如何在配置为xml配置的spring集成项目中使用@RefreshScrop

<beans>
    <bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="locations">
            <list>
                <value>classpath:config.properties</value>
            </list>
        </property>
    </bean>
    <bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="properties" ref="configProperties"/>
    </bean>
</beans>

@Configuration
@RefreshScope
public class MyConfig {
    @Value("${my.property}")
    private String myProperty;

    // getter and setter
}

@SpringBootApplication
@EnableConfigServer
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

my.property=initial value

@RestController
public class MyController {
    @Autowired
    private MyConfig myConfig;

    @GetMapping("/myProperty")
    public String getMyProperty() {
        return myConfig.getMyProperty();
    }
}
