What are the different ways to achieve the spring IoC?
The Spring Framework provides three ways to configure beans for use in your application. Annotation-based configuration: By using @Service or @Component annotations. Scope details can be provided with the @Scope annotation. XML-based configuration: By creating a Spring configuration XML file to configure the beans.

How many ways can we create an IoC container in spring?
There are two types of IoC containers. They are: BeanFactory. Application context.
How does Spring achieve the DI or IoC pattern?
Spring implements DI using an XML configuration file or annotations. Dependency Injection is a pattern through which IoC is implemented and the act of connecting objects to other objects or injecting objects into objects is done by the container rather than the object itself.
What are the different types of IoC?
There are basically two types of IOC containers in Spring:
- BeanFactory: BeanFactory is like a factory class that contains a collection of beans. Instantiates the bean when requested by clients.
- ApplicationContext: The ApplicationContext interface is built on top of the BeanFactory interface.
What is the role of the IoC container in Spring?
The Spring IoC container is the core of the Spring Framework. The container will create the objects, connect them, configure them, and manage their entire lifecycle from creation to destruction. The Spring container uses dependency injection (DI) to manage the components that make up an application.
What is the current core container in Spring?
What is the advantage of IoC?
Advantages and risks of using IoC Better code clarity: It is clear at first glance what dependencies the class (object) requires for its functionality. Simpler application structure: The application of IoC principles leads to the creation of reusable components.
How does container IoC work in spring?
The IoC container gets information from the XML file and works accordingly. The main tasks performed by the IoC container are: There are two types of IoC containers. They are: The org.springframework.beans.factory. BeanFactory and org.springframework.context. The ApplicationContext interfaces act as the IoC container.
What is the difference between IOC and dependency injection in spring?
Dependency Injection in Spring 1 6.1. Setter injection. Setter-based DI is done by calling setter methods on your beans after calling a no-argument constructor or no-argument static factory method to instantiate your bean. 2 6.2. Builder injection. 3 6.3. interface injection.
Configuration metadata can be represented using XML, Java annotations, or Java code. The following diagram represents a high-level view of how Spring works. The Spring IoC container makes use of Java POJO classes and configuration metadata to produce a fully configured and executable system or application.
What is the interface that acts as IoC container?
The ApplicationContext interfaces act as the IoC container. The ApplicationContext interface is built on top of the BeanFactory interface.
