How to send a single word(no key) JSON to springMVC?

Question

I have an API for front side,I use postman to send a single number 8.

@RequestMapping(value="/query",method=RequestMethod.POST)
@ResponseBody
public String query(@RequestBody Integer number ){  

    return dao.query(number);
}

but now the front side say they can not send a single word with no key-value in json,I don't want to create an object just use that once to binding, how can I do this?

Have a look at requestparam

@RequestMapping(value = "/query", method=RequestMethod.POST)
@ResponseBody
public String query(@RequestParam("number") Integer number){
  return dao.query(number);
}

The request should be like /query?number=8

Change Integer to String and you are good to go without doing anything else. Hope this helps you.

@RequestMapping(value="/query",method=RequestMethod.POST)
 @ResponseBody
 public String query(@RequestBody String number ){  

      return dao.query(number);
 }
