@NotFound解决关联外键数据不存在时抛出异常的问题

使用hibernate 注解配置实体类的关联关系，在many-to-one,one-to-one关联中，一边引用自另一边的属性，如果属性值为某某的数据在数据库不存在了，hibernate默认会抛出异常。解决此问题，加上如下注解就可以了：
@NotFound(action=NotFoundAction.IGNORE)，意思是找不到引用的外键数据时忽略，NotFound默认是exception



下面贴出hibernate 注解的实例代码



@Entity
@Table(name = "ICT_COMPUTER_LOCATION")
public class IctComputerLocation {
private static final long serialVersionUID = 1L;

private Integer id;
/** IDC编号 */
private String idcNum;

private Integer ictBaseId;

/** IctBase实体类 */
private IctBase ictBase;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "ID")
public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}

@Column(name = "IDC_NUM")
public String getIdcNum() {
return idcNum;
}

public void setIdcNum(String idcNum) {
this.idcNum = idcNum;
}

@Column(name = "ICT_BASE_ID")
public Integer getIctBaseId() {
return ictBaseId;
}

public void setIctBaseId(Integer ictBaseId) {
this.ictBaseId = ictBaseId;
}

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "ICT_BASE_ID", referencedColumnName = "ID", unique = false, nullable = false, insertable = false, updatable = false)
@NotFound(action=NotFoundAction.IGNORE)
public IctBase getIctBase() {
return ictBase;
}

public void setIctBase(IctBase ictBase) {
this.ictBase = ictBase;
}
