How to deploy swagger generated spring code (Tomcat) - spring

Question

I used the example given by SwaggerCodeGen to create a Server via SpringBoot.
I build the project with maven and run it local. Everythings works fine.
Now I want to deploy this project on a tomcat (version 7).
So I changed the packing from jar to war
<packaging>war</packaging>
and moved the *.war file to tomcat\webapps folder
I tried to run
localhost:8080/app
which return an 404
same with
localhost:8080/app/swagger-ui.html
localhost:8080/v1/app/
localhost:8080/v1/app/api-docs
Unfortunatly, I have got no experience with tomcat.
The Project doesn't contain a web.xml. Is it necessary?
Do I need to create a Servlet?
Any help would be appreciated.

In your POM you need:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
and
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.5.9</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
Your SpringBoot Application should also look like this:
public class SpringBootServiceApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SpringBootServiceApplication .class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootServiceApplication .class);
}
}
