In the above bean "eMail" configuration, two property marked in background colour green is Dependency Injection where we are injecting the configuration values into the class com.lnt.infotech.EMail.
---------------------------------------------------------------------
SendEmail.java
package com.lnt.infotech;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SendEmail {
public static void main(String[] args) {
System.out.println("--------Start---------");
ApplicationContext context = new ClassPathXmlApplicationContext("springapp-servlet.xml");
EMail mm = (EMail) context.getBean("eMail");
mm.sendMail("Prajith", "This is text content");
}
}
In the above code we are just getting the object of class EMail.java from the WebApplicationContext.xml(spring-app.xml) and accessing the method sendMail.
