是否有可能使@Formula注释延迟加载的？ [英] Is it possible to make @Formula annotation lazily loaded?

问题描述

我用 @Formula 注释用它获取计算性能。我需要的是，这些领域/干将被注解为 @Formula 标注应延迟加载。

I have used @Formula annotation to use it for getting calculated properties. What I need is that those fields/getters which is annotated with @Formula annotation should be lazily loaded.

这甚至可能如果又如何？

Is this even possible and if so how?

感谢

推荐答案

是的。只是注释字段通过的 @Formula 属性的getter Basic.html＃获取％28％29相对=nofollow> @基本（取= FetchType.LAZY），并使用该<一个href=\"http://docs.jboss.org/hibernate/orm/3.6/javadocs/org/hibernate/tool/instrument/javassist/InstrumentTask.html\"相对=nofollow> Ant任务由Hibernate提供以做实体类的字节code仪器。否则，对于 @Formula 属性延迟加载忽略。

Yes . Just annotating the fields/getter of the @Formula property by @Basic(fetch=FetchType.LAZY) and use this ant task provided by hibernate to do the bytecode instrumentation for the entity class. Otherwise , LAZY loading for the @Formula property is silently ignored.

的<一个href=\"http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/performance.html#performance-fetching-lazyproperties\"相对=nofollow>文档包含如何使用此ant任务做字节code仪表的信息。

The documentation contains the info on how to use this ant task to do bytecode instrumentation.
