The phrase "inversion of control" has separately also come to be used in the community of Java programmers to refer specifically to the patterns of dependency injection (passing to objects the services they need) that occur with "IoC containers" in Java frameworks such as the Spring Framework. [4]
Under inversion of control, the framework first constructs an object (such as a controller), and then passes control flow to it. With dependency injection, the framework also instantiates the dependencies declared by the application object (often in the constructor method's parameters), and passes the dependencies into the object.
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).
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]
In object-oriented design, the dependency inversion principle is a specific methodology for loosely coupled software modules.When following this principle, the conventional dependency relationships established from high-level, policy-setting modules to low-level, dependency modules are reversed, thus rendering high-level modules independent of the low-level module implementation details.
The project was founded by Hamilton Verissimo de Oliveira (aka "Hammett"), who was a member of the Apache Avalon and the Apache Excalibur projects. Keenly interested in the development of an inversion of control container, after he resigned from Avalon and became disillusioned with Excalibur, he went on to develop and release his own for the .NET platform.
In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.
