Spring interprets urls /spring/createUser/ and /spring/createUser differently(atleast in POST methods that i just tested).

Change your @RequestMapping url to /spring/createUser.

Also mind that the url you call is /spring/createUser without a trailing slash("/").

Your method 

@RequestMapping(value = "/spring/createUser", method = RequestMethod.POST)

Hope this helps.

According to your servlet mapping only one url is allowed localhost:8080/context/spring/ that is not mapped with your controller.

When we defined a servlet-mapping, we are using SimpleUrlHandlerMapping. To understand servlet url mapping let define a servlet mapping : 

<servlet-mapping>
        <servlet-name>user</servlet-name>
        <url-pattern>/spring/*</url-pattern>
</servlet-mapping>

Now the handler will actually use the * part to find the controller. It will not search /spring/createUser, it will only search for /createUser to find a corresponding Controller.

@RequestMapping("/createUser")

In your case You need to either change your url to localhost:8080/spring/spring/createUser or remove prefix from Controller @RequestingMapping(/createUser).

since your servlet url mapping has already include /spring you don't need to include it in @RequestMapping.

try this:

@RequestMapping(value = "/createUser/", method = RequestMethod.POST)
