问题描述
我使用了 @Formula 注释来获取计算属性.我需要的是那些用 @Formula 注释注释的字段/getter 应该被延迟加载.
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.
这甚至可能吗?如果可能，怎么办?
Is this even possible and if so how?
谢谢
推荐答案
是.只需通过 并使用这个 ant task 由 hibernate 提供，用于对实体类进行字节码检测.否则，@Formula 属性的延迟加载将被静默忽略.
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.
文档 包含有关如何使用此 ant 任务进行字节码检测的信息.
The documentation contains the info on how to use this ant task to do bytecode instrumentation.
