spring-mongo-data服务的spring配置

Question

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");
        return personService.save(person);
    }
}

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：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:mongo="http://www.springframework.org/schema/data/mongo"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/data/mongo
    http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">

  <mongo:mongo id="mongo" />

  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg ref="mongo" />
    <constructor-arg value="databaseName" />
  </bean>

  <mongo:repositories base-package="com.acme.*.repositories" />

</beans>

spring data mongodb project。
