Change your controller to GET
#RequestMapping(value = "/hello",method = RequestMethod.GET)
public ModelAndView mymethod(){
return new ModelAndView("hello","msg","Hello First Spring");
}
Also change your web.xml
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

I checked out nearly every relevant article on stackoverflow already, but I just cant fix my problem.

Your configuration looks ok. However you are requesting for the /CloudService/ url which is not mapped to any controller handler method. Your Controller has a handler for /CloudService/hello instead. You can either include a handler for / or if both / and /hello should be handled by the same method you can do it this way
#Controller
#RequestMapping({"/hello" , "/"})
public class HelloController{
#RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
N.B Your application has one application context HelloWeb-servlet.xml therefor you don`t need a ContextLoaderListener configuration to create a parent context.However as soon as you have service beans which must be separated into a different context you need to configure it

I am sure this should work for you as well.

The contents of the file index.jsp is very long and I don't write it here.
I think you are missing below entries in your springConfig-Servlet.xml file.
<mvc:default-servlet-handler />
<mvc:annotation-driven />
