ZKspringboot deploy to tomcat - no working examples

I think it was mostly issues in my project after working on it for a while. I'll post some thoughts so if anyone else runs into similar, they might find something helpful.

1) I ran into issues with the POM following what is in GitHub (zkspringboot-minimal-war). Errors similar to (Could not initialize class org.apache.maven.plugin.war.util.WebappStructureSerializer) For me the only way to solve these issues were by adding the following in the build - plugins section of the pom (after the org.springframework.boot plugin):

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

2) My spring starter had already created a seperate Servlet Initializer class in the same package as my SpringBootApplication class. If you look at the zkspringboot-minimal-war it has the SpringBootApplication class extend SpringBootServletInitializer and adds in

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

So you need to get rid of the extra Initializer class if your spring starter created that.

3) I had to ignore the different startup messages displayed in Spring startup when using spring-boot: run - versus deployed on Tomcat. When deployed on Tomcat I don't see messages about ZK Servlet initializing. However it still is working

4) Difference in running on Tomcat container in Eclipse - versus packaged war deployed on Tomcat. When referencing the path in browser:

• Tomcat on Eclipse the spring project doesn't answer on the name of your project like some web apps will. It answers on the artifact name you have configured in pom. You can double check once you deploy by looking in your project's .settings folder for a file called org.eclipse.wst.common.component

you'll see something like

<property name="context-root" value="rps-controller"/>

• When deployed on tomcat as a war, it will of course follow the name of your war file in the path.
