错误信息

在OpenFeign整合Sentinel的时候出现循环依赖的报错

Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException:Error creating bean with name 'top.mowang.cloud.service.PaymentService': Requested bean is currently in creation: Is there an unresolvable circular reference?

环境信息

Spring Cloud和Spring Cloud Alibaba版本信息：

<!--spring cloud Hoxton.SR12-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>Hoxton.SR12</version><type>pom</type><scope>import</scope>
</dependency>
<!--spring cloud alibaba 2.1.0.RELEASE-->
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>2.2.1.RELEASE</version><type>pom</type><scope>import</scope>
</dependency>

我是在当前OpenFeign能成功整合Hystrix的前提下进行和Sentinel整合

在开启Sentinel对Feign的支持的配置后在启动时就出现了循环依赖的问题

开启Sentinel对Feign的支持：

feign:sentinel:enabled: true

PaymentService类：

@FeignClient(value = "nacos-payment-provider",fallback = PaymentFallbackService.class)
public interface PaymentService {@GetMapping(value = "/paymentSQL/{id}")public CommonResult<Payment> paymentSQL(@PathVariable("id") Long id);
}

PaymentService在注入到controller出现了循环依赖

问题原因和目前的解决方案

问题出在Spring Cloud和Spring Cloud Alibaba的版本上，具体就是Sentinel和OpenFeign版本兼容问题，目前的解决方案就是切换为兼容的版本，等待官方修复，在将spring cloud版本为Hoxton.SR3，spring cloud alibaba版本为2.1.0.RELEASE后正常启动，问题解决

<!--spring cloud Hoxton.SR3-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>Hoxton.SR3</version><type>pom</type><scope>import</scope>
</dependency>
<!--spring cloud alibaba 2.1.0.RELEASE-->
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>2.2.1.RELEASE</version><type>pom</type><scope>import</scope>
</dependency>
