Annotation based Bean Scope Example

Step 1. Create model class, in which put some attribute and make setter and getter methods for these attribute and also define a method that will be called from main class to get object info.

package com.ps.model;

import org.springframework.context.annotation.Scope;

import org.springframework.stereotype.Service;

@Service

@Scope("prototype")

public class JobSeeker {

       private int jobSeekerId;

       private String jobSeekerName;

      

       public int getJobSeekerId() {

             return jobSeekerId;

       }

       public void setJobSeekerId(int jobSeekerId) {

             this.jobSeekerId = jobSeekerId;

       }

       public String getJobSeekerName() {

             return jobSeekerName;

       }

       public void setJobSeekerName(String jobSeekerName) {

             this.jobSeekerName = jobSeekerName;

       }

      

       public void display()

       {

             System.out.println("Id: "+this.getJobSeekerId()+" and Name: "+this.getJobSeekerName());

       }

      

}

Step 2. Create spring bean configuration file that contains metadata of beans.

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-2.5.xsd">

      

       <context:component-scan base-package="com.ps.model" />

</beans>

Step 3. Create main class from where spring container will initialize the container and all beans objects.

package com.ps.model;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestBeanScope {

               public static void main(String[] args) {

                             

                              ApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml");

                             

                              JobSeeker jsObj=(JobSeeker) ctx.getBean(JobSeeker.class);

                              jsObj.setJobSeekerId(1000);

                              jsObj.setJobSeekerName("Heera");

                              jsObj.display();

                             

                              JobSeeker jsObj2=(JobSeeker) ctx.getBean(JobSeeker.class);

                              jsObj2.setJobSeekerId(1001);

                              jsObj2.setJobSeekerName("Babu");

                              jsObj2.display();

               }

}

Sample output

Id: 1000 and Name: Heera

Id: 1001 and Name: Babu
