Jackson Faster XML AJAX提交无法正常工作@JsonBackReference，@ JsonManagedReference

标签： javascript java ajax jackson

所以我正在使用Spring Boot并且我正在尝试使用AJAX提交表单，并且我在Eclipse（STS）和Chrome控制台中的控制台中出现错误，但是数据正在提交很好，但是它没有跟随ajax，因为我告诉页面在我提交的时候重新加载，但是当我点击提交按钮时没有任何反应。当我检查我的MySQL数据库时，一切都按照我想要的方式提交和映射，当我刷新浏览器时，我提交的数据显示出来。

我正在尝试为帖子添加评论，并将该评论分配给用户对象。我会告诉你们我的代码，这样你就能看到我在说什么。

所以这是我的用户对象，我用@OneToMany注释和@JsonManaged注释一起映射。

@OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL, mappedBy="user")
@JsonManagedReference
@JsonIgnoreProperties(allowGetters=true, value = "user" )
public Set<Comment> getComments() {
  return comments;
}

我也在用户对象的顶部

@Entity
@Table(name="users")
@JsonIdentityInfo(generator = ObjectIdGenerators.IntSequenceGenerator.class, property = "@id")
public class User

这是我的评论对象

@ManyToOne
@JsonBackReference
@JsonIgnoreProperties(allowGetters=true, value = "comments")
public User getUser() {
    return user;
}

与此同时

@JsonIdentityInfo(generator = ObjectIdGenerators.IntSequenceGenerator.class, property = "@id")
public class Comment

这是我的AJAX，其中一些代码是允许它与Thymeleaf一起使用，以防您不熟悉。

<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 was an error");
                }

            });
        });
      });
    /*]]>*/

</script>

这是我的控制器

@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;
}

这是我在Eclipse（STS）控制台中遇到的错误的一部分，它很长，所以我不认为我应该发布整个事情。

如果有人能够理解为什么这会表现得很奇怪，并且可以让我知道这会很棒。提前谢谢。
