我创建了一个简单的实体，但它给我错误，因为不是托管类型：.entity.Skus

实体类

package <path>.entity;

import jakarta.persistence.Column;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.Entity;

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@Entity(name = "skus")
public class Skus extends BaseEntity{
    @Column(name = "name")
    private String name;
}
