I am getting below error when I am hitting '/signup' API after '/index' API. I have gone through many links. I found mentioned in various resources that the issue is the order of #Valid and BindingResult param needs to be maintained and I see it already in my code still I am unable to find what exactly the problem is. Please help me resolve this issue:

The problem is that you have #Valid annotation on the #GetMapping method:
#GetMapping("/signup")
public String showSignUpForm(#Valid JourneyFoodOrder journeyFoodOrder) {
return "add-journeyFoodOrder";
}
This indicates that JourneyFoodOrder already should be valid when showing the form for the first time, which is never true. Use this in stead:
#GetMapping("/signup")
public String showSignUpForm(JourneyFoodOrder journeyFoodOrder) {
return "add-journeyFoodOrder";
}
I personally find it clearer to do this:
#GetMapping("/signup")
public String showSignUpForm(Model model) {
model.addAttribute("journeyFoodOrder", new JourneyFoodOrder());
return "add-journeyFoodOrder";
}
But both will work fine.
Additional notes:
You need to use #ModelAttribute for your form data object parameter in the #PostMapping method:
public String addJourneyFoodOrder(#Valid #ModelAttribute("journeyFoodOrder") JourneyFoodOrder journeyFoodOrder, BindingResult result, Model model) {
...
}
After fixing the #GetMapping method, you will run into another problem because add-journeyFoodOrder.html has this line that should be removed:
<span th:if="${#fields.hasErrors('name')}" th:errors="*{name}"></span>
You might want to use a dedicated form data object to bind to the HTML form instead of using your entity directly. See Form handling with Thymeleaf for more information on that.

I am getting started with Springboot and am unable to propagate validation results (errors) back to the thyme template. I have a typical setup: #Entity object, #Service, and #Repository. Here are the sections of my Controller and index template (and its form). UserVital, UserBlood, etc. are the data objects mapped to the DB tables using hibernate. Hope this information is enough for the members to point me in the right direction.
Data Object
#Entity
#Table(name = ".....")
public class UserVital {
#NotNull(message = "Height (Feet) cannot be null")
#Range(min = 0, max = 15, message = "Height (Feet) must be greater than 0")
#Column(name = "feet", nullable = false)
private int heightInFeet;
.............
}
Controller
#GetMapping("/")
public String getUsers(Model model) {
UserVital vital = new UserVital();
UserGrithMeasurements grith = new UserGrithMeasurements();
UserBloodChemistry blood = new UserBloodChemistry();
List<Category> categories = categoryService.getAllCategories();
model.addAttribute("categories", categories.get(0));
model.addAttribute("vital", vital);
model.addAttribute("grith", grith);
model.addAttribute("blood", blood);
return "index";
}
#PostMapping("/add")
public String addData(#Valid UserVital vital, BindingResult vitalValidationResult,
#Valid UserGrithMeasurements grith, BindingResult grithValidationResult, #Valid UserBloodChemistry blood,
BindingResult bloodValidationResult, Model model) {
if (vitalValidationResult.hasErrors() || grithValidationResult.hasErrors()
|| bloodValidationResult.hasErrors()) {
return "index";
} else {
model.addAttribute("successMsg", "Details saved successfully!!");
return "index";
}
}
Thyme Form
<form class="tab-content" method="POST" th:action="#{/add}">
<div class="form-group row">
<label for="height" class="col-sm-2 control-label" th:text="#{height}"></label>
<div class="col-sm-2">
<input type="number" class="form-control" id="feet" th:attr="placeholder=#{feet}"
th:field="${vital.heightInFeet}">
</div>
<div class="form-group col-sm-12">
<label for="neck" class="col-sm-2 control-label" th:text="#{neck}"></label>
<div class="col-sm-2">
<input type="number" class="form-control" id="systolic" th:attr="placeholder=#{inches}"
th:field="${grith.neck}">
<div class="col-sm-2">
<input type="number" class="form-control" id="ldl" th:field="${blood.ldl}">
.....
</form>
Question: As you can see I have multiple BindingResult objects. Each BindingResult object holding the validation results of the respective data object (vitalValidationResult holds validation result of UserVital object vital, etc.). Now, how do I write "th:if" statements in the template that will allow me to check if there are any errors in the fields.
Thanks.
I have solved the problem by encapsulating the required form fields in a div and then placing "th:object=${objectName}" in the div.
<form >
<div class="tab-pane active text-center" id="tab_1_1" th:object=${vital}>
<div class="tab-pane active text-center" id="tab_1_2" th:object=${grith}>
</form>
I am trying to show validation errors in my form, but I am not able to implement it.
I am trying to pass null values, I get the hibernate validation message but I am not able to see form validation?
Here is my code:
#RequestMapping(value = "/register", method = RequestMethod.POST)
public String saveForm(#Valid Users users,Model model,Errors errors) {
if(errors.hasErrors()) {
return "registerPage";
}
else {
model.addAttribute("message","Registered................");
System.out.println("Save Users TEST------------------------------------>");
userRepository.save(users);
return "register-success";
}
}
Here is the exception:

