我的春季启动应用程序初始化时，我需要使用带有@Component @FeignClient（name =“ xxx”）的bean注入，但是它总是会引发如下异常：
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feignClient代码：
@Component
@FeignClient(name = "domain-account")
public interface IDomainService {
@RequestMapping(value = "/userInfos", method = RequestMethod.GET)
public String getUserInfos(@QueryMap Map<String, Object> condition);
}
ApplicationListenner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();
}
}
最佳答案
对于我来说，还不清楚您要如何使用GlobalInit进行操作，但是在Spring Boot中设计Feign客户端的“标准”方法如下：
@SpringBootApplication
@EnableFeignClients
@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
@EnableCaching
public class MyHelloWorldApplication {
public static void main(String[] args) {
SpringApplication.run(MyHelloWorldApplication.class, args);
}
}
@Component
public class HelloWorldServiceImpl implements HelloWorldService {
@Autowired
private IDomainService iDomainService ;
public void myMethod() {
String userinfo = iDomainService.getUserInfos(...);
}
}
希望这会有所帮助。
祝一切顺利，
