javascript - Jackson Faster XML AJAX Submit not working properly @JsonBackReference, @JsonManagedReference -

so i'm using spring boot , i'm trying submit form using ajax, , i'm getting error in console in eclipse (sts), , in chrome console, data submitting fine, it's not following through ajax because tell page reload submit nothing happens when click submit button. when check in mysql database submitted , mapped way want , when refresh browser data submitted shows up.

i'm trying add comment post , assign comment user object. i'll show guys code can see i'm talking about.

so here's user object, have mapped @onetomany annotation along @jsonmanaged annotation.

@onetomany(fetch=fetchtype.eager, cascade=cascadetype.all, mappedby="user") @jsonmanagedreference @jsonignoreproperties(allowgetters=true, value = "user" ) public set<comment> getcomments() {   return comments; } 

i have @ top of user object

@entity @table(name="users") @jsonidentityinfo(generator = objectidgenerators.intsequencegenerator.class, property = "@id") public class user 

here's comment object

@manytoone @jsonbackreference @jsonignoreproperties(allowgetters=true, value = "comments") public user getuser() {     return user; } 

along this

@jsonidentityinfo(generator = objectidgenerators.intsequencegenerator.class, property = "@id") public class comment 

here's ajax, of code allow work thymeleaf, in case you're unfamiliar.

<script th:inline="javascript">          /*<![cdata[*/          var postid = /*[[${post.id}]]*/'1';          var token = $("meta[name='_csrf']").attr("content");         var header = $("meta[name='_csrf_header']").attr("content");          $(document).ajaxsend(function(e, xhr, options) {             xhr.setrequestheader(header, token);         });          $(document).ready(function(){         $("#submit").on("click", function(ev) {             ev.preventdefault();             $.ajax({                 url : "newcomment",                 type : "post",                 data : {                     "postid" : postid,                     "newcomment" : $("#newcomment").val()                 },                 success : function(data) {                     console.log(data);                     location.reload();                 },                 error : function() {                     console.log("there error");                 }              });         });       });     /*]]>*/  </script> 

here's controller

@requestmapping(value="viewcourse/post/newcomment", method=requestmethod.post) public @responsebody post newcomment (@valid @requestparam long postid, @requestparam string newcomment, modelmap model, @authenticationprincipal user user) { post post = postrepo.findone(postid); comment comment = new comment(); comment.setcomment(newcomment); comment.setpost(post);  comment.setuser(user); user.getcomments().add(comment);  comment.setuser(user);  post.getcomments().add(comment); post savedpost = postrepo.save(post);  return savedpost; } 

and here's part of error in eclipse (sts) console, it's pretty long didn't think should post whole thing.
