Spring Boot Application 在外部 TOMCAT 中启动后立即关闭

Question

Spring boot 在外部 TOMCAT 中启动后立即关闭。但在 Eclipse 中，它运行良好，并且 JAR 也可以嵌入。

我使用 Tomcat 7 和 JAVA 8。 我阅读了很多不存在的网站和文档。

我的 Eclipse POM 是：

http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

    </plugins>
</build>

Tomcat 输出日志的最后几行是：

2018-06-29 10:27:37.874  INFO 640 --- [ost-startStop-3] com.suez.demo.SuezApplication            : Started SuezApplication in 29.104 seconds (JVM running for 91.714)

有人可以帮帮我吗？

根据您提供的信息很难说，但在我看来可疑的是您使用的是 spring-boot-starter-web ，它反过来会传递 tomcat starter。

我看到这个模块的包装是WAR，所以它打算在外部Web容器中运行，但另一方面，你说它在“JAR with embed too”中运行良好。 所以有点混乱。

我从来没有自己将 Spring Boot 应用程序部署为 WAR 文件，但我相信您可以转到 Start.spring.io 并生成一个将自身打包到 WAR 中的示例应用程序。默认情况下不显示此选项，因此您必须单击“切换到完整版”链接
