如何在Grails GORM中强制刷新 [英] How to force flushing in Grails GORM

问题描述

我有一项向操作员分配任务的服务。
在一个方法中，我在循环内及时分配许多任务。我想冲洗任务，操作员和DistributionLog。如果我只有一个域来保存，我想我可以做一些像

  Operator.withTransaction {//...some code } 
  

但我至少有3个域名要保存，并且更糟糕，其中两个域名相互依赖。操作员有一个任务列表。

在操作员可以完成任务之前，我无法等待所有分配完成，因此我必须强制它完成冲洗。为了使它更难，它全部放在multitenantService.doWithTenant（）（多租户插件）中。

您可以使用会话来获取会话所有域类中都有 withSession 方法，并调用 flush（）。

  Operator.withSession {session  - > 
 // ... 
 session.flush（）
} 
  

I have a service that distributes tasks to operators. Inside a method I distribute many tasks in time inside a loop. I want to flush the task, the operator, and a DistributionLog. If I just had one domain to save I think I could do something like

Operator.withTransaction{ //...some code }

but I have at least 3 domains to save and to make it even worse, two of them have dependency on each other. The operator have a list of tasks.

I can't wait all the distribution to finish before an operator can get his tasks, so I have to force it to flush. To make it even harder, it's all inside a multitenantService.doWithTenant() (multitenant plugin)

解决方案

You can get the session using the withSession method available in all domain classes and call to flush() on it.

Operator.withSession { session ->
   // ...
   session.flush()
}
