public class User

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "IDENTITY_USER")
private Long identity;

推荐答案
Include 注释用于要包含在 equals 和 hashCode 方法。如果您想确切指定应使用的成员（而不是所有非静态非瞬态成员的默认值），则可以在选项卡中使用 onlyExplicitlyIncluded = true 选项 @EqualsAndHashCode 批注：
The Include annotation is used on the member(s) you want to include in the equals and hashCode methods. If you want to specify exactly which members should be used (instead of the default of all non-static non-transient members), you could use the onlyExplicitlyIncluded = true option in the @EqualsAndHashCode annotation:
@EqualsAndHashCode(onlyExplicitlyIncluded = true)
@Table(name = "USER")
public class User
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "IDENTITY_USER")
@EqualsAndHashCode.Include
private Long identity;
}
