Previously in Guice 3 you could use a TypeListener to track when objects were directly instantiated by Guice (this doesn’t cover objects constructed inside of providers): http://google.github.io/guice/api-docs/latest/javadoc/com/google/inject/Binder.html#bindListener-com.google.inject.matcher.Matcher-com.google.inject.spi.TypeListener- In Guice 4 you can also use the new ProvisionListener API to track when objects are provisioned (ie. either instantiated by Guice itself or returned from a provider) http://google.github.io/guice/api-docs/latest/javadoc/com/google/inject/Binder.html#bindListener-com.google.inject.matcher.Matcher-com.google.inject.spi.ProvisionListener...- but you might have to do some de-duplication here since the same object could be provisioned multiple times. Another approach is to use a custom scope to record object use - you can then add a close method to the scope and call it when you want to dispose of those objects: https://github.com/google/guice/wiki/CustomScopes > 2.
