自动装配的MongoRepository实现在应用程序启动时抛出BeanCreationException

Question

我想使用MongoRepository接口,但我有一个BeanCreationException异常.ComponentScan和MappingBasePackage字符串已正确填充.

这是我的代码:

(Jersey类)@Component @Path("技能")公共类SkillREST {

    @Autowired
    private UserService userService;    

    @POST
    @Path("/{token}")
    @Produces({MediaType.APPLICATION_JSON})
    public List<Skill> addSkill(@PathParam("token") String token, Skill skill){
        return userService.getAllSkills();
    }
}

以下是未正确自动装配存储库的服务:

@Component
public class UserService {
    @Autowired
    SkillRepository skillRepository;

    public List<Skill> getAllSkills(){
        return skillRepository.findAll();
    }
}


@Repository
public interface SkillRepository extends MongoRepository<Skill, String> {
}

Spring配置类:

@Configuration
@PropertySource("classpath:mongodb.properties")
@EnableMongoRepositories
@ComponentScan("com.headlezz")
public class SpringMongoConfig extends AbstractMongoConfiguration {
    @Inject
    Environment environment;
    @Override
    public String getDatabaseName() {
        return environment.getProperty("db.name");
    }

    @Override
    @Bean
    public Mongo mongo() throws Exception {
        return new MongoClient("127.0.0.1");
    }

    @Override
    protected String getMappingBasePackage() {
        return "com.headlezz.repository";
    }

}

这是输出:

2014-11-14 17:00:49.693:WARN::Failed startup of context org.mortbay.jetty.plugin.Jetty6PluginWebAppContext@73f89d76{/nonamer,/home/pooh/workspace/java/nonamer/src/main/webapp}

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:293)...

有人能解释为什么会这样吗？

您应该明确指定存储库所在的包.添加

@EnableMongoRepositories(basePackages="com.headlezz.repository")

要么

@EnableMongoRepositories("com.headlezz.repository")

应该做的伎俩.
