I have the below table in a .JSP page:
<form:form method="post" action="update.dtt" id="contactForms" modelAttribute="contactForms" >
<c:forEach items="${pList}" var="cf">
<tr>
<td align="center"><c:out value="${cf.fname}" /></td>
<td align="center"><c:out value="${cf.lname}" /></td>
<td align="center"><c:out value="${cf.cprovider}" /></td>
<td align="center"><c:out value="${cf.id}" /></td>
<td align="center"><c:out value="${cf.phone}" /></td>
<td><input type="submit" value="Update Contact"/></td>
</tr>
</c:forEach>
</form:form>
I'm iterating over the list (this is list of objects) and adding an Update Contact button for each record in the list. How can I pass on the particular instance (object) to the controller when the Update button is clicked?
The controller I have is as below. However I'm getting null.
#RequestMapping(value = "/user/update.dtt", method = RequestMethod.POST)
public String updateView(#ModelAttribute("contactForms") Banks bank, HttpServletRequest request, HttpServletResponse response, Model model) {
System.out.println("*First Name*" + bank.getFname());
//......
return "detailBank"; //name of jsp file
}
You'll need to have a hidden form field for each information you want to send to the server.
Since you have one button for each row, you should also have one form for each row. So the <form:form> and </form:form> lines should be inside the <c:forEach>, and not outside.
You need reference the instance by position, accessing to the element of the list by position.
list[i].name
list[i].surname
where list is the element in your pojo.

I have a controller which sets few values to a model and sends to jsp. In jsp i need to show those values(as labels) along with additional values from user as input values. When i submit the jsp i only get valid values that user has entered and the values set earlier by controller is null.
JSP
<form:form
action="${pageContext.request.contextPath}/admin/deviceAction.html"
modelAttribute="deviceData">
<table class="gridtable" width="500px">
<tr>
<td>Device Name : </td>
<td>${deviceData.deviceName}</td>
</tr>
<tr>
<td>Model Name : </td>
<td>${deviceData.modelName}</td>
</tr>
<tr>
<td>Serial No : </td>
<td>${deviceData.serialNo}</td>
</tr>
<tr>
<td>Device Id : </td>
<td>${deviceData.deviceId}</td>
</tr>
<tr>
<td>Status : </td>
<td>${deviceData.statusCode}</td>
</tr>
<tr>
<td>Action : <span class="required">*</span></td>
<td>
<form:select path="deviceAction" >
<form:option value="" label="--- Select ---" />
<form:options items="${model.actionList}" />
</form:select>
</td>
</tr>
</table>
<input type="submit" value="Submit" id="btn_submit">
</form:form>
Controller:
public ModelAndView beforeSubmit() {
ModelAndView modelView = new ModelAndView();
DeviceData deviceData = new DeviceData();
deviceData.setDevicePk("123");
deviceData.setAccessToken("abcwetrwertewrtetr");
deviceData.setDeviceId("deferterterterterwtetetertg");
deviceData.setDeviceName("test");
deviceData.setEnrolledDate("7-8-13");
deviceData.setModelName("test1");
deviceData.setSerialNo("test2dsfgdfgdfg");
deviceData.setStatusCode("test3");
List<String> actionList = getActionList();
Map<String, List<String>> model = new HashMap<String, List<String>>();
model.put("actionList", actionList);
modelView.addObject("deviceData", deviceData);
modelView.addObject("model", model);
modelView.setViewName("admin/tokenSearchResult");
}
public ModelAndView afterSubmit() {
#ModelAttribute("deviceData") DeviceData deviceData, BindingResult result) {
logger.info("#################device datas are : " + deviceData.getDevicePk() + "###### " + deviceData.getDeviceAction());
return new ModelAndView();
}
deviceData.getDevicePk() is null
Only the drop down value is having valid value. Other values displayed in the screen are received as null.
Edit:
Till now i have found only one solution:
<form:input path="deviceName" readonly="true" />
But this way UI does not looks good. The editable and non editable values mixup in the screen. Looking for a better answer
Finally i am using hidden parameters to solve the problem.
Example:
<td>${deviceData.deviceName}</td>
is replaced by:
<td><form:hidden path="deviceName"</td>
By this way it helps me to avoid any css work(which i am not much comfortable)
If anyone get a better solution kindly post it here
You need to make them into form inputs using the Spring form tags in much the same way as you have for the form:select. If they are not editable by the user, you can always disable them.
You can simple hide those input. For example :
<input type="hidden" name="VehSeriesModelId" value="${vehDetailsVM.id }">
This way, you can get the data to the controller and the user will also not be able to edit the value. On the other hand, your form will also not show it :)
I am working with two classes that have a relationship many-to-many. I insert data in both tables, the relationship is usually registered in JoinTable. My question is, how to display the data from both tables in the same form?
