Guided by Serving Web Content with Spring MVC, I'm creating a Spring Boot web application that I can run using both the embedded Tomcat instance as well as on a standalone Tomcat 8 server.
The application works as expected when executed as java -jar adminpage.war and I see the expected outcome when I visit http://localhost:8080/table. However, when I deploy to a Tomcat 8 server (by dropping adminpage.war into the webapps directory), I get a 404 error when I visit https://myserver/adminpage/table.
The catelina.log and localhost.log files contain nothing helpful on the Tomcat server.
Can anyone suggest where I've made a misconfiguration? I've not had the same problems in the past when deploying RESTful services with Spring Boot, but this is my first foray into a web application.
My application files:
src/main/java/com/.../Application.java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
src/main/java/com/.../MainController.java
@Controller
public class MainController {
@RequestMapping("/table")
public String greeting(Model model) {
model.addAttribute("name", "Fooballs");
return "table";
}
}
src/main/resources/templates/table.html
