Inject Issue in Cache modules and MVC

[Shbnv]

There is an issue with inject any Cache modules into MVC Controller. For example, Guava: { use(GuavaCache.newCache()); session(GuavaSessionStore.class); } @Inject public MyMVCRoutes( Cache cache) { this.cache = cache; } Getting error: `[2016-11-23 14:09:48,483]-[HotSwap] ERROR App - An error occurred while stating the application: com.google.inject.CreationException: Unable to create injector, see the following errors:

Hi @Shbnv

Try Cache<String, Object>, like:

@Inject public MyMVCRoutes( Cache<String, Object> cache) { this.cache = cache; }

[Shbnv]

I tried this already: 1) No implementation for com.google.common.cache.Cache<java.lang.String, java.lang.Object> was bound. while locating com.google.common.cache.Cache<java.lang.String, java.lang.Object>

Found it!

Did you create a guava.session entry in .conf file for GuavaSessionStore, right?

That overrides the default guava cache and results in the error you are seeing now. Try this:

guava.cache = "maximumSize=10"
guava.session = "maximumSize=10"

The guava.cache is the default cache (the one created by GuavaCache.newCache()).

Guess we can probably improve this... not sure.

Yes! Thank you!
