Spring MVC Param Error - How to send date request to jsp - spring

Question

I am using Spring MVC 3.4.0. When i tried CRUD example I get this error in my browser console;
HTTP Status 400 - The request sent by the client was syntactically
incorrect.
My codes:
EditBlog.jsp;
<%#taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%# page contentType="text/html; charset=UTF-8" language="java"%>
<%# taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%# taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles"%>
<form action="/testhibernate/edit/${blogID}/" method="POST" name="BLOG">
<h3>TITLE</h3>
<input name="TITLE" type="text" value="${blogList.title}" size="30"/>
<h3>CREATE_DATE</h3>
<input name="CREATE_DATE" type="date" value="${blogList.createDate}" size="30"/>
<h3>TEXT_CONTENT</h3>
<input name="TEXT_CONTENT" type="text" value="${blogList.textContent}" size="30"/>
<br>
<input name="action" type="submit" value="Edit" size="30"/>
</form>
editController ;
package com.basari.testhibernate;
import java.util.Date;
import java.util.Locale;
import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

#Controller
public class editController {
#Autowired
private User_Blog_App deneme1;
#RequestMapping(value = "/edit/{blogID}", method = RequestMethod.GET)
public ModelAndView findBlog(#PathVariable Integer blogID)
{
ModelAndView mav = new ModelAndView("editBlog");
Blog blog= deneme1.findBlog(blogID);
mav.addObject("blogList", blog);
return mav;
}
#RequestMapping(value = "/edit/{blogID}/", method = RequestMethod.POST)
public ModelAndView editBlog(#PathVariable Integer blogID
, #RequestParam( value = "TITLE", required=false) String title
, #RequestParam( value = "TEXT_CONTENT", required=false) String content

) {
Blog blog= deneme1.findBlog(blogID);
blog.setTitle( title );
blog.setTextContent( title );
blog.setCreateDate(date);
this.deneme1.editBlog( blog );
ContactController.logger.debug( "contactPost action called ");
try{
}finally{
}
ModelAndView mav = new ModelAndView("editBlog");
mav.addObject("blogList", blog);
return mav;
}
}
edit Function ;
public void editBlog(Blog blog){
Session session =sessionFactory.openSession();
Transaction tx= null;
try{
tx= session.beginTransaction();
session.update(blog);
tx.commit();
}
catch(HibernateException e){
if (tx!=null) tx.rollback();
e.printStackTrace();
}finally{
session.close();
}
}
And there is no error in my JAVA console. What is wrong?

Answer 1

Try this It will work for you
In your controller
#InitBinder
protected void initBinder(WebDataBinder binder) {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat,false));
}

Answer 2

The error is almost certainly that Spring cannot convert the date you enter in this <input> field
<input name="CREATE_DATE" type="date" value="${blogList.createDate}" size="30"/>
into an argument to pass to
#RequestParam( value = "CREATE_DATE", required=false) Date date
As a result, the request is a Bad Request and Spring returns you a 400 status code.
Add a #DateTimeFormat annotation to your request parameter. For example,
#RequestParam( value = "CREATE_DATE", required=false) #DateTimeFormat("dd-MM-yyyy") Date date
And then make sure your client sends the appropriate format of date. For example
14-01-2014
