Hibernate异常：No row with the given identifier exists

Hibernate中常见问题 No row with the given identifier exists问题的原因及解决上面引用的这篇文章，解释的挺好的，可以参考。还有一种关于这个Hibernate异常的解决方法：就是在Hibernate框架下，各个类都存在着互相引用的关系，websiteInfo 网站表 和 UserInfo 用户表，w 表 依赖 u表。比如：张三 创建了 一个网站数据。website实体：

@Entity
@Table(name = "TBL_WEBSITE_INFO", schema = "SSP")
public class WebsiteInfo implements java.io.Serializable {

// Fields

private static final long serialVersionUID = -5020142908658683873L;
private long id;
private String websiteName;
private String websiteUrl;
private UserInfo userId;

// Constructors

/**
* default constructor
*/
public WebsiteInfo() {
}
.

.
getter （） 和 setter () ....<pre name="code" class="java">.<span style="white-space:pre">	</span>

<span style="white-space:pre">	</span>@Id
<span>	</span>@SequenceGenerator(name = "seqWEBSITE", sequenceName = "SSP_WEBSITE")
<span>	</span>@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seqWEBSITE")
<span>	</span>@Column(name = "ID", unique = true, nullable = false, precision = 10, scale = 0)
<span>	</span>public long getId() {
<span>		</span>return this.id;
<span>	</span>}

<span>	</span>public void setId(long id) {
<span>		</span>this.id = id;
<span>	</span>}

<span style="white-space:pre">	</span>@ManyToOne(cascade = { CascadeType.MERGE, CascadeType.REFRESH }, optional = true)<span style="white-space:pre">	</span>@JoinColumn(name = "USER_ID")<span style="white-space:pre">	</span>public UserInfo getUserId() {<span style="white-space:pre">		</span>return this.userId;<span style="white-space:pre">	</span>}<span style="white-space:pre">	</span>public void setUserId(UserInfo userId) {<span style="white-space:pre">		</span>this.userId = userId;<span style="white-space:pre">	</span>}

<span style="white-space:pre">	</span>。。。。

比如 jack 创建了一条website的数据，当你在查询网站数据的时候，hibernate就会根据映射关系，也会加载userinfo的表，去找 jack 这条数据，如果找不到，那么就会抛异常org.springframework.orm.hibernate4.HibernateObjectRetrievalFailureException: No row with the given identifier exists:对应这个异常，可以这样的处理逻辑，比如 jack 创建了一条 website 数据，但是，jack 数据在 userinfo表中被删除了，当websiteinfo 表 映射到 userinfo表查找 jack这条数据时，如果找不到，就忽略。添加一个Hibernate 的注解

@ManyToOne(cascade = { CascadeType.MERGE, CascadeType.REFRESH }, optional = true)<span style="color:#ff0000;">@NotFound(action=NotFoundAction.IGNORE)</span>@JoinColumn(name = "USER_ID")public UserInfo getUserId() {return this.userId;}public void setUserId(UserInfo userId) {this.userId = userId;}
