env:
案例1 :
客户端:springboot(1.5.12.RELEASE)+ spring-boot-admin-starter-client 1.5.7
admin:springboot(2.1.1.RELEASE)+ spring-boot-admin-starter-server 2.1.1
当我运行客户端并刷新管理应用程序时。错误是“对于异步状态为[MUST_DISPATCH]的请求,调用[asyncError()]无效”;
案例2 :
(2.1.1。发布)
客户端和服务器使用相同的版本,并且具有相同的错误。
详细错误如下:

SBA-UI正在使用一些长时间轮询,当浏览器关闭连接并且服务器尝试在其上写入一些数据时,会记录上述异常。所有这些都是很正常的。它不应该影响应用程序。 有关更多信息,请访问:https://github.com/spring-projects/spring-boot/issues/15057

实际上有一个简单的解决方案:只是不要使用Tomcat servlet容器,而是在反应式设置中运行管理服务器,例如:
@SpringBootApplication
@EnableAdminServer
public class AdminServer {
public static void main(String[] args) {
new SpringApplicationBuilder(AdminServer.class)
.web(WebApplicationType.REACTIVE)
.run(args);
}
}
这样,我不会出现任何错误。
