thank you for your attention in reading my problem;

I'm trying to deploy a spring boot application but when I put it in the tomcat webapps folder it doesn't load my application, does anyone know what could be happening?

I already tried to run several versions of java changing the system variables, I used several versions of tomcat but none unzip the application

I'm using java version 17 and version apache-tomcat-9.0.71

I thought Spring Boot came with a pre-installed web server, so there is no need to use this method. Why don't you use the current method which supports auto deployment of your application?

An Spring Boot application is a ready to run jar file which contains tomcat/jetty and can be run with java -jar <your app>.jar. When you want to run an application in tomcat you should build a .war file.

======================================

As found here: https://stackoverflow.com/a/27905557/2144466

Did you follow this guide: https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto.traditional-deployment

and do you have a class which extends SpringBootServletInitializer andd overwrites the configure method: ` @SpringBootApplication public class MyApplication extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(MyApplication.class);
}

public static void main(String[] args) {
    SpringApplication.run(MyApplication.class, args);
}

`

  • the war file was created correctly, however when I add it to the webapps folder in tomcat it does not start with the server in the log – Paulo Inácio Feb 16 '23 at 23:15

Please follow below.

  • Rename your war file at location webapps from web-0.0.1-SNAPSHOT.war to web.war
  • restart tomcat.
  • open url (http://localhost:8080/web) in browser.

  • Or you can go with jar build of spring boot and run `java -jar web.jar --server.port=9000` in commad prompt or terminal and open (http://localhost:9000/web) – Learner Feb 16 '23 at 21:43
  • I did that and it returned " HTTP Status 404 - Not Found " – Paulo Inácio Feb 16 '23 at 23:21
  • the project is not uploading in the log, will it be some incompatibility between versions of java, tomcat and maven? – Paulo Inácio Feb 16 '23 at 23:21

I managed to solve the problem.

Apparently it was version incompatibility between spring, tomcat and java, by adjusting the system variables I can deploy both java 11 and java 17 applications.

Even though I managed to find a solution, I thank the friends above for dedicating their time to trying to solve my problem.
