Spring MVC WARNING: No mapping found for HTTP request with URI 404

Question

I am new with spring and I should do the project without Boot. Maybe you will see what I am doing wrong.

I should get a note on console "working". But instead of I just getting an error when my URL is on: http://localhost:8081/UserService/working?.

I think their problem with servlet mapping. @RequestMapping cant be seen.

web.xml

@EnableWebMvc
@Controller
public class NewUserController {
 
 @RequestMapping("/working", method = RequestMethod.GET)
 public void working() {
  System.out.println("Working");
 }

}

<input type="text">Email<br>
<input type="text">Name<br>
<input type="text">Password<br><br>
<button>Submit</button>
</form>
</body>
</html>

At the end I am getting:

WARNING: No mapping found for HTTP request with URI [/UserService/working] in DispatcherServlet with name 'alwaysUseFullPath'

my bad for the above comment, this should be fine https://stackoverflow.com/a/4140659/3892213 — best wishes, Feb 14 '18 at 02:32

You can map more specific URL pattern like *.html, .do, /pages/, /app/*, etc. For example in your code :

<url-pattern>*.do</url-pattern> or <url-pattern>*.html</url-pattern>

<servlet>
  <servlet-name>alwaysUseFullPath</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>/WEB-INF/servlet-context.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
 </servlet>

 <servlet-mapping>
  <servlet-name>alwaysUseFullPath</servlet-name>
  <url-pattern>*.do</url-pattern>
 </servlet-mapping>

In Spring controller the method request mapping patten looks like this :

/working.do or /working.html

@EnableWebMvc
@Controller
public class NewUserController {
 
 @RequestMapping("/working.do", method = RequestMethod.GET)
 public void working() {
  System.out.println("Working");
 }

}

This is usually we do to hide actually mapping from end user.
