我遇到以下错误,错误提示该列在SECU
表中不存在。但是问题是我真的不需要此表中的该列,因为我只需要NONSECU
表中的该列,而该表仅在NONSECU
类中被引用。
在getbean方法或其他方法中有什么方法可以摆脱这种情况?

如果您想忽略某些字段的列映射,只需将其声明为Transient
赞:
@Entity
@Table(name = "SECU")
public class SECU implements Serializable {
@Transient
protected BigDecimal preTradLrgInScaleThrshld;
此字段将不会保留,并且在加载后始终为空值。
