Passing multiple variables in @RequestBody to a Spring MVC controller using Ajax

by

While it’s true that @RequestBody must map to a single object, that object can be a Map, so this gets you a good way to what you are attempting to achieve (no need to write a one off backing object):

@RequestMapping(value = "/Test", method = RequestMethod.POST)
@ResponseBody
public boolean getTest(@RequestBody Map<String, String> json) {
   //json.get("str1") == "test one"
}

You can also bind to Jackson’s ObjectNode if you want a full JSON tree:

public boolean getTest(@RequestBody ObjectNode json) {
   //json.get("str1").asText() == "test one"
