Spring BeanFactory example

 

Spring BeanFactory container

This is the simplest container providing basic support for Dependency Injection and defined by the Spring org.springframework.beans.factory.BeanFactory interface. The BeanFactory and related interfaces, such as BeanFactoryAware, InitializingBean, DisposableBean, are still present in Spring for the purposes of backward compatibility with the large number of third-party frameworks that integrate with Spring

1. XML Based configuration

http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
    <bean id="studentBean" class="com.vinod.test.Student">

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

import org.springframework.core.io.ClassPathResource;
public class BeanFactoryExample {

    public static void main(String[] args) {
        XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource(
                "spring-core.xml"));
        Student obj = (Student) factory.getBean("studentBean");
        System.out.println(obj.getClass().getName());
