为什么在应用程序启动时会记录空的 org.eclipse.persistence 消息？

Question

使用

• EclipseLink 2.4.1
• JBoss AS 7.1.1

问题

我开发了一个使用 EclipseLink 实现持久性的 servlet。

当应用程序启动时，我在服务器日志中多次重复收到以下消息：

12:17:45,586 WARN  [org.eclipse.persistence.metadata] (MSC service thread 1-1) Reverting the lazy setting on the OneToOne or ManyToOne attribute [CategoryCode] for the entity class [class se.magos.domain.Site] since weaving was not enabled or did not occur.
12:17:45,825 INFO  [org.eclipse.persistence.connection] (MSC service thread 1-1) vfs:/C:/Dev/Applications/JBoss/jboss-as-7.1.1.Final/standalone/deployments/Ear.ear/Persistence-1.0-SNAPSHOT.jar/_foo login successful

12:17:45,898 WARN  [org.eclipse.persistence] (MSC service thread 1-1) 
12:17:45,900 WARN  [org.eclipse.persistence] (MSC service thread 1-1) 
...and it goes on and on...
12:17:46,091 WARN  [org.eclipse.persistence] (MSC service thread 1-1) 
12:17:46,093 WARN  [org.eclipse.persistence] (MSC service thread 1-1) 
12:17:46,097 WARN  [org.eclipse.persistence] (MSC service thread 1-1) 
12:17:46,236 INFO  [org.jboss.as] (MSC service thread 1-3) JBAS015951: Admin console listening on http://127.0.0.1:9990

它接近域和服务对象的计数并且组合但不准确。

此日志消息的原因可能是什么？如何消除它？

Answer 1

JBoss AS 7 不使用 EclipseLink，因为它是 JPA 实现。它默认使用休眠。然而，有一个 article 解释了如何将 EclipseLink 与 JBoss AS 7 一起使用。

不过，我鼓励您使用 JPA，因为它比使用供应商特定的 JPA 实现更便携。
