Spring 5 MVC not finding mapping to controller returning JSON

I'm new to Spring 5, and I've been studying all the different sites about Spring 5 MVC, learning as much as possible, but still can't get a response to "http://localhost/[webcontext]/secure/json/organizations". I end up with this: [o.s.web.servlet.DispatcherServlet] Completed 404 NOT_FOUND. I can tell that the class is loaded and autowiring complete as I had to fix those problems.
Below is my code. What am I missing or doing wrong?

EnrollmentRestController.java

package c.i.i.w.e.controllers;

@RestController
public class EnrollmentRestController extends AbstractIfactoryController
{
  @GetMapping(path = "/secure/json/organizations", produces = MediaType.APPLICATION_JSON_VALUE)
  public QueryResults<OrganizationQueryResult> execute() throws ApplicationException
  {
    return super.getEnrollmentService().findOrganizations();
  }
}

ApplicationInitializer.java:

package c.i.i.w.e.config;

@Configuration
@EntityScan("c.i.i.w.e")
@ComponentScan(basePackages = {"c.i.i.w.e"})
public class ApplicationInitializer implements WebApplicationInitializer
{
  static final String PU_NAME                 = "i";
  static final String SERVLET_MAPPING         = "/";
  static final String SERVLET_NAME            = "spring";

  @Bean(name = "entityManagerFactory")
  public LocalEntityManagerFactoryBean entityManagerFactory()
  {
    LocalEntityManagerFactoryBean entityManagerFactory = new LocalEntityManagerFactoryBean();

    entityManagerFactory.setPersistenceUnitName(PU_NAME);

    return entityManagerFactory;
  }

  private void newAppServlet(
    ServletContext servletContext,
    AnnotationConfigWebApplicationContext appContext)
  {
    DispatcherServlet dispatcherServlet = new DispatcherServlet(appContext);
    ServletRegistration.Dynamic appServlet = servletContext.addServlet(SERVLET_NAME,
      dispatcherServlet);

    appServlet.setLoadOnStartup(1);
    appServlet.addMapping(SERVLET_MAPPING);
  }

  @Override
  public void onStartup(
    ServletContext servletContext) throws ServletException
  {
    AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();

    appContext.register(DispatcherConfig.class);
    appContext.setServletContext(servletContext);
    appContext.refresh();

    servletContext.addListener(new ContextLoaderListener(appContext));

    newAppServlet(servletContext, appContext);
  }
}

DispatcherConfig.java

package c.i.i.w.e.config;

@Configuration
@EnableWebMvc
public class DispatcherConfig implements WebMvcConfigurer
{
  @Override
  public void configureDefaultServletHandling(
    DefaultServletHandlerConfigurer configurer)
  {
    configurer.enable();
  }

  @Override
  public void configureContentNegotiation(
    ContentNegotiationConfigurer configurer)
  {
    configurer.favorPathExtension(false).favorParameter(true);
  }

  @Override
  public void configurePathMatch(
    PathMatchConfigurer configurer)
  {
    configurer.setUseSuffixPatternMatch(false);
  }

  @Override
  public void addResourceHandlers(
    ResourceHandlerRegistry registry)
  {
    registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(31556926);
  }

  @Bean
  public ViewResolver internalResourceViewResolver()
  {
    InternalResourceViewResolver bean = new InternalResourceViewResolver();
    
    bean.setViewClass(JstlView.class);
    bean.setSuffix(".jsp");
    
    return bean;
  }
}

Here's the last few lines from the log file

I'm not sure which changed fixed this, but here's the end results that now work.

dispatcher = servletContext.addServlet(SERVLET_NAME, dispatcherServlet);

}
@Override

What's your local server's port? Don't you have a port number such as http://localhost:portNumber/secure/json/organizations You can try 8080 or other defaults depending on your local server.
