解决方案：

• 若不需要对 Feign 链路追踪，可以通过 Spring Cloud Sleuth 提供的属性 spring.sleuth.feign.enabled=false 来使其关闭。

• 若需要同时使用，在启动类加入排除@SpringBootApplication(exclude = {SeataFeignClientAutoConfiguration.class})
  再配置 Feign 的拦截器

@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);
        }
    }
}
