There are a lot of similar questions to this, I have looked at them but still couldn't figure out what my problem is. Would really appreciate help with this.
This is my controller:
#RestController
#RequestMapping(value = "/game")
public class YatzyController {
#Autowired
private Games games;
#RequestMapping(value = "/{DiceDTO}", method = RequestMethod.POST)
public GameState putGameState(#ModelAttribute("DiceDTO") DiceDTO diceDTO) {
return null;
}
And this is my HTML:
<form method="post" enctype='application/json' action="/game">
<button type="button" onclick="rollDice()">Roll dice</button>
<div>
<input type="text" id="dice1" disabled>
<input type="checkbox" id="keepdice1" value="Keep">
</div>
<div>
<input type="text" id="dice2" disabled>
<input type="checkbox" id="keepdice2" value="Keep">
</div>
<input type="submit">
</form>
Configuration class:
#Configuration
public class YatzyConfiguration {
#Bean
public Games games(){
return new Games();
}
}
Posting to /game
You don't need value = "/{DiceDTO}" in #RequestMapping annotation, because Spring considers it as path's part. So Spring actually maps POST request to /game/somenting path in your case.

#Controller
public class mainController {
#RequestMapping("/login")
public ModelAndView login(Locale locale , Model m) {
System.out.println("modal");
return new ModelAndView ("login");
}
#RequestMapping(path = "/user" , method=RequestMethod.POST)
public String user(#ModelAttribute("user") User user) {
System.out.println(user);
return "user";
}
}
this is login form
<form action="user" method="post" name="user">
<input type="text" name="username" placeholder="uname"/> <br>
<input type="password" name="password" placeholder="password"/> <br>
<input type="date" name="date" placeholder="date"/> <br>
<button type="submit">Submit</button>
</form>
what can I do to submit form using POST method from .html file.
I have post mapping for URL: "/bank/addnew" My controller looks like:
Upon submission the form is submitted to "http://127.0.0.1:8082/banks/%20/banks" However, I need it to go to "http://127.0.0.1:8082/banks/addnew". Thanks for the Help!
#Controller
public class BankController {
#Autowired private BankService bankService;
#GetMapping("/banks")
public String bankList() {
return "bank/bank_list";
}
#PostMapping(value="/banks/addnew")
public String addNew(Bank bank) {
bankService.save(bank);
return "redirect: /banks";
}
}
And my template:
<form method="POST" action="#" th:action="#{/banks/addnew}" >
<div class="form-group">
<label for="recipient-name" class="col-form-label">Bank Name:</label>
<input type="text" class="form-control" id="recipient-name" name="name">
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
The Post Method was actually working okay. I checked it by printing the Model object inside the target controller. However, it was being submitted to the database a NULL value because I didn't initialize getters and setters for my Model. Finally, there was a space in the return string, thus I removed it.
The controller Should have a return statement with no space.
return "redirect:/banks";
I am creating an API by using spring boot. Basically, this API does CRUD operations. And also I created a client that consumes my own API. At first I use Postman to POST data, it successfully insert data to the database and gives me 200 OK code. Then I created web page and I use my API as form action. Then I tried to insert data using the API. But, couldn't. Then I removed #RequestBody from the method and after that I was able to insert data. But the thing is now I can't insert data using Postman. When I try to insert data using Postman, it gives me 200 OK, but nothing insert to the database.
How can I Fix this ??

In one of your #Configuration classes or #EnableAutoConfiguration class create a bean of CommonsRequestLoggingFilter, paste the code. This will log every incoming request
#Bean
public CommonsRequestLoggingFilter logFilter() {
CommonsRequestLoggingFilter filter
= new CommonsRequestLoggingFilter();
filter.setIncludeQueryString(true);
filter.setIncludePayload(true);
filter.setMaxPayloadLength(10000);
filter.setIncludeHeaders(false);
filter.setAfterMessagePrefix("REQUEST DATA : ");
return filter;
}
And in your application.properties file set logging level to DEBUG using logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=
DEBUG
All set! now call your endpoint from the WEB/Postman and check if you find the missing piece.
You need to use #RequestBody :
#RequestMapping(method=RequestMethod.POST, value="/tasks")
public ImModel createNote(#RequestBody ImModel note) {
return TaskRepository.save(note);
}
use the code written below.You need to add #RequestBody before ImModel note
#RequestMapping(method=RequestMethod.POST, value="/tasks")
public ImModel createNote(#RequestBody ImModel note) {
return TaskRepository.save(note);
}
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'm trying to display validation errors in a 'user registration' page built with freemarker template if a controller returns binding errors.
