In object-oriented system, the object encapsulates the data and the processing of the data, the dependency of the object is often embodied in the dependence on the data and the method. These dependencies can be done by giving the object's dependency injection to the framework or IOC container, which is very valuable to hand over the control from the specific object, which can improve the testability of the

This article mainly explains MEF as an IOC container, and there are very many IOC containers available in. NET, such as Castlewindsor,unity,autofac,objectbuilder,structuremap, Spring.net, these third-party tools are different, but the function is generally the same, most need to pre-match interface and implementation (through code or configuration file), and then

Spring is often used in projects where an interview was asked how spring loaded the bean, and I answered it by Java reflection, without hesitation. But the interviewer is skeptical, make me a bit blind, look back is also read a lot of information. Preliminary read the source code of the next SPRINGIOC, with a large number of template mode, good ni forgive, I do not see the special understanding, but the basic ability to understand the principles of the IOC

1. What is SpringSpring is an open-source, lightweight framework designed to streamline enterprise application development and reduce intrusion;The IOC and AOP applications provided by spring can minimize the coupling of components, i.e. decoupling to facilitate future maintenance and upgrades of the system;Spring provides a holistic solution for the system, and developers can take advantage of the capabilities it provides, as well as integrate with t
This article discusses how to extend the bean functionality in spring in the spring life cycle.Expansion of the containerIn general, developers do not need to inherit ApplicationContext to implement their own subclass extension functionality. But the spring IOC container can actually add some functionality by implementing an interface. These interfaces are described below.PassBeanPostProcessorDefining beans
Preface
The creation process of Spring IOC container is researched and analyzed based on its source code. It mainly involves the creation process of BeanFactory and Bean parsing and registration process, bean instantiation process and IOC construction process such as ClassPathXmlApplicationContext.

Two What is the Castle IOC container
Windsor is an IOC container for castle. It is built on top of microkernel, powerful enough to detect classes and understand what parameters are needed to use them, detect work dependencies between types a

As mentioned above, spring uses the configuration file to describe the relationship between bean and bean, and the IOC container will instantiate these beans. The program just used applicationcontext, in fact, it is built on beanfactory, that is, beanfactory is the underlying implementation of Spring IoC containers. it provides the basic functions of
Concept:The IOC (inversion of control) controlled inversion, which would have been a dependency between objects managed by the application, is now handed over to the container management, which is called control reversal, which is given to the IOC container, the spring IOC
