自定义存储库中的 PropertyReferenceException

João 发表于 Dev

若昂

我的项目有问题，该项目有多个数据源，我需要创建此方法来接收 DTO 并使用 Criteria 安装特定的 jpql。所以我犯了以下错误，已经尝试了一切，有人可以指点一下吗？

自定义界面

public interface LogRepositoryCustom {

    List<Log> filtrar();

}

自定义实现

@Transactional("dwhTransactionManager")
public class LogRepositoryCustomImpl implements LogRepositoryCustom {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    @Transactional("dwhTransactionManager")
    public List<Log> filtrar() {
        List<Log> logs = new ArrayList<>();
//        adicionarFiltro(filtro).list().forEach(l -> logs.add((Log)l));
//        adicionarFiltro(filtro).list();
        return logs;
    }

    private Criteria adicionarFiltro(LogFilter filtro) {
        Criteria criteria = entityManager.unwrap(Session.class).createCriteria(Log.class);

        if(filtro != null) {

            if(!StringUtils.isEmpty(filtro.getTipo()))
                criteria.add(Restrictions.eq("logtip", filtro.getTipo()));

            if(filtro.getData() != null) {
                criteria.add(
                        //data >= X
                        Restrictions.ge("logdateve", LocalDateTime.of(
                                filtro.getData().getYear(),
                                filtro.getData().getMonth(),
                                filtro.getData().getDayOfMonth(),
                                0, 0, 0)
                        )
                );

                criteria.add(
                        // data < X
                        Restrictions.lt("logdateve", LocalDateTime.of(
                                filtro.getData().getYear(),
                                filtro.getData().getMonth(),
                                filtro.getData().getDayOfMonth(),
                                0, 0, 0)
                        )
                );
            }

        }

        return criteria;
    }
}

存储库

@Repository
@Transactional("dwhTransactionManager")
public interface LogRepository extends JpaRepository<Log, Long>, LogRepositoryCustom {

    List<Log> findByLogsisOrderByLogdateveDesc(String logsis);

    List<Log> findByLogdateveOrderByLogdateveDesc(LocalDateTime logdateve);

    List<Log> findByLogdateveBetweenOrderByLogdateveDesc(LocalDateTime de, LocalDateTime ate);
}

日志类

@Entity
public class Log implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long logid;
    @Column(nullable = false)
    private LocalDateTime logdateve;
    @Column(nullable = false)
    private String logtip;
    @Column(nullable = false)
    private String logsis;
    @Column(nullable = false)
    private String logdes;
    private String logobs;
    private String logpro;

 /* Get Set*/
}

您的自定义实现需要与您的存储库具有相同的名称 +Impl所以它应该被命名LogRepositoryImpl

它需要实际包含自定义方法的实现（具有相同名称、参数和返回类型的方法）。所以在这种情况下，它应该有一个方法List<Log> filtrar(){ ... }
