just start.

Hello guys...

i just started to learn Spring2. according to the spring2, it looks like the most advantage of spring is 'Dependency Injection'.

i am reading Spring in action. but i stuck from the first chapter.

/*
BeanFactory factory = new XmlBeanFactory(new FileSystemResource("classes/com/test/chap1/knight/knight.xml"));


// TODO Auto-generated method stub
Knight knight =
(Knight) factory.getBean("knight");
*/

// What's the difference between this and above.
Knight knight = new KnightOfTheRoundTable("Bedivere");


the commented line is what is in book. the last line is what i thought and work as same as book.
what's the difference between book and the last line?

I suggest you just continue reading and at least finish the chapter about dependency injection.

Both do exactly the same thing, just one demonstrates the Spring way.

Knight knight =
(Knight) factory.getBean("knight");

Gets an instance of Knight from the configured BeanFactory.

Knight knight = new KnightOfTheRoundTable("Bedivere");

Returns a Knight as per a stock std instantiation.
