- 实体类

  ```java
  @Setter
  @Getter
  public class Profiles {
  	
  	@Id
  	private String id;
  	private String title;
  	private List<Pdn> pdn;
  	private Link ambr;
  	private Security security;
  
  }
  ```

  

- Repository类

  ![2](../mongo2.png)

  ```java
  @Repository
  public interface ProfilesRepository extends MongoRepository<Profiles, String> {
  
  	Profiles findByTitle(String title);
  
  	@Query(value = "{'_id':{'$ne':null}}", fields = "{'title':1,'_id':0}")
  	List<Profiles> title();
  
  }
  ```

- Repository的使用

  ```java
  @Service
  public class ProfileService {
  	@Autowired
  	private ProfilesRepository profileRepository;
  
  	public Page<Profiles> find(Profiles exp, BasePageParam pageParam) {
  		Integer page = pageParam.getPage();
  		if (page == null || page < 1) {
  			page = 1;
  		}
  		Integer size = pageParam.getSize();
  		if (size == null || size == 0) {
  			size = 20;
  		}
  		PageRequest pageable = PageRequest.of(page - 1, size, Direction.DESC, "_id");
  		ExampleMatcher matcher = ExampleMatcher.matching().withIgnorePaths("_class").withMatcher("title", GenericPropertyMatcher.of(StringMatcher.CONTAINING));
  		Example<Profiles> example = Example.of(exp, matcher);
  		return profileRepository.findAll(example, pageable);
  	}
  
  	public Profiles findByTitle(String title) {
  		return profileRepository.findByTitle(title);
  	}
  
  	public List<Profiles> findTitles() {
  		return profileRepository.title();
  	}
  
  	public void save(Profiles profiles) throws SprtException {
  		Profiles old = profileRepository.findByTitle(profiles.getTitle());
  		if (old != null) {
  			throw new SprtException("已存在相同名称的模板");
  		}
  		profileRepository.save(profiles);
  	}
  
  	public void update(Profiles profiles) throws SprtException {
  		profileRepository.save(profiles);
  	}
  
  	public void delete(Profiles profiles) {
  		profileRepository.deleteById(profiles.getId());
  	}
  
  }
  
  ```
