What is difference between IoC and DI in spring?

Inversion of control is a design principle which helps to invert the control of object creation. Dependency Injection is a design pattern which implements IOC principle. … DI provides objects that an object needs.

What is Autowired in spring with example?

The @Autowired annotation provides more fine-grained control over where and how autowiring should be accomplished. The @Autowired annotation can be used to autowire bean on the setter method just like @Required annotation, constructor, a property or methods with arbitrary names and/or multiple arguments.

What is the IoC in spring?

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 are annotations in spring?

What is the benefit of using Spring framework?

Spring provides a lightweight container that can be activated without using web server or application server software. It gives good support for IoC and Dependency Injection results in loose coupling. The Spring Framework supports JDBC framework that improves productivity and reduces the error.
