EntityListener 的@PreUpdate 中的 EJB 上下文 JNDI 查找失败

Question

我有一个 JPA EntityListener，我在其中为 "java:comp/EJBContext" 在 @PrePersist 和 @PreUpdate 回调中执行相同的 JNDI 查找方法。虽然在 @PrePersist 回调方法期间查找成功，但在 @PreUpdate 回调方法期间一直失败。

我正在使用 Hibernate 4.2。19.Final 和 Websphere AS 8.5.5.3 build cf031430.01 (Java EE 6 / EJB 3.1 / JPA 2.0)。

代码很简单：

public class AuditedEntityListener {

  private static final Logger LOGGER = LoggerFactory.getLogger(AuditedEntityListener.class);

  private static final String STANDARD_EJB_CONTEXT_NAME = "java:comp/EJBContext";

  SessionContext lookupSessionContext() {
    try {
      return InitialContext.doLookup(STANDARD_EJB_CONTEXT_NAME);
    } catch (NamingException ne) {
      LOGGER.error("Lookup failure", ne);
      return null;
    }
  }

  @PrePersist
  void prePersist(IAuditedEntity entity) {
    lookupSessionContext();
  }

  @PreUpdate
  void preUpdate(IAuditedEntity entity) {
    lookupSessionContext();
  }

}

这是痕迹：

正如 Brett 指出的那样，这是 IBM 方面的错误。该问题已在 Websphere 8.5.5.9 版中修复。
