HIbernate 通过 JPA 检查约束名称

Question

考虑以下

@Entity
@Table
@Check(constraints = "A IS NOT NULL OR B IS NOT NULL")    
public class Model {

@Id
private Long id;

private A a;

private B b;

}

问题是我不知道如何命名 checkConstraint ？ 我想要的是 @Check(constraints = @Constraint("name"="CHK_CONST_1", "A IS NOT NULL OR B IS NOT NULL"))

Answer 1

我认为您应该使用@Column 和name 属性来指定列的名称。

@Entity
@Table
@Check(constraints = "COL_A IS NULL OR COL_B IS NOT NULL")    
public class Model {

   @Id
   private Long id;

   @Column(name = "COL_A")
   private A a;

   @Column(name = "COL_B")
   private B b;

}
