//定義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;
}
}
//測試類
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("")類型不同,作用域范圍不同
