如何使用camelCase将Hibernate实体字段映射到snake_case(下划线)数据库标识符 [英] How to map Hibernate entity fields using camelCase to snake_case (underscore) database identifiers
问题描述
我在下划线中有数据库字段。我在camelcase中有实体字段。我不能改变其中任何一个。
I have database fields in underscore. I have entity fields in camelcase. I can't change either of those.
是否有一些东西,可能是一个类级别的注释我可以用来默认实体列名注释到camelcase等价物?
Is there something, maybe a class level annotation I can use to default entity column name annotations to the camelcase equivalent?
例如,我有这样的实体:
for example, I have an entity like this:
@Entity
public class AuthorisationEntity {
@Column(name = "non_recoverable")
private BigDecimal nonRecoverable;
@Column(name = "supplier_recoverable")
private BigDecimal supplierRecoverable;
@Column(name = "refund_amount")
private BigDecimal refundAmount;
}
我梦见这个:
@Entity
@DatabaseIsUnderscoreAndThisAnnotationConvertsThemToCamelCaseByDefault
public class AuthorisationEntity {
private BigDecimal nonRecoverable;
private BigDecimal supplierRecoverable;
private BigDecimal refundAmount;
}
推荐答案
你可以使用hibernate的命名策略。这种命名策略类描述了如何为给定的Java名称生成数据库名称。
You can use hibernate's naming strategy. Such naming strategy class describes how to generate database names for given java names.
请参阅:
非常好的oracle命名策略 - 它将camel转换为下划线约定,以及更多
very good oracle naming strategy - it converts camel to underscore convention, and much more
