Guice - Just-in-time Bindings
Google Guice - Just-In-Time Bindings
As bindings are defined in Binding Module, Guice uses them whenever it needs to inject dependencies. In case bindings are not present, it can attempt to create just-in-time bindings. Bindings present in binding module are called exppcit bindings and are of higher precedence whereas just-in-time bindings are called imppcit bindings. If both type of bindings are present, exppcit bindings are considered for mapping.
Following are the examples of three types of Just-in-time bindings.
| Binding Type | Description |
|---|---|
| Non-private, No-argument constructors are epgible for just-in-time bindings. Another way is to annotate a constructor with @Inject annotation. | |
| @ImplementedBy annotation tells the guice about the implementation class. No binding is required in Binding Module in such a case. | |
| @ProvidedBy annotation tells the guice about the provider of implementation class. No binding is required in Binding Module in such a case. |
