【问题描述】:
这是我的第一个 spring-boot 项目,我对 tomcat 有问题。服务器不想启动。项目中没有用到玻璃鱼,我越是被这个消息惊到了。该项目是在 Maven 中创建的。 我已经为这个问题坐了好几个小时,但我找不到问题所在。有人可以帮助我吗?

【问题讨论】:
-
Glassfish 罐子是泽西岛的一部分。您似乎为您的应用程序使用了三种不同的 Web 框架,Jersey (spring-boot-starter-jersey)、Spring MVC (spring-boot-starter-web) 和 Spring WebFlux (spring-boot-starter-webflux)。典型的应用程序只会使用其中之一。有些人可能会使用 Jersey 和 Spring MVC。您不能将 WebFlux 与其他组合,因为您不能将响应式 (WebFlux) 与阻塞式 (Spring MVC 和 Jersey) 混合使用。

Andy Wilkinson - 你说得对,我删除了 (spring-boot-starter-webflux) 但问题一直都是一样的。
