Spring params is not working

Question

Annotation with spring params is not working.

@RequestMapping(value = "/login", method = RequestMethod.PUT)
public @ResponseBody ResponseMsg login(@RequestParam String userName, @RequestParam String password ) 
{
    ResponseMsg responseMsg = CommonUtils.checkParam(userName, password);

    if(responseMsg.getStatus().equalsIgnoreCase("True"))
    {
        responseMsg =  userService.login(userName, password);
    }
    return responseMsg;
}

I'm using this function for get value in put but it shows 400 Bad Request. Any help?

First use firebug to see what parameters that you send to controller. If the parameter names is correct. I think the reason is that the field annotated with @RequestParam that the default is required, it means that the parameters that sent from client must contains them which are userName and passWord, change to this :@RequestParam(value="username" required=false) String userName, @RequestParam(value="password" required=false) String password and try it.

I'm not sure you want to use a post in this scenario. But you could try accessing the header params as follows:

@RequestMapping(value = "/login", method = RequestMethod.PUT)
public @ResponseBody ResponseMsg login(@RequestHeader("username") String userName, @RequestHeader("password") String password ) {
                ResponseMsg responseMsg = CommonUtils.checkParam(userName, password);
                if(responseMsg.getStatus().equalsIgnoreCase("True"))
                    responseMsg =  userService.login(userName, password);
                return responseMsg;
            }
