Dependency injection is a pattern through which to implement IoC, where the control being inverted is the setting of object’s dependencies.
The act of connecting objects with other objects, or “injecting” objects into other objects, is done by an assembler rather than by the objects themselves.
To set the item attribute in the example above, we can use metadata. Then, the container will read this metadata and use it to assemble beans at runtime.
Dependency Injection in Spring can be done through constructors, setters or fields.
