Interface injection, where the dependency's interface provides an injector method that will inject the dependency into any client passed to it. In some frameworks, clients do not need to actively accept dependency injection at all. In Java, for example, reflection can make private attributes public when testing and inject services directly.

Google Guice (pronounced like "juice") [2] is an open-source software framework for the Java platform developed by Bob Lee and Kevin Bourrillion at Google and released under the Apache License. It provides support for dependency injection using annotations to configure Java objects. [ 3 ]
Dependency injection is a pattern where the container passes objects [4]: 128 by name to other objects, via either constructors, [4]: 128 properties, or factory methods. There are several ways to implement dependency injection: constructor-based dependency injection, setter-based dependency injection and field-based dependency injection. [56]
(Dependency injection is an example of the separate, specific idea of "inverting control over the implementations of dependencies" popularised by Java frameworks.) [4] Inversion of control is sometimes referred to as the "Hollywood Principle: Don't call us, we'll call you". [1]
Dependency hell is a colloquial term for the frustration of some software users who have installed software packages which have dependencies on specific versions of other software packages. [ 1 ] The dependency issue arises when several packages have dependencies on the same shared packages or libraries, but they depend on different and ...
The solution may be simpler with service locator (vs. dependency injection) in applications with well-structured component/service design. In these cases, the disadvantages may actually be considered as an advantage (e.g., no need to supply various dependencies to every class and maintain dependency configurations).
HK2 (Hundred-Kilobyte Kernel) is a light-weight and dynamic dependency injection framework and is a part of the GlassFish Application Server. HK2 complies with JSR 330 (Dependency Injection for Java). It has useful utilities for marking classes as services and interfaces as contracts. [1] Some of the features of HK2 DI Kernel are Custom scopes
Jakarta Contexts and Dependency Injection (CDI) is a specification to provide a dependency injection container; Jakarta Enterprise Beans ( EJB ) specification defines a set of lightweight APIs that an object container (the EJB container) will support in order to provide transactions (using JTA ), remote procedure calls (using RMI or RMI-IIOP ...
