Re: [T5.06snap] About PERTHREAD_SCOPE?

I use IE and Firefox to request the index page, the index page read data
from the BoboCachestate, and got defferent data!
They should be same!

Re: [T5.06snap] About PERTHREAD_SCOPE?

[Howard Lewis Ship]

What makes you think that it builds a singleton?

You will get a single proxy instance; internal to the proxy it finds/creates
the per-thread instance.

You need to be careful about the notification you have there; that will
probably cause a leak of BoboCacheState instances.

@Scope(PERTHREAD_SCOPE)
public BoboCacheState buildCacheState(ThreadCleanupHub threadCleanupHub,
@InjectService

   threadCleanupHub.addThreadCleanupListener(new
ThreadCleanupListener() {
public void threadDidCleanup() {
  cache.getCacheEventNotificationService
().unregisterListener(state);
   });



return state;

[T5.06snap] About PERTHREAD_SCOPE?

[Donyee]

I use "@Scope(PERTHREAD_SCOPE)" on build method  in my AppModule.java.
It will create new instance in every new request, but it seems the method
build a singleton!
I use IE and FireFox request the page!
my code: in AppModule.java
@EagerLoad
@Scope(PERTHREAD_SCOPE)
public BoboCacheState buildCacheState(@InjectService("Cache")
Cache cache) {
BoboCacheState state = new BoboCacheState();
cache.getCacheEventNotificationService().registerListener(state);
return state;
}
in page index.java:
@Inject
private BoboCacheState state;
