报错：One To Many属性类型不能为EmploymentDetails（Hibernate+Lombok）

核心问题 #

EmploymentDetails类缺少Hibernate持久化实体必需的@Entity注解。Hibernate要求@OneToMany注解关联的目标类型必须是被@Entity标记的实体类，否则会将其识别为非持久化类型，触发该错误提示。

验证与修正 #

查看你提供的EmploymentDetails代码，确实未添加@Entity注解，同时Hibernate实体类还需要无参构造函数（Lombok的@NoArgsConstructor可自动生成）。修正后的代码如下：

@lombok.Getter
@lombok.Setter
@Entity // 新增：标记为Hibernate实体类
@lombok.NoArgsConstructor // 新增：生成无参构造函数，满足Hibernate要求
public class EmploymentDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String jobTitle;
    private String employmentType;
    private String client;
    private String employer;
    //private LocalDate startDate;
    //private LocalDate endDate;
    private String location;
    private String jobDescription;
    private String jobDuties;
    private String technologyStack;

    public EmploymentDetails(
     String jobTitle,
     String employmentType,
     String client,
     String employer,
     String location,
     String jobDescription,
     String jobDuties,
     String technologyStack){
        this.jobTitle = jobTitle;
        this.employmentType = employmentType;
        this.client = client;
        this.employer = employer;
        this.location = location;
        this.jobDescription = jobDescription;
        this.jobDuties = jobDuties;
        this.technologyStack = technologyStack;
    }
}

额外建议 #

• 确保EmploymentDetails类所在包被Hibernate的组件扫描覆盖（通常Spring Boot主启动类同包或子包下会自动扫描）。
• 若需要双向关联，可在EmploymentDetails中添加@ManyToOne注解，配合@JoinColumn指定外键，示例：

@ManyToOne
@JoinColumn(name = "PORTFOLIO_ID")
private PortfolioDetails portfolioDetails;
