Published: April 1, 2010 , Updated: August 16, 2011 , Author: mkyong

The Spring framework , created by Rod Johnson, is an extremely powerful Inversion of control(IoC) framework to helps decouple your project components’ dependencies.

In this series of tutorials, it’s provides many step by step examples and explanations on using Spring framework.

New Spring 3.0 Tutorials (23/06/2011)
Added many Spring 3.0 tutorials on using Spring EL, JavaConfig, AspectJ and Spring Object/XML mapping (oxm). For what new in Spring 3.0, you can refer to this official Spring 3.0 references.

The constructor injection argument type ambiguities issue is always happened in a bean which contains multiple constructor methods with many arguments.

Bean Basic

All the classes you need to use in Spring Ioc container are consider “bean”, and declared in Spring bean configuration file or via annotation.

Spring Autowiring by Type
If data type of a bean is compatible with the data type of other bean property, auto wire it.
Spring Autowiring by Name
If the name of a bean is same as the name of other bean property, auto wire it.
Spring Autowiring by Constructor
Actually, it’s autowiring by Type in constructor argument.
Spring Autowiring by AutoDetect
It means chooses “autowire by constructor” if default constructor is found, otherwise uses “autowire by type”.
Spring Autowiring with @Autowired annotation
Examples to show how to define ‘auto-wiring’ modes in annotation.
Spring Autowiring @Qualifier example

Hi – One of best tutorials website I have ever seen
I appreciate you Spring knowledge and simplicity of posts. I am looking for an article that explains “Different ways to load Spring contexts”. For example – Most of us aware of loading context through web.xml in web applications. I encountered this issue when looking for my non-web application and came across SpringContextResourceAdapter class.
So, it would be great if you can provide some best practices around this topic.
Thank you
-Nitin

Hi MKyong,
Thank you very much and I am leaning a lots from your web site. Regarding EJB tutorial, please write EJB 3.0, as I know there are huge difference between them. Also I think you should contact http://headfirstlabs.com/, they are looking for person like you to write EJB 3.0. Your learning courses are very clear to reader through unique and easy understanding excellent examples.
You are our field expert and our time hero!

MD Jafar :
Thanks for these examples,
I have a small doubt regarding your statement about a bean
according to you
“All the classes you need to use in Spring Ioc container are consider “bean””
are beans the classes or the objects created by IOC containers to manage our application.
I am new to this framework and i have this question,am really sorry if it sounds stupid.

- August 20, 2011 at 12:04 am
  mkyong :
  “bean” represent your “class” or “object”, not belong to Spring , it’s Java naming.
