The WireModule
should enclose all modules in your application:
Guice.createInjector( new WireModule( bootModule, configModule, mainModule ) );Use the
ChildWireModule
when you want to wire child injectors:
injector.createChildInjector( new ChildWireModule( serviceModule, subModule ) );
LocatorWiring
which can supply the following bindings via the BeanLocator
:
@Inject MyType bean @Inject @Named("hint") MyType namedBean @Inject @MyQualifier MyType qualifiedBean @Inject Provider<MyType> beanProvider
@Inject @Named("${my.property.name}") File file // supports basic type conversion @Inject @Named("${my.property.name:-http://example.org/}") URL url // can give default in case property is not set @Inject @Named("${my.property.name:-development}") MyType bean // can be used to pick specific @Named beans @Inject @Named("my.property.name") int port // shorthand syntax
You can bind your configuration at runtime as follows:
bind( ParameterKeys.PROPERTIES
).toInstance( myConfiguration ); // multiple bindings are merged into one view
BeanLocator
.
They are also lazy, meaning instances are created as you access elements of the collection; the elements are then re-used for the same collection.
@Inject List<MyType> list
@Inject List<Provider<MyType>> providers
@Inject Iterable<BeanEntry
<MyQualifier, MyType>> entries // gives access to additional metadata
@Inject Map<String, MyType> stringMap // strings are taken from @Named values @Inject Map<Named, MyType> namedMap @Inject Map<MyQualifier, MyType> qualifiedMap @Inject Map<String, Provider<MyType>> providerMap
