I've a spring form and when I click a submit button I would like to send a list of elements previously updated.
Here's the jsp :
<form:form method="post" modelAttribute="listeBlocs" action="saveFiche">
<c:forEach var="oneBloc" items="${listeBlocs}" varStatus="status">
<h5 class="col m12 s10">${oneBloc.typeBloc}</h5>
<tr>
<td><textarea name="listeBlocs[${status.index}].blocContenu" >${oneBloc.blocContenu}</textarea></td>
</tr>
</c:forEach>
<input type="submit" value="saveFiche" />
</form:form>
Here's the destination Controller:
#RequestMapping(value="/saveFiche", method = RequestMethod.POST)
private ModelAndView updateBloc(#ModelAttribute("listeBlocs") List<Bloc> lblocs) {
BlocDAO blocDAO = new BlocDAO();
for (Bloc b : lblocs) {
System.out.println("------------\nNouveau bloc : " + b.getblocContenu());
blocDAO.update(b);
}
return new ModelAndView("confirmation_update");
}
Any suggestions ?

I have sent data from jsp page to controller. It shows error.
The origin server did not find a current representation for the target
resource or is not willing to disclose that one exists.
This is my controller::::
#GetMapping(value = "/createdistrict")
public ModelAndView createdistrict(Locale locale, Model model) {
List<Division> allDivisionList = new ArrayList<Division>();
allDivisionList = this.districtService.listdivisions() ;
Map<Integer,String> allDivision = new LinkedHashMap<Integer,String>();
for( int i=0 ; i < allDivisionList.size() ; i++) {
//System.out.println(" division id ::::::::::" + allDivisionList.get(i).getId() + " division name:::::::::" + allDivisionList.get(i).getName());
allDivision.put(allDivisionList.get(i).getId() , allDivisionList.get(i).getName());
}
return new ModelAndView("createdistrict" , "allDivision" , allDivision);
}
#RequestMapping(value="/adddistrict/{division}")
public String addDistrict(#ModelAttribute("district")District district, ModelMap model ,#RequestParam("division") int division) {
System.out.println("id:::::::::::::::::::" + division);
this.districtService.adddistrict(district, division);
return "redirect:districtlist";
}
This is my jsp page::::
<form method="POST" action="/farmvill/adddistrict" modelAtribute="district">
<table class="create-table table table-hover">
<tr>
<td>
Division
</td>
<td>
<select id="division" name="division">
<c:forEach items="${allDivision}" var="allDivision">
<option class="dropdivision" value="${allDivision.key}">${allDivision.value }</option>
</c:forEach>
</select>
</td>
</tr>
<tr>
<td>

<td>
<input type="text" id="name" name="name" path="name"></input>
</td>
</tr>
<!-- End of single tr -->

<!-- End of table -->
<div class="button-set text-right">
<button type="submit" class="btn site-btn filled-btn" id="savebutton">save</button>

What I should do now?
Remove division from mapping path. it's a regular request parameter
#RequestMapping(value="/adddistrict")
public String addDistrict(#ModelAttribute("district")District district, ModelMap model ,#RequestParam("division") int division) {
Can somebody help me to get value from certain input using spring controller.
I have 2 input data, and I just need a value from one of these inputs:
<input type="text" name="data01" />
<input type="text" name="data02" />
I just want to retrieve a value from "data01".
I just have used
(HttpServletRequest) request.getParameter("data01")
Or
#RequestParam(value="data01") Integer data01
but the value is null.
Can somebody help me
EDIT:
jsp:
<table>
<tr>
<input type="text" name="data01" />
<input type="text" name="data02" />
</tr>
</table>
controller:
#RequestMapping(value = "/user", method=RequestMethod.GET)
public String showAllData(ModelMap model, HttpServletRequest request) {
String retrievedData = request.getParameter("data01");
System.out.println("data= " + retrievedData);
model.addAttribute("data", new data());
return "data";
}
The retrievedData value is null.
