In my program, I am generating dynamic form names based on the number of feedbacks I get. I am then taking the satisfaction, comment and feedbackId inputs. They are different for each iteration. This is giving me an IllegalStateException error.
My HTML form is:
<form action="#" th:action="#{/heart2heart/token/__${tokenId}__/}" method="post">
<div class="table-responsive">
<table class="table table-striped table-bordered table-hover table-condensed">

<div class="form-group">
<button type="submit" name="addRow" th:text="#{button.submit}"
class="btn btn-primary btn-md">Submit</button>
</div>
</div>
</form>
My controller is:
#RequestMapping(value = "/{tokenId}/", method = RequestMethod.POST)
public String addSatisfaction(#PathVariable int tokenId, #Valid ReceiptForm receiptForm, BindingResult result, Model model) {
try {
for (SatisfactionForm satisfactionForm : receiptForm.getFeedbacks()) {

Feedback feedback1 = heart2heartService.getFeedbackById(feedback);
Resolution resolution = new Resolution();
resolution.setId(feedback1.getReceipt().getResolutions().get(0).getId());
resolution.setSatisfactionLevel(satisfactionForm.getSatisfaction().name());
resolution.setComment(satisfactionForm.getComment());
heart2heartService.addSatisfaction(resolution);
model.addAttribute("success", "Satisfaction added for tokenId " + tokenId);
}
} catch (Exception e) {

try {
model.addAttribute("feedbacks", heart2heartService.getFeedbacksByToken(token));
} catch (Exception e) {
logger.error("Exception :: ", e);
}
return "heart2heart/closeFeedback";
}
My forms are:
public class ReceiptForm {
private List<SatisfactionForm> feedbacks = new ArrayList<SatisfactionForm>();
public List<SatisfactionForm> getFeedbacks() {
return feedbacks;
}
public void setFeedbacks(List<SatisfactionForm> feedbacks) {

}
public Satisfaction getSatisfaction() {
return satisfaction;
}
public void setComment(String comment) {
this.comment = comment;
}
public void setFeedbackId(int feedbackId) {
this.feedbackId = feedbackId;
}
public void setSatisfaction(Satisfaction satisfaction) {
this.satisfaction = satisfaction;
}
}
I am getting the following error:
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'feedbacks[0]' available as request attribute
How do I fix this?
You did not specify the form-backing bean in your Thymeleaf template.
You are using the *{} operator to access fields of the bean, but Thymeleaf does not know
which bean you want to use. To resolve the error, add a th:object to your form.
Assuming that heart2heartService.getFeedbacksByToken(token) returns a ReceiptForm your form would look like this:
<form action="#" th:action="#{/heart2heart/token/__${tokenId}__/}" method="post" th:object="${feedbacks}">

I'm currently developing an online banking application where you can buy stocks. It is being built with spring boot and the front-end is html/css.
I am using the YahooFinance API to get stock quotes but I need to refresh my page to get the live stock quotes, how can I automatically update the page every 30 seconds to get the new prices for each stock?
Also, is there a way I could implement this using Threads?
Banking Controller
#GetMapping("/banking/stocks")
public String stocks(Model model) {
model.addAttribute("stock", new StockDto());
try {
List<Stock> stocks = stockService.getDefaultStocks();
model.addAttribute("stocks", stocks);
} catch (IOException e) {
e.printStackTrace();
}
return "stocks.html";
}
StockServiceImpl:
#Service
public class StockServiceImpl implements StockService {
private String[] startingStocks = { "AAPL", "BABA", "MSFT", "AXP", "BA", "AMD", "TSLA", "MA", "SHOP", "GOOGL",
"KL" };
#Override
public Stock getStock(String stockName) throws IOException {
Stock stock = YahooFinance.get(stockName);
return stock;
}
#Override
public Map<String, Stock> getStock(String[] s) throws IOException {
Map<String, Stock> stocks = YahooFinance.get(s);
return stocks;
}
#Override
public List<Stock> getDefaultStocks() throws IOException {
Map<String, Stock> stocks = YahooFinance.get(startingStocks);
List<Stock> stockList = new ArrayList<Stock>();
for(String s : startingStocks) {
stockList.add(stocks.get(s));
}
return stockList;
}
}

