java当spring启动应用程序初始化时,如何获取@FeignClient bean
当我的spring boot应用程序初始化时,我需要使用带有@Component@FeignClient(name=“xxx”)的bean注入,但它总是引发如下异常:
20180706 10:18:40,043 WARN [main]
[org.springframework.context.annotation.AnnotationConfigApplicationContext]
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'feignContract' defined in org.springframework.cloud.netflix.feign.FeignClientsConfiguration: Unsatisfied dependency expressed through method 'feignContract' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'feignConversionService' defined in org.springframework.cloud.netflix.feign.FeignClientsConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.format.support.FormattingConversionService]: Factory method 'feignConversionService' threw exception; nested exception is java.lang.StackOverflowError
我的假客户代码:
@Component
@FeignClient(name = "domain-account")
public interface IDomainService {
@RequestMapping(value = "/userInfos", method = RequestMethod.GET)
public String getUserInfos(@QueryMap Map<String, Object> condition);
}
应用程序侦听器代码:
public class GlobalInit implements ApplicationListener<ContextRefreshedEvent> {
@Override
public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
System.out.println("======== GlobalInit ========");
IDomainService domainService = contextRefreshedEvent.getApplicationContext().getBean(IDomainService.class);
System.out.println("*********************" + domainService);
GlobalInitManager.getInstance().doInit();
}
}

我不完全清楚你想用GlobalInit做什么,但在Spring Boot中设计你的外设客户端的“标准”方法是:
