FeignClient Hystrix 超时测试

1.注解形式，可以精确到服务，也可以动态根据方法名称设置超时

@FeignClient(name = "xxx-im", url = "${svc.xxx.im}",/*configuration=DisableHystrixConfiguration.class, */fallback = ProductClientHystrix.class)
public interface IProductService {

   //
   @RequestMapping(value = "/product/queryCategoriesCodeByProductCode", method = RequestMethod.POST)
   String queryCategoriesCodeByProductCode(@RequestBody String productCode);

   @RequestMapping(value = "/product/queryMaxBasicPriceByPizzaSizeCode", method = RequestMethod.POST)
   BigDecimal queryMaxBasicPriceByPizzaSizeCode(@RequestBody String pizzaSizeCode);

   @RequestMapping(value = "/product/queryCategoriesCodeByProductCode", method = RequestMethod.POST)
   String queryCategoriesCodeByProductCode2(@RequestBody String productCode);
}

@Configurable
public class DisableHystrixConfiguration {

/*@Bean
@Scope ("prototype")
public Feign.Builder feignBuilder() {
return Feign.builder();

}*/

   @Bean
public Feign.Builder feignHystrixBuilder() {
return HystrixFeign.builder().setterFactory(new SetterFactory() {
public HystrixCommand.Setter create(Target<?> target, Method method) {
   String groupKey = target.name();
   //@FeignClient(name = "xxx-im"
   System.out.println(groupKey);
   String commandKey = method.getName();
   System.out.println("commandKey=="+commandKey);

   //打印,为每一个方法生成一个对象，此时groupKey，commandKey没用，可以设置超时时间
   /**
   * xxx-im2
                   commandKey==queryCategoriesCodeByProductCode2
                   xxx-im2
                   commandKey==queryCategoriesCodeByProductCode
                   xxx-im2
                   commandKey==queryMaxBasicPriceByPizzaSizeCode
   */
   int time = 6000;
   if("queryCategoriesCodeByProductCode2".equals(commandKey)) {
       time = 4000;
   }
return HystrixCommand.Setter
.withGroupKey(HystrixCommandGroupKey.Factory.asKey(groupKey))// 控制 RemoteProductService 下,所有方法的Hystrix Configuration
.andCommandKey(HystrixCommandKey.Factory.asKey(commandKey))
.andCommandPropertiesDefaults(
HystrixCommandProperties.Setter().withExecutionTimeoutInMilliseconds(time) // 超时配置
);
}
});
}

}

2.配置文件形式（配置文件只能精确到方法级别配置）
feign.hystrix.enabled=true
#hystrix.command.commandKey.execution.isolation.thread.timeoutInMilliseconds=300000
hystrix.command.IProductService\#queryCategoriesCodeByProductCode(String).execution.isolation.thread.timeoutInMilliseconds=300000

hystrix-core版本：1.5.6

feign-core版本：9.3.1
