在外部TOMCAT中啟動后，Spring Boot Application立即關閉

Question

在外部TOMCAT中啟動后，Spring Boot立即關閉。 但是在Eclipse中，它運行良好，並且還嵌入了JAR。

我使用Tomcat 7和JAVA8。我閱讀了許多不存在的Web和文檔。

我的Eclipse POM是：

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

</build>

Tomcat輸出日志的最后幾行是：

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)

有人能幫助我嗎？

Answer 1

很難說出您提供的信息，但是對我來說，可疑的是您使用的是spring-boot-starter-web，這反過來又帶來了tomcat啟動器。

我看到該模塊的包裝是WAR，因此它打算在外部Web容器中運行，但是另一方面，您說它在“嵌入JAR”中也可以正常運行。 所以這有點令人困惑。

我從來沒有一個人將Spring Boot應用程序部署為WAR文件，但是我相信您可以轉到Start.spring.io並生成一個示例應用程序，該應用程序會將其自身打包到WAR中。 默認情況下不顯示此選項，因此您必須單擊“切換到完整版本”鏈接
