I am new in Spring MVC and learning about #modelattribute annotation and getting above error.Everything else works fine without modelattribute annotaion. I even tried using #RequestParam instead of #modelattribute and everthing worked fine. But I am not able to understand what is wrong with the code below. Please can anyone help?

You may need to annotate your class not as #Controller but as #ControllerAdvice. A useful page providing an example of the use of #ModelAttribute-- http://www.baeldung.com/spring-mvc-and-the-modelattribute-annotation --comments:
It is also important that you annotate the respective class as
#ControllerAdvice. Thus, you can add values in Model which will be
identified as global. This actually means that for every request a
default value exists, for every method in the response part.
Perhaps you are not adding all attributes in your Student class? In any event, perhaps a default object for Student is not available since #ControllerAdvice is not being used. I hope this helps. But regardless, more useful documentation on the subject can be found on that page I referenced above.

i'm new with spring MVC and i'm trying to perform my first application. my objective is to have one web form used to take a string as input and another web form where i write the string on a web page.
i created the following files:
the controller:
package com.gipeto.app;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.prova.form.Prova;
import com.prova.form.User;
#Controller
public class NewController {
#RequestMapping(value="/secondaPagina", method=RequestMethod.GET)
public ModelAndView goToPage(ModelMap model) {
Prova funziona = new Prova();
funziona.setTest("pippo");
model.addAttribute("prova", funziona);
return new ModelAndView("secondPage","model",model);
}
}
my homepage:
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page session="false" %>
<html>
<head>
<title>Home</title>

<td>sesso</td>
<td>età</td>
</tr>
<tr>
<form:input path="test"/>
</tr>
</table>
<input type=submit value="salva">
</body>
</html>
when i try to run this code i obtain the following error:
HTTP Status 500 – Internal Server Error

14: </tr>
15: <tr>

17: <form:input path="test"/>
18:
19: </tr>
20: </table>
Can you help me to understand where is the issue?
thanks for your help
I think that happens because you don't actually have the form:form tag. Try it like this.
<form:form method="POST">
<table>
<tr>
<td>nome</td>
<td>sesso</td>
<td>età</td>
</tr>
<tr>
<form:input path="test"/>
</tr>
</table>
<input type=submit value="salva">
</form:form>

Thanks in advance!!
This error has nothing to do with <form:select> tag
Still There are few things missing in your code which is resulting this error.
In JSP you are trying to upload file along with form data so you need to have multipartResolver bean defined in spring context from common-fileupload.jar
MultipartResolver Spring
Controller method should be changed like this
#RequestMapping(value="/productlist/addproduct" , method= RequestMethod.POST,consumes = {MediaType.MULTIPART_FORM_DATA_VALUE})
public ModelAndView addProdt(#ModelAttribute("prdt") Product p,BindingResult bindingResult)
This is an old question but In case anyone else experiences the same issue then look how I solved it.
The problem has nothing to do with the post method that was provide. It is thrown by the next page that you are redirecting to ("redirect:/allProduct"). Your ORM could not successfully map the database result to individual objects, this could be caused by not specifying a primary key or having keys that evaluate to null. So visit your database and fix it, make sure you have everything correct in the end.
Error
HTTP Status 400 – Bad Request depctive, malfunction
Type Status Report
Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; nested in logs
I have got the same error while redirecting from one handler to another, my handler was handling request but it couldn't redirected to another Page.
return"redirect:/employeeReport";
I tried all methods but that couldn't solve my issue.
Then I just found that there was sequence mismatch in Entity property and form Property. Just matched all my Entity property and cleaned my project issue resolved.
Advice: Map all fields of your Entity class properly with your form, clean project and run again. Even if there is no issue in mapping of Entity's field this error comes then simply clean project and rerun might work.
I am working on spring mvc application, there I have a form where a user can change his password. I am validating this form by using default spring form validation (see validator code below).

You can see that when the form has errors, I am returning control back to the same JSP.
My problem is that I am unable to trace the bug/error where my spring form validation is working fine, but when I am trying to display the errors which are defined in my properties file.
You should not explicitly invoke validator. Use this validation method instead:
#Valid #ModelAttribute("forName") FormName formName,
BindingResult bindingResult, Model model,
RedirectAttributes redirectAttributes, HttpSession session

