@RequestMapping("/greeting") not being mapped about gs-spring-boot

[gregturn]

Looking at your example, your usage of @Controller makes this a view-based controller, expecting a template named greeting.html.

Why are you extending SpringBootServletInitializer? That's only needed for certain older configurations.

No :-( I'm trying to do the same thing in the greeting example in my project. The repo is private so I don't know how much you can help. The logs look like it's working but when I try to this the service at http://localhost:8080/myservice/greeting or http://localhost:8080/greeting I get 404

I have the greeting.html in src/main/resources/templates/greeting.html.

I was reading something and added SpringBootServletInitializer. I'm noticing without it, it doesn't say spring is detected, like I don't see the sping logo in the console. Also noticed with or without SpringBootServletInitializer I can run it as a java app and hit /greeting, but not the non spring servlets. When I run it as Tomcat I can't hit /greeting but can hit my non sping servlets.

First of all, are you trying to build a WAR file? If not, then you can drop the customizations to spring-boot-maven-plugin, the maven-compiler-plugin, and replace spring-boot-starter-tomcat with spring-boot-starter-web. No need for the Java servlet API JAR either. By default, this version of Boot runs on servlet 3.1, which is modern day Tomcat.

Second of all, what I'm seeing veers way off course of what this is aimed at, so solving it without a proper code base to work against isn't really well suited in a ticket tracker used to manage changes to this guide. I wonder if you would be better served posting your use case on stackoverflow, because I feel as if something in missing the problem declaration.
