저는 봄 mvc 프로젝트를 시작했고 거기에서 JPA를 사용하려고했습니다. @RooJavaBean에 의해 생성 된 접근자를 사용하여 클래스 User 및 BasePersistable을가집니다.RooJavaBean 메서드 getId()가 추상 메서드 Persistable.getId()를 재정의하지 않습니다.
import javax.persistence.GeneratedValue;
import javax.persistence.MappedSuperclass;
import javax.persistence.Version;
import org.springframework.data.annotation.Id;
import org.springframework.data.domain.Persistable;
import org.springframework.roo.addon.javabean.RooJavaBean;
@RooJavaBean
@MappedSuperclass
public abstract class BasePersistable implements Persistable<Long> {
private static final long serialVersionUID = -3281161320810540373L;
@Id
@GeneratedValue
private Long id;
@Version
private Integer version;
@Override
public boolean isNew() {
return getId() == null;
}
}
및
@Entity
@RooJavaBean
public class User extends BasePersistable {
private static final long serialVersionUID = -1999311284585286126L;
private String username;
private String passwrd;
private String firstname;
private String lastname;
private String email;
@Temporal(TemporalType.TIMESTAMP)
private Calendar signupDate;
private Sex sex;
private String comment;
}
루는 확실히 getter 및 setter를 생성합니다. 내가 코드 getId() 메서드에 액세스 할 수 있습니다 :
User user = new User();
user.getId();
하지만이 오류가 발생했습니다 :

그것은 내가 생각 AspectJ를 몇 가지 문제가있는 것 같다. 누구든지 도와 줄 수 있습니까?
public Long getId() {
return 1L;
}
UPD 2 께 : 사용자 클래스 스터브 방법 getId()를 추가 할 경우에는 여기 UPD
그렇고 BasePersistable_Roo_JavaBean.aj

인 나는 프로젝트가 무엇이 잘못되었는지 상상할 수 없다. pom 파일에 새로운 의존성을 추가하고 maven이 그것을 다운로드하지 않습니다. 여기 내 치어는 다음과 같습니다

내 서블릿 컨텍스트입니다! 문제는 일부 종속성 또는 플러그인의 버전 충돌입니다.
에 대한 배치하려고 할 수있는 것은 BasePersistable_Roo_JavaBean.aj cantain 방법 getId()
이다; 사용자는 BasePersistable에서 상속되므로 id에 대한 getter도 있습니다. – malykhinvi
파일은 어디에 있습니까? 질문을 업데이트하십시오. – SiB
상속 (strategy = InheritanceType.TABLE_PER_CLASS)이 결과에 영향을 미치지 않았습니다. – malykhinvi
