Question

我在rcp应用程序中使用eclipselink，当第一次应用程序使用数据库时，我收到这些警告消息。此应用程序滞后1-2秒，直到jpa成功登录。如何停止此警告，此警告是否滞后于应用程序？

对于答案来说可能为时已晚，但它与ManyToOne或OneToOne关系以及LAZY加载有关。你可能会使用它，为此，eclipselink必须编织字节码（.class文件）。如果eclipselink无法编织代码（由于某些原因），那么它就不能使用LAZY加载....所以这可能是你的应用程序滞后的原因（如果不是LAZY则是EAGER加载，这可能需要一些额外的时间，直到从DB获取数据）。

Rcp with eclipselink支持动态编织
