Spring Mvc将数据从控制器传递到jsp

Question

我正在尝试将数据从控制器类传递给jsp但是当我在服务器上运行它时显示空值但我的id是正确的并且我的查询也返回了期望结果但是当我从jsp获取它时它不显示任何价值。控制台中的错误是500内部服务器错误。 这是我的控制器代码：

@RequestMapping(value = "getmoviereviewbyid/{id}", method = RequestMethod.GET)  
public ModelAndView getMovieReviewByID(@PathVariable("id") String id) throws IOException { 
    ModelAndView
    model = new ModelAndView();         
    MovieReviewModel mrm=new MovieReviewModel();
    mrm=movieReviewDao.getMovieReviewById(Long.valueOf(id));
    model.addObject("review", mrm.getReview());
    model.addObject("movierating", mrm.getRatings());
    model.setViewName("getmoviereviewbyid");        
    return model;
}

这是jsp代码部分：

function selectli(listval,id){
$('#moviename').val(listval);
$('#movierating').val(id);
$('#auto').hide(800);
$('#exist').html("Word already exist!!");
$.ajax({
    url : "/cms/getmoviereviewbyid/"
            + id,
    type : "GET",
    success : function(results) {
        $('#moviereview').val(results.review);
    }
});

}

这是我的道具：

@Override
public MovieReviewModel getMovieReviewById(Long id) {
  return  (MovieReviewModel) getHibernateTemplate().find("from MovieReviewModel where movie_id="+ id);
}

以下是获取ID的代码

@RequestMapping(value = "admin_getmoviereview/{name}", method = RequestMethod.GET)
    public ModelAndView getMovieReview(
            @PathVariable("name") String name)
            throws IOException {
        ModelAndView model = new ModelAndView();

        try {

            if (name != null) {

                List<MovieModel> tagList = new ArrayList<MovieModel>();
                tagList = (List<MovieModel>) movieReviewDao.getMovieReviewByMovie(name);
                        //.findGallery(15441);

                if (tagList.size() > 0) {

                    Map<String, Long> map = new TreeMap<String, Long>();

                    for (Iterator<MovieModel> iterator = tagList.iterator(); iterator
                            .hasNext();) {
                        MovieModel masterModel = (MovieModel) iterator.next();
                        map.put(masterModel.getName(),
                                (long) masterModel.getId());
                    }
                    model.addObject("typemap", map);

                }

            }

        } catch (NullPointerException e) {
            // TODO: handle exception
            e.printStackTrace();
        }

        model.addObject("name", name);
        model.setViewName("admin_getmoviereview");
        return model;

    }

这是jsp

<script>
    $(document).ready(function() {
                    $( "#moviename" ).keyup(function() {
                       if($('#moviename').val().length>1){
                           $.ajax({
                                  url: "/cms/getmoviereviewread?term="+ $('#moviename').val(),
                                  success: function( data ) {
                                      if(data.length>0){
                                            var str ='<ul style="list-style: none;">';

                                                var strtitle="'" +data[i].title + "'";
                                                str+='<li onclick="selectli('+strtitle+','+data[i].id+');">'+data[i].title+'</li>';
                                            }
                                            $('#auto').html(str+'</ul>');
                                            $('#auto').show(800);
                                        }else{

                                  }}
                                });
