Spring Boot Deployed in Tomcat gives 404 but works Stand-alone

Question

I have been testing Spring Boot with embedded Tomcat for about a month now to build a REST API. Everything was working fine. We now want to deploy the API in a separate deve

Answer 1

check java -version means the if you complied war in java 8 and tomcat is running on java 7 then it doesn't work.

Answer 2

When running an application the path to call consists of a couple of parts.

The first is the base URL on which the application is deployed, in your case that is /sophia.

The second is the servlet mapping of the DispatcherServlet in your case that is /sohpia/*.

The third is the mapping of the controller inside the DispatcherServlet, in your example that is /users.

All those things combined create the URL /sophia/sophia/users.

The difference between the deployment as a WAR is that you included a separate URL to deploy on, when running as a jar it, by default, is deployed to / (the root).

You could fix it by putting /sophia as the server.context-path in the application.properties and map the DispatcherServlet to /* or /. That will in both situations give you the URL you want (and expected).

Answer 3

Have you tried extending the SpringBootServletInitializer and overriding the configure method? As stated here

The entry point for jar file is different [Main Class] when compared to running your app as war file inside a container.

Hope this helps.
