развернуть проект dubbo для Springboot на внешнем tomcat, выдать исключение TimeoutException

0 голосов
/ 04 марта 2020

Я развертываю войну производителей и потребителей на внешнем Tomcat, когда потребитель вызывает удаленный метод производителя, потребитель выбрасывает TimeoutException. Но когда я использую встроенный в Springboot tomcat (spring-boot-starter-tomcat), RP C все в порядке, не исключение. Я пытался увеличить атрибут timeout на dubbo:service, но это бесполезно.

Springboot: 2.2.4.RELEASE Dubbo: 2.6.6 Tomcat : 9.0.13 zookeeper: 3.5.7

конфигурация на стороне производителя xml :

<!-- service implementation, as same as regular local bean -->