You can exploit STOMP protocol and web sockets using spring boot.
For reference:
https://www.baeldung.com/spring-websockets-send-message-to-user
on back end side you can use
#Autowired
SimpMessagingTemplate messagetemplate;
public void somemethod(String strParam){
while (true){
// build string or json whatever you need to send
messagetemplate.convertAndSend("/blabla/blabla",strParam);
Thread.sleep(30*1000);
}
}
on front end side you have to use stomp.js
<script src="https://cdnjs.cloudflare.com/ajax/libs/stomp.js/2.3.3/stomp.js">
<script type="text/javascript">
function load(){
var stompClient = Stomp.client("ws://localhost:8080/ws");
stompClient.connect({}, function (frame) {
stompClient.subscribe('/blabla/blabla', function (message) {
// do something here
});
});
}
lastly, part of html where you want to call on load
<html>
<body onload="load()">
</body>
</html>
You can create an #Scheduled method that can call this API request every 30 seconds to get data and update your Front-End.
#Scheduled(fixedRate = 30000)
public void updateStocksElement() {
//Call your /banking/stocks rest endpoint
}

I'm getting an error NotReadablePropertyException: Invalid property 'userIds' of bean class [...ListOfIds]... And I'm not sure why. If I remove the th:field attribute on the checkbox, the table fills in properly. I've tried with th:field="*{requestIds}" and th:field="*{requestIds.ids}"
What I'm trying to do is collect the list of ids from the selected checkboxes and pass them back to the controller for the post.
Form
public class ListOfIds {
List<Long> ids = new ArrayList<>();
public List<Long> getIds() { return ids; }
// I've tried both set methods by themselves and together.
public void setIds(List<Long> ids) { this.ids = ids; }
public void setIds(Long[] ids) { this.ids = Arrays.asList(ids); }
}
Request bean
public class Request {
long id;
String name;
String phone;
String email;
// Getters/Setters
}
Controller
#GetMapping("/myTable")
public ModelAndView getMyTable(ModelAndView mav) {
mav.setViewName("myTable");
List<Request> requests = service.getRequests();
mav.addObject("requests", requests);
mav.addObject("requestIds", new ListOfIds());
return mav;
}
#PostMapping("/myTable")
public ModelAndView postRequests(ModelAndView mav, #ModelAttribute("requestIds") ListOfIds ids) {
...
}
html page
...
<form method="post" th:action="#{/myTable}" th:object="${requestIds}">
<table class="table ...">
<thead>
<tr>
<th><input type="checkbox" class="selectall" data-target="requests-all"/></th>
<th>Name</th>
<th>Phone</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<tr role="row" th:each="request : ${requests}">
<td>
<input type="checkbox" name="requestId" data-target="requests-all"
th:value="${request.id}" th:field="*{requestIds}"/>
</td>
<td th:text="${request.name}"></td>
<td th:text="${request.phone}"></td>
<td th:text="${request.email}"></td>
</tr>
</tbody>
</table>
<button class="btn btn-primary show-selected">Process</button>
</form>
...
<script>
$(document).ready(function() {
$('button').click(function(e) {
if !(confirm("Are you sure you wish to process these requests")) {
e.preventDefault();
}
});
});
</script>
...
So the answer is that name and th:field don't play nice together.
I made the following changes and it worked:
Controller
#PostMapping("/myTable")
public ModelAndView postRequests(ModelAndView mav,
#ModelAttribute("requestIds") Long[] ids) {
...
}
html
<form id="postMyTable" method="post" th:action="#{/myTable}">
<table ...
<input type="checkbox" name="requestId" data-target="requests-all"
th:value="${request.id}"/>
...
<script>
$(document).ready(function() {
$('button').click(function(e) {
if !(confirm("Are you sure you wish to process these requests")) {
e.preventDefault();
} else {
$("#postMyTable").submit();
}
});
});
</script>

