java - org.hibernate.DuplicateMappingException:表包含由多个物理列名称引用的物理列名称[coverage_name]:

我正在使用下面的类，但是给出了类似的异常，原因如下:org.hibernate.DuplicateMappingException:表[]包含由多个物理列名称引用的物理列名称[scheme_name]:[SCHEME]，[schemeName]帮助我解决此问题。

@Embeddable
public class DRollSchemesId implements Serializable{

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "ROLL_NO", length = 20)
    private String rollNo;

    @Id
    @Column(name = "SCHEME", length = 100, updatable = false, insertable = false )
    private String schemeName;

   public DRollSchemesId() {
   }

   public DRollSchemesId(String rollNo, String schemeName) {
      this.rollNo = rollNo;
      this.schemeName = schemeName;
   }

   public String getrollNo() {
       return this.rollNo;
   }

   public void setrollNo(String rollNo) {
       this.rollNo = rollNo;
   }
   public String getschemeName() {
       return this.schemeName;
   }

   public void setschemeName(String schemeName) {
       this.schemeName = schemeName;
   }

这是实体，我正在尝试通过使用那个Embeddable类使用复合键。

@Entity
@Table(name = "D_ROLL_SCHEMES")
  @IdClass(DRollSchemesId.class)
public class DRenewalAddonCoverages  implements java.io.Serializable{

  private static final long serialVersionUID = 1L;

  private DRollSchemesId id;
  @Id
  @Column(name = "ROLL_NO", length = 20)
    private String rollNo;

  @Id
  @Column(name = "SCHEME", length = 100, updatable = true, insertable
= true )
    private String schemeName;



    public DRenewalAddonCoverages(){
    }


  @Id
  @AttributeOverrides(
      {
        @AttributeOverride(column = @Column(name = "ROLL_NO",
updatable = true, insertable = true), name = "rollNo"),
        @AttributeOverride(column = @Column(name = "SCHEME", updatable
= true, insertable = true), name = "schemeName")

      })

  @EmbeddedId
  public DRollSchemesId getId() {
        return this.id;
    }


    public String getrollNo() {
    return rollNo;
  }


  public void setrollNo(String rollNo) {
    this.rollNo = rollNo;
  }


  public String getschemeName() {
    return schemeName;
  }

  public void setschemeName(String schemeName) {
    this.schemeName = schemeName;
  }


  public void setId(DRollSchemesId id) {
        this.id = id;
    }

}

最佳答案

尝试如下:

class DRollSchemesId implements Serializable {
    private String rollNo;
    private String schemeName;
}

@Entity
@Table(name = "D_ROLL_SCHEMES")
@IdClass(DRollSchemesId.class)
public class DRenewalAddonCoverages implements java.io.Serializable {

    @Id
    @Column(name = "ROLL_NO", length = 20)
    private String rollNo;

    @Id
    @Column(name = "SCHEME", length = 100, updatable = true, insertable = true)
    private String schemeName;

}
