HIbernate映射异常：PropertyNotFoundException：无法找到setter [英] HIbernate Mapping Exception: PropertyNotFoundException: Could not find a setter
本文介绍了HIbernate映射异常：PropertyNotFoundException：无法找到setter的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有两个POJO，STOCK和STOCK_DETAILS（一对多关系）。
我也有一个接口IAUDITLOG（有两种方法）。我需要用BOTH POJO来实现这个接口，并且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，它会给出例外情况你应该拥有setter属性
STOCK CLASS：
@Entity
@Table（name =stock）
public class Stock实现java.io.Serializable，IAuditLog
{
@Id
@GeneratedValue（strategy = GenerationType.IDENTITY）
@Basic（可选= 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;
}
// IAUDITLOG接口的重写方法
public int getLogId（）{
return stockId;
}
public String getLogDetail（）{
returnsome implementaion;
$ / code $ / pre

@Entity

public class StockDetail实现Serializable，IAuditLog {

}
public void setRecordId（Integer recordId）{
this.recordId = recordId;
@ManyToOne（fetch = FetchType.LAZY）

}
public void setStock（股票股票）{

@Column（name =PRICE_OPEN，precision = 6）
public Float getPriceOpen（）{
return this.priceOpen;
}
public void setPriceOpen（Float priceOpen）{
this.priceOpen = priceOpen;
}
// IADUTILOG接口的重写方法
public int getLogId（）{
// TODO自动生成的方法存根
return 0;
}
public String getLogDetail（）{
// TODO自动生成的方法存根
返回某些实现;
}
}
IAUDITLOg界面：
public interface IAuditLog {
public int getLogId（）;
public String getLogDetail（）;
}

可以任何人请让我知道，可能是什么问题？为什么我应该为那些不属于该类的属性创建getter和setter，而是从其他接口实现。
FYI ...当我使用Parent类STOCK实现这个接口时，这工作正常
解决方案您应该注释使用@Transient重写的方法。
http://docs.oracle.com/javaee/5/api/javax/persistence/Transient.html
这个注解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。因为Hibernate 3默认情况下是懒惰的，所以不需要明确标记为懒惰。
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"
STOCK CLASS:
@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() {

}
}

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"
解决方案 You should annotate the overridden methods with @Transient.
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.
P.s. As of Hibernate 3 collections are lazy by default so there is no need to explicitly mark it as lazy.
这篇关于HIbernate映射异常：PropertyNotFoundException：无法找到setter的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