}
Here is my html form(Using thymeleaf):

Found my reason , i was not passing the correct parameters in my saveForm Controller-
#RequestMapping(value = "/register", method = RequestMethod.POST)
public String saveForm(#ModelAttribute("registerCommand") #Valid Users users, BindingResult bindingResult, Model model){
if(bindingResult.hasErrors()) {
return "registerPage";
}
else {
userRepository.save(users);
return "register-success";
}
}
Note-If you are using BindingResult,it should be exactly after the bean.
It is only BindingResult where the order matters. It must follow the bean that is being validated so that Spring knows where to put any validation errors.

Field 'salary' on object User may be null
Check what data you are passing in user object while saving it, there might be salary value is going as null. As you have used #valid on Users , it will not take null or empty value in the input request data
I am new in SPING and web developing.
I am developing the test task - quote book (without authorizing). I have two entities: Quote and Author. There is the code:
#Entity
#Table(name="authors")
public class Author {
#Id
#SequenceGenerator(name="author_id_seq", sequenceName="author_id_seq", allocationSize=1)
#GeneratedValue(strategy = GenerationType.SEQUENCE,generator = "author_id_seq")
#Column(name = "id")
private long id;
#Column(name = "nick_name")
private String nickName;
public Author() {
}
public Author(long id, String nickName) {
this.id = id;
nickName = nickName;
}
/*
Getters and Setters
*/
}
Quote:
#Entity
#Table(name = "quotes")
public class Quote {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "quotes_id_seq")
#SequenceGenerator(name="quotes_id_seq", sequenceName="quotes_id_seq", allocationSize=1)
#Column(name = "id")
private long id;
#Column(name = "content")
private String content;
// #Temporal(TemporalType.DATE)
#Column(name = "date")
private LocalDate date;
#ManyToOne
#JoinColumn(name = "author")
private Author author;
public Quote() {
}
public Quote(long id, String content, LocalDate date, Author author) {
this.id = id;
this.content = content;
this.date = date;
this.author = author;
}
/*
Getters and Setters
*/
}
My Thymeleaf template contains form with two input fields(for quote.content and for quote.author.nickName) and select with existing authors. I want to see the behavior, when i fill input for author, content and if author is not existing in authors table, my application add the row in this table with specified by value from input nickName and generated id. But the problem is in getting unexpected result for me from Thymeleaf template. Template pass to controller the Quote object with author, which nickname is null instead of value from my input. There is thymeleaf template code of my form:
<form action="#" th:action="#{/newQuote}" th:object="${quote}" method="post">
<div class="form-row">
<div class="form-group col-md-3">
<label class="sr-only" for="inputNick">Nick Name</label>
<!--/*#thymesVar id="author" type="hello.entity.Author"*/-->
<input type="text" class="form-control" id="inputNick" th:field="*{author.nickName}"
placeholder="enter Nick Name">
</div>
<div class="form-group col-md-6">
<select id="nickNames">
<th:block th:each="author : ${allAuthors}">
<option th:text="${author.nickName}">Nick Name</option>
</th:block>
</select>
</div>
<div class="form-group col-md-12">
<label for="postContent">Your Quote:</label>
<input type="text" class="form-control" id="postContent" th:field="*{content}"
placeholder="quote text">
</div>
</div>
<div class="form-group col-md-2">
<input type="submit" value="Add Quote"/>
</div>
<div class="form-group col-md-2">
<input type="reset" value="Reset"/>
</div>
</form>
Controller methods:
#GetMapping("/newQuote")
public String showAuthors(Model model){
model.addAttribute("allAuthors",authorService.findAll());
model.addAttribute("quote", new Quote());
return "newQuote";
}
#PostMapping("/newQuote")
public String addQuote (#ModelAttribute Quote quote) {
quote.setDate(LocalDate.now());
quoteRepository.save(quote);
return "redirect:/";
I've tried:
to add Author object in GetMapping, pass it in newQuote template,
pass from it to PostMapping - no effect. Null in nickname.
to create and insert author object in quote object, pass to
template, pass to postmapping. no effect
I know that i can create DTO class with field nickname insteadof author field and convert it into my entity class in postmapping method of controller. But i think that it is "bad practice" way. I think, that i made wrong steps,may be, when tried to change author object and pass it from thymeleaf to controller. And also i suppose, that there is no way to realize this logic in this situation. i dont know where is the truth. Please, help me in finding it.
P.S: sorry for my bad english
So, the answer is asking how to add a quote and it's author at the same time. With a select approach is impossible, since our author doesn't exists. And simple way to achieve this, is changing your quote entity and adding #Cascade(CascadeType.PERSIST) to the author field in quote. This will automatically persist the author with your quote.
These would be the changes to your code that you would required to accomplish this.
Update
Since, the last solution didn't work, we will try sending an additional parameter to our controller, to avoid receiving a null, instead of the author's nickname.
Controller
#PostMapping("/newQuote")
public String addQuote (#ModelAttribute Quote quote,
#RequestParam("nickName") String nickName) {
// This will automatically persist your quote and it's author.
quote.setDate(LocalDate.now());
Author author = new Author();
author.setNickName(nickName);
quoteRepository.save(quote);
}
Quote Entity
#Entity
#Table(name = "quotes")
public class Quote {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "quotes_id_seq")
#SequenceGenerator(name="quotes_id_seq", sequenceName="quotes_id_seq", allocationSize=1)
#Column(name = "id")
private long id;
#Column(name = "content")
private String content;
#Column(name = "date")
private LocalDate date;
#ManyToOne
#Cascade(CascadeType.PERSIST)
#JoinColumn(name = "author")
private Author author;
// Getters and Setters
}
Important, make sure to notice that we are adding a new annotation #Cascade(CascadeType.PERSIST) to our author field.
HTML
Here we will simply remove the unnecessary select.
<form action="#" th:action="#{/newQuote}" th:object="${quote}" method="post">
<div class="form-row">
<div class="form-group col-md-3">
<label class="sr-only" for="inputNick">Nick Name</label>
<!--/*#thymesVar id="author" type="hello.entity.Author"*/-->
<input type="text" name="nickName" class="form-control" id="inputNick" placeholder="enter Nick Name"/>
</div>
<div class="form-group col-md-12">

