Hibernate实体字段camelcase，数据库下划线 [英] Hibernate entity fields camelcase, database underscore

问题描述

我有下划线的数据库字段。我在camelcase中有实体字段。

是否有某种东西，或许是我可以使用的默认实体列名称注释，与camelcase等价的注释？

>

例如，我有一个这样的实体：

  @Entity 
 public class AuthorisationEntity {
 
 @Column（name =non_recoverable）
 private BigDecimal nonRecoverable; 
 
 @Column（name =supplier_recoverable）
 private BigDecimal supplierRecoverable; 
 
 @Column（name =refund_amount）
私人BigDecimal refundAmount; 
 
} 
  

我梦寐以求：

  @Entity 
 @DatabaseIsUnderscoreAndThisAnnotationConvertsThemToCamelCaseByDefault 
 public class AuthorisationEntity {
 
 private BigDecimal nonRecoverable; 
 
 private BigDecimal supplierRecoverable; 
 
私人BigDecimal refundAmount; 
 
 
  

解决方案

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。

请参阅：

命名策略示例

第二个示例 a>

非常好的oracle命名策略 - 它将骆驼转换为下划线约定，等等

I have database fields in underscore. I have entity fields in camelcase. I can't change either of those.

Is there something, maybe a class level annotation I can use to default entity column name annotations to the camelcase equivalent?

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;

}

I dream of this:

@Entity
@DatabaseIsUnderscoreAndThisAnnotationConvertsThemToCamelCaseByDefault
public class AuthorisationEntity {

    private BigDecimal nonRecoverable;

    private BigDecimal supplierRecoverable;

    private BigDecimal refundAmount;

}

解决方案

You can use hibernate's naming strategy. Such naming strategy class describes how to generate database names for given java names.

See:

naming strategy example

second example

very good oracle naming strategy - it converts camel to underscore convention, and much more
