Java 如何在SpringBoot中定义并注入带有注释的bean？

我的bean定义如下所示：

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter { 
    @Bean
    public ExecutorService executorService() {
        return Executors.newFixedThreadPool(5);
    }   
}

@Endpoint
public class SOAPEndpoint {
    @Autowired
    private ExecutorService executor;
}

我想在另一个类中使用这个bean，如下所示：

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter { 
    @Bean
    public ExecutorService executorService() {
        return Executors.newFixedThreadPool(5);
    }   
}

@Endpoint
public class SOAPEndpoint {
    @Autowired
    private ExecutorService executor;
}

这是真的吗？我很好奇，因为输出说注入的实例的池大小是0而不是5

System.out.println(executor);

java.util.concurrent。ThreadPoolExecutor@1058b8a[正在运行，池大小=0，活动线程=0，排队任务=0，已完成任务=0]
