Passing in JSON array to spring MVC Controller

Question

I am trying to pass a JSON array into spring MVC Controller like such:

 var myList = new Array(); 
data._children.forEach( function (d) { 
                           


        

Answer 1

You can try

@RequestParam("myList") myList tempmyList

---

@Param myList tempmyList

in addition, class names must begin with a capital letter.

Answer 2

Even I was facing same problem. My client request was right and generated proper json file. but still i was getting same error.

I solved this error using @JsonIgnoreProperties(ignoreUnknown = true) in pojo class.

refer this link. Spring MVC : The request sent by the client was syntactically incorrect

try to add this to you ajax call it should fix the unsupported response :

headers : {
    'Accept' : 'application/json',
    'Content-Type' : 'application/json'
},

this is a full example of ajax call that is working for me :

$.ajax({
            dataType : "json",
            url : this.baseurl + "/dataList",
            headers : {
                'Accept' : 'application/json',
                'Content-Type' : 'application/json'
            },
            data : JSON.stringify(params),
            type : 'POST',
            success : function(data) {
                self.displayResults(data);
            },
            error : function(jqXHR,textStatus,errorThrown ){
                showPopupError('Error','error : ' + textStatus, 'ok');
            }
        });
