Question

Controller signature (I have tried as requestbody as well) :

@RequestMapping(value = "/Lame", method = RequestMethod.POST)
public
@ResponseBody
boolean getLame(@RequestParam String strToMatchA, @RequestParam String strToMatchB) {}

And this as my json :

{
"strToMatchA": "EN",
 "strToMatchB": "lon"
}

Not working, I receive the error :

org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'strToMatchA' is not present

Removing this first parameter from method signature then makes it work (the method gets called correctly), what should I be doing ?

When I change method parameters to be annotated with @RequestBody I get the following error :

java.io.IOException: Stream closed

Answer 1

Your json is fine but not the controller signature.
Create a class with setters matching the json.
Use it as argument instead of your strings.
Annotate it with requestbody. It should work.
