Spring Cloud：如何在@FeignClient中配置Hystrix

Question

我有以下服务：

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

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

如何更改默认超时和线程池大小？

还有其他人遇到过这个问题并发布了问题并得到了答案。最相关的是这篇文章：

如果您想要管理Feign的配置，您可以查看Feign文档，查看@FeignClient注释的“configuration”属性。

Answer 2

设置此接口的自定义配置

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

并进行配置

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

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