之前我正在使用stackoverflow。很长一段时间我没有发表问题。我使用mongodb与spring mvc 4.0.3框架。我认为因为我的弹簧配置xml而出错。我关注this tutorial让我与您分享我的代码，以便您可以帮助我找出问题所在。感谢...
@Transactional
public interface IPersonService extends MongoRepository<Person, String>{
}
＆GT;
@Service
@Repository("personService")
public class UserService {
@Autowired
private IPersonService personService;
@Autowired
private MongoTemplate mongoTemplate;
public List<Person> getAllPersons() throws Exception{
return this.personService.findAll();
}
public Person findPersonById(String personId) throws Exception{
if(personId == null || personId.equals(""))
throw new Exception("wrong id");
Person person = mongoTemplate.findById(personId, Person.class);
if(person == null)
throw new Exception("user is not find");
return person;

public Person updatePerson(Person person) throws Exception{
Person dbPerson = findPersonById(person.getId());
if(dbPerson == null)
throw new Exception("xxx : update user failed");

答案 0 :(得分：0)
您是否添加了mongodb存储库扫描：
在applicationContext.xml添加XML架构和标记repositories进行扫描：
