Question

在外部TOMCAT中启动后，Spring Boot立即关闭。但是在Eclipse中，它运行良好，并且还嵌入了JAR。

我使用Tomcat 7和JAVA 8。我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

            </configuration>
        </plugin> 

    </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)

有人可以帮我吗？

很难从您提供的信息中说出来，但是对我来说，可疑的是您使用的是spring-boot-starter-web，这反过来又带来了tomcat启动器。

我看到这个模块的包装是WAR，因此它打算在外部Web容器中运行，但是另一方面，您说它在“嵌入JAR”中也可以正常运行。所以有点混乱。

我从未将Spring Boot应用程序作为WAR文件部署，但我相信您可以转到Start.spring.io并生成一个示例应用程序，将其自身打包到WAR中。默认情况下不显示此选项，因此您必须单击“切换到完整版本”链接

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