我有一个至少包含 10 个字段的表。然而，在我的实体类中，我仅映射到三列。
例如:
表格列如下: 1. 身份证号码 2. 姓名 3. 员工代码 4. 类别 5. 能力 6. 特点 7. 电子邮件 8.FROM_DATE 9. 截止日期 10. 创建者
实体类如下:
@Entity
@Table(name = "Employee_not_available")
public class EmpNotAvailable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private Long id;
@Column(name = "EMP_CODE", unique = true)
private String empCode;
@Column(name = "FROM_DATE")
private Date fromDate;
@Column(name = "TO_DATE")
private Date toDate;
}
当我尝试执行 native 查询操作时，出现错误原因为:java.sql.SQLException:未找到列“CREATED_BY”。
我只能运行 native 查询，因为查询包含 DATE_ADD(CURDATE(), INTERVAL 7 DAY) 操作。
repo查询如下:
@Query(value = "select EU.ID, EU.EMP_CODE from Employee_not_available" +
" as EU JOIN EMPLOYEE as E ON EU.EMP_CODE = E.CODE " +
"JOIN EMPLOYEE_LEAVE EL ON EL.EMAIL = E.EMAIL " +
"where EL.END_DATE > DATE_ADD(CURDATE(), INTERVAL 7 DAY) AND EL.DAYS > 7",
nativeQuery = true)
任何指导都会对我非常有帮助。
堆栈跟踪如下:
Hibernate: select EU.ID, EU.EMP_CODE from EMPLOYEE_UN_ALLOCATABLE_DETAILS as EU JOIN EMPLOYEE as E ON EU.EMP_CODE = E.CODE JOIN EMPLOYEE_LEAVE EL ON EL.EMAIL = E.EMAIL where EL.END_DATE > DATE_ADD(CURDATE(), INTERVAL 7 DAY) AND EL.DAYS > 7

最佳答案
如果没有所有必要的数据，您就无法创建实体。
自 createdBy字段是从父类(super class)继承的，Hibernate会寻找CREATED_BY在结果集中。其他继承字段也是如此。
您应该在查询中包含这些列，因为这是最简单的事情。否则，您将不得不尝试使用 SELECT NULL AS CREATED_BY, .. 选择空值之类的方法。但如果这些在实体中不可为空，那么这不是一个好主意。
关于java - 如何为仅与所需列映射的实体选择特定列，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60411532/
