java.lang.IllegalStateException：没有定义负载平衡的假装客户端。 您是否忘记包含 spring-cloud-starter-netflix-ribbon？

问题描述

我得到了例外：

FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-netflix-ribbon?
    at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:178)

    at com.hsbc.gbgcf.spartan.referencedatabase.UserRegistrationApplication.main(UserRegistrationApplication.java:57)

在执行我的项目时。 我的 pom.xml 包含

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
  </dependency>

我也在我的其他项目中使用 feign 客户端，没有任何额外的功能区依赖，这些都使用相同的 spring-boot 版本 2.0.8

我已经针对相同的问题引用了其他堆栈溢出链接，他们要求添加功能区的其他依赖项。 我尝试在我的 pom.xml 中添加相同的内容，但没有帮助。

FeignClient 接口是，

@FeignClient(value = "user-service", decode404 = true)
public interface UserFeignClient {

    @PostMapping("/do-something")
    void doSomething();
}

主类代码：

@Configuration
@EnableAspectJAutoProxy
@EnableFeignClients
@EnableDiscoveryClient
@SpringBootApplication(scanBasePackages = {"test.user"})
public class UserRegistrationApplication{
 public static void main(String[] args) {
        UserFeignClient userFeignClient = applicationContext.getBean(UserFeignClient.class);
        userFeignClient.doSomething();
        System.exit(SpringApplication.exit(applicationContext));
    }
}

我正在使用 Sprint Boot 版本 2.0.8。

使用spring-cloud-starter-loadbalancer依赖而不是spring-cloud-starter-netflix-ribbon 。

对我来说，问题是我没有在 feign 注释中包含 url

@FeignClient(name = "microservice-common", url = "${microservice-common.url}")
