Sleuth將ScheduledExecutorService作爲LazyTraceExecutor封裝

Question

我已經在我的Sleuth啓用的Spring引導應用程序中定義了ScheduledExecutorService bean。當我從applicationContext中獲取這個bean時，sleuth已經用LazyTraceExecutorService包裝了它，這將拋出一個BeanNotOfRequiredTypeException異常。

@SpringBootTest(classes = { Config.class }) 
@RunWith(SpringRunner.class) 
public class SleuthTest { 
    @Autowired 
    private ApplicationContext applicationContext; 

    @Test 
    public void testScheduler() { 
     // this throws the BeanNotOfRequiredTypeException 
     applicationContext.getBean("executorService", ScheduledExecutorService.class); 
    } 
} 

@Configuration 
@EnableAutoConfiguration 
class Config { 
    @Bean 
    public ScheduledExecutorService executorService() { 
     // Sleuth will wrap this with LazyTraceExecutor, while I would expect a TraceableScheduledExecutorService 
     return new ScheduledThreadPoolExecutor(1); 
    } 
} 

我做錯了什麼或這是一個錯誤？

org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'executorService' is expected to be of type 'java.util.concurrent.ScheduledExecutorService' but was actually of type 'org.springframework.cloud.sleuth.instrument.async.LazyTraceExecutor'

Answer 1

我認爲這是BeanNotOfRequiredTypeException when using spring-statemachine and spring cloud slueth的重複。你有沒有嘗試過最新版本？
