I'm starting to learn about Spring Framework. I'm looking for a tutorial for beginner and can help me get started easily. The tutorial that I found online doesn't seem to fit for a beginner like me. The tutorials seem to assume that I know many things in advance already.
Can someone please advise a good tutorial? or a good book? I read that "Spring in Action" is a very good book but many says "Spring Live" is more appropriate for beginner?
My background: I do programming in JAVA using J2SE and I also do some JSP.
>>>>>>>>>>>>>>>>>>>>>>>>>> What aspect of Spring are you wanting to learn? And don't say all of it. .. >>>>>>>>>>>>>>>>>>>>>>>>>> Based on what you're saying, it seems that Spring framework is a pretty large framework that has many things inside depending on what you need. Are some parts really different from the others?
At this point, I want to explore the benefits that I can get by using the framework. I usually build web application parts using JSP, I read about Spring MVC idea and it seems like a very good idea to me. But I'm also looking for opportunity to share some of the Spring framework ideas to my coworker who specialized in back-end/ system programming.
Which talks about integrating with darn near anything.
This is just to show how huge "Spring" is. You need to figure what parts your are interested in a prioritize your learning. I'd start with the IoC container as understanding it is fundamental to the nature of spring. After that you may be interested in the MVC framework for web apps.
Oh and get the book "Spring in Action" [ March 03, 2008: Message edited by: Tim LeMaster ]

I personally don't like SpringMVC. I use Stripes but I do use Spring for my DAO/Service layers. Showing your co-workers how this might help them is a good idea. Don't expect oooooo's and ahhhhhh's right off the bat though. It takes a bit to see the benefits. But once you do it's tough to go back.

I just finished reading chapter 1 from "Spring in Action". =) I still don't know how to do things in Spring (probably it's better to start using it??). But I think it's a very good introduction about Spring core concepts (Dependency Injection and Aspect-Oriented Programming) for beginner like me than any tutorial that I can find online.
I already talked to one of my coworker about what I read, before our team gather together tomorrow for me (the new beginner) to give introduction about Spring and I found several things that I'm still confused about after trying to explain it to this one coworker:
(1.) Regarding Aspect-Oriented programming: This idea seems very appealing for me and very easy to explain to our organization that we can benefit from this.
Quote from Spring in Action:
Calls to system wide concerns such as logging and security are often scattered about in modules where those concerns are not their primary concern (CROSS-CUTTING CONCERNS). Even if it�s a single method call.Using AOP, system wide components encapsulates application components that they impact. This leaves the application components to focus on their specific functionality.
We have a system that is perfectly described by the statement above. But this part I still don't understand how:
System wide components encapsulates application components that they impact. This leaves the application components to focus on their specific functionality.
How does Spring do this? Is this something for me to figure out as I learn more?
(2.) I'm still confused how to explain dependency injection:
Why do we need Spring to do this? Can't we just have two application components, both having interfaces and implementations, interact between themselves?

This is called proxying. You have an bean, and a proxy (encapsulates application components) around that bean. When you get the bean via Spring, you may think that you are using the bean, but you're using the proxy. The bean doesn't know about it (this leaves the application components to focus on their specific functionality). If you are starting AOP, it may be a difficult concept at first, and maybe too soon for you to explain clearly. Read the chapter on AOP again, and try the samples from the book.
