I am getting this error
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute
I am new to spring and still couldn't get what is wrong with this. Please help ! Thank you in advance
When you load the first page itself, I mean the page containing the form, you need to pass an instance of User. This exception is thrown since you have not passed instance of User that you are trying to use in the form. Kindly check.

It is easiest to create a dedicated form data object:
public class EmployeeSearchFormData {
private long employeeId;
// getter and setter
}
In the controller:
#Controller
public class EmployeeController {
#Autowired
private EmployeeService service;
#GetMapping("/")
public String add(Model model) {
model.addAttribute("employeeSearchFormData", new EmployeeSearchFormData());
return "index";
}
#PostMapping("/search")
public String doSearchEmployee(#ModelAttribute("employeeSearchFormData") EmployeeSearchFormData formData, Model model) {
Employee emp = service.get(formData.getEmployeeId());
model.addAttribute("employee", emp);
return "index";
}
}
Thymeleaf template:
<form action="#" th:action="#{/search}" th:object="${employeeSearchFormData}" method="post">
<div alight="left">
<tr>
<label class="form-label" >Employee ID</label>
<td>
<input type="text" th:field="*{employeeId}" class="form-control" placeholder="Employee ID" />
</td>
</tr>
</div>
<br>
<tr>
<td colspan="2"><button type="submit" class="btn btn-info">Search</button> </td>
</tr>
<div alight="left">
<tr>
<label class="form-label" >Employee Name</label>
<td>
<input type="text" th:field="${employee.ename}" class="form-control" placeholder="Employee Name" />
</td>
</tr>
</div>
</form>
Note the use of th:field="${employee.ename}" and not use *{...}. I also removed the hidden field as it does not seem needed to have it to me.
As an alternative, you can have the #PostMapping redirect to /employee/<id> if there is an endpoint available like that:
#PostMapping("/search")
public String doSearchEmployee(#ModelAttribute("employeeSearchFormData") EmployeeSearchFormData formData) {
return "redirect:/employee/" + formData.getEmployeeId();
}
I have a big problem to solve and I don`t see the sollution of this, because IntelliJ not given me any log. Here is the point:
When I try to open the page with form where I put data od employee and address, address form is invisible.
My code:

I get the page like this with no errors
with no address form on the right side od page.
Please help to solve this problem.
You are adding an empty list of addresses to your backing object:
ArrayList<Address> addressesArray = new ArrayList<>();
listOfAddress.setAddresses(addressesArray);
If you want the form to show up, you need to add at least one address so it has something to loop over.
ArrayList<Address> addressesArray = new ArrayList<>();
addressesArray.add(new Address());
listOfAddress.setAddresses(addressesArray);
I think I do this wrong.
When I add index to ArrayList form showed up.
#RequestMapping("/new")
public String addNewEmployee(Model model) {
AddressesList listOfAddress = new AddressesList();
ArrayList<Address> addressesArray = new ArrayList<Address>(2);
addressesArray.add(0, new Address());
addressesArray.add(1, new Address());
listOfAddress.setAddresses(addressesArray);
model.addAttribute("employee", new Employee()).addAttribute("listAddress", listOfAddress);
return "new_employee_form";
}
I want to enter a permanent and correspondence address in the form, accept the form (POST) and save it to class objects. How to do it?
I am writing a page with user registration. Faced a display problem in the form of validation errors
My Controller:
#Controller
public class UIController {
private final Logger log = LoggerFactory.getLogger(getClass());
#Autowired
private UserService service;
#Autowired
private SecurityService securityService;
#Autowired
private UserValidator validator;
#PostMapping(value = "/login")
public String signIn(#ModelAttribute("userForm") UserTo userForm, BindingResult bindingResult, Model model) {
validator.validate(userForm, bindingResult);
User user = service.findByLogin(UserUtil.createNewFromTo(userForm).getLogin());
if (!userForm.getPassword().equals(user.getPassword())) {
log.info("invalid password {}", user);
return "redirect:/login";
}
log.info("signIn {}", user);
securityService.autologin(user.getLogin(), user.getPassword());
return "redirect:/welcome";
}
}
My Validator:
#Component
public class UserValidator implements Validator {
#Autowired
private UserRepositoryImpl userRepository;
#Override
public boolean supports(Class<?> aClass) {
return UserTo.class.equals(aClass);
}
#Override
public void validate(Object o, Errors errors) {
UserTo user = (UserTo) o;
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "login", "NotEmpty");
if (user.getLogin().length() < 6 || user.getLogin().length() > 32) {
errors.rejectValue("login", "Size.userForm.login");
}
if (userRepository.findByLogin(user.getLogin()) != null) {
errors.rejectValue("login", "Duplicate.userForm.login");
}
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "password", "NotEmpty");
if (user.getPassword().length() < 8 || user.getPassword().length() > 32) {
errors.rejectValue("password", "Size.userForm.password");
}
}
}

When debugging in chrome when sending a POST request, a 302 HTTP error appears.
Accordingly, if I set a breakpoint in the controller, then the debug is not processed.
Tell me what could be the problem?
The "form" tag in your jsp does not have "action" attribute.
You should not redirect on errors, because the redirect will erase the binding result. Instead do :
if (!userForm.getPassword().equals(user.getPassword())) {
log.info("invalid password {}", user);
return "login";
}
During form submission, if there is any validation error then form shows the errors messages under the fields. But the actual problem is in another place. I have two entities User and UserDetails. These entities are mapped with each other by bidirectional one-to-one mapping. Validation is working only with the User entity fields but not with the UserDetails entity.

As you can see the image only fields from the User entity is validating but fields those are from the UserDetails are not validating. Please help.

#Valid
