自定义存储库中的 PropertyReferenceException

【问题标题】：PropertyReferenceException in Custom Repository自定义存储库中的 PropertyReferenceException
【发布时间】：2017-09-02 01:59:56
【问题描述】：

我的项目有问题，这个项目有多个数据源，我需要创建这个方法来接收 DTO 并使用 Criteria 挂载特定的 jpql。 所以报了下面的错误，已经试过了，有人能指点一下吗？

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*/
}

    【解决方案1】：

    你能把你的日志类放在这里吗？存储库类中的 findBy..() 方法将根据名称进行评估，并与模型类 (Log) 中的字段名称匹配。例如，如果您正在编写像 findByDepartmentId 这样的 findBy 方法，那么您的模型类中应该有一个名为 departmentId 的字段。
    重新检查您的 Log 类

    将您的类 LogRepositoryCustomImpl 重命名为 LogRepositoryImpl。那应该解决它。您的自定义存储库 impl 需要根据 spring-data 命名约定命名为 Impl。没有这个 spring-data 无法识别您的 impl 类，因此它会搜索您的 CustomRepository 接口中提到的名为 filtrar 的属性并抛出异常。

    【讨论】：

    • 将您的类 LogRepositoryCustomImpl 重命名为 LogRepositoryImpl。那应该可以解决它
    【解决方案2】：

    您的自定义实现需要与您的存储库具有相同的名称 + Impl 所以它应该被命名为 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&lt;Log&gt; filtrar(){ ... }

    【讨论】：

    • 这对我的理解来说真的很混乱。它是 LogRepositoryCustom 的实现，但我们必须将其命名为 LogRepositoryImpl..
