Question

我有两个POJO，STOCK和STOCK_DETAILS（一对多的关系）。我还有一个接口IAUDITLOG（有两种方法）。我需要用BOTH POJO实现这个接口，并希望在这些方法中编写一些实现。但是当我用子类“STOCKDETAILS”实现IAUDITLOG接口时，它会给出异常“你应该有setter属性”

股票类：

@Entity
@Table(name = "stock")
public class Stock implements java.io.Serializable, IAuditLog
{   
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "id")
    private Integer stockId;

    @Column(name = "STOCK_CODE")
    private String stockCode;

    @Column(name = "STOCK_NAME")
    private String stockName;

    @OneToMany( fetch = FetchType.LAZY, mappedBy = "stock")
    public Set<StockDetail> stockDetails = new HashSet<StockDetail>(0);


    public Set<StockDetail> getStockDetails() {
        return stockDetails;
    }

    public void setStockDetails(Set<StockDetail> stockDetails) {
        this.stockDetails = stockDetails;
    }

    public Integer getStockId() {
        return stockId;
    }

    public void setStockId(Integer stockId) {
        this.stockId = stockId;
    }

    public String getStockCode() {
        return stockCode;
    }

    public void setStockCode(String stockCode) {
        this.stockCode = stockCode;
    }

    public String getStockName() {
        return stockName;
    }

    public void setStockName(String stockName) {
        this.stockName = stockName;
    }

// overridded methods of IAUDITLOG interface
    public int getLogId() {

        return stockId;
    }
    public String getLogDetail() {      
        return "some implementaion";
    }
}

股票详情类

@Entity
@Table(name = "StockDetail")
public class StockDetail implements Serializable, IAuditLog {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private Integer recordId;
    private Stock stock;
    private Float priceOpen;


    @Id
    @GeneratedValue
    @Column(name = "RECORD_ID", unique = true, nullable = false)
    public Integer getRecordId() {
        return this.recordId;
    }

    public void setRecordId(Integer recordId) {
        this.recordId = recordId;
    }

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "STOCK_ID", nullable = false)
    public Stock getStock() {
        return this.stock;
    }

    public void setStock(Stock stock) {
        this.stock = stock;
    }

    @Column(name = "PRICE_OPEN", precision = 6)
    public Float getPriceOpen() {
        return this.priceOpen;
    }

    public void setPriceOpen(Float priceOpen) {
        this.priceOpen = priceOpen;
    }

    //overriddded methods of IADUTILOG inteface
    public int getLogId() {
        // TODO Auto-generated method stub
        return 0;
    }

    public String getLogDetail() {
        // TODO Auto-generated method stub
        return "some implementation";
    }
}

IAUDITLOg界面：

public interface IAuditLog {
    public int getLogId();
    public String getLogDetail();
}

任何人都可以让我知道，可能是什么问题？为什么我应该为那些非ACTUALLY属于该类的属性创建getter和setter，而是从其他一些接口实现。仅供参考...当我使用Parent类“STOCK”

实现此接口时，这很好用

Answer 1

您应该使用@Transient注释重写的方法。

http://docs.oracle.com/javaee/5/api/javax/persistence/Transient.html

此批注指定属性或字段不是持久的。它用于注释实体类，映射的超类或可嵌入类的属性或字段。

P.S。从Hibernate开始，默认情况下3个集合是惰性的，因此不需要将其明确标记为惰性。

Answer 2

对于其他遇到此问题并且上述解决方案无效的人，我的错误是我的setter名称不正确;它与它设置的属性不匹配。这就是全部

HIbernate映射异常：PropertyNotFoundException：找不到setter
