java-javax-inject tck-1 JSR-330: Dependency Injection for Java

This package specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.

Many types depend on other types. For example, a Stopwatch might depend on a TimeSource. The types on which a type depends are known as its dependencies. The process of finding an instance of a dependency to use at run time is known as resolving the dependency. If no such instance can be found, the dependency is said to be unsatisfied, and the application is broken.
