zipkin和seata导致了openFeign不能远程调用服务

现象

number of retries on next server exceeded max 1 retries

解决方法

1. 在启动类中加忽略 @SpringBootApplication(exclude = {SeataFeignClientAutoConfiguration.class})

2. 加入全局拦截传递XID

   import feign.RequestInterceptor;
   import feign.RequestTemplate;
   import io.seata.core.context.RootContext;
   import io.seata.spring.annotation.GlobalTransactional;
   import org.apache.commons.lang3.StringUtils;
   import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
   import org.springframework.stereotype.Component;
   
   /**
    * 全局拦截传递XID
    */
   @Component
   @ConditionalOnClass({RequestInterceptor.class, GlobalTransactional.class})
   public class SetSeataInterceptor implements RequestInterceptor {
   
       @Override
       public void apply(RequestTemplate template) {
   
           String currentXid = RootContext.getXID();
           if (!StringUtils.isEmpty(currentXid)) {
               template.header(RootContext.KEY_XID, currentXid);
           }
       }
   }
   

结果