My controller's code is as follows:
#Controller
#RequestMapping("/")
public class UserController {
#Autowired
private UserService userService;
#Autowired
private SecurityService securityService;
#Autowired
private UserValidator userValidator;
#RequestMapping(value = "/registration", method = RequestMethod.GET)
public String registration(Model model) {
model.addAttribute("userForm", new User());
return "registration";
}
#RequestMapping(value = "/registration", method = RequestMethod.POST)
public String registration(#ModelAttribute("useraccount") User userForm, BindingResult bindingResult, Model model) {
userValidator.validate(userForm, bindingResult);
if (bindingResult.hasErrors()) {
return "registration";
}
userService.save(userForm);
securityService.autologin(userForm.getUsername(), userForm.getPasswordConfirm());
return "redirect:/explore";
}
while this is the registration.ftl freemarker template I am trying to build :
<div>
<fieldset>
<h1>Create your Account</h1>
<form id="regForm" class="idealform" action="registration" method="post" name='useraccount'>
Username: <input type="text" name="username" /> <errors path="username" cssClass="error"/><br/>
Password: <input type="text" name="password" /><errors path="password" cssClass="error"/><br/>
<label class="main-label" style="width: 91px;"> </label>
<input type="submit" value="submit">
</form>
</fieldset>
I tried also the solution recommended here:
Displaying Spring MVC validation errors in Freemarker templates
and the registration.ftl becomes:
<#assign form=JspTaglibs["http://www.springframework.org/tags/form"] />
<#macro formErrors>
<#assign formErrors><#form.errors path="*" /></#assign>
<#if formErrors?has_content>
<div id="errors">
<#spring.message "admin.error.globalMessage" />
</div>
</#if>
</#macro>
<div>
<fieldset>
<h1>Create your Account</h1>
<#form.form id="regForm" class="idealform" action="registration" method="post" name='useraccount'>
Username: <input type="text" name="username" path="username" /> <br/>
Password: <input type="text" name="password" path="password" /><br/>
<#formErrors />
<label class="main-label" style="width: 91px;"> </label>
<input type="submit" value="submit">
</#form.form>
</fieldset>
</div>
but still the validation messages are not displayed.
Could you share your thoughts with me on this issue?
Thank you very much.
I rewrote your controller code to something like this:
#Controller
#RequestMapping("/")
public class UserController {
#Autowired
private UserService userService;
#Autowired
private SecurityService securityService;
#Autowired
private UserValidator userValidator;
#RequestMapping(value = "/registration", method = RequestMethod.GET)
public String registration(#ModelAttribute(name = "userForm") User user) {
return "registration";
}
#RequestMapping(value = "/registration", method = RequestMethod.POST)
public String registration(#ModelAttribute(name = "userForm") User user, BindingResult result) {
userValidator.validate(user, result);
if (result.hasErrors()) {
return "registration";
}
userService.save(user);
securityService.autologin(user.getUsername(), user.getPasswordConfirm());
return "redirect:/explore";
}
}
1) There is no need to use model.addAttribute("modelName", model) if you use a constructor without arguments, instead you can use a #ModelAttribute annotation specifying the name attribute (by default the name goes from the class name). You only have to be sure that this model is in a consistent state. Also you need to pass the name exactly the same as you use in your view (freemarker template).
Now "registration.ftl"
...
<#import "/spring.ftl" as spring/>
...
<fieldset>
<h1>Create your Account</h1>
<form id="regForm" class="idealform" action="<#spring.url '/registration'/>" method="post">
<#spring.bind 'userForm.username'/>
Username: <input type="text" name="${spring.status.expression}" value="${spring.status.value?html}"/>
<#list spring.status.errorMessages as error>
<span class="error">${error}</span>
<br>
</#list>
<#spring.bind 'userForm.password'/>
Password: <input type="password" name="${spring.status.expression}" value="${spring.status.value?html}"/>
<#list spring.status.errorMessages as error>
<span class="error">${error}</span>
<br>
</#list>
<label class="main-label" style="width: 91px;"> </label>
<input type="submit" value="submit">
</form>
</fieldset>
...
1)You need <#import "/spring.ftl" as spring/> in order to add spring's user-defined directives that are pretty useful.
2)Use <#spring.bind 'userForm.username'> directive to bind following input to your model. Here "userForm" is your model and "username" is a field that you want to bind. This directive also declares new variable "spring.status" that contains an "expression" variable - for a path, a "value" - to populate the form in case it's returned with errors, and "errorMessages" from BindingResult.
3)If you use a message source to support different languages you should change <span class="error">${error}</span> to something like <#spring.message '${error}'/> otherwise you'll get just message codes.
Hope it helps.
