DataKernel has an extremely lightweight DI with ground-breaking design principles. It supports nested scopes, singletons, object factories, modules and plugins which allow to transform graph of dependencies at startup time without any reflection.

The newest version!

package io.datakernel.di.core;

/**
 * A provider, unlike other DI frameworks, is just a version of {@link Injector#getInstance} with a baked in key.
 * If you need a function that returns a new object each time then you need to make your binding {@link Binding#transiently transient}.
 * 
 * The main reason for its existence is that it has a {@link io.datakernel.di.module.DefaultModule default generator}
 * for its binding so it can be fluently requested by {@link io.datakernel.di.annotation.Provides provider methods} etc.
 * 
 * Also it can be used for lazy dependency cycle resolution.
