Java org.hibernate.AnnotationException:mdl.Complaint.jobDone中的未知映射项，引用的属性未知：mdl.jobDone.jobDone

我尝试使用hibernate创建一对一映射并保存SQL db，但在运行项目时遇到以下错误：

Initial SessionFactory creation failed.org.hibernate.AnnotationException: Unknown mappedBy in: mdl.Complaint.jobDone, referenced property unknown: mdl.JobDone.jobDone

其他类别：

@Entity
@Table(name = "JobDone", catalog = "jobcard", uniqueConstraints = {
        @UniqueConstraint(columnNames = "nature"),
        @UniqueConstraint(columnNames = "amount") })
public class JobDone implements Serializable{
    private Integer jobDone_id;
    private String nature;
    private Integer amount;
    private Complaint complaint;

    /**
     * @return the jobDone_id
     */
    @GenericGenerator(name = "generator", strategy = "foreign", parameters = @Parameter(name = "property", value = "Complaint"))
    @Id
    @GeneratedValue(generator = "generator")
    @Column(name = "jobDone_id", unique = true, nullable = false)
    public Integer getJobDone_id() {
        return jobDone_id;
    }

    /**
     * @param jobDone_id the jobDone_id to set
     */
    public void setJobDone_id(Integer jobDone_id) {
        this.jobDone_id = jobDone_id;
    }

    /**
     * @return the nature
     */
    public String getNature() {
        return nature;
    }

    /**
     * @param nature the nature to set
     */
    public void setNature(String nature) {
        this.nature = nature;
    }

    /**
     * @return the amount
     */
    public Integer getAmount() {
        return amount;
    }

    /**
     * @param amount the amount to set
     */
    public void setAmount(Integer amount) {
        this.amount = amount;
    }

    /**
     * @return the complaint
     */
    @OneToOne(fetch = FetchType.LAZY)
    @PrimaryKeyJoinColumn
    public Complaint getComplaint() {
        return complaint;
    }

    /**
     * @param complaint the complaint to set
     */
    public void setComplaint(Complaint complaint) {
        this.complaint = complaint;
    }
}

SQL查询：

CREATE DATABASE jobcard;
USE jobcard;
CREATE TABLE Complaint(
    jobNumber varchar(100),
    complaint_id int(10) primary key NOT NULL AUTO_INCREMENT,
    nature varchar(200),
    instruction varchar(200),
    constraint foreign key(jobNumber) references JobCard(jobNumber) 
    on delete cascade on update cascade  
);

CREATE TABLE JobDone(
    complaint_id int(10),
    jobDone_id int(10) primary key NOT NULL AUTO_INCREMENT,
    nature varchar(200),
    amount int,
    constraint foreign key(complaint_id) references Complaint(complaint_id) 
    on delete cascade on update cascade     
);

我创建了hibernate.cfg.xml文件，并映射了两个类的完全限定类名。为什么我会犯这个错误

更新

这是工作

投诉类别：

@OneToOne(fetch = FetchType.LAZY)
@PrimaryKeyJoinColumn
public JobDone getJobDone() {
    return jobDone;
}

作业完成类：

@OneToOne(fetch = FetchType.LAZY, mappedBy = "jobDone", cascade = CascadeType.ALL)
public Complaint getComplaint() {
    return complaint;
}

---

显然，问题在于

jobDone

中没有属性

jobDone

。您可以使用此映射

public class Compilant {

    @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    public JobDone getJobDone() {
        return jobDone;
    }

}

您将在

投诉

至

作业完成

中有一个外键。您可以从

JobDone

中删除

compileant

属性

如果您想在

作业完成

中也与

投诉

关联（这不是很方便）

如果只想在

JobDone

public class Compilant {

    @OneToOne(fetch = FetchType.LAZY, mappedBy = "complaint" cascade = CascadeType.ALL)
    public JobDone getJobDone() {
        return jobDone;
    }

}

public class JobDone {

   @OneToOne(fetch = FetchType.LAZY)
   public Complaint getComplaint() {
        return complaint;
    }

}

---

这是因为您在一个位置（小j）使用了jobDone，而在另一个位置（大写j）使用了jobDone。纠正这一点，问题就应该解决。

尝试发布配置xml文件这是一个非常奇怪的假设：）@asankajaasinghe更改为什么？

public class JobDone {

   @OneToOne(fetch = FetchType.LAZY)
   public Complaint getComplaint() {
        return complaint;
    }

}     

public class Compilant {

    @OneToOne(fetch = FetchType.LAZY, mappedBy = "complaint" cascade = CascadeType.ALL)
    public JobDone getJobDone() {
        return jobDone;
    }

}

public class JobDone {

   @OneToOne(fetch = FetchType.LAZY)
   public Complaint getComplaint() {
        return complaint;
    }

}
