Value of text field in jsp form is coming as null - java

I have a jsp page with two textboxes and one submit button. On getting the input value from the form, the value for the second textbox named as "amount" is coming as null.
This is my jsp page -
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

And this is the formbean from where i am getting the values -
public class AccountFormBean {
private String amount;
private String accountNumber;
private String CreditDebit;
public void setAccountNumber(String accountNumber){
this.accountNumber = accountNumber;
}
public String getAccountNumber() {
return accountNumber;
}
public void setbalance(String amount) {
this.amount = amount;
}
public String getbalance() {
return amount;
}
public void setCreditDebit(String CreditDebit) {
this.CreditDebit = CreditDebit;
}
public String getCreditDebit() {
return CreditDebit;
}
}
The value for account number is coming fine but it is coming as null for amount.

In your AccountFormBean the getter and setter for amount field are not named correctly. They should be named getAmount() and setAmount(String amount) instead of getbalance() and setbalance(String amount). The framework is usinng getter and setter names to map incoming data to bean fields.

You are using this:
<input type="text" name="amount" class="form-control" id="amount" placeholder="Amount">
Here the name of input field is amount so framework expects you to have getAmount() orsetAmount(int amount) method in your java bean (Note the camelcase as well).

Not able to get the MedicineOrder.medicineId and medicineBorder.boxes[*].boxNumber from template to model object.
After lot of searching I didn't find any answer which is solving the issue only using thymeleaf.
To solve this issue I had to add two hidden input field for medicineId and boxNumber on medicineOrder object and populate those input field using javascript as below. Anyway if anyone find the solution by only using thymeleaf, please let me know.
Populated those fields using javascript
<script>
function function__02__number__assignment(_element){
var __element = _element.children[0];
var __tElement1 = __element.children[0];
var __tElement2 = __element.children[1];
// Copy value from 2 to 1
__tElement1.value = __tElement2.value;
}
function function__01__box_traverse(){
var rootElement = document.getElementsByClassName('box-stock-details');
for(var __i=0 ; __i < rootElement.length ; __i++) {
function__02__number__assignment(rootElement[__i]);
}
function_01_01_medicineId();
return true;
}
function function_01_01_medicineId(){
var _00_1_id_src = document.getElementById('00-1-id-src');
var _00_1_id_dest = document.getElementById('00-1-id-dest');
_00_1_id_dest.value = _00_1_id_src.value;

Thymeleaf th:text does not work in some case

I started to work with thymeleaf in a basic project. When I want to display a message in the sign up page the th:text does not work. I used already th:text in other .html files and it works there but in the signUp.html doesn't.
Here is my controller where I set the message:
package com.teszt.thymeleaftest.controller;
#Controller
#RequestMapping("/login")
#AllArgsConstructor
public class MemberController {
MembersService membersService;
#GetMapping("/login")
public String showLoginPage(){
return "/login/login";
}
#GetMapping("/signUp")
public String showSignUpPage(Model theModel){
Members theMember = new Members();
theModel.addAttribute("member", theMember);
return "/login/signUp";
}
#PostMapping("/save")
public String saveMember(#ModelAttribute("member") Members theMember, ModelMap modelMap){
Members tempMember = membersService.findByEmail(theMember.getEmail());
if(tempMember != null){
modelMap.addAttribute("error", "Email is already exist!");
return "redirect:/login/signUp";
}else{
membersService.save(theMember);
//prevent duplication
return "redirect:/login/login";
}
}
}
Here is my signUp.html

Do you have an account? <a th:href="#{/login/login}">Click here</a>
</div>
</body>
</html>
As I mentioned above this is the only html where the th:text does not works, everywhere else is good.
I hope somebody can help me!
When you use a redirect:, you lose all your model attributes (because it's loading a new page). You need to use a FlashAttribute instead. Like this:
#PostMapping("/save")
public String saveMember(#ModelAttribute("member") Members theMember, ModelMap modelMap, RedirectAttributes redirAttrs){
Members tempMember = membersService.findByEmail(theMember.getEmail());
if(tempMember != null){
redirAttrs.addFlashAttribute("error", "Email is already exist!");
return "redirect:/login/signUp";
}else{
membersService.save(theMember);
//prevent duplication
return "redirect:/login/login";
}
}

