Add context path to Spring Boot application

I am trying to set a Spring Boot applications context root programmatically. The reason for the context root is we want the app to be accessed from localhost:port/{app_name} and have all the controller paths append to it.

Here is the application configuration file for the web-app.

@Configuration
public class ApplicationConfiguration {
Logger logger = LoggerFactory.getLogger(ApplicationConfiguration.class);
@Value("${mainstay.web.port:12378}")
private String port;
@Value("${mainstay.web.context:/mainstay}")
private String context;
private Set<ErrorPage> pageHandlers;
@PostConstruct
private void init(){
pageHandlers = new HashSet<ErrorPage>();
pageHandlers.add(new ErrorPage(HttpStatus.NOT_FOUND,"/notfound.html"));
pageHandlers.add(new ErrorPage(HttpStatus.FORBIDDEN,"/forbidden.html"));
}
@Bean
public EmbeddedServletContainerFactory servletContainer(){
TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
logger.info("Setting custom configuration for Mainstay:");
logger.info("Setting port to {}",port);
logger.info("Setting context to {}",context);
factory.setPort(Integer.valueOf(port));
factory.setContextPath(context);
factory.setErrorPages(pageHandlers);
return factory;
}
public String getPort() {
return port;
}
public void setPort(String port) {
this.port = port;
}
}

Here is the index controller for the main page.

@Controller
public class IndexController {
Logger logger = LoggerFactory.getLogger(IndexController.class);
@RequestMapping("/")
public String index(Model model){
logger.info("Setting index page title to Mainstay - Web");
model.addAttribute("title","Mainstay - Web");
return "index";
}
}

The new root of the application should be at localhost:12378/mainstay, but it is still located at localhost:12378.

What am I missing that is causing Spring Boot to not append the context root before the request mapping?
