spring-cloud霍克斯顿.SR3+spring-cloud-alibaba2.2.0.REL

组件名称 Nacos Discovery, Sentinel,openfeign

错误描述 integration errors

To Reproduce Steps to reproduce the behavior:

1.com.alibaba.cloud spring-cloud-alibaba-dependencies 2.2.0.RELEASE pom import

org.springframework.cloud spring-cloud-dependencies Hoxton.SR3 pom import

com.alibaba.cloud spring-cloud-starter-alibaba-sentinel

org.springframework.cloud spring-cloud-starter-openfeign

org.springframework.boot spring-boot-starter-actuator

org.springframework.boot spring-boot-starter-web

com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery

org.projectlombok lombok true

create a interface

@FeignClient(value = "nacos-payment-provider", fallback = PaymentFeignServiceImpl.class) public interface PaymentFeignService { @GetMapping("paymentSQL/{id}") CommonResult paymentSQL(@PathVariable("id") Integer id); } 3. create the interface impl public class PaymentFeignServiceImpl implements PaymentFeignService { @OverRide public CommonResult paymentSQL(Integer id) { return new CommonResult(444, "服务降级返回", new Payment(id, "error")); } } 4. run 5. error

6.if update spring cloud Hoxton version from Hoxton.SR3 to Hoxton.SR1 ，run good
