HIbernate映射exception：PropertyNotFoundException：找不到setter
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exception“你应该有setter属性”
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 stockDetails = new HashSet(0); public Set getStockDetails() { return stockDetails; } public void setStockDetails(Set 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"; } } 库存详情类
@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(); }

请问任何人请让我知道，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
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。
Ps从Hibernate 3开始，默认情况下是懒惰的，所以不需要将它显式标记为懒惰。
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的名称不正确; 它与它设置的属性不匹配。 就这样
