spring-cloud

问题 Since Spring Cloud team has abandoned development of Zuul module, we are moving to Spring Cloud Gateway or Zuul2 but I believe Zuul2 needs a lot of changes in the architecture and needs big changes in the microservices(correct me if i'm wrong), can anyone gives a recommendation on zuul2 or Spring-Cloud-Gateway, has anyone or you know any big player in tech using Spring-Cloud-Gateway? 回答1: Zuul1 is blocking whereas Zuul2 and spring cloud gateway are non-blocking and this is a major performance

问题 I am using two Eureka server in spring cloud to replicate each other, when I open the page at http://localhost:8761, I saw this message: RENEWALS ARE LESSER THAN THE THRESHOLD. THE SELF PRESERVATION MODE IS TURNED OFF.THIS MAY NOT PROTECT INSTANCE EXPIRY IN CASE OF NETWORK/OTHER PROBLEMS. The eureka application.xml is this: server: port: ${server.instance.port:5678} spring: application: name: nodeservice sidecar: port: ${nodeserver.instance.port:3000} health-uri: http://localhost:${nodeserver

问题 I have a monitoring app wherein I am running a fixedRate task. This is pulling in a config parameter configured with Consul. I want to pull in updated configuration, so I added @RefreshScope. But as soon as I update the config value on Consul, the fixedRate task stops running. @Service @RefreshScope public class MonitorService { @Autowired private AppConfig appConfig; @PostConstruct public void postConstRun() { System.out.println(appConfig.getMonitorConfig()); } @Scheduled(fixedRate = 1000)

问题 I use Spring Cloud Data Flow to set up a stream that read a CSV file, transform it using a custom processor and log it : stream create --name testsourcecsv --definition "file --mode=lines --directory=D:/toto/ --file.filename-pattern=adresses-28.csv --maxMessages=1000 | csvToMap --spring.cloud.stream.bindings.output.content-type=application/json | log --spring.cloud.stream.bindings.input.content-type=application/json" --deploy The file and csvToMap applications work fine, but in the log

问题 Using spring-mvc annotations, how can I define an @FeignClient that can POST form-url-encoded? 回答1: Use form encoder for feign: https://github.com/OpenFeign/feign-form and your feign configuration can look like this: class CoreFeignConfiguration { @Autowired private ObjectFactory<HttpMessageConverters> messageConverters @Bean @Primary @Scope(SCOPE_PROTOTYPE) Encoder feignFormEncoder() { new FormEncoder(new SpringEncoder(this.messageConverters)) } } Then, the client can be mapped like this:

问题 I am looking for a way to intercept the @Input annotation and add an interceptor for my Subscribable Channel Something like below @Around("@annotation(org.springframework.cloud.stream.annotation.Input)") public Object interceptInput(ProceedingJoinPoint joinPoint) throws Throwable { LOG.debug("Intercepted @Input from method : {}", joinPoint.getSignature()); Object returnValue = null; try { returnValue = joinPoint.proceed(); // add the interceptor for input channel } catch (Exception e) { LOG
