我有这个实体。

@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;
    }
}

但是，我一直收到此错误

这是我用来生成表格的SQL脚本。

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)
);

我错过了什么？

将您的实体重命名为此类。

@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;
    }
}

注意这个

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

parent_careplan_code是你的外国人的名字

我发现此问题与spring-boot/2129和HIBERNATE-160有关，该问题的解决方法是添加以下内容：

spring.jpa.hibernate.naming:
  implicit-strategy: "org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl"
  physical-strategy: "org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl"

或使用等效的属性文件。
