Hibernate 5 @joinformula和@MapKeyTemporal

Question

我无法使用joinformula选择最后一个。这些地图工作正常，但使用连接公式显示了以下错误：

来自Instrumento的外键InstrumentoData的列数错误。应该是2

@MapKeyTemporal(TemporalType.DATE)
@MapKey(name = "dataMovimento")
@OneToMany(mappedBy = "instrumento")
@LazyCollection(LazyCollectionOption.EXTRA)
private final Map<Date, InstrumentoData> instrumentoData = new HashMap<>();

@ManyToOne(fetch = FetchType.LAZY)
@JoinFormula(value = "(SELECT i.ID_INSTRUMENTO FROM InstrumentoData i WHERE i.ID_INSTRUMENTO = id ORDER BY i.data_Movimento DESC LIMIT 1)")
private InstrumentoData ultimoInstrumentoData;

有人帮我吗？

Answer 1

@ManyToOne
@JoinColumnsOrFormulas({
        @JoinColumnOrFormula(column = @JoinColumn(name = "id", referencedColumnName = "ID_INSTRUMENTO")),
        @JoinColumnOrFormula(formula = @JoinFormula(value = "(SELECT i.data_Movimento FROM  Instrumento_Data i WHERE i.ID_INSTRUMENTO = id ORDER BY i.data_Movimento FETCH FIRST 1 ROWS ONLY)", referencedColumnName = "data_Movimento"))
})
private InstrumentoData ultimoInstrumentoData;