How to return value in #PostMapping

I'm pretty new in Spring boot and have some problems.
I have automobile and file, when I add automobile data and save it in db, want to upload the file which is connected to automobile by relationship OneToOne but when save automobile in #PostMapping("/saveAutomobile") I could't take this automobileId and to transfer it to #PostMapping("/uploadFile") to do the connection. Do you have any suggestions?

You can use models to store data and use it in your HTML page
for example:-
Controller.java
#GetMapping("/goToViewPage")
public ModelAndView passParametersWithModelAndView() {
ModelAndView modelAndView = new ModelAndView("viewPage");
modelAndView.addObject("message", "Hello from the controller");
return modelAndView;
}
Test.html
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Title</title>
</head>
<body>
<div>Web Application. Passed parameter : th:text="${message}"</div>
</body>
</html>
#PostMapping("/uploadFile")
public ResponseEntity<FileForm> uploadFile(#RequestParam("file") MultipartFile file) {
File dbFile = DBFileStorageService.storeFile(file);
FileForm fileForm = new FileForm(dbFile.getFileName(), file.getContentType(), file.getSize());
return new ResponseEntity<>(fileForm, HttpStatus.OK);
}

Whats the problem here.
After adding the ajax function my dataTable is not appearing also.
Since you already have an action( th:action="#{/saveUser}") for the form submit, it will send the data directly, not via AJAX. In order to make it worked, you need to prevent this default behavior as like below.
$('#btnSave').click(function(e) {
e.preventDefault()
//Then do your stuff
});
It is not working because you have submit button and it directly submits the form.
What you can do it simply remove type="submit" from button and then try.

Neither BindingResult nor plain target object for bean name 'owner' available as request attribute

I am trying to insert data's into database using Spring,Hibernate and MySql. I am getting the following error while inserting data into database
"Neither BindingResult nor plain target object for bean name 'owner' available as request attribute". I tried all possible solutions available but couldn't clear it.
This is my controller
#Controller
public class DataOwnerRegController {
#Autowired(required = true)
DataService dataService;
#RequestMapping(value="/DataOwnerReg",method = RequestMethod.POST)
public String getForm(#ModelAttribute("owner") Model model )
{
model.addAttribute("owner", new Owner());
return "DataOwnerReg";
}
#RequestMapping(value = "/DataOwnerReg")
public ModelAndView registeruser(#ModelAttribute("owner") Owner owner, BindingResult result){
ModelAndView modelAndView = new ModelAndView("DataOwnerReg");
dataService.insertRow(owner);
return modelAndView;
}
}

Please Help in this.
Thanks in advance
There are a couple things wrong with your controller
First you have the #ModelAttribute on a method argument of the type Model which you shouldn't do. Next the method you expect to be invoked on a GET request is going to be invoked on a POST request so basically there will be no model. Finally in your method that should handle the POST request you are returning a ModelAndView but with an empty model, so at that point there is no model anymore and no Owner object.).
I would suggest to fix your controller in the following way
#Controller
#RequestMapping("/DataOwnerReg")
public class DataOwnerRegController {
private final DataService dataService;
#Autowired
public DataOwnerRegController(DataService DataService) {
this.dataService=dataService;
}
#ModelAttribute
public Owner owner() {
return new Owner();
}
#RequestMapping(method = RequestMethod.GET)
public String get() {
return "DataOwnerReg";
}
#RequestMapping(method = RequestMethod.POST)
public String registeruser(#ModelAttribute("owner") Owner owner, BindingResult result){
dataService.insertRow(owner);
return "DataOwnerReg";
}
}
