【问题描述】：

下面是我的视图实体vw_invoice_report

@Entity
@Table(name = "vw_invoice_report")
class Report implements Serializable 
    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "id")
    private Long id;

    @Column(name = "sender_name")
    private String sender;

    @Column(name = "client_name")
    private String client;

    @Column(name = "submit_date")
    @Temporal(TemporalType.TIMESTAMP)
    private Date submitDate;

    @Column(name = "invoice_num")
    private String invoiceNum;

    //getters
    

我正在尝试实现findByClientAndLawfirmAndSubmitDateBetween 以使用client,sender, submitDate 字段查询视图

public interface ReportRepository extends PagingAndSortingRepository<Report, Long>
   public List<Report> findByClientAndLawfirmAndSubmitDateBetween(String client, String sender, Date start, Date stop, Pageable pageable)

当我尝试调用上述方法时，出现以下错误

org.hibernate.QueryException: could not resolve property: client of: com.xyz.reports.Report 
[select generatedAlias0 from com.xyz.reports.Report as generatedAlias0 where ( ( generatedAlias0.client=:param0 ) and ( generatedAlias0.sender=:param1 ) ) and ( generatedAlias0.submitDate between :param2 and :param3 )]; nested exception is java.lang.IllegalArgumentException: org.hibernate.QueryException: could not resolve property: client of: com.xyz.reports.Report [select generatedAlias0 from com.xyz.reports.Report as generatedAlias0 where ( ( generatedAlias0.client=:param0 ) and ( generatedAlias0.sender=:param1 ) ) and ( generatedAlias0.submitDate between :param2 and :param3 )] 34178348919273527

但是，如果我用Query 注释将上面的查询注释为下面的工作正常

@Query(value="SELECT id, sender_name, client_name, submit_date, invoice_num FROM vw_invoice_report WHERE client_name  = ?1 AND  sender_name = ?2 AND submit_date BETWEEN ?3 AND ?4 ORDER BY submit_date desc",
        nativeQuery = true)`

有没有办法让findByClientAndLawfirmAndSubmitDateBetween() 在没有@Query 的情况下工作

【问题讨论】：

您的实体中的Lawfirm 在哪里？？

我的错，重构很糟糕，lawfirm 是Report 实体中的sender 字段

是不是导致异常？？？你解决了吗？？？

@RanPaul 您的PagingAndSortingRepository 的标识符类型是Integer，而@Id 属性是Long。你能检查一下这是否会导致问题吗？

@Daniel 我把它改成了Long 仍然面临这个问题

【参考方案1】：

要么

将属性 sender 重命名为 lawFirm

@Column(name = "sender_name")
private String lawfirm;

或

将您的存储库方法重命名为：

findByClientAndSenderAndSubmitDateBetween
