Question

当我使用JSON在服务器上发送AJAX Post请求时在firebug POST 406不可接受

Response headers
Content-Length  1067
Content-Type    text/html;charset=utf-8
Date    Mon, 02 Dec 2013 11:45:09 GMT
Server  Apache-Coyote/1.1

Request headers
Accept  application/json
Accept-Encoding gzip, deflate
Accept-Language ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3
Content-Length  296
Content-Type    application/json; charset=UTF-8
Cookie  id=8; JSESSIONID=61E68D2A0464C2E5B82F59F921EE598C
User-Agent  Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:25.0) Gecko/20100101 Firefox/25.0
X-Requested-With    
XMLHttpRequest

此请求标识的资源只能根据请求“accept”标题生成具有不可接受特征的响应。

控制器

@RequestMapping(value = "/addcomment.html", method = RequestMethod.POST,produces = MediaType.APPLICATION_JSON_VALUE,consumes = MediaType.APPLICATION_JSON_VALUE,headers="Content-Type=application/json")
    public @ResponseBody MyComment AddComment(@RequestBody MyComment comm, HttpServletRequest request, HttpServletResponse response) throws Exception {

        MyComment myComment = new MyComment();
        String idArticle2 = String.valueOf(comm.getArticleId().getArticleId());
        String comment = comm.getComment();
        String idUser = String.valueOf(comm.getAuthorId().getUserId());


        MyArticle art = new MyArticle();
        art.setArticleId(Integer.parseInt(idArticle2));

        MyUser user = new MyUser();
        user.setUserId(Integer.parseInt(idUser));

        myComment.setParrentId(0);
        myComment.setArticleId(art);
        myComment.setComment(comment);
        myComment.setAuthorId(user);
        myComment.setMyDate(new Date());


        myCommentServ.addComment(myComment);

        return myComment;
}

ajax post request

$('#addcomment').click(function(){
    var idUser = $("#idUser").data("idd");
    var idArticle = $('#idArticle').val();
    var myComment = $('#myComment').val();

   var dataaa = {"id":null,"comment":myComment,"id_author":{"id":idUser,"login":null,"password":null,"email":null,"photo":null},"id_article":{"id":idArticle, "title":null, "description":null,"article":null,"mydate":null,"id_author":null}, "id_parent":0,"mydate":null};
   $.ajax({
url: "http://localhost:8088/MyBlog.ua/addcomment.html",
type: 'POST',
dataType: 'json',
data: dataaa,
contentType: 'application/json',
beforeSend: function(xhr) {  
        xhr.setRequestHeader("Accept", "application/json");  
        xhr.setRequestHeader("Content-Type", "application/json");  
        },
success: function(data) {
    alert("OK");
},
error:function(data,status,er) {
    alert("error: "+data+" status: "+status+" er:"+er);
}
});

当我在服务器上发送json时，我得到406 Not Acceptable，我想从服务器返回json。在Controller方法中，addComment没有输入。如何解决此错误？

Answer 1

我有同样的问题只是“昨天”

您必须从网址中删除.htm部分

自：

@RequestMapping(value = "/addcomment.html", 
            method = RequestMethod.POST,
            produces = MediaType.APPLICATION_JSON_VALUE,
            consumes = MediaType.APPLICATION_JSON_VALUE,
            headers="Content-Type=application/json")
public @ResponseBody MyComment AddComment(@RequestBody MyComment comm, 
                                          HttpServletRequest request, 
                                          HttpServletResponse response) throws Exception {

要：

@RequestMapping(value = "/addcomment", 
            method = RequestMethod.POST,
            produces = MediaType.APPLICATION_JSON_VALUE,
            consumes = MediaType.APPLICATION_JSON_VALUE,
            headers="Content-Type=application/json")
public @ResponseBody MyComment AddComment(@RequestBody MyComment comm, 
                                          HttpServletRequest request, 
                                          HttpServletResponse response) throws Exception {

和

自：

$.ajax({
   url: "http://localhost:8088/MyBlog.ua/addcomment.html",
   type: 'POST',
   dataType: 'json',
   data: dataaa,
   contentType: 'application/json',

要：

$.ajax({
   url: "http://localhost:8088/MyBlog.ua/addcomment",
   type: 'POST',
   dataType: 'json',
   data: dataaa,
   contentType: 'application/json',
