I have a Spring Boot application that uses Thymeleaf for email templating. My application is not a web application though.
However, when including the spring boot starter thymeleaf dependency:
compile('org.springframework.boot:spring-boot-starter-thymeleaf')
Spring MVC is transitively included and eventually Servlet.class in my class path signaling that my application is a web application... which then has the undesirable result of running my application in the Tomcat servlet container (by default on port 8080).
How can I use the features of Spring Boot Thymeleaf (such as configuring in a props file ala https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html) without my application running as a web application?
Setting the following property as follows prevents the Spring Boot application from running as web application:
spring.main.web-environment=false

I have created a spring boot application with a few endpoints and want to make that endpoint to the existing servlet application without deploying it separately. So I want to create a jar from the spring boot app and use that jar in the servlet project. How can this be done? Any suggestion would be really helpful.
The application runs fine on spring boot embedded tomcat 8.5.28 (gradle bootRun) but when I create the war and put the same in stand alone tomcat server (8.5.28) the application always throws 404 for any of the routes configured.

Spring Boot 2.0 does not currently support WAR deployment for WebFlux applications.
See the Spring Boot issue you created: https://github.com/spring-projects/spring-boot/issues/12455
I just created a new application using Spring boot 2 M7 and I'm using spring-webflux.
I built the application as an autoexecutable war that I can start in dev with java -jar app.war and also on a standalone tomcat server for UAT purpose.
In the web reactive reference doc, I read
To deploy as a WAR to a Servlet 3.1+ container, wrap HttpHandler with ServletHttpHandlerAdapter and register that as a Servlet. This can be automated through the use of AbstractReactiveWebInitializer.
Baeldung site also wrote about it and they describe a procedure to register a servlet that wrap the router for a standalone environment.
Using Spring boot tomcat starter, I didn't need to do anything : no code about booting the server necessary ; the app starts using the embedded server. In debug I saw NIO access so all seems fine.
I didn't try yet but what will happen on a standalone tomcat using Spring boot tomcat starter and webflux starter ? Is spring boot take care of everything (embbeded and standalone tomcat) ? how does it work ?
I would like to expose a Spring MVC controller in an application that will NOT be deployed in a web container like Tomcat. Is this possible? If so, can you please provide an example.
Spring boot has embedded servlet containers. This enables you to launch apps by executing a jar, instead of deployment to servlet container
I am using spring-boot to develop webservices, but I don't want to use WsConfigurerAdapter to define a WSDL and all, because I want to deploy my war into WAS7 and it does not support Servlet 3.0. So how would I add a web.xml configuration into my application.
Spring Boot doesn't support Servlet 2.5 out of the box, however you can use Spring Boot Legacy to get things working. Take a look at the Google App Engine sample application for an example of how to use Spring Boot Legacy and web.xml.
You may also be interested in this Spring Boot issue which is proposing to make Spring Boot Legacy an official part of Spring Boot.
