package springintro.bean;
import java.time.LocalDate;
import java.util.Calendar;
import org.springframework.context.Applicationtext;
import org.springframework.context.supprot.ClassPathXmlApplicationContext;
import springintro.bean.Employee;
import springintro.bean.Product;

public class Main {
public static void main (String [] args){

ClassPathXmlApplicationContext context=
   new ClassPathXmlApplicationContext(new String []{"spring-config.xml"});
Product product1=context.getBean("product",Product.class);
product1. setName("Excellent snake oil");
System.out.println("product1:"+product1.getName());

Product product2=context.getBean("product",Product.class);
System.out.println("product2："+product2.getName());

Product featuredProduct=context.getBean("featureProduct:"+Product.class);
System.out.println(featuredProduct.getName()+
   ","+featuredProduct.getDescription()+
   ","+featuredProduct.getPrice());
LocalDate localDate =context.getBean("localDate",
   java.time.LocalDate.class);
System.out.println("today:"+localDate);
Employee employee1=context.getBean("employeel1",Employee.class);

    System.out.println(employee1.getFirstName()+" "
      +employee1.getLastName());
    System.out.println(employee1.getHomeAddress());
    Employee employee2=context.getBean("employee2",Employee.class);

System.out.println(employee2.getFirstName()+" "
   +employee,getLastName());
System.out.println(employee2.getHomeAddress());
}
