tomcat - 在AWS Elastic Beanstalk上启动期间Grails 4 App停顿

Question

我有一个Grails 4.0.1应用程序，可以在本地正常运行。我可以使用java -jar...运行WAR文件，但是我尝试将其部署到运行Java 8和Tomcat 8的AWS Elastic Beanstalk中，并且它在启动过程中停顿了，根本没有任何错误消息。

Answer 1

原来我错过了两件事:

我需要标记提供的Spring Boot Starter Tomcat Artifact ，因此它不会与外部Tomcat容器冲突。

dependencies {
    ...
    provided "org.springframework.boot:spring-boot-starter-tomcat"
    ...
}

我还需要增加容器的大小。我试图在t3.nano上运行，然后撞到了t3.micro。
