Hystrix 断路器不选择 application.yml

Question

Hystrx 断路器不会从 application.yml 文件中选择值。我需要从 application.yml 文件中获取 timeoutInMilliseconds、errorThresholdPercentage。当我运行程序时，这些属性没有影响，因为它们没有被拾取。

import java.net.URI;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;

@Service
public class BookService {
      RestTemplate restTemplate;
      //Calling the service
     @HystrixCommand
      public String readingList(int flag) {
        restTemplate = new RestTemplate();
         URI uri = URI.create("http://localhost:8090/recommended/"+flag);
        return this.restTemplate.getForObject(uri, String.class);
      }

      public String reliable(int flag) {
        return "Cloud Native Java (O'Reilly)";
      }

}

这是 application.yml 文件

hystrix:
  command:
    reliable:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 6000
          strategy: SEMAPHORE
        circuitBreaker:
          errorThresholdPercentage: 70

Answer 1

您需要使用 @HystrixCommand() 注释您的方法并给出 commandKey = "reliable"。

@HystricCommand(commandKey="reliable")
public String reliable(int flag) {
    return "Cloud Native Java (O'Reilly)";
  }
