我試圖使用Spring MVC和Hibernate保存表單中的字段。但在這裏我得到一些例外，如下所示。表單包含兩個元素與類型文件..我找不到代碼中的任何錯誤。任何人都可以請幫我擺脫這個例外。在此先感謝....注入自動裝配依賴項失敗;嵌套異常是org.springframework.beans.factory.BeanCreationException：無法自動裝入字段：
這裏是我的控制器：
@Controller
@RequestMapping(value = "ecom")
public class MerchantController {
@Autowired
MerchantService merchantService;
@RequestMapping(value = "/saveMe", method = { RequestMethod.POST, RequestMethod.GET })
public ModelAndView saveMe(ModelMap model, HttpServletRequest req) throws FileUploadException {
System.out.println("inside controller");
String status = merchantService.saveAll(req);
model.put("status",status);
return new ModelAndView("merchantRegistration",model);
}
}
這是我ServiceImpl：
@Service("merService")
@Transactional
public class MerchantServiceImpl implements MerchantService {
@Autowired
MerchantDao merchantDao;
@Override
public String saveAll(HttpServletRequest req){
System.out.println("inside serv");
boolean isMultipart = ServletFileUpload.isMultipartContent(req);
boolean boolStatus=false;
byte[] bytes = null;
byte[] bytesTwo = null;
Merchant merchant = new Merchant();
if(isMultipart) {
try {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List<FileItem> items = upload.parseRequest(req);
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
String fieldName = item.getFieldName();
if (item.isFormField()) {
if (fieldName.equalsIgnoreCase("merchant-name")) {
merchant.setMerchantName(item.getString());
}else if (fieldName.equalsIgnoreCase("industry")) {
Industry industry = new Industry();
industry = merchantDao.getIndustry(Integer.parseInt(item.getString()));
merchant.setIndustry(industry);
} else if (fieldName.equalsIgnoreCase("cmpny-reg-no")) {
merchant.setMerchantNo(item.getString());
} else if (fieldName.equalsIgnoreCase("zakka-no")) {
merchant.setMerchantZakka(item.getString());
} else if (fieldName.equalsIgnoreCase("bank-id")) {
Bank bank = new Bank();
bank = merchantDao.getBank(Integer.parseInt(item.getString()));
merchant.setBankId(bank);
} else if (fieldName.equalsIgnoreCase("bank-acc-no")) {
merchant.setMerchantAccount(item.getString());
} else if (fieldName.equalsIgnoreCase("bank-code")) {
merchant.setMerchantIfsc(item.getString());
} else if (fieldName.equalsIgnoreCase("service")) {
Services services = new Services();
services = merchantDao.getService(Integer.parseInt(item.getString()));
merchant.setServiceId(services);
} else if (fieldName.equalsIgnoreCase("fb")) {
merchant.setSocialNtwrk1(item.getString());
} else if (fieldName.equalsIgnoreCase("gplus")) {
merchant.setSocialNtwrk2(item.getString());
} else if (fieldName.equalsIgnoreCase("twitter")) {
merchant.setSocialNtwrk3(item.getString());
} else if (fieldName.equalsIgnoreCase("flickr")) {
merchant.setSocialNtwrk4(item.getString());
}
merchant.setCreated(new Timestamp(new Date().getTime()));
} else {
try {
if (fieldName.equalsIgnoreCase("logo")) {
bytes = IOUtils.toByteArray(item.getInputStream());
String fileName1 = item.getName();
int indexOfFile1 = 0;
if (fileName1.contains("\\")) {
indexOfFile1 = fileName1.lastIndexOf("\\");
fileName1 = fileName1.substring(indexOfFile1 + 1);
//msg = msg + "With file "+fileName1;
}
merchant.setMerchantLogo(bytes);
} else if (fieldName.equalsIgnoreCase("banner")) {
bytesTwo = IOUtils.toByteArray(item.getInputStream());
String fileName2 = item.getName();
int indexOfFile2 = 0;
if (fileName2.contains("\\")) {
indexOfFile2 = fileName2.lastIndexOf("\\");
fileName2 = fileName2.substring(indexOfFile2 + 1);
//msg = msg + ", "+fileName2;
}
merchant.setMerchantBanner(bytesTwo);
}
} catch (IOException ex) {
//Logger.getLogger(ExceptionAndInvestigation.class.getName()).log(Level.SEVERE, null, ex);
// logger.error(ex);
}
}
}
} catch (FileUploadException ex) {
Logger.getLogger(MerchantServiceImpl.class.getName()).log(Level.SEVERE, null, ex);
}
boolStatus= merchantDao.saveInfo(merchant);
}
JSONObject jsonObj = new JSONObject();
if(boolStatus){
jsonObj.put("message","Saved Successfully");
jsonObj.put("status","success");
}else{
jsonObj.put("message","Save Failed");
jsonObj.put("status","fail");
}
return jsonObj.toString();
}
}
這是DaoImpl：
@Repository
public class MerchantDaoImpl implements MerchantDao {
@Autowired
private SessionFactory sessionFactory;
@Override
public boolean saveInfo(Merchant merchant){
boolean flag = false;
try {
System.out.println("Inside dao");
Session session = sessionFactory.getCurrentSession();
session.save(merchant);
flag = true;
} catch (Exception e) {
System.out.println("Exception in saving ..."+e.getMessage());
}
return flag;
}
@Override
public Industry getIndustry(int intIndustryId){
Session session = sessionFactory.getCurrentSession();
Industry industry = (Industry) session.get(Industry.class, intIndustryId);
return(Industry) industry;
}
@Override
public Bank getBank(int intBankId){
Session session = sessionFactory.getCurrentSession();
Bank bank = (Bank) session.get(Bank.class, intBankId);
return(Bank) bank;
}
public Services getService(int intServiceId){
Session session = sessionFactory.getCurrentSession();
Services service = (Services) session.get(Services.class, intServiceId);
return(Services) service;
}
我得到如下例外：
