如何为两种不同列组合在实体类上添加唯一约束

@Entity
@Table(name = "your_table_name")
public class YourEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(nullable = false)
    private String column1;

    @Column(nullable = false)
    private String column2;

    // 添加联合唯一约束
    @Table(uniqueConstraints = {
            @UniqueConstraint(columnNames = {"column1", "column2"})
    })
    public class YourEntity {
        // 省略其他属性和方法
    }
}
