HIbernate Mapping Exception: PropertyNotFoundException: Could not find a setter
提问by user3029929
I have two POJO's ,STOCK and STOCK_DETAILS (one to many relationship). Also I have one interface IAUDITLOG (having two methods). I need to implement this interface with BOTH POJO's and want to write some implementation within those methods. But when I implement IAUDITLOG interface with child class "STOCKDETAILS" then it gives exception "that you should have setter property"
我有两个 POJO 的 ,STOCK 和 STOCK_DETAILS（一对多关系）。我也有一个接口 IAUDITLOG（有两种方法）。我需要使用 BOTH POJO 来实现这个接口，并希望在这些方法中编写一些实现。但是当我使用子类“STOCKDETAILS”实现 IAUDITLOG 接口时，它会给出异常“你应该拥有 setter 属性”
STOCK CLASS:
股票类别：
@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";
}
}
STOCK DETAILS CLASS

CAN ANYONE PLEASE LET ME KNOW,what could be the problem??? Why should I create getter and setter for those properties which is not ACTUALLY belongs to that class, but implemented from some other interface. FYI... this works fine when I implement this interface with Parent class "STOCK"
任何人都可以让我知道，可能是什么问题？？？为什么要为那些实际上不属于该类，而是从其他接口实现的属性创建 getter 和 setter。仅供参考......当我用父类“STOCK”实现这个接口时，这很好用

You should annotate the overridden methods with @Transient.
您应该使用@Transient 注释覆盖的方法。
http://docs.oracle.com/javaee/5/api/javax/persistence/Transient.html
http://docs.oracle.com/javaee/5/api/javax/persistence/Transient.html
This annotation specifies that the property or field is not persistent. It is used to annotate a property or field of an entity class, mapped superclass, or embeddable class.
此注释指定属性或字段不是持久的。它用于注释实体类、映射超类或可嵌入类的属性或字段。
P.s. As of Hibernate 3 collections are lazy by default so there is no need to explicitly mark it as lazy.
Ps 从 Hibernate 3 开始，默认情况下集合是惰性的，因此无需显式地将其标记为惰性。

For others who come across this and the above solution does not work, my error was that the name for my setter was not correct; it did not match the property it was setting. That's all
对于遇到此问题并且上述解决方案不起作用的其他人，我的错误是我的 setter 的名称不正确；它与它正在设置的属性不匹配。就这样
