Hibernate自引用查詢時實體重複字段

我有這個實體。Hibernate自引用查詢時實體重複字段

@Entity 
@Table(name = "CarePlan") 
public class CarePlan extends Updateable{ 

    @Column(name = "careplan_system") 
    private String system; 

    @Column(name = "careplan_code",unique = true) 
    private String code; 

    @Column(name ="description") 
    private String description; 

    @OneToMany(fetch = FetchType.EAGER,mappedBy = "carePlan") 
    private Set<CarePlan> subsections = new HashSet<>(); 

    @ManyToOne(cascade={CascadeType.ALL}) 
    @JoinColumn(name="carePlan_code") 
    private CarePlan carePlan; 

    public String getSystem() { 
     return system; 
    } 

    public void setSystem(String system) { 
     this.system = system; 
    } 

    public String getCode() { 
     return code; 
    } 

    public void setCode(String code) { 
     this.code = code; 
    } 

    public String getDescription() { 
     return description; 
    } 

    public void setDescription(String description) { 
     this.description = description; 
    } 

    public Set<CarePlan> getSubsections() { 
     return subsections; 
    } 

    public void setSubsections(Set<CarePlan> subsections) { 
     this.subsections = subsections; 
    } 

    public CarePlan getCarePlan() { 
     return carePlan; 
    } 

    public void setCarePlan(CarePlan carePlan) { 
     this.carePlan = carePlan; 
    } 
}

不過，我一直在收到此錯誤

這是我的SQL腳本，我用來生成表。

CREATE TABLE CarePlan (
    id bigserial NOT null PRIMARY KEY, 
    time_created timestamptz DEFAULT now() NOT NULL, 
    time_updated timestamptz DEFAULT now() NOT NULL, 
    careplan_system VARCHAR(50), 
    careplan_code VARCHAR(50) UNIQUE, 
    description VARCHAR(500), 
    parent_careplan_code VARCHAR(50), 
    FOREIGN KEY (parent_careplan_code) REFERENCES CarePlan (careplan_code) 
);

我錯過了什麼？

將你的實體重命名爲這樣的東西。在這個

@JoinColumn(name = "parent_careplan_code",referencedColumnName = "code")

parent_careplan_code

@Entity 
@Table(schema = "siva", name = "CarePlan") 
public class CarePlan extends Updateable { 

    @Column(name = "careplan_system") 
    private String system; 

    @Column(name = "code") 
    private String code; 

    @Column(name = "description") 
    private String description; 

    @ManyToOne(cascade = {CascadeType.ALL}) 
    @JoinColumn(name = "parent_careplan_code",referencedColumnName = "code") 
    private CarePlan manager; 

    @OneToMany(mappedBy = "manager",fetch = FetchType.EAGER) 
    private Set<CarePlan> subsections = new HashSet<>(); 


    public String getSystem() { 
     return system; 
    } 

    public void setSystem(String system) { 
     this.system = system; 
    } 

    public String getCode() { 
     return code; 
    } 

    public void setCode(String code) { 
     this.code = code; 
    } 

    public String getDescription() { 
     return description; 
    } 

    public void setDescription(String description) { 
     this.description = description; 
    } 

    public Set<CarePlan> getSubsections() { 
     return subsections; 
    } 

    public void setSubsections(Set<CarePlan> subsections) { 
     this.subsections = subsections; 
    } 

    public void setManager(CarePlan manager) { 
     this.manager = manager; 
    } 

    public CarePlan getManager() { 
     return manager; 
    } 
}

採取值得注意的是你的forei名
