我在将 java ee 应用程序部署到 weblogic 服务器 12.x 时遇到此错误:

我的佣金类代码是:

@Entity

这是 SalesRepCommission 类代码:

package net.tbse.back.inventory.salesRep.entities;

  private Double toAmount;



    public void setSalesRepCommissionsId(Long salesRepCommissionsId) {
        this.salesRepCommissionsId = salesRepCommissionsId;
    }

  @TableGenerator(name = "SalesRepCommisionsGenerator", table = "SEQUENCE",
                  pkColumnName = "SEQ_NAME", valueColumnName = "SEQ_COUNT",
                  pkColumnValue = "SALES_REP_COMMISSIONS")
  @GeneratedValue(strategy = GenerationType.TABLE, generator = "SalesRepCommisionsGenerator")
  @Id
  @Column(name = "SALES_REP_COMMISSIONS_ID", nullable = false)
    public Long getSalesRepCommissionsId() {
        return salesRepCommissionsId;
    }


    public void setSaleRep(SalesRep saleRep) {
        this.saleRep = saleRep;
    }

  @ManyToOne
  @JoinColumn(name = "SALES_REP_ID")
    public SalesRep getSaleRep() {
        return saleRep;
    }


    public void setCommission(Commission commission) {
        this.commission = commission;
    }

    @OneToOne
  @JoinColumn(name = "COMMISSION_ID")
    public Commission getCommission() {
        return commission;
    }

    public void setSalesPeriodCommissions(Map<Long, Target> salesPeriodCommissions) {
        this.salesPeriodCommissions = salesPeriodCommissions;
    }

@Transient
    public Map<Long, Target> getSalesPeriodCommissions() {
        return salesPeriodCommissions;
    }

    public void setToAmount(Double toAmount) {
        this.toAmount = toAmount;
    }

@Column(name = "TO_AMOUNT")
    public Double getToAmount() {
        return toAmount;
    }

    public void setFromAmount(Double fromAmount) {
        this.fromAmount = fromAmount;
    }
  @Column(name = "FROM_AMOUNT")
    public Double getFromAmount() {
        return fromAmount;
    }
}

这是 persistance.xml 文件:

persistance.xml

此外，我还检查了 persistence.xml 并且该类已正确包含在同一包中。编译过程成功完成并生成了一个jar文件。

有人可以帮我解决这个问题吗？这里肯定有错误，但我找不到它。

Answer 1

我认为类Commission未声明为@Entity。显示其代码。