You should be able to get the parameter using this method
<form action="/user" method="get">
<table>
<tr>
<input type="text" name="data01" />
<input type="text" name="data02" />
<input type="submit" value="submit"/>
</tr>
</table>
</form>
and in the controller
#RequestMapping(value = "/user", method=RequestMethod.GET)
public String showAllData(String data01, ModelMap model) {
// your logic here
}
and from the code you have posted. You are casting the parameter to HttpServletRequest
request.getParameter("data01") //returns String as default.
Integer.parseInt(request.getParameter("data01");
From your comment at #user1516735 answer, you cannot use it outside of the form tag. Unless you include it in the parameter from ajax or append the value of "name01" in the url as /user?name01=value
You will get the value of data01 by using the below code:
request.getParameter("data01");
Here request is of type HttpServletRequest. Make sure your input control is inside form tag.
I want to bind a List using ModelAttribute. The list contains objects of type Transaction each of which contains transactionid (type int). This is my controller code:
#RequestMapping(value = "/approvecreditdebit.do", method = RequestMethod.POST)
public ModelAndView doActions(HttpServletRequest request,
#ModelAttribute("clc") Clc transactionList, BindingResult result,
ModelMap model) {
/*
* switch (action) { case "approve":
*/
System.out.println("Obj = " + transactionList.getClass());
System.out.println("Val = " + transactionList.getTransactionList());
Users users = new Users();
return new ModelAndView("internal","internal",users);
}
This is my jsp code:
<form:form action="approvecreditdebit.do" method="POST"
modelAttribute="clc">
<table border="1">
<tr>
<th>no</th>
<th>ID</th>
</tr>
<c:forEach items="${clc.transactionList}"
var="transaction" varStatus="status">
<tr>
<td>${status.index}</td>
<td><input name = "transaction[${status.index}].transactionId"
value="${transaction.transactionId}" /></td>
</tr>
</c:forEach>
</table>
<br>
<br>
<center>
<input type="submit" value="approve" />
</center>
</form:form>
This is the Clc class:
public class Clc{
private List<Transaction> transactionList;
public List<Transaction> getTransactionList() {
return transactionList;
}
public void setTransactionList(List<Transaction> transactionList) {
this.transactionList = transactionList;
}
}
The value of transactionList is not being set to the values received from the form. I receive the following error:
Request processing failed; nested exception is java.lang.NullPointerException
I tried searching for the solution on google and got a lot of solutions from stackoverflow but none of them seem to work.
Try something like this (notice the use of <form:input>). I just tried it on a simple Spring MVC app and it works (list is not null and has the values from the form when I try to access it in my POST method).
<c:forEach var="transaction" varStatus="status" items="${clc.transactionList}">
<tr>
<td>${status.index}</td>
<td><form:input path="transactionList[${status.index}].id" /></td>
</tr>
</c:forEach>
I am using Spring.AjaxEventDecoration to dynamically populate a drop down on my JSP but it is throwing an error as it cannot bind to the original model. I have been researching this for a while and I do not think this is possible but it seeems like it should be hence this post.. Help me out somebody!
OK My controller dumbed down looks like this,
#Controller
#RequestMapping(value = "/cis/crimeProperty/")
public class CrimePropertyController
{
#RequestMapping(value = "/manageView", method = RequestMethod.GET)
public ModelAndView managePropertyDetails(Long propertyId) throws DAOException
{
Map<String, Object> model = new HashMap<String, Object>();
CrimePropertyVO crimePropertyVO = new CrimePropertyVO();
model.put("crimePropertyVO", crimePropertyVO);
return new ModelAndView("cis.crime.property.edit", model);
}
#RequestMapping(value = "/changeItemList", method = RequestMethod.POST)
public ModelAndView retrieveItemList(String propertyClass)
{
Map<String, Object> model = new HashMap<String, Object>();
..call service to get list of items from class..
