willard-kali opened a new issue #1092: Use RestTemplate to request another micro service in dispatcher occurred Thread blocked VertxException URL: https://github.com/apache/servicecomb-java-chassis/issues/1092 I followed by https://github.com/huaweicse/cse-java-chassis-samples/tree/master/porter/gateway-service/src/main/java/com/huawei/cse/porter/gateway in UiDispatcher, I added like this. ``` public class UiDispatcher extends AbstractEdgeDispatcher { ... private RestTemplate restTemplate = RestTemplateBuilder.create(); @Override public int getOrder(){...} @Override public void init(Router router) { ... router.routeWithRegex(regex).failureHandler(this::onFailure).handler(this::onRequest); } protected void onRequest(RoutingContext context) { ... String sessionInfo = restTemplate.getForObject(requestUrl, String.class); if (isValid(sessionInfo)) {...} .... HttpClientRequest clietRequest = httpClient.request(...); .... } ``` After a few click, it occurred exception and blocked. error message: ``` 2019-02-12 17:25:07,309 [WARN] Thread Thread[transport-vert.x-eventloop-thread-2,5,main] has been blocked for 36189 ms, time limit is 2000 io.vertx.core.impl.BlockedThreadChecker$1.run(BlockedThreadChecker.java:52) io.vertx.core.VertxException: Thread blocked at sun.misc.Unsafe.park(Native Method) at java.util.concurrent.locks.LockSupport.park(LockSupport.java:175) at java.util.concurrent.locks.AbstractQueuedSynchronizer.parkAndCheckInterrupt(AbstractQueuedSynchronizer.java:836) at java.util.concurrent.locks.AbstractQueuedSynchronizer.doAcquireSharedInterruptibly(AbstractQueuedSynchronizer.java:997) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquireSharedInterruptibly(AbstractQueuedSynchronizer.java:1304) at java.util.concurrent.CountDownLatch.await(CountDownLatch.java:231) at org.apache.servicecomb.core.provider.consumer.SyncResponseExecutor.waitResponse(SyncResponseExecutor.java:53) at org.apache.servicecomb.core.provider.consumer.InvokerUtils.innerSyncInvoke(InvokerUtils.java:75) at org.apache.servicecomb.provider.springmvc.reference.CseClientHttpRequest.doInvoke(CseClientHttpRequest.java:204) at org.apache.servicecomb.provider.springmvc.reference.CseClientHttpRequest.invoke(CseClientHttpRequest.java:194) at org.apache.servicecomb.provider.springmvc.reference.CseClientHttpRequest.execute(CseClientHttpRequest.java:146) at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:660) at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:621) at org.springframework.web.client.RestTemplate.getForObject(RestTemplate.java:295) at org.apache.servicecomb.provider.springmvc.reference.RestTemplateWrapper.getForObject(RestTemplateWrapper.java:79) ... ``` is there anything wrong in my code?
