MongoDB autowire抛出异常

Question

我有下面的类文件，它看起来一切正常，但我不明白为什么我得到autowire失败。任何人都可以请帮我找到问题吗？

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.da.repository.PersonRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=personRepository)}

它是我不好：

与包装细节

package com.ui.controller; 

    @RestController 
    @RequestMapping(value = "/Person") 
    public class PersonController { 

     @Autowired 
     @Lazy 
     private RepoService repoService; 

    } 

    package com.messaging.service.impl; 
    @Component 
    @Lazy 
    public class RepoServiceImpl implements RepoService { 

     @Autowired 
     @Qualifier("personRepository") 
     private PersonRepository personRepo; 

    } 

    package com.messaging.service; 
    public interface RepoService { 

    } 


    package com.da.repository; 
    @Repository("personRepository") 
    public interface PersonRepository extends MongoRepository<SomeType, String> { 
    } 


    package com.conf; 
    @Configuration 
    @EnableMongoRepositories(basePackages = "com.da.repository") 
    @EnableMongoAuditing 
    @Profile("mongo") 
    public class MongoConfig extends AbstractMongoConfiguration { 

    } 

我收到以下错误更新。问题不在于上述编码，而是与mongodb连接。有一个连接问题导致了上述错误。
