Spring Bean六种作用域的适用场景和使用方式

@Component
public class Users {
   private User user;
    @Bean
    public User user1(){
       user= new User(1);
       user.setName("zcx");
       return user;
    }
}

@Controller
public class BeanScopesController {
    @Autowired
    private User user;
    public  User getUser(){
        User user1 = user;
        System.out.println(user1.toString()+"这是修改之前的");
        user1.setName("java");
        return  user1;
    }
}

@Controller
public class BeanScopesController2 {
    @Autowired
    private User user2;
    public  User getUser2(){
        User user = user2;
        return user;
    }
}

public class demo {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("spring-config.xml");
            BeanScopesController beanScopesController = context.getBean(BeanScopesController.class);
        System.out.println(beanScopesController.getUser().toString()+"这是第一个调用对象修改之后的");
        BeanScopesController2 beanScopesController2 = context.getBean(BeanScopesController2.class);
        System.out.println(beanScopesController2.getUser2().toString()+"这是第二个对象调用之后的");
    }
}

@Component
public class Users {
   private User user;
   @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
    @Bean
    public User user1(){
       user= new User(1);
       user.setName("zcx");
       return user;
    }
}