Here is my controller:
#Controller
public class RecipeController {
#Autowired
private ReceitaService receitaService;
#RequestMapping(value = "/novaReceita.do", method = RequestMethod.POST)
public String createRecipes(#ModelAttribute("Receita") Receita receita, BindingResult resultReceita,
#ModelAttribute("Tag") Tag tag, BindingResult resultTag, #RequestParam String action, Map<String, Object> map) {
receita.getTag().add(tag);
receitaService.addReceita(receita);
map.put("receita", receita);
map.put("receitaList", receitaService.getAllReceita());
return "listRecipes";
}
Here is where I am having problems because I can only show data for a single table.
public String editForm(#PathVariable("id") int id, ModelMap map) {
map.addAttribute("receita", receitaService.getReceita(id));
return "updateRecipes";
}
Finally, the JSP page to display the data entered:
<c:url var="url" value="/receita/${receita.id}"/>
<form:form action="${url}" method="GET" commandName="receita">
<table width=80% >
<tr>
<td><strong>ID </strong></td>
<td><form:input path="id" disabled="true" class="input-small"/></td>
</tr>
<tr>
<td><strong>Title </strong></td>
<td><form:input path="titulo" class="input-xlarge"/></td>
</tr>
<tr>
<td valign=top><strong>Desc probl</strong></td>
<td><form:textarea path="desc_prob" class="input-xlarge" rows="3" /></td>
</tr>
<tr>
<td valign=top><strong>Desc soluc</strong></td>
<td><form:textarea path="desc_soluc" class="input-xlarge" rows="6" /></td>
</tr>
<tr>
<td><strong>Tag</strong></td>
<td> <form:input path="tag" disabled="true" class="input-small"/></td>
</tr>
</table>
</form:form>
What is missing to be able to show the data from both tables?
Thank's.
For single column/property you can use <form:input/>For Many to One you can use <form:select/>For One to Many you can use <form:select multiple='true'>In your case, you have to select a single ID first for the one side of the relationship which is receita and then display all the tags in that receita, so i think it counts as One to Many at that point. So in your case, try to use this tag:<form:select path="tag" multiple="true"/>
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.
I am developing an application in which i am using spring framework 3.1.1 and rest api. In it i have developed one rest controller which will on receiving "GET" request of url "/rest/host/{id}" will redirect the control to my view(form). Now after user fills up the form the posted data is also handled using rest. But in the method which i have written to handle post request all the parameters i am getting in one string which i want to parse and insert into the database. Can anybody tell which is the proper way to parse this spring data ? I can do it using String.split("&") but i don't think it is correct way to do that. Here is my code.
<form:form method="POST" action="/nagios-sms-1.0/rest/snooze/host/" commandName="snoozeBean">
<table width="100%" border="5" cellpadding="0" cellspacing="0">
<tr>
<td align="center">
<table width="50%" border="5">
<tr>
<td colspan="3"></td>
</tr>
<tr>
<td width="30%"><form:label path="contactNumber">Enter host address</form:label></td>
<td width="30%"><form:input path="contactNumber" /></td>
<td />
</tr>
<tr>
<td width="30%"><form:label path="snoozeTimeoutValue">Enter Snooze time</form:label></td>
<td width="30%"><form:input path="snoozeTimeoutValue" /></td>
<td />
</tr>
<tr>
<td colspan="3">
<div id="buttons"
style="margin-left: 20Px; margin-right: 100px;">
<input type="submit" value="ok" /> <input type="reset" />
</div>
</td>
</tr>
</table>
</td>
</tr>
</table>
REST code..
1) GET handler method
#RequestMapping(value = "/host/{hostId}", method = RequestMethod.GET)
public String snoozeHost(#PathVariable int hostId, ModelMap map) {
Snooze snooze = new Snooze();
snooze.setHost_id(hostId);
map.put("snoozeBean", snooze);
return "host";
}
2) POST handler method
#RequestMapping(value = "/host", method = RequestMethod.POST)
#ResponseBody
public String snoozeHostOK(#RequestBody String payload) {
// i want to parse this payload data which contains my form fields.
System.out.println("data : " + payload);
return payload;
}
Any kind of help will be appreciated. Thanks in advance.
Instead of request body you can use #ModelAttribute and get all the form data bind in one pojo(snooze) filled by Spring Framework on post of the form.
You need to declare snooze in your get and post request mapped method as #ModelAttribute. That will let you get all your values from the form.
UPDATE
See your modified code here.
GET handler method
#RequestMapping(value = "/host/{hostId}", method = RequestMethod.GET)
public String snoozeHost(#PathVariable int hostId, #ModelAttribute Snooze snooze, ModelMap map) {
snooze.setHost_id(hostId);
return "host";
}
POST handler method
#RequestMapping(value = "/host", method = RequestMethod.POST)
#ResponseBody
public String snoozeHostOK(#ModelAttribute Snooze snooze) {
// you can use the setter methods of snooze object to retrieve the field values.
return payload;
}
Hope this helps you. Cheers.
I have some problems with taking a parameters from jsp page, when method POST occurs.
My JSP page looks like this:
....
<table border="1">
<tr>
<th>name</th>
<th>check</th>
</tr>
<c:forEach items="${things}" var="pair">
<tr>
<td>${things.name}</td>
<td><INPUT TYPE="CHECKBOX" NAME=items VALUE=${things.id} ></td>
</tr>
</c:forEach>
</table>
<form method="post">
<input type="submit" value="Check all" />
</form>
So, I want to take all checked "things" in table. In controller class I something like this (written in Spring):
....
#RequestMapping(method = RequestMethod.POST)
public String sumbitForm(#RequestParam("items") String[] items){
if(items!= null){
for(String item: items){
....
}
}
return "redirect:myPage";
}
But my app don't want to work with such RequesParam. It doesn't put the values of items parameter to it. (this method I took here http://www.go4expert.com/forums/showthread.php?t=4542)
Also I tried using #ModelAttribute instead of #RequesParam. When I'm using it, my app don't give a errors, but it also couldn't correctly put the "items" to this parameter.
Any ideas?
P.S. May be you know more better method of taking list of parameters from JSP page for using their values (like taking checked items)?
Your table is outside of the <form></form> so when submitting, it doesnt send anything.
