In Spring, providing the values for the properties of a bean (i.e values to its member variables) is known as property injection. The properties of a bean are known as its dependencies. So it is also known as Dependency Injection.You may know that in Spring it is the responsibilty of the container to inject the dependencies into a bean when it creates the bean. This is also known as Inverse of Control (IOC).
Dependency Injection can be categorized into three categories :
1) Constructor injection
2) Setter Injection
3) Interface Injection
Spring supports only constructor and setter injection.
In Constructor injection values are injected using constructors of a bean and <constructor-arg> tags while in Setter injection values are injected using setter methods of a bean and <property> tags.
