Required String parameter is not present error in Spring MVC

On the server side you expect your request parameters as query strings but on client side you send a json object. To bind a json you will need to create a single class holding all your parameters and use the @RequestBody annotation instead of @RequestParam.

@RequestMapping(value = "events/add", method = RequestMethod.POST)public void addEvent(@RequestBody CommandBean commandBean){    //some code}

Here is a more detailed explanation.

I had the same issue.. I solved it by specifying the config params in the post request:

var config = {    transformRequest : angular.identity,    headers: { "Content-Type": undefined }}$http.post('/getAllData', inputData, *config*).success(function(data,status) {    $scope.loader.loading = false;})

config was the parameter I included and it started working.. Hope it helps :)

Spring Boot Code

@RequestMapping(value = "events/add", method = RequestMethod.POST)public void addEvent(@RequestParam(value = "start_date") String start_date, @RequestParam(value = "end_date") String end_date, @RequestParam(value = "text") String text, @RequestParam(value = "userId") String userId){    //some code    }

Postman Request Link to be send: Add the parameters and value using Parmas in postman and see the below request link.

http://localhost:8080/events/add?start_date=*someValue*&end_date=*someValue*&text=*someValue*&userId=*someValue*
