  //定义javaBean
  

  import org.springframework.context.annotation.Scope;

  import org.springframework.stereotype.Component;

  @Component

  @Scope("prototype")

  public class Person {

  private int id;

  private String name;

  public int getId() {

  return id;

  }

  public void setId(int id) {

  this.id = id;

  }

  public String getName() {

  return name;

  }

  public void setName(String name) {

  this.name = name;

  }

  }

  //测试类

  import org.springframework.context.ApplicationContext;

  import org.springframework.context.support.ClassPathXmlApplicationContext;

  
  

  /**

   * Hello world!

   *

   */

  public class App 

  {

      public static void main( String[] args )

      {

          ApplicationContext appContext = new ClassPathXmlApplicationContext("/spring.xml");

          Person p1 = appContext.getBean(Person.class);

          System.out.println("p1's identityHashCode is " + System.identityHashCode(p1));

          

          Person p2 = appContext.getBean(Person.class);

          System.out.println("p2's identityHashCode is " + System.identityHashCode(p2));

          

      }

  }

  @Scope("")类型不同,作用域范围不同
