I'm using form tag to get information of title and content.
But I can't get any information from form tag.
It happens to me several time. I don't know what is the problem..
this is the controller code
#Slf4j
#Controller
#RequiredArgsConstructor
public class PostController {
private final PostRepository postRepository;
private final MemberService memberService;
#GetMapping("/board/upload")
public String moveToUploadPage(Model model) {
model.addAttribute("uploadPostForm", new UploadPostForm());
return "board/uploadForm";
}
#PostMapping("/board/upload")
public String updateBoard(#ModelAttribute UploadPostForm uploadPostForm, Authentication authentication, Model model) {
log.info("uploadPostForm.title = {}", uploadPostForm.getTitle());
Member member = findMember(authentication);
Post post = new Post(member, uploadPostForm.getTitle(), uploadPostForm.getContent());
postRepository.save(post);
return "/board/board";
}
}
this is html code
<!DOCTYPE html>
<html lang="kr" xmlns:th="http://www.thymeleaf.org">

I added thymeleaf object and variable expressions in html and written #Getmapping and #postmapping methods and separate pojo class. after submitting the data using form.html file it going to another grades.html file but data is not showing what might be the issue.
controller program
#Controller
public class piperscontroller {
List<piedpiper> addGrades= new ArrayList<>();
#GetMapping("/")
public String submitForm(Model model){
model.addAttribute("grades",new piedpiper());
return "form";
}
#PostMapping("/handleSubmit")
public String grademeth(piedpiper grades){
addGrades.add(grades);
return "redirect:/grades";
}
#GetMapping("/grades")
public String finalButton(Model model){
model.addAttribute("grades",addGrades);
return "grades";
}
}
<!DOCTYPE HTML>

here is my form
<!--destinationList List-->
<div class="form-group">
<div class="col-sm-3">
<label for="Destination">Destination</label>
</div>
<div class="col-sm-9">
<input type="text" class="form-control" th:field="*{destinationList[0]}" />
<input type="text" class="form-control" th:field="*{destinationList[1]}" />
<input type="text" class="form-control" th:field="*{destinationList[2]}" />
<input type="text" class="form-control" th:field="*{destinationList[3]}" />
</div>
</div>
<div class="form-group">
<div class="col-sm-9">
<button type="submit" class="btn btn-primary btn-block">Calculate</button>
</div>
</div>
</form>
And I'm going to fill following model
public class PriceSearchDTO {
private List<String> destinationList;
public List<String> getDestinationList() {
return destinationList;
}
public void setDestinationList(List<String> destinationList) {
this.destinationList = destinationList;
}
}
I can do this. But I hard coded number of input fields in the list as above in the view. I need to genarate them dynamically and make the number of element in the list is airbitary.
Try this:
<div class="col-sm-9">
<input type="text" class="form-control" th:each="destination : ${destinationList}" th:field="*{destination}" />
</div>
You are using Iteration in Thymeleaf. In fact, there is a quite complete set of objects that are considered iterable by a th:each attribute.
Like this :
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-4.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<title>Good Thymes Virtual Grocery</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" type="text/css" media="all"
href="../../../css/gtvg.css" th:href="#{/css/gtvg.css}" />
</head>
<body>
<h1>Product list</h1>
<table>
<tr>
<th>NAME</th>
<th>PRICE</th>
<th>IN STOCK</th>
</tr>
<tr th:each="destination: ${destinations}">
<td th:text="${destination}">Onions</td>
</tr>
</table>
<p>
Return to home
</p>
</body>
</html>
And Controller in Spring framework.
#RequestMapping(value = "/")
public ModelAndView showView(ModelAndView mav) {
List<String> destinations = new ArrayList<String>();
destinations.add("elementA");
destinations.add("elementB");
destinations.add("elementC");
mav.addObject("destinations", destinations);
mav.setViewName("/viewName");
return mav;
}
I created a web page displays users information and register a new user. If we try to enter existing user it is showing the error message. when I refresh the page the error is still exist. How to clear the error message when we refresh or when we click reset button.I am using spring Boot Here is my code.

Here is my controller:
#RequestMapping(value = "/registerUser", method = RequestMethod.POST)
public String registrationForNewUSer(#RequestParam Long userId, #RequestParam String userName, Model model)
throws Exception {
//checking whether user already exist
UserModel userInfo = userInfo.findOne(userId);
if (userInfo != null) {
String str = "user already exist" + userId;
model.addAttribute("errorMessage", str);
return usersList(model);
} else {
//
return "redirect:/registerUser/" + userId + "/" + userName;
}
}
#RequestMapping(value = "/usersList", method = RequestMethod.GET)
public String usersList(Model model) {
model.addAttribute("users", userInfo.findAll());
return "usersview";
}
#RequestMapping("/registerUser/{userId}/{userName}")
public ResponseEntity<Object> authentication{
// it does authenticationprocess and add user user in database and redirect to usersview.
}
I am trying to fill a form with values provided by the controller using tags in an app built with spring boot. But I get an error:

I have created a class to match form fields:
public class IndexForm {
private String city_out;
private String city_in;
private String company;
private String date0;
private String date1;
// getters, setters
}
And created a bean in main class (I hope so):
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class Application extends SpringBootServletInitializer {
#Bean
public static IndexForm indexForm() {
return new IndexForm();
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
Controller contains this method:
#RequestMapping("/index")
public String index(#RequestParam(value="e", required=false) List<Integer> errors, Map<String, Object> model) {
model.put("indexForm", new IndexForm());
if (errors != null)
model.put("errors", errors);
return "index";
}
I don't see any differences from examples I have seen, so I would be happy if someone pointed at my mistake.
some newbies do a mistake by making the field as required in order to validate the field is filled or not
e.g in normal html -
input type="text" name="name" required
in spring - form:input path="firstName" required .... here required will not work and so same type of error "equal symbol expected".
Oh. It seems, including jsp tags one in another doesn't work. So, I changed
action="<c:url value="index_search" />"
for
action="index_search"
and received my page without errors.
these are my controllers:
#RequestMapping(value="/requestBooking", method = RequestMethod.GET)
#ModelAttribute("booking")
public ModelAndView requestBooking(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
ModelAndView view = new ModelAndView("requestBooking");
OAuthAuthenticationToken token = (OAuthAuthenticationToken) SecurityContextHolder.getContext().getAuthentication();
if(token.getUserProfile().getAttributes().get("email").toString().matches(".*#nisum.com")==false){

return new ModelAndView("redirect:/j_spring_security_logout?redirectTo=/rejected");
}
VacationBooking booking=new VacationBooking();
String email=token.getUserProfile().getAttributes().get("email").toString();
User user=userImp.getUserByMail(email);
booking.setUser(user); //setting user
System.out.println(booking.getBookingId() + " - " + booking.getUser().getUserId());
view.addObject("booking", booking);
view.addObject("user", token.getUserProfile().getAttributes().get("email"));
return view;
}

When I try to do booking.getUser().getMail() I get null. It is like my "booking" object is null in my post method. Any idea of how I can get my booking with the user object inside in my post controller, so I can call the getUser() method?
