Incomplete output stream error #228

Closed pgm-rookie closed 4 years ago

pgm-rookie commented 5 years ago

I updated spring-cloud-dependencies version to Greenwich.SR3, spring-boot-starter-parent version to 2.1.8.RELEASE.An exception occurred when service A(named saas-login) invoked service B(named saas-redis) through feign:

c.n.loadbalancer.reactive.LoadBalancerCommand - Got error java.io.IOException: Incomplete output stream when executed on server DESKTOP-JJLLNU5:8084
2019-10-09 10:52:16.211 [hystrix-saas-redis-79] DEBUG com.netflix.hystrix.AbstractCommand - Error executing HystrixCommand.run(). Proceeding to fallback logic ...
feign.RetryableException: Incomplete output stream executing POST http://saas-redis/saas-redis/cache/batchGetCache
……
Caused by: java.io.IOException: Incomplete output stream
……

I add a breakpoint on method of Service B and It was entered when Service A invoking this method in Service B, but Service A was not blocked and an exception has occurred, this may be due to asynchronous calls between services. But every thing was OK before I upgrading spring-cloud-dependencies version and spring-boot-starter-parent version. My feign client code is like below:

@FeignClient(value = "saas-redis",fallback = SaasRedisAPIFallback.class)
public interface SaasRedisAPI {

    @RequestMapping(value = "/saas-redis/cache/getCache", method = RequestMethod.POST )
    ResponseData<String> getCache(@RequestBody RequestData<CacheVO> requestData);

    @RequestMapping(value = "/saas-redis/cache/batchGetCache", method = RequestMethod.POST )
    ResponseData<Map<String,String>> batchGetCache(@RequestBody RequestData<List<CacheVO>> requestData);
}

How to invoke other services synchronously as before and how to invoke other services asynchronously on the newest spring cloud dependency version, THKS!

I'm afraid without a full stacktrace, we're not going to be much help.

move pom.xml to another previous version for Spring cloud from here: https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Greenwich-Release-Notes like this: Greenwich.RELEASE

Can you try with Hoxton.SR2? If you still experience the problem please provide a sample that reproduces the problem.

========================== Solution : updatedHttpHeaders.remove("content-length");

ResponseEntity responseEntity = client.executeRequest(request, updatedHttpHeaders);

Note : Check ur spring and cloud compatibility.
