I had put Package name in component scan and @component also , but still error is coming . The code is below.
Here is the SpringConfig file:-
@Configuration
@ComponentScan(basePackages={"com.cagataygurturk.example.lambda","com.cagataygurturk.example.services"})
public class SpringConfig {
}
Here is the Service Class:-
@Component
public class Service {
/**
* Autowiring another Spring Bean
*/
@Autowired
AnotherService anotherService;
public String getText(String text) {
//return anotherService.getText(text);
return "hello";
}
}
Here is the AnotherService class which is autowired in service class:-
@Component
public class AnotherService {
@Autowired
IFileStoreService file;
public String getText(String text) {
String t;
t=(String)text;
if(t.equals("get"))
{
file.get("1");
return "You are in Get Controller and database is not connected\n";
}
else
if(t=="post")
{
return "You are in post Controller and databse is not connecte\n";
}
else
if(t=="delete")
{
return "You are int delete Controller and mongo database in not connected\n";
}
else
{
return "hii\n"+text+"hey";
}
}
}
Here is the IFileStoreService class autowired in AnotherService class:
public interface IFileStoreService {
Resource get(String id) throws StorageException, StorageFileNotFoundException;
}
Here is the IFileStoreImpl class:-
@Component
public class FileStoreServiceImpl implements IFileStoreService {
private static final Logger logger = LoggerFactory.getLogger(FileStoreServiceImpl.class);
@Autowired
private IFileStoreDAO fileStoreDAO;
@Autowired
private StorageProperties storageProperties;
@Override
public Resource get(String id) throws StorageException, StorageFileNotFoundException {
Resource resource = null;
File file = null;
try {
FileDetails fileDetails = fileStoreDAO.get(id);
if(fileDetails != null) {
String tempDir = storageProperties.getLocation();
file = new File(tempDir + File.separator + fileDetails.getName());
file.mkdirs();
if(file.exists()) {
// p1: delete any file if existent in the directory;
file.delete();
}
file.createNewFile();
FileCopyUtils.copy(fileDetails.getFileBytes(), file);
resource = new UrlResource(Paths.get(tempDir).resolve(fileDetails.getName()).toUri());
} else {
throw new StorageFileNotFoundException("No document found with id: " + id);
}
} catch (Exception e) {
logger.error(e.getMessage(), e);
if (e instanceof StorageFileNotFoundException) {
throw (StorageFileNotFoundException) e;
} else {
throw new StorageException("", e);
}
}
return resource;
}
}
And last MainHandler function:-
@SuppressWarnings("unused")
public class MainHandler
extends AbstractHandler<SpringConfig>
implements RequestHandler<Map<String,Object>, String> {
static final Logger log = Logger.getLogger(MainHandler.class);
@Override
public String handleRequest(Map<String, Object> input, Context context)throws RuntimeException {
// TODO Auto-generated method stub
Service businessService = getApplicationContext().getBean(Service.class);
return businessService.getText("hii");
}
}
and the Error is :-
{"errorMessage":"Error creating bean with name 'service': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.cagataygurturk.example.services.AnotherService com.cagataygurturk.example.services.Service.anotherService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'anotherService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.cagataygurturk.example.services.IFileStoreService com.cagataygurturk.example.services.AnotherService.file; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fileStoreServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.cagataygurturk.example.services.IFileStoreDAO com.cagataygurturk.example.services.FileStoreServiceImpl.fileStoreDAO; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.cagataygurturk.example.services.IFileStoreDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
