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-->

<groupId>org.springframework.cloud</groupId>
