Spring Cloud：如何在@FeignClient中配置Hystrix

Question

I have following service:

@FeignClient(name = "person", fallback = FeignHystrixFallback.class)
public interface PersonService {

    @RequestMapping(value = "/find", method = RequestMethod.GET)
    Person findPerson(@RequestParam("name") String name);
}

How to change the default timeout and thread pool size?

Answer 1

There are other people that have run into this issue and have posted questions and have answers. The most relevant is this post:

Feign builder timeouts not working

If you are wanting to manage the configuration of Feign you would want to check out the Feign documentation looking at the "configuration" attribute of the @FeignClient annotation.

Answer 2

Set custom configuration for this interface

@FeignClient(name="person", configuration = FeignConfig.class)

and make configuration

public class FeignConfig {
    public static final int FIVE_SECONDS = 5000;

    @Bean
    public Request.Options options() {
        return new Request.Options(FIVE_SECONDS, FIVE_SECONDS);
    }
}
