Issue with RequestMapping POST API?

I can't fiure out what I am doing wrong here. I am using the app "Postman" to send a request to a service. The parameter is a very simple POJO shown below. When I attempt to send the request I get a response: "The server refused this request because the request entity is in a format not supported by the requested resource for the requested method"

Class used for request:

 public class LoginAttempt {

        private String userName;
        private String password;
        public String getUserName() {
            return userName;
        }
        public void setUserName(String userName) {
            this.userName = userName;
        }
        public String getPassword() {
            return password;
        }
        public void setPassword(String password) {
            this.password = password;
        }
    }

API in controller:

@RequestMapping(value="/validate", method=RequestMethod.POST, produces="application/json") 
public boolean validateUser(@RequestBody LoginAttempt login) {
    System.out.println("Login attempt for user " + login.getUserName() + login.getPassword());
    return true;
}

FormHttpMessageConverter which is used for @RequestBody-annotated parameters when content type is application/x-www-form-urlencoded cannot bind target classes as @ModelAttribute can). Therefore you need @ModelAttribute instead of @RequestBody

Either Use @ModelAttribute annotation instead of @RequestBody like this 

     public boolean validateUser(@ModelAttribute LoginAttempt login)

or you can create a separate method form processing form data with the appropriate headers attribute like this:

    @RequestMapping(value="/validate", method=RequestMethod.POST, headers = "content-type=application/x-www-form-urlencoded" produces="application/json")

Just try adding this bean:

<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
    <property name="prefixJson" value="false"/>
    <property name="supportedMediaTypes" value="application/json"/>
</bean>
