Factory Bean
Spring Inversion of Control (IoC ) also known as
Dependency Injection (DI ) is a process by which
objects define their dependencies with collaborating objects.
This example shows invoking an instance factory method on a bean instance.
package com.bethecoder.tutorials.spring3.basic; public class Foo { public Bar createBar () { return new Bar () ; } public static class Bar { } }
package com.bethecoder.tutorials.spring3.tests.factory; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.ClassPathResource; import com.bethecoder.tutorials.spring3.basic.Foo; public class FactoryBean { /** * @param args */ public static void main ( String [] args ) { XmlBeanFactory factory = new XmlBeanFactory ( new ClassPathResource ( "factory_bean.xml" )) ; Foo foo = ( Foo ) factory.getBean ( "foo" ) ; System.out.println ( foo ) ; Foo.Bar bar = ( Foo.Bar ) factory.getBean ( "bar" ) ; System.out.println ( bar ) ; } }
