Types of dependency injection patterns
The following are the types of dependency injections that could be injected into your application:
- Constructor-based dependency injection
- Setter-based dependency injection
Constructor-based dependency injection pattern
Dependency injection is a design pattern to resolve the dependencies of dependent classes, and dependencies are nothing but object attributes. The injector has to be constructed for the dependent objects by using one of the ways constructor injection or setter injection. A constructor injection is one of the ways of fulfilling these object attributes at the time of creation to instantiate the object. An object has a public constructor that takes dependent classes as constructor arguments to inject the dependencies. You can declare more than one constructor into the dependent class. Earlier, only the PicoContainer Framework is used a constructor-based dependency injection to resolve dependencies. Currently, the Spring Framework also supports...