<script>
function popup() {
window.open("../popup/searchspring", 'window', 'width=200,height=100');
}
</script>
and in controller you have to do something like this which will navigate your request to desired page cause in spring controller decide the navigation of view pages
#RequestMapping(value = "/searchspring", method = RequestMethod.GET)
public String view(Model model) throws Exception {
EmployeeBO employeeBO = new EmployeeBO();
model.addAttribute("employeeBO", employeeBO);
return "EmployeeForm";
}
I have solved it in my Spring MVC Project by the following way:
The Controller class is like this:
#RequestMapping(value = "viewPicture.dispatch", method = RequestMethod.GET)
public String viewPicture(HttpServletRequest request, RequestParam(value="fileName")String fileName, #RequestParam(value="filePath")String filePath) {
//some code..
return "viewDCPicture"; //the View where it will go.
}
The JSP page on which I have written JS and Html code also, is like this:
<script>
function viewDCPicture(fileName){
var filePath = $("#filePath").val();
//Setting the left and right size of the pop-up window
var left = (screen.width/2)-(1100/2);
var top = (screen.height/2)-(170/2);
$.ajax({
method: "GET",
url : "viewPicture.dispatch?fileName=" + fileName + "&filePath=" + filePath,
success : function(response) {
var strURL = "viewPicture.dispatch?fileName=" + fileName + "&filePath=" + filePath + "";
window.open(strURL, 'viewDCPicture', 'width=1100, height=600, resizable=1, scrollbars=yes, location=0, status=0, titlebar=no, toolbar=0, addressbar=0, top='+top+', left='+left+'');
},
error : function(e) {
}
});
}
</script>
<table>
<tr>
<td align="right"><label>SUPPORTING DOCS.</label></td>
<c:forEach items="${attachmentDtlList}" var="data">
<td>
${data.key}
<input type="hidden" id="filePath" value="${data.value}">
</td>
</c:forEach>
</tr>
</table>
In my template.xml where the JSP files are mapped with the perticular name = "viewDCPicture", I have made changes like this:
I have created a template inside the template.xml file as:
<definition name = "viewDocTemplate" template = "/viewDoc.jsp">
<put-attribute name = "body" value = "" />
</definition>
And used it inside the temlate.xml file as:
<definition extends = "viewDocTemplate" name = "viewDCPicture">
<put-attribute name = "body" value = "/enquiry_management/viewDCPicture.jsp" />
</definition>
The viewDoc.jsp file which will help the Pop-up window file viewDCPicture.jsp to bind it inside body of viewDoc.jsp is as follows:
<%# page language = "java" contentType = "text/html; charset = UTF-8"
pageEncoding = "UTF-8"%>
<%# taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core"%>
<%# taglib uri = "http://tiles.apache.org/tags-tiles" prefix = "tiles"%>
<%# taglib uri = "http://www.springframework.org/tags" prefix = "spring"%>
<!DOCTYPE html>
<html>
<head>
<meta charset = "UTF-8">
<title>Insert title here</title>
</head>
<body>
<%-- Adding spring attribute for adding body, header, footer etc tag. --%>
<spring:htmlEscape defaultHtmlEscape = "true" />
<tiles:insertAttribute name = "body" />
</body>
</html>
The viewDCPicture.jsp file is like this:
<html>
<head>
</head>
<table align="center" class="headingSpas">
<tr>
<td class="headingSpas">
<table width="100%" align="center" bgcolor="#CCCCCC">
<tr>
<td colspan="2" align="center" class="headingSpas" >
<img alt="" src="<%=path%>" border="0" align="top" />
</td>
</tr>
</table>
</td>
</tr>
</table>

#Controller
#RequestMapping("/search")
public class SearchEmployeeController {
private EmployeeServiceImpl employeeServiceImpl;
public void setEmployeeServiceImpl(EmployeeServiceImpl employeeServiceImpl) {
this.employeeServiceImpl = employeeServiceImpl;
}
#RequestMapping(value = "/searchspring", method = RequestMethod.GET)
public ModelAndView view(
#ModelAttribute("employeeForm") EmployeeForm employeeForm)
throws Exception {

model.addObject("employeeForm", employeeForm);
model.setViewName("Search");
return model;
}
#RequestMapping(value = "/employeeNo", method = RequestMethod.POST)
public ModelAndView searchByEmpNo(
#ModelAttribute("employeeForm") EmployeeForm employeeForm)
throws Exception {
ModelAndView model = new ModelAndView();
model.addObject("employeeForm", employeeForm);
Long i = employeeForm.getEmployeeNumber();
EmployeeBO employeeBO = employeeServiceImpl.getEmployee(i);
System.out.println(employeeBO);
model.addObject("employeeBO", employeeBO);
model.setViewName("EmployeeDetail");
return model;
}
#RequestMapping(value = "/empByName", method = RequestMethod.POST)
public ModelAndView searchByEmployeeName(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {

model.addObject("employeeForm", employeeForm);
List<EmployeeBO> employeeBOs = employeeServiceImpl

model.addObject("listEmployeeBO", employeeBOs);
model.setViewName("EmployeeList");
return model;
}
#RequestMapping(value = "/empByDeptId", method = RequestMethod.POST)
public ModelAndView searchByDeptId(

model.addObject("employeeForm", employeeForm);
List<EmployeeBO> employeeBOs = employeeServiceImpl
.getAllEmployeeByDeptid(employeeForm.getDepartmentId());
model.addObject("listEmployeeBO", employeeBOs);
model.setViewName("EmployeeList");
return model;
}
}

As an alternative to configuring different endpoints for the same form based on the button clicked (using either separate forms in the HTML or changing the form action via JS), you could use the params attribute of the RequestMapping annotation to further narrow the form submission to a specific controller method based on the value of the button (or any other form submitted field). See the Spring documentation on this for more detail.
Using this strategy, your request mappings would look something like this:
#RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindByName")
public ModelAndView searchByEmployeeName(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {
...
#RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindByDeptNO")
public ModelAndView searchByDeptId(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {
...
#RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindById")
public ModelAndView searchByEmpNo(
#ModelAttribute("employeeForm") EmployeeForm employeeForm)
throws Exception {
...
i dont know how to map map the request to particular method with different value of submit button
Have each search in a separate form. Each form mapped to different controller methods. Like this:
<form:form action="empById" method="post" commandName="searchBean">
Employee_ID
<form:input path="employeeNumber" />
<input type="submit" name="method" value="FindById" />
</form:form>
<form:form action="empByName" method="post" commandName="searchBean">
Employee_Name
<form:input path="firstName" />
<input type="submit" name="method" value="FindByName" />
</form:form>
<form:form action="empByDeptNo" method="post" commandName="searchBean">
Employee_Name
<form:input path="departmentId" />
<input type="submit" name="method" value="FindByDeptNO" />
</form:form>
Now different search requests will map to the correct controller method.
i get the by default 0 value on my EmployeeId input field i dont know why its happening
Before you add an instance of EmployeeForm to the model, initialize it to what ever default value you would like to have seen in the search page.
