Say we have a BookService that helps us look up all Book objects: public class Book Let's create a simple web page that shows a list of books saved in our application. Package import import .JSP pages rely on the JavaServer Pages Standard Tag Library (JSTL) to provide common templating features like branching, iterating and formatting, and it even provides a set of predefined functions. userName property value will be set to jai. At the time of object creation IoC container sets the bean propoerties value defined in spring configuration file i.e. We have to pass beanId in the getBean() method. Then get the HelloWorld bean object from ApplicationContext by using getBean() method. Framework creates the ApplicationContext object by using spring configuration file. Next create the Test.java class as a main program. This id will be used later to get the bean object from ApplicationContext object. Here we define HelloWorld.java bean with id helloWorld. Next create a spring configuration file which defines the bean and its properties. Example explanation:įirst create a java bean class named “HelloWorld.java” which have a propoerty userName and a method sayHello. Spring uses singleton design pattern for beans, so every spring bean is singleton class by default. Spring IOC container is responsible for creating bean objects and dependency injection.ģ.

TestBean testBean = (TestBean) context.getBean('testBeanId') Ģ. New ClassPathXmlApplicationContext('spring configuration file') ApplicationContext context = new ClassPathXmlApplicationContext ( 'spring configuration file' )
