No mapping found for GET /api/keyservice/key - spring

Question

I'm creating a spring-rest-app.
This is my dispatcher config (I also have a root config that has DataSource bean)
#Configuration
#ComponentScan(basePackages= {"config", "cache", "dao", "entity", "exception", "rest", "service"})
#EnableWebMvc
public class DispatcherConfiguration {
#Bean
public KeyCache keyCache() {
return new KeyCacheImpl();
}
}
This is my webapp initializer
public class TinyURLKeyServiceInitializor implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext appcontext = new AnnotationConfigWebApplicationContext();
appcontext.register(ConfigurationClass.class);
servletContext.addListener(new ContextLoaderListener(appcontext));
AnnotationConfigWebApplicationContext dispatchercontext = new AnnotationConfigWebApplicationContext();
dispatchercontext.register(DispatcherConfiguration.class);
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(dispatchercontext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
This is the controller
#Controller
#RequestMapping("/api/keyservice")
public class KeyServiceController {
#Autowired
private KeyService keyService;
#GetMapping(value="/key", produces="application/json")
#ResponseBody
public String getKey() {
return keyService.getKey();
}
}
When I startup the Web app and Send - GET http://localhost:7080/api/keyservice/key
I get the following in DEBUG LOG
[INFO] Completed initialization in 1006 ms
May 17, 2020 11:56:10 PM org.apache.coyote.AbstractProtocol start
INFO: Starting ProtocolHandler ["http-bio-7080"]
[DEBUG] GET "/api/keyservice/key", parameters={}
[WARNING] No mapping for GET /api/keyservice/key
[DEBUG] Completed 404 NOT_FOUND
I've put #EnableMvc for registring MappingHandlers. But still they are not able to detect the mapping between endpoint and controller method.
I put a debug point in DispatcherServlet.getHandler and it returns null everytime. Has anyone ever faced similar problem?

Found the reason I was hitting -
http://localhost:7080/api/keyservice/key
My pom.xml had -
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>7080</port>
<path>/api/keyservice</path>
</configuration>
</plugin>
My Controller
#Controller
#RequestMapping("/api/keyservice")
public class KeyServiceController {
#Autowired
private KeyService keyService;
#GetMapping(value="/key", produces="application/json")
#ResponseBody
public String getKey() {
Since context path = /api/keyservice (due to setting in pom.xml), spring was trying to find a mapping for /key. Cleary there is no mapping for /key in my controller.
Removed the controller RequestMapping. And it worked.
