I've also added a way to do injection the other way around: from Guice into MC. | AbstractBeanMetaData guicePlugin = new AbstractBeanMetaData("GuicePlugin", GuiceKernelRegistryEntryPlugin.class.getName()); | AbstractConstructorMetaData constructor = new AbstractConstructorMetaData(); | AbstractArrayMetaData arrayMetaData = new AbstractArrayMetaData(); | final Singleton singleton = new Singleton(); | Module module = new AbstractModule() | { | protected void configure() | { | bind(Singleton.class).toInstance(singleton); | } | }; | arrayMetaData.add(new AbstractValueMetaData(module)); | constructor.setParameters(Collections.singletonList((ParameterMetaData)new AbstractParameterMetaData(arrayMetaData))); | guicePlugin.setConstructor(constructor); | controller.install(guicePlugin); | | BeanMetaData holderBean = new AbstractBeanMetaData("holder", SingletonHolder.class.getName()); | controller.install(holderBean); | | ControllerContext holderContext = controller.getInstalledContext("holder"); | assertNotNull(holderContext); | SingletonHolder holder = (SingletonHolder)holderContext.getTarget(); | assertNotNull(holder); | assertEquals(singleton, holder.getSingleton()); | | The detail is in GuiceKernelRegistryEntryPlugin, which acts as a middle man between MC registry and Guice Injector instance. | public class GuiceKernelRegistryEntryPlugin implements KernelRegistryPlugin | { | private Injector injector; | | public GuiceKernelRegistryEntryPlugin(Module... modules) | { | injector = Guice.createInjector(modules); | } | | public void destroy() | { | injector = null; | } | | public KernelRegistryEntry getEntry(Object name) | { | KernelRegistryEntry entry = null; | try | { | if (name instanceof Class<?>) | { | Class<?> clazz = (Class<?>)name; | entry = new AbstractKernelRegistryEntry(name, injector.getInstance(clazz)); | } | else if (name instanceof Key) | { | Key<?> key = (Key<?>)name; | entry = new AbstractKernelRegistryEntry(name, injector.getInstance(key)); | } | } | catch (Exception ignored) | { | } | return entry; | } | } | MC documentation has already been updated with this new Guice-int module.