model.put("propertyItemList", propertyItemList);
return new ModelAndView("/cis/property/crime_property_item", model);
}
}
I am using tiles so my tile definition looks like this,
<definition name="cis.crime.property.edit" template="/WEB-INF/jsp/cis/property/manage_crime_property.jsp">
<put-attribute name="itemListFrag" value="/WEB-INF/jsp/cis/property/crime_property_item.jsp"/>
My (manage_crime_property.jsp) JSP looks like so,
<form id= "changeList" action="${pageContext.request.contextPath}/smvc/cis/crimeProperty/changeItemList" method="post">
<select id="propertyClassChange" path="propertyClass">
<option value="" label="-Please Select-"/>
<option value="CLO" label="CLOTHING"/>
<option value="TOL" label="TOOLS"/>
</select>
</form
<form:form modelAttribute="crimePropertyVO" action="${pageContext.request.contextPath}/smvc/cis/crimeProperty/saveProperty" method="post">
<table class="genericOutlinedTable" style="width: 100%;">
<tr>
<td><b>Item</b></td>
<td>
<tiles:insertAttribute name="itemListFrag" flush="true" ignore="false"/>
</td>
</tr>
<tr>
<td><b>Make</b></td>
<td><form:input path="propertyMake" size="20" maxlength="20"/></td>
<td><b>Model</b></td>
<td><form:input path="propertyModel" size="15" maxlength="15"/></td>
</tr>
</form:form>
<script type="text/javascript">
Spring.addDecoration(new Spring.AjaxEventDecoration({
elementId:'propertyClassChange',
event:'onchange',
formId:'changeList',
params: {fragments: 'itemListFrag'}
}));
My (crime_property_item.jsp) JSP fragment looks like this,
<span id="itemListFrag">
<form:select path="propertyItem">
<form:option value="" label="-Please Select-">
<c:forEach var="itemList" items="${propertyItemList}">
<form:option value="${itemList.propertyCode}" label="${itemList.propertyCode}" />
</c:forEach>
</form:select>
</span>
Its all configured correctly and when I change the first drop down it calls my controller changeItemList method which returns my JSP frag and list of items to make up the options but I get a server error ...
Neither BindingResult nor plain target object for bean name propertyItemavailable as request attribute
I've tried having just the options tags in my frag but that doesn't work and I've tried using the spring:bind tag and normal select but can't get that to work either.
Many Thanks in advance for any help with this.
I am trying to accomplish the following:
I have a list of fruits, that are stored in a table with two columns "id", "name" and "color".
Next to each fruit, I got a "modify" button. What I want to do here is being able to display the fruit in a form and being able to modify the "name" and "color" attributes.
I don't understand why, but when I click the "modify" button, the form is being displayed but the properties of the fruits that I clicked are not.
Here is the code:
Controller:
#RequestMapping(value = "/fruit/modify", method = RequestMethod.POST)
public String modifyFruit( #RequestParam("id") int id, ModelMap model) {
Fruit fruit = fruitManager.getFruitById(id);
model.addAttribute("fruit", fruit);
return "redirect:/modifyfruit";
}
#RequestMapping(value = "/modifyfruit", method = RequestMethod.GET)
public String showAddForm(#ModelAttribute("fruit") Fruit fruit, ModelMap model) {
model.addAttribute("fruit", fruit);
return "/secure/modifyfruit";
}
Here is the modify button that I am displaying next to each fruit in my list:
<td>
<c:url var="modifyUrl" value="/fruit/modify.html"/>
<form id="${fruitForm}" action="${modifyUrl}" method="POST">
<input id="id" name="id" type="hidden" value="${fruit.id}"/>
<input type="submit" value="modify"/>
</form>
</td>
Here is the modifyfruit.jsp that I am using to display the form that I want to populate:
<body>
<form:form method="post" commandName="fruit">
<table width="95%" bgcolor="f8f8ff" border="0" cellspacing="0"
cellpadding="5">
<tr>
<td align="right">Name:</td>
<td><form:input path="title" value="${fruit.name}"/></td>
</tr>
<tr>
<td align="right">Color:</td>
<td><form:input path="color" value="${fruit.color}"/></td>
</tr>
</table>
<br>
<input type="submit" align="center" value="Post Ad">
</form:form>
</body>
Your redirect is simply going to that new URL without any request params being added. Therefore your fruit ID is being discarded, which is why nothing gets displayed.
The redirect seems pointless - why not return the same view name string as the GET version instead?
To redirect with the params, try:
return "redirect:/modifyfruit?id=" + id;
EDIT: just noticed you have added the Fruit to the model - this does not get transferred in a redirect and wouldn't work anyway.
