我有一个简单的模态反馈表单，从我的主页面点击按钮弹出。我将表单值传递给控制器并使用Hibernate插入值。成功插入DB值后，我希望我的模态关闭一些自定义消息，以显示给用户。但我的问题是，它将我重定向到另一个页面error.jsp与404错误。也看起来它没有返回ajax调用成功。我不确定我做错了什么。 请帮忙。 下面是我的控制器，DAO，JS，JSP代码
JSP代码

JS代码
document.getElementById("modal_feedback").addEventListener("submit", function(e) {
var form = this;
var name = form.name.value;
var rating = form.overall.value;
var msg = form.message.value;
if(name == "") {
alert("Please enter your Name");
form.name.focus();
e.preventDefault();
} else if(rating == "") {

$.ajax({

$('#message').html("<h2>FeedbackForm Submitted!</h2>")
.append("<p>We will be in touch soon.</p>")
.hide()
.fadeIn(1500, function() {
$('#message').append("<img id='checkmark' src='images/icon_check.png' />");
});
}
}
});
return false;
}, false);
FeedbackController code
@Controller
public class FeedbackController {
@Autowired
private FeedbackService feedbackService;
private static final Logger logger = Logger.getLogger(FeedbackController.class);
@RequestMapping(value = "/feedbackData")
public @ResponseBody String getFeedbackData(String ratingId, String msg) throws UnsupportedEncodingException{
System.out.println("Inside FeedbackController..");
try{
feedbackService.updateFeedback(ratingId,msg);
return "Y";
}catch(Exception e)
{
logger.error("Exception in Login :" + e);
return "N";
}
}
}
FeedbackDAO实施
@Repository("feedbackDao")
public class FeedbackDaoImpl implements FeedbackDao{
@Autowired
private SessionFactory sessionFactory;
@Override
public int insertFeedback(String ratingId, String msg) {
int status = 0;
Session sess = sessionFactory.openSession();
Transaction tx = null;
try {
tx = sess.beginTransaction();
Feedback fbObj = new Feedback();
fbObj.setFbRatingId(Integer.parseInt(ratingId));
fbObj.setFbSuggestion(msg);
fbObj.setFbTopicId(null);
fbObj.setUserInfo("");
sess.save(fbObj);
tx.commit();
status = 1;
} catch (HibernateException e) {
System.out.println("Exception in feedback record :" + e);
if (tx != null) {
tx.rollback();
}
} finally {
sess.close();
}
return status;
}
}
错误跟踪
Inside FeedbackController..
Hibernate: insert into feedback (fb_rating_id, fb_suggestion, fb_topic_id, user_info) values (?, ?, ?, ?)
