Grails 3 - 특정 도메인 클래스로 인해 null 포인터 예외가 발생합니다.

Question

Grails 3을 사용해 본 장기 Grails 2 사용자. 새/빈 Grails 3 프로젝트를 만들었고 도메인 클래스를 하나씩 삭제하려고합니다. 어떤 이유로, 일부 도메인 클래스가 떨어지면 ("grails run-app"를 사용할 때) 응용 프로그램이 시작되지 않고 아래 표시된 null 포인터 예외가 발생합니다. 어떤 방법 으로든 문제에 대한 자세한 정보를 얻을 수 있습니까? 이미 stacktrace 출력을 시도했지만 더 이상 정보를 알려주지 않습니다. 이상한 점은 특정 도메인 클래스가 작동하지 않으며 일부 도메인이 작동하지 않는다는 것입니다. 일하는 사람이 일하지 않는 사람보다 "복잡하다". GORM에서 허용하는 "복합 키"매핑을 사용하여 내 모든 도메인 클래스를 ojdbc7.jar 사용하여 Java 8 B (102) Grails를 3.2.0 윈도우 10 Oracle 데이터베이스를 사용 :

정보.

그래서 특정 도메인 클래스를 삭제하고 응용 프로그램을 실행할 수 있습니다. 그리고 잘 실행되고 컨트롤러를 통해 데이터베이스에 데이터를 저장하기 위해 특정 도메인 클래스를 사용할 수도 있습니다. 그런 다음 나는 아래 클래스와 같은 특정 클래스를 실행 한 다음 run-app를 통해 앱을 시작하면 오류가 발생합니다. 그런 다음 특정 도메인 클래스를 제거하면 다시 작동하기 시작합니다. 그리고 "문제 도메인 클래스"는 다른 도메인 클래스보다 "단순합니다". 문제를 일으키는 도메인 클래스의 예 :이 내가 실행으로 얻을 오류 등등

물론이 같은 클래스가 동일한 데이터베이스에, 내 Grails의에이 응용 프로그램을 잘 작동

package aero.trax.inventory; 

import java.io.Serializable; 

class PnInventoryDetail implements Serializable { 

    Integer batch; 

    static mapping = { 
     table "PN_INVENTORY_DETAIL"; 
     version false; 
     id composite:['batch']; 

     columns { 
      batch column: "BATCH"; 
     } 
    } 
} 

그리고

Answer 1

복합 키는보다 일반적인 단일 열 키 대신 둘 이상의 속성/열로 구성된 키입니다. 이것은 복합 키가 아닙니다. 발전기 : '할당'하나를 가지고있는 도메인 클래스에 당신이 id 아닌 다른 열을 사용하려면, 그것을위한

id name: 'batch'
