Hello Guy's
Bellow code will help you to initialize method using Spring-beans.Here, I am using init and destroy method as attribute in bean configuration for bean to perform assigned actions upon initialization and destruction.
Follow the bellow steps to develop your own project :

Step :1
Create FindnerdService class and put bellow code .

package com.bhagwan.services;
 
public class FindnerdService
{
        String propertyMessage;
 
        public String getMessage() {
          return propertyMessage;
        }
 
        public void setMessage(String propertyMessage) {
          this.propertyMessage = propertyMessage;
        }
 
        public void initIt() throws Exception {
          System.out.println("Init method after properties are set : " + propertyMessage);
        }
 
        public void cleanUp() throws Exception {
          System.out.println("Spring Container is destroy!");
        }
 
}

Step :2
Create Spring-Service.xml

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
 
        <bean id="springService" class="com.bhagwan.services.FindnerdService" 
                init-method="initIt" destroy-method="cleanUp">
 
                <property name="propertyMessage" value="property message" />
        </bean>
 
</beans>

Step :3
Create App class and put bellow code

package com.bhagwan.common;
 
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
 
import com.bhagwan.services.FindnerdService;
 
public class App 
{
    public static void main( String[] args )
    {
        ConfigurableApplicationContext context = 
                new ClassPathXmlApplicationContext(new String[] {"Spring-Service.xml"});
 
        FindnerdService findnerd = (FindnerdService)context.getBean("springService");
 
        System.out.println(findnerd);
 
        context.close();
    }
}

Note : Please run App class and enjoy