I am trying so many time but unable to fixed the issue, And browse also but did't get any proper help, so please help to do items
I NEED HELP PLEASE SOME BODY HELP ME...!
Thank you in advance
I think the problem is in your jsp file.
You need to set the index of each list element.
<c:forEach items="${List2}" var="as" varStatus="vs">
<tr class="rule">
<td><input type="hidden" name="ruleList[${vs.index}].id" value="${as.rule.id}" /> ${as.rule.id}</td>
<td><input type="hidden" name="ruleList[${vs.index}].ruleName" value="${as.rule.ruleName}" /> ${as.rule.ruleName}</td>
<td> <input id="one" class="datepicker" type="text" name="ruleList[${vs.index}].startDate" size="11" height="0.10"></td>
<td> <input id="two" class="datepicker" type="text" name="ruleList[${vs.index}].endDate" size="11" height="0.10"></td>
<td>
<table border="1">
<c:forEach items="${as.ruleAssignmentParameter}" var="asss" varStatus="assignments">
<tr>
<td><input type="hidden" name="ruleList[${vs.index}].ruleAssignmentParameter[${assignments.index}].parameterName" value="${asss.parameterName}" > ${asss.parameterName}</td>
<td><input type="hidden" name="ruleList[${vs.index}].ruleAssignmentParameter[${assignments.index}].overwriteValue" value="${asss.overwriteValue}" /> ${asss.overwriteValue}</td>
</tr>
</c:forEach>
</table>
</td>
</tr>
</c:forEach>
Also in your controller (POST method) you are trying to get the object identified by "SpringWeb" but should be "ruleListContainer", same name you have in your form tag
The problem was you had a list into RuleAssUI and you was not accesing correctly, you need 2 loops and indexes, one for each list.
Here is the key:
ruleList[${vs.index}].ruleAssignmentParameter[${assignments.index}].parameterName
I have controller which adds Computer assigned to User by admin. User can have several assigned Computers and it is implemented through Spring MVC Multiple Selection. But I’ve little issue with displaying of info after updating. It shows as many users in List of users as many computers were assigned. I think problem not in JSP and debuggers shows nothing so I’ll very appreciate your help.
Here is my AdminUserUpdateController.java
#Controller
public class AdminUserUpdateController {
#InitBinder("userForm")
private void initBinder(WebDataBinder binder) {
binder.setValidator(updateValidator);
binder.registerCustomEditor(Set.class, "computers", new CustomCollectionEditor(Set.class) {
#Override
protected Object convertElement(Object element) {
String pcName = null;
if (element instanceof String && !((String) element).equals("")) {
try {
pcName = (String) element;
Set<Computer> computerSet = new LinkedHashSet<>();
computerSet.add(computerService.getComputerByName(pcName));
new UserForm().setComputers(computerSet);
} catch (NumberFormatException e) {
logger.info("Error in element");
logger.info("Element was " + ((String) element));
}
}
return pcName != null ? computerService.getComputerByName(pcName) : null;
}
});
}
...............
#RequestMapping(value = "/adminEdit/{userId}", method = RequestMethod.GET)
public String updateView(#PathVariable("userId") Integer userId,
UserForm userForm,
ModelMap model) {
userForm.setUser(userService.getUserById(userId));
model.addAttribute("userForm", userForm);
model.addAttribute("computers", computerService.getAllComputers());
return "adminUserUpdate";
}
#RequestMapping(value = "adminEdit.do/{userId}", method = RequestMethod.POST)
public ModelAndView updateUserProcess(#ModelAttribute(value = "userForm")
UserForm userForm,
#PathVariable("userId") Integer userId,
BindingResult result, Model model) {
User user = userService.getUserById(userId);
model.addAttribute("computers", computerService.getAllComputers());
model.addAttribute("userForm", userForm);
updateValidator.validate(userForm, result);
return updatingUser(user, model, userForm);
}
private ModelAndView updatingUser(User user, Model model,
UserForm userForm) {
if (isEmailExists(userForm, user)) {

return new ModelAndView("adminUserUpdate");
}

userService.updateUser(user);
return new ModelAndView("redirect:/adminPage", "user", user);
}
private void fillForm(UserForm userForm, User user) {
userForm.setUserId(user.getUserId());
userForm.setLogin(user.getLogin());
userForm.setRegDate(user.getRegDate());
// userForm.setComputers(computer);
userForm.setRole(roleService.findByName(user.getRole().getRoleName()));
