Stack Overflow Asked by Gary Kephart on February 16, 2021
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.

Correct answer by Gary Kephart on February 16, 2021
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.
