EclipseLink分布式缓存导致空主键，什么？

好的，这将是很长的，所以这里是tl;dr：当启用分布式缓存协调时，其中一个应用程序的完整性会慢慢降低并引发一个非常奇怪的异常。修复＆＃39;是禁用缓存。哪个很烂。请帮助我们在EclipseLink中找到问题，以便我们对其进行修补！

EclipseLink 2.5.1

我们有这些实体：

@MappedSuperclass public abstract class Identifiable implements Serializable { private static final long serialVersionUID = 1L; @Id @Column(name = "id", nullable = false, updatable = false) @GeneratedValue(strategy = GenerationType.IDENTITY) public Integer id; @Version @Column(name = "meta__version") private Integer version; }

@Entity @Table(name = "customers", indexes = { @Index(columnList = "phone_number"), @Index(columnList = "email_address") }) @Cacheable public class Customer extends Identifiable { private static final long serialVersionUID = 1L; @Column(name = "last_name") public String lastName; @Column(name = "first_name") public String firstName; .... }

@Entity @Table(name = "notes", indexes = { @Index(columnList = "customer_id, is_cleared") }) @Cacheable public class Note extends Identifiable { private static final long serialVersionUID = 1L; @ManyToOne @JoinColumn(name = "customer_id") public Customer customer; @ManyToOne @JoinColumn(name = "agent_id") public Agent agent; @Size(min = 1, max = 32767) @Column(name = "text", length = 32767) public String text; @Column(name = "is_cleared") public Boolean isCleared; }

我们有两个应用程序。 App1在客户上编写/更新，App2在Notes上编写/更新。它们都使用完全相同的持久单元库jar。运行一段时间后，最终Notes应用程序开始因特定客户对象的堆栈跟踪而失败。重新启动服务器可以解决问题，直到另一个Customer对象开始发生。

2 个答案:

答案 0 :(得分：3)

Eclipselink默认执行分布式更新。尝试使用@Cache（coordinationType = CacheCoordinationType.INVALIDATE_CHANGED_OBJECTS）

答案 1 :(得分：1)

必须是深埋在EclipseLink内部的错误...禁用其他优化可以解决问题：

 <property
         name="eclipselink.weaving.internal"
         value="false" />

糟糕，
