RequestMapping returns 404 error

Question

Yep, I know - there are tones of such questions. I tryed to scan all of them, but the didn't help me. Here is my code:

dispatcher servlet

<context:component-scan base-package="com.package.controller" />
<mvc:annotation-driven />
<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/"
      p:suffix=".jsp" />

web.xml

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

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

Controller:

@Controller
public class HomeController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public ModelAndView hello() {
    return new ModelAndView("index");
   }
}

Files location

HomeController is located in com.package.controller package.

index.jsp is located in WEB-INF/jsp/ package.

URL I'm trying to access is: localhost:8080/hello.do

What am I doing wrong? Thanks for help!

MDaniyal, Sorry, skiped your question. File name is *dispatcher-servlet.xml* — Иван Николайчук, Apr 08 '16 at 04:21

Tried to give @RequestMapping("*") on HomeController. localhost:8080/hello.do is still invalid. Thanks for help, anyway :) – Иван Николайчук Apr 08 '16 at 04:15
didn't help either – Иван Николайчук Apr 08 '16 at 04:17
is the name of your dispatcher file is `dispatcher-servlet.xml` ? – MDaniyal Apr 08 '16 at 04:17
ok then try `value = "hello"` instead of `value = "/hello"` on your method with `@RequestMapping("*")` on your class – MDaniyal Apr 08 '16 at 04:22
Ok, now I have `@RequestMapping("*")` on my controller class, `@RequestMapping(value = "hello")` on my hello method, and (didn't change it) dispatcher, looking for **.do* pattern. But URL http://localhost:8080/hello.do is still invalid. – Иван Николайчук Apr 08 '16 at 04:29
Your code is working like a charm the only difference in my case is the bean defination: – MDaniyal Apr 08 '16 at 04:37
Thats really strange. Maybe some bug in Idea? What IDE are you using? – Иван Николайчук Apr 08 '16 at 04:42
No this is not possible, I am using IntelliJ Idea 14.1.4 – MDaniyal Apr 08 '16 at 04:43
Can you send your project to me? – MDaniyal Apr 08 '16 at 04:43
Sure, thanks a lot for your help. Here is a link: https://github.com/IvanNikolaychuk/tmp – Иван Николайчук Apr 08 '16 at 04:50
I have edited the answer kindly check now @ИванНиколайчук – MDaniyal Apr 08 '16 at 05:24
thats really strange. I followed this structure and it still doesn't work. I recorded a video, showing all my steps, they look valid for me. Can you please take a look at it? Here is a link: https://yadi.sk/i/FPqqwvYLqq7WM (you'd better download it before watchin - the quality will be good then) – Иван Николайчук Apr 08 '16 at 08:01
Hey, I got it! The problem is: in my Intellij configs, servlet-dipatcher was mapped as "Spring Application context" first, and only then as "MVC dispatcher servlet". Seems like this file was treeted as "App context" only. When I swaped this order, everything went fine. Thanks a lot for your help! – Иван Николайчук Apr 08 '16 at 11:05
Sorry I didn't get time to see your video. That I was thinking but forget to told you that you can check this by going to `View --> Tool Windows --> Spring` there you can check all Beans and MVC components. – MDaniyal Apr 08 '16 at 12:48

Your url is not correct. Try with localhost:8080/"yourapplicationName"/hello.do. For example in my case if my application war file is abc.war then the url would be localhost:8080/abc/hello.do
