Basic Spring MVC. HTTP 404 error. Tried all possible solutions

Question

I am having trouble executing basic spring mvc application. I have tried all possible solutions and finally wanted to get this resolved. I don't want to create a new workspace and do it again. I wanted to get this working. Here is my GitHub url for the project. I am landing on correct page (index.jsp).

I tried all these

1. <mvc:annotation-driven/>
2. <mvc:default-servlet-handler/>
3. Tweaked @RequestMapping from method to class and by changing it from (/welcome) to (value = "/welcome", method = {RequestMethod.GET,RequestMethod.POST})

Sometimes I see no-mapping-found-for-http-request-with-uri-in-dispatcherservlet-with-name error in console and sometimes its nothing.

I know there are many similar questions out there, I have gone through lot of questions and started this new thread. My problem is

Answer 1

Notice that, in your servlet mapping:

 <servlet-mapping>
    <url-pattern>/welcome.html</url-pattern>
 </servlet-mapping>

you have added url-pattern for welcome.html. But your controllers' request mapping is set as @RequestMapping("/welcome").

Either add url mapping for /welcome:
<servlet-mapping> <url-pattern>/welcome</url-pattern> </servlet-mapping>
so that in can get mapped to your controller.

Or change the request mapping of your controller to @RequestMapping("/welcome.html") so that the controller get mapped to welcome.html.

Answer 2

Check if this helps!. Change the servlet-mapping entry in Web.xml to what is below. You have to avoid putting lot of url-pattern in your web.xml

  <servlet-mapping>
        <servlet-name>basicspringmvc</servlet-name>
        <url-pattern>*htm</url-pattern>
    </servlet-mapping>

then try this http://localhost:8080/BasicSpringMVC1/welcome.htm
