org.springframework.web.servlet.DispatcherServlet noHandlerFound : Spring MVC
Question
I am new to spring MVC. I tried creating small hello world app but it is not running as expected. I am always getting error org.springframework.web.servlet.DispatcherServlet noHandlerFound WARNING: No mapping found for HTTP request with URI [/FitnessTracker/greeting.html] in DispatcherServlet with name 'fitTrackerServlet'
I know this error is very common and there are lots of links available on the google but none of them worked for me. Any help would be appreciated.
Here is the code snippet
HelloController.java
@Controller
public class HelloController {
@RequestMapping(value = "/greeting")
public String sayHello(Model model) {
model.addAttribute("greeting","Hello World!!!!");
return "hello";
}}

The URL /greeting does not have any .html at the end, so the servlet will not going to use the DispatcherServlet, because *.html pattern does not match the /greeting, and this will result in 404.
Change your web.xml such:
<servlet-mapping>
<servlet-name>fitTrackerServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
