春季靴子不要在tomcat9上初始化

Question

我将头发拉出，因为我只是无法将Spring Boot应用程序部署到外部Tomcat9。我做了一个REST API，并且正在尝试在tomcat上部署，但是即使我尝试这样做（顺便说一句，这很好），或者如果我将.war复制到WebApps文件夹，我也无法请参阅catalina.bat的控制台日志上的弹簧字母。我正在尝试在Localhost：8080/Scim（这是我的.war -scim.war的名称），但我遇到了404错误。我期望看到春季的白色空白页错误，但没有出现。当我比较在 javatpoint 我看不到pom.xml，xml，xml，或主要课程。我基本上用 mvn Clean install 命令打包了.war，但它不会带来任何错误，所以我想这是正确的。有人可以帮我吗？ Stackoverflow中的所有其他链接对我不起作用。 任何其他细节，请告诉我。

如您所见，似乎Spring仅在我用来比较的项目上开始。

Answer 1

您正在Java 8上运行tomcat：

Using JRE_HOME:        "C:\Program Files\Java\jre1.8.0_333"

您的应用程序配置为使用Java 11：

<java.version>11</java.version>

在Java 8上运行，Tomcat将无法读取使用Java 11的应用程序。不幸的是，Tomcat不会记录有关此内容的任何内容使问题难以诊断。

您应该能够通过在Java 11上运行Tomcat或更改应用程序使用Java 8来解决问题。
