问题是当@ManyToOne生成@联接列ID_REPORT（它是主键）和@联接列ID_TEMPLATE_DEFAULT时
实体Map中的列重复：当前报表列：id_report（应使用insert=“false”update=“false”进行Map）

代码
第一个表格CUR_TEMPLATE

CREATE TABLE CUR_TEMPLATE 
   (    
    ID_REPORT NUMBER(5,0) NOT NULL, 
    ID_TEMPLATE NUMBER(5,0) NOT NULL, 
    -- Other fields
   );
 
ALTER TABLE CUR_TEMPLATE ADD CONSTRAINT PK_CUR_TEMPLATE PRIMARY KEY (ID_REPORT, ID_TEMPLATE)

-- CUR_TEMPLATE foreign keys
ALTER TABLE CUR_TEMPLATE ADD CONSTRAINT FK_CUR_PLAN_REFERENCE_CUR_REPO FOREIGN KEY (ID_REPORT)
      REFERENCES CUR_REPORTS (ID_REPORT);

第二个数据表CUR_REPORTS

-- CUR_REPORTS definition
CREATE TABLE CUR_REPORTS 
   (    
    ID_REPORT NUMBER(3,0) NOT NULL, 
    NAME_REPORT VARCHAR2(100) NOT NULL, 
    -- other fields 
    ID_TEMPLATE_DEFAULT NUMBER(5,0), 
    -- other fields
   ) ;

ALTER TABLE CUR_REPORTS ADD CONSTRAINT PK_CUR_REPORTS PRIMARY KEY (ID_REPORT)

ALTER TABLE CUR_REPORTS CONSTRAINT FK_CUR_REPO_REFERENCE_CUR_PLAN FOREIGN KEY (ID_REPORT, ID_TEMPLATE_DEFAULT)
      REFERENCES CUR_TEMPLATE (ID_REPORT, ID_TEMPLATE)

第一个表格CUR_REPORTS实体CurReport

@Entity
@Table(name = "CUR_REPORTS")
@IdClass(CurPlantillaPK.class)
@Getter
@Setter
public class CurReport {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID_REPORT", nullable = false)
    private Long id;

    @Column(name = "NAME_REPORT", nullable = false, length = 100)
    private String nombreReporte;

    @ManyToOne(fetch = FetchType.LAZY) <---WHERE IS THE PROBLEM 
    @JoinColumn(name = "ID_REPORT", referencedColumnName = "ID_REPORTE")
    @JoinColumn(name = "ID_TEMPLATE_DEFAULT", referencedColumnName = "ID_TEMPLATE")
    private CurTemplate curTemplate;

    @OneToMany(mappedBy = "curReport")
    private Set<CurTemplate> curTemplates= new LinkedHashSet<>();
}

第二个表CUR_TEMPLATE实体当前报表

@Entity
@Table(name = "CUR_TEMPLATE")
@IdClass(CurPlantillaPK.class)
@Getter
@Setter
public class CurTemplate {
    
    @Id
    @Column(name = "ID_REPORT", nullable = false)
    private Long idReport;

    @Id
    @Column(name = "ID_TEMPLATE", nullable = false)
    private Long idTemplate;

    
    @ManyToOne(optional = false, fetch = FetchType.LAZY)
    @JoinColumn(name = "ID_REPORT", foreignKey = @ForeignKey(name = "FK_CUR_PLAN_REFERENCE_CUR_REPO"), referencedColumnName = "ID_REPORT", insertable = false, updatable = false)
    private CurReport curReport;

}

当i添加可插入=假，可更新=假时
@联接列（名称=“ID_REPORT”，引用列名=“ID_REPORT”，可插入=假，可更新=假）
所说的
不允许在属性中混合使用可插入列和不可插入列：当前模板
如何Map这些关系？当FK的一个字段是列PK时，如何解析@JoinColumn？
