我已将我的 Hibernate 缓存从 EHCache 切换到 Infinispan，现在我在修改具有复合主键的实体时遇到异常。实体如下:
@Entity
@Table(name="Company_Message_Type")
@Cache(usage=CacheConcurrencyStrategy.TRANSACTIONAL)
public class CompanyMessageType implements Serializable
{
private static final long serialVersionUID = 1L;
@EmbeddedId private final CompanyMessageTypeId id = new CompanyMessageTypeId();
@Column(name="FL_EXTERNAL_ACCESS", nullable=false)
private boolean externalAccess;
@Column(name="FL_VIEW_CONTENT", nullable=false)
private boolean viewContent;
@MapsId("companyId")
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ID_COMPANY", nullable=false)
private Company company;
@MapsId("messageTypeId")
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ID_MESSAGE_TYPE", nullable=false)
private MessageType messageType;
}
嵌入的Id类如下:
@Embeddable
public class CompanyMessageTypeId implements Serializable
{
private static final long serialVersionUID = 1L;
@Column(name="ID_COMPANY", nullable=false)
private Long companyId;
@Column(name="ID_MESSAGE_TYPE", nullable=false)
private Long messageTypeId;
}
这两个类都有合理的 equals() 和 hashCode() 方法。
只有当集群中有多台服务器时才会出现异常。异常出现在正在更新的服务器上。堆栈跟踪如下:

有没有人见过这个错误？似乎 infinispan 可能没有正确序列化嵌入的 id 类。
我正在使用 Hibernate 4.3.5 和 Infinispan 6.0.2
编辑:
问题在于 Infinispan 正在通过网络发送 CacheKey 的序列化版本。此 key 间接引用发起机器上的 SessionFactoryImpl，但远程机器无法反序列化 SessionFactoryImpl，因此抛出此异常。我相信这个问题特定于具有复合主键的实体，因为如果键只是一个 Long，则 CacheKey 的 type 将是某种东西else 不间接引用 SessionFactoryImpl。
综上所述，我不确定这是 Infinispan 问题还是 Hibernate 问题。
最佳答案
正如在 pull request 上讨论的那样，显然 SessionFactory 只要被命名就可以跨 JVM 序列化(参见 HHH-6822 )。为了解决我的问题，我只需要在 session 工厂上设置以下 Hibernate 属性:
hibernate.session_factory_name = MySessionFactory
hibernate.session_factory_name_is_jndi = false
