['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.']

The main difference between the web containers and application server is that most web containers such as Apache Tomcat implements only basic JSR like Servlet, JSP, JSTL wheres Application servers implements the entire Java EE Specification. Every application server contains web container.

The scope of the Spring singleton is best described as per container and per bean. This means that if you define one bean for a particular class in a single Spring container, then the Spring container will create one and only one instance of the class defined by that bean definition.

The difference between them is, @component is used to annotate compound classes, @Repository is a marker for automatic exception translation in the persistence layer, for service layer we need to use @service. You can refer Spring Documentation to know more.

Inversion of Control (IoC) is a design principle (although, some people refer to it as a pattern). As the name suggests, it is used to invert different kinds of controls in object-oriented design to achieve loose coupling. ... IoC is all about inverting the control.

The Spring IoC container The IoC container receives metadata from either an XML file, Java annotations, or Java code. The container gets its instructions on what objects to instantiate, configure, and assemble from simple Plain Old Java Objects (POJO) by reading the configuration metadata provided.

8.6 Proxying mechanisms. Spring AOP uses either JDK dynamic proxies or CGLIB to create the proxy for a given target object. (JDK dynamic proxies are preferred whenever you have a choice). If the target object to be proxied implements at least one interface then a JDK dynamic proxy will be used.

Both approaches aim to register target type in Spring container. The difference is that @Bean is applicable to methods, whereas @Component is applicable to types. Therefore when you use @Bean annotation you control instance creation logic in method's body (see example above). With @Component annotation you cannot.

Spring bean is managed by Spring IOC, Java Bean is not. Java Bean is always serializable, Spring Bean doesn't need to. Java Bean must have a default no-arg constructor, Spring Bean doesn't need to. A Java object can be a JavaBean, a POJO and a Spring bean all at the same time.

Input/output completion port (IOCP) is an API for performing multiple simultaneous asynchronous input/output operations in Windows NT versions 3.5 and later, AIX and on Solaris 10 and later. An input/output completion port object is created and associated with a number of sockets or file handles.

No, @Controller is not the same as @Service , although they both are specializations of @Component , making them both candidates for discovery by classpath scanning. The @Service annotation is used in your service layer, and @Controller is for Spring MVC controllers in your presentation layer.

The Spring support for integration testing enables one to perform integration testing without actually deploying the application server or connecting to other dependent infrastructures. This is a huge plus point because it enables us to test the wiring of Spring IoC container contexts.
