java EclipseLink分布式缓存导致主键为空，是什么？

3 月，3 周 Questions & Answers

好的，这会很长，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开始缓慢下降，并抛出一个非常奇怪的异常。“修复”是禁用缓存。真糟糕。请帮助我们在EclipseLink中找到问题，以便我们可以修补它

日食2.5.1

我们有以下实体：

@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对客户进行写入/更新，App2对Notes进行写入/更新。它们都使用完全相同的持久化单元库jar。运行一段时间后，notes应用程序最终开始失败，并对特定客户对象执行此堆栈跟踪。重新启动服务器可修复此问题，直到另一个客户对象开始出现此问题

    默认情况下，Eclipselink不进行分布式更新。改为尝试@Cache（coordinationType=CacheCoordinationType.INVALIDATE\u CHANGED\u对象）

  2. # 2 楼答案

    一定是一只虫子埋在日食的深处。。。禁用另一个优化修复了该问题：

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

    糟糕透了
