I'm pulling my hairs out because i just can't deploy a spring boot application to an external tomcat9. I did an rest API and i'm trying to deploy on tomcat but even if i try to do it trough the manager (which is working fine by the way) or if i copy the .war to the webapps folder, i can't see the Spring Letters on the console log of catalina.bat. I'm trying to reach at localhost:8080/scim (which is the name of my .war - scim.war) but i get the 404 error. I was expecting to see the white blank page error of Spring, but it don't appear. When i compare to this project that i found on this tutorial from JavaTPoint i cant see any difference on POM.xml, or main class. I packed the .war basically with the mvn clean install command, and it don't bring any error, so i guess that is right. Can someone help me? All the other links in stackoverflow don't work for me.
Any other details, just tell me.

As you can see, it seems that spring only starts on the project that i'm using to compare with.
CodePudding user response：
You are running Tomcat on Java 8:
Using JRE_HOME: "C:\Program Files\Java\jre1.8.0_333"
Your application is configured to use Java 11:
<java.version>11</java.version>
Running on Java 8, Tomcat will be unable to read the classes from your application that's using Java 11. It's unfortunate that Tomcat doesn't log anything about this which makes the problem hard to diagnose.
You should be able to fix the problem by running Tomcat on Java 11 or by changing your application to use Java 8.
