Grails, 레코드를 검색 할 때 캐스팅 오류가 발생했습니다.

Question

새 도메인을 만들고 수동으로 테이블을 만들었습니다. 테이블에 레코드가 하나만 있어야 레코드 ID가 (1)이됩니다.

레코드가 없으면 자동으로 만들어야하지만 레코드를 검색 할 때 항상 캐스팅 오류가 발생합니다. 수동으로 레코드를 수동으로 작성하면 get, find 또는 항상 오류가 반환되는 것은 중요하지 않습니다. 실패

코드 :

def int id = 1 
    def WtStatus wts = WtStatus.get(id)?:new WtStatus(id:1).save(failOnError:true) 

도메인 :

class WtStatus { 
    def prodBufferService 
    int  weekUpdated 
    Date dateUpdated 

    def beforeInsert() { 
     dateUpdated = new Date() 
     weekUpdated = prodBufferService.getCurrentYearWeek() 
    } 
    def beforeUpdate() { 
     dateUpdated = new Date() 
    } 
    static constraints = { 
     dateUpdated  nullable:true 
     weekUpdated  nullable:true 
    } 

    static mapping = { 
     table 'wt_status' 
     version true 
     id    column: "id",    type:  'int' 
    } 

}

테이블의 생성 스크립트 :

CREATE TABLE [dbo].[wt_status](
    [id] [int] NOT NULL, 
    [version] [bigint] NOT NULL, 
    [date_updated] [datetime2](7) NULL, 
    [week_updated] [int] NULL, 
CONSTRAINT [PK__wt_statu__3213E83F77809FC6] PRIMARY KEY CLUSTERED 
(
    [id] ASC 
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
) ON [PRIMARY]

Answer 1

ìd 변수에 사용하려는 유형이 int입니다. 도메인에 id 속성을 선언하지 않았으므로 Long (Grails 기본값)이됩니다. 참고 : 매핑 블록에서는 데이터베이스와의 관계 만 정의하므로 도메인의 속성은 여전히 ​​Long입니다.

또한 변수에 다른 유형을 사용하려는 경우 def을 사용할 필요가 없습니다. 이것을 시도하십시오 :

Long id = 1 
WtStatus wts = WtStatus.get(id)?:new WtStatus(id:1).save(failOnError:true) 

Answer 2

너무 복잡해 보입니다. 나는 당신이 정말 원하는 것은 생각 :

WtStatus wts = WtStatus.findOrSaveById(id) 

또한 ref-doc

에 따라, 당신은 Integer 유형이어야하는 id 필드를 정의 explicitelt한다. 그렇지 않으면 GORM은 기본값으로 Long으로 취급합니다.
