Nedeniyle: org.springframework.data.mapping.model.MappingException: com.common.model.EmployeeTerritory üzerinde hiçbir özellik territoryID bulunamadı! - İlkbahar Çizme

Question

Spring Boot MongoDB örneğini geliştiriyorum. Bu örnekte, spring-data-mongo deposu sorgusuyla TerritoryID'yi almaya çalışıyorum ve aşağıdaki hataya bakıyorum. EmployeeTerritory.java

@Document(collection="employee-territories") 
public class EmployeeTerritory { 

    @Id 
    private ObjectId id; 
    @Field 
    private String EmployeeID; 
    @Field(value="TerritoryID") 
    private Integer TerritoryID; 
    // setters and getters 
} 

EmployeeTerritoryRepository.java

public interface EmployeeTerritoryRepository extends CrudRepository<EmployeeTerritory, String>{ 
    EmployeeTerritory findByTerritoryID(Integer territoryID); 
} 

EmployeeTerritoryService.java

public interface EmployeeTerritoryService { 
    EmployeeTerritory findByTerritoryID(Integer territoryID); 
} 

:

Ben geliştirilen kod rehberlik edin

EmployeeTerritoryServiceImpl.java

@Component 
public class EmployeeTerritoryServiceImpl implements EmployeeTerritoryService{ 

    @Autowired 
    private EmployeeTerritoryRepository employeeTerritoryRepository; 


    @Override 
    public EmployeeTerritory findByTerritoryID(Integer territoryID) { 
     EmployeeTerritory et = employeeTerritoryRepository.findByTerritoryID(territoryID); 
     return et; 
    } 
} 

MainController.java

@Controller 
public class MainController implements CommandLineRunner { 
    private Logger LOGGER = Logger.getLogger(MainController.class); 

    @Autowired 
    private EmployeeTerritoryService etService; 

    @Override 
    public void run(String... args) throws Exception { 
     LOGGER.info("~~ STARTED ~~"); 
     // Find employee-territories 
     EmployeeTerritory et = etService.findByTerritoryID(19713); 
     LOGGER.info("~~~~~~~~~~~~~~~~~~~~~~~~"); 
     LOGGER.info("EmployeeID : "+et.getEmployeeID()); 
     LOGGER.info("TerritoryID : "+et.getTerritoryID());

DB Koleksiyonu:

Answer 1

Bu hataları çözdüm. Lütfen aşağıdaki kod snippet'ime bakın. Yayınlanan veriler mongo docs başı olarak (Bkz. Bölüm 12.1.1): http://docs.spring.io/spring-data/mongodb/docs/current/reference/html/

Mongo DB alanlarınız deve harflerini ve ilgili ayarlayıcı ve alıcıları kullanıyor, ancak dokümanlardaki gibi "Tanımlayıcılar için varsayılan alan adı" _id "dir. ve @Field ek açıklaması yoluyla özelleştirilebilir. "

For Ex: @Field('x') String id 


Resulting Id-Fieldname in MongoDB ==> x, 

Benzer mantık size herhangi bir alan (lar) tarafından veri almak çekinmiyorsanız tüm alanı için uygulamak gerekir.

Aşağıdakileri kullanın ve çalışacaktır.

@Document(collection="employee-territories") 
public class EmployeeTerritory { 

    @Id 
    private ObjectId id; 
    @Field("EmployeeID") 
    private Integer employeeID; 
    @Field("TerritoryID") 
    private Integer territoryID; 

    public ObjectId getId() { 
     return id; 
    } 
    public void setId(ObjectId id) { 
     this.id = id; 
    } 
    public Integer getEmployeeID() { 
     return employeeID; 
    } 
    public void setEmployeeID(Integer employeeID) { 
     this.employeeID = employeeID; 
    } 
    public Integer getTerritoryID() { 
     return territoryID; 
    } 
    public void setTerritoryID(Integer territoryID) { 
     this.territoryID = territoryID; 
    } 
} 

Answer 2

Sadece açıklama amacıyla. Bunun kesin bir cevap olduğunu iddia etmiyorum. Belki beni yanlış anladınız demektir. Fasulye için java adlandırma kurallarına saygı göstermelisiniz.

@Document(collection="employee-territories") 
    public class EmployeeTerritory { 

    @Id 
    private ObjectId id; 
    @Field 
    private String EmployeeID; 
    @Field(value="TerritoryID") 
    private Integer TerritoryID; 
    // setters and getters 
} 

@Document(collection="employee-territories") 
public class EmployeeTerritory { 

    @Id 
    private ObjectId id; 
    @Field 
    private String employeeID; 
    @Field(value="TerritoryID") 
    private Integer territoryID; 
    // setters and getters 
} 

O may, tekrar ediyorum, bu istisna sebebi olabilir olmalıdır.