I am trying to create a form with 3 fields within the class LoginForm: usuario, senha, msgLogin.
I receive the fields usuário and senha from the input boxes and then I try to redirect to the same page with the same fields plus the field MsgLogin. But I've not been able to update the msgLogin field and I don't understand why.
These are the code:
HTML:
<form id="frmLogin" class="form col-md-12" action="#" th:action="#{/login}" th:object="${loginForm}" method="post">
<div class="form-group">
<label for="usuario" class="col-md-1">Usuário: </label>
<input type="text" id="usuario" placeholder="Email" th:field="*{usuario}"/>
</div>
<div class="form-group">
<label for="senha" class="col-md-1">Senha: </label>
<input type="password" id="senha" placeholder="senha" th:field="*{senha}"/>
</div>
<div class="row">
<button id="entrar">Entrar</button>
</div>
<div class="row">
<div id="msgLogin"></div>
<p th:text="${loginForm.msgLogin}" />
</div>
</form>
The Controller:
#RequestMapping("/")
public String init(#ModelAttribute LoginForm loginForm) {
Logger.getAnonymousLogger().info("Tela Inicial.");
return "home";
}
#PostMapping("/login")
public ModelAndView entrar(LoginForm loginForm) throws IOException {
Logger.getAnonymousLogger().info("Entrando no Internet Banking.");
service.login(usuario, senha);
ModelMap model = new ModelMap();
loginForm.setMsgLogin("I want to update that value!");
model.addAttribute("loginForm", loginForm);
return new ModelAndView("redirect:/", model);
}
Class using Lombok:
#Getter
#Setter
public class LoginForm {
private String usuario;
private String senha;
private String msgLogin;
}
A redirect send a 302 HTTP status back to the browser to resubmit using a new url, so it resubmits the same two fields to the new url. There's no expectation of payload data in the 302 response.
In your Controller, change the last line in your entrar method to: return new ModelAndView("/login", model);
I am woring on an Spring Web application with the CURD operation for the Entity Department, this is the handler for processing the submit of a new Department:
#RequestMapping(value = "/", method = RequestMethod.POST)
public String addSubmit(#Valid Department department, BindingResult result,SessionStatus status) {
if (result.hasErrors()) {
return "department/add";
} else {
departmentService.save(department);
status.setComplete();
return "redirect:/departments/" + department.getId();
}
}
Model:
#Entity
public class Department extends BaseNamedEntity {
#NotNull
#NotEmpty
private String description;
...
}
And the form:
<form:form method="post" action="${fmURL}" class="form-horizontal" commandName="department">
<form:hidden path="id"/>
<spring:bind path="name">
<div class="control-group ${status.error ? 'error' : ''}">
<label class="control-label">Name</label>
<div class="controls">
<form:input path="name"/>
<span class="help-inline">${status.errorMessage}</span>
</div>
</div>
</spring:bind>
<form:form>
However, once I submit the form with empty field, normally, the errorMessage should be displayed and the related div should be add a class with error, however I can not found the error message.
What's going on?
BTW, the example is derive from Spring-petclinic project.
