异常：映射中的重复列 实体：列：哈希(应使用 insert= "false" update= "false" 进行映射)

Question

我对Hibernate框架非常陌生，在运行代码时遇到了一个异常：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.hibernate.SessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is org.hibernate.MappingException: Repeated column in mapping for entity: LeiRecord column: hash (should be mapped with insert="false" update="false")

我在SpringConfiguration、oracleDataDao的许多地方都遇到了这个错误，并且不理解代码在哪里出错，因为我没有在映射中定义重复列

您应该将类Address注释为@Embeddable，然后在addressLegal和addressHeadquearters的LeiRecord实体中引用其实例

@Embeddable
@Getter
@Setter
public class Address {
private String firstAddr;
private String nextAddr;
//... etc.
}
@Getter
@Data
@Entity
@Table(name = "BK_TEST")
@Immutable
public class LeiRecord {
// ...
@Embedded
@AttributeOverrides(
{
@AttributeOverride(name = "firstAddr",   column = @Column(name = "legalAddress_firstAddr")),
@AttributeOverride(name = "nextAddr",    column = @Column(name = "legalAddress_nextAddr")),
@AttributeOverride(name = "region",      column = @Column(name = "legalAddress_region")),
@AttributeOverride(name = "postalCode",  column = @Column(name = "legalAddress_postalCode")),
@AttributeOverride(name = "city",        column = @Column(name = "legalAddress_city")),
@AttributeOverride(name = "country",     column = @Column(name = "legalAddress_country")),
@AttributeOverride(name = "mailRouting", column = @Column(name = "legalAddress_mailRouting"))
}
)
private Address addressLegal;
@Embedded
@AttributeOverrides(
{
@AttributeOverride(name = "firstAddr",   column = @Column(name = "headquartersAddress_firstAddr")),
@AttributeOverride(name = "nextAddr",    column = @Column(name = "headquartersAddress_nextAddr")),
@AttributeOverride(name = "region",      column = @Column(name = "headquartersAddress_region")),
@AttributeOverride(name = "postalCode",  column = @Column(name = "headquartersAddress_postalCode")),
@AttributeOverride(name = "city",        column = @Column(name = "headquartersAddress_city")),
@AttributeOverride(name = "country",     column = @Column(name = "headquartersAddress_country")),
@AttributeOverride(name = "mailRouting", column = @Column(name = "headquartersAddr_mailRouting"))
}
)
private Address addressHeadquarters;
//... other entity fields
}
