What is IoC in spring with example?

Spring IoC is the mechanism to achieve loose-coupling between Objects dependencies. To achieve loose coupling and dynamic binding of the objects at runtime, objects dependencies are injected by other assembler objects. Spring IoC container provides us different ways to decouple the object dependencies.

What is IoC example?

With IoC: You can ask for “fruit”. You can get different fruits each time you get served. for example, apple, orange, or water melon. So, obviously, IoC is preferred when you like the varieties.

What is meant by IoC in spring?

In software engineering, inversion of control (IoC) is a programming technique in which object coupling is bound at run time by an assembler object and is typically not known at compile time using static analysis. In this spring tutorial, learn the difference between ioc and dependency injection in spring with example.

What are the types of IoC container in spring?

There are basically two types of IOC Containers in Spring:

• BeanFactory: BeanFactory is like a factory class that contains a collection of beans. It instantiates the bean whenever asked for by clients.
• ApplicationContext: The ApplicationContext interface is built on top of the BeanFactory interface.

What is difference between IOC and di in spring?

In DI design pattern, creation of object, injecting of the instance and life cycle management of the instance can be handled outside the code. In spring, Instantiation ,Injection and Lifecycle management are handled by IOC container.

What is dependency injection in Spring Boot?

Having understood the basic requirement behind dependency injection, lets now see an example of how to achieve that in Spring Boot. Dependency Injection is a core feature of Spring. To achieve dependency Injection, Spring keeps instantiated objects (also known as “beans”) when the application is run in a container called Application Context.

What is Spring IoC container?

The Spring IOC Container is a core of the Spring Framework, It will create the objects, wire them together, configure and manage complete life cycle from creation till destruction. The Spring Container uses DI ( Dependency Injection ) to manage the components that make up an application.

What is IoC container or DI container?

IoC Container (a.k.a. DI Container) is a framework for implementing automatic dependency injection. It manages object creation and it’s life-time, and also injects dependencies to the class.
