How to use Spring XmlBeanFactory

Background

[wp_ad_camp_1]

XmlBeanFactory is one of Spring’s containers that provide dependency injection. Note that it has been deprecated already. This means that you should not use this in new development projects.

Software Environment

Windows 7 Professional SP1
Eclipse – Kepler Release
Java 1.7 (1.7.0_67 – Windows x86)
Spring Framework
- Spring Context 4.1.2

Bean Configuration File

A bean configration file is an XML file that contains all objects instantiated when the container starts.

The Main Class

import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;

import com.turreta.spring.ioc.bean.PersonBean;

public class MainClass {

    @SuppressWarnings("deprecation")
    public static void main(String[] args) {
        XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource(
                "allbeans.xml"));

        PersonBean mike = (PersonBean) factory.getBean("mike");
        System.out.println(mike.toString());
        
        PersonBean rock = (PersonBean) factory.getBean("rock");
        System.out.println(rock.toString());
        
        AnimalBean ant      = (AnimalBean) factory.getBean("ant");
        System.out.println(ant.toString());
        
        AnimalBean kangaroo = (AnimalBean) factory.getBean("kangaroo");
        System.out.println(kangaroo.toString());        
    }
}

import org.springframework.beans.factory.xml.XmlBeanFactory;
