource(String filename) { try { Path file = load(filename); Resource resource = new UrlResource(file.toUri()); if (resource.exists() || resource.isReadable()) { return resource; } else { throw new StorageFileNotFoundException( "Could not read file: " + filename); } } catch (MalformedURLException e) { throw new StorageFileNotFoundException("Could not read file: " + filename, e); } } @Override public void deleteAll() { FileSystemUtils.deleteRecursively(rootLocation.toFile()); } @Override public void init() { try { Files.createDirectories(rootLocation); } catch (IOException e) { throw new StorageException("Could not initialize storage", e); } } } What am I missing?? Thanks in advance.
StoragePropertiesclass?
