There are two distinct types of spring containers as mentioned below.
Spring container explained.

Dynamic proxies wrap the actual objects you use and intercept method calls allowing to apply aop advices.
The container can be turned into a partially compliant ejb enterprise javabeans 3 0 container by means of the pitchfork project.
They can communicate with each other through well defined channels.
The application context is spring s advanced container.
The spring container uses di to manage the components that make up an application.
These objects are called spring beans which we will discuss in the next chapter.
Related interfaces such as beanfactoryaware initializingbean disposablebean can provide callbacks which can be configured for the different phases of the spring bean s life cycle.
As per the spring documentation here the beanfactory interface is the central ioc container interface in spring.
The configuration metadata is represented in xml java annotations or java code.
Spring offers a range of aware interfaces that allow beans to indicate to the container that they require a certain infrastructure dependency.
Java lang reflect proxy in the java sdk.
The spring container provides a consistent mechanism to configure applications and integrates with almost all java environments from small scale applications to large enterprise applications.
Each interface will require you to implement a method to inject the dependency in bean.
The container will create the objects wire them together configure them and manage their complete life cycle from creation till destruction.
The spring container is responsible for instantiating configuring and assembling the spring beans.
Container is used to describe any component that can contain other components inside itself.
Additionally it adds more enterprise specific functionality such as the ability to resolve textual messages from a properties file and the ability to publish application events to interested event listeners.
United states restricted mode.
All containers are run by a single operating system kernel and therefore use fewer resources than virtual machines.
Containers are isolated from one another and bundle their own software libraries and configuration files.
Similar to beanfactory it can load bean definitions wire beans together and dispense beans upon request.
This is the simplest container providing basic support for dependency injection and defined by the org springframework beans factory beanfactory interface.
Actually by default spring does not do any bytecode postprocessing neither for xml nor annotation configured beans.
The spring container is at the core of the spring framework.
The service has both free and premium tiers.
Instead relevant beans are wrapped into dynamic proxies see e g.
