</web-app>

enter image description here

and my dispatcherservlet-servlet.xml is 

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <mvc:resources mapping="/style/**" location="/style/"/>
<mvc:default-servlet-handler/>

<context:annotation-config/> 
   <context:component-scan base-package="com"/>
</beans>

finally my controller

    package com;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class addition {

    @RequestMapping("/add")
 void add() {
     System.out.println("im addint");
 }
}

my index.jsp as welcome file

 <html>
<body>
<h2>Hello World!</h2>
<form action="add">
<input type="text" name="first number">first number<br>
<input type="text" name="second number">second number<br>
<input type="submit" name="add two numbers"><br>

</form>
</body>
</html>

when I run I can submit and hit the URL for add method but im getting WARNING: No mapping found for HTTP request with URI [/mvc/add] in DispatcherServlet with name 'dispatcherservlet'

Solution

  • You are missing <mvc:annotation-driven /> on dispatcherservlet-servlet.xml, which enables @Controller annotation.
