Grails会话范围的服务 - 不起作用 [英] Grails session-scoped service - not working

问题描述

我在其中一个Grails服务（Grails 2.2.2）中添加了 static scope =session，但由于某种原因，它的行为类似于单例。

你能否将会话服务注入到单例（默认）服务中？

换句话说，有什么理由不应该这样做？

  class DefaultService {
 def sessionService 
} 
 
 class SessionService {
 static scope ='session'
 
 def instanceVar = ... 
} 
  

我该如何解决为什么这不起作用？

解决方案

我希望这个帮助你。

简而言之，你不能在单身人士中使用会话范围的服务，标签库。手动使用服务代理，或作用域代理插件。

I added static scope = "session" in one of my Grails services (Grails 2.2.2), but for some reason it is behaving like a singleton.

Can you not inject session services into singleton (default) services?

In other words, is there any reason why this shouldn't work?

class DefaultService {
  def sessionService
}

class SessionService {
  static scope = 'session'

  def instanceVar = ...
}

How would I troubleshoot why this isn't working?

解决方案

I hope this help you.

In short, you can not use session scoped services in singletons, like usual services or taglibs. Use service proxy by manually, or Scoped Proxy Plugin.
