具有复合主键的Hibernate实体的Infinispan编组错误

我已将Hibernate缓存从EHCache切换到Infinispan，我现在在使用复合主键修改实体时遇到异常。该实体如下：

@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;
}

嵌入式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。

仅当群集中有多个服务器时才会发生异常。正在更新的服务器上出现异常。堆栈跟踪如下：

之前有没有人见过这个错误？看起来infinispan可能无法正确地序列化嵌入式id类。

我使用的是Hibernate 4.3.5和Infinispan 6.0.2

修改

问题在于Infinispan正在通过网络发送CacheKey的序列化版本。此密钥间接引用启动计算机上的SessionFactoryImpl，但远程计算机无法反序列化SessionFactoryImpl，因此会抛出此异常。我认为该问题特定于具有复合主要内容的实体，因为如果密钥只是Long，则type的{​​{1}}将是其他不会间接引用的内容CacheKey。

总之，我不确定它是否是Infinispan问题或Hibernate问题。

1 个答案:

答案 0 :(得分：2)

正如pull request所讨论的，显然SessionFactory可以在JVM上进行序列化，只要它被命名（参见HHH-6822）。为了解决我的问题，我只需要在会话工厂上设置以下Hibernate属性：

hibernate.session_factory_name = MySessionFactory
hibernate.session_factory_name_is_jndi = false
