I'm using a simple Spring form with mustache. However the data is not received in Spring controller. login.getId(), login.getPass() are always received as null in controller. Any clues if something have to be fixed in template or controller?
My template and controller code as below.
<form class="form-signin" id="loginForm" action="{{{appCtxt}}}/login" method="post">
<label for="inputEmail" class="sr-only">Email address</label>
<input type="email" name="{{id}}" id="id" class="form-control" placeholder="Email address" required autofocus>
<label for="inputPassword" class="sr-only">Password</label>
<input type="password" name="{{pass}}" id="pass" class="form-control" placeholder="Password" required>
<button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
</form>
Controller
#Controller
public class LoginController {
private LoginService loginService;
#Autowired
public void setLoginService(LoginService loginService) {
this.loginService = loginService;
}
#RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView index(HttpServletRequest request, Model model) {
ModelAndView result = new ModelAndView();
model.addAttribute("login", new Login());
result.addObject("resources", request.getContextPath() + "/resources");
result.addObject("appCtxt", request.getContextPath());
// return "redirect:/users";
result.setViewName("home");
return result;
}
#RequestMapping(value = "login", method = RequestMethod.POST)
public String login(Login login, HttpServletRequest request){
boolean status = loginService.verifyLogin(login.getId(), login.getPass());
if(status == true) {
return "redirect:/users";
}
else
{
return "error";
}
}
}
Instead of the name="{{pass}}" you can use name="pass" assuming you Login class contains a field with the very same name. Another thing is that you need '#ModelAttribute' annotation near the Login parameter.
For easier understanding how it works, please consider following example:
Student.java
package me.disper.model;
public class Student {
private String name;
private String surname;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
}

Problem:
Request method 'GET' not supported.
I am writing a page with user registration. Faced a display problem in the form of validation errors
My Controller:
#Controller

#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 {

#Override
public boolean supports(Class<?> aClass) {
return UserTo.class.equals(aClass);
}
#Override
public void validate(Object o, Errors errors) {

ValidationUtils.rejectIfEmptyOrWhitespace(errors, "login", "NotEmpty");
if (user.getLogin().length() < 6 || user.getLogin().length() > 32) {

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";
}
I'm facing an issue with spring and thymeleaf, i'm trying to fill a form with data from an entity called cliente, but i'm getting a Whitelabel Error Page message in the browser and this message in the console
Neither BindingResult nor plain target object for bean name 'cliente' available as request attribute
this is the Cliente

this is the controller method

Cliente cliente = null;
if(id > 0) {
clientedao.findOne(id);
model.put("cliente", cliente);
model.put("titulo", "Editar Cliente");
return "form";
}
else {
return "redirect:/listar";
}
}
this is the ClienteDaoImpl.java method
#Override
public Cliente findOne(Long id) {
// TODO Auto-generated method stub
return em.find(Cliente.class, id);
}
this is the Dao interface method
public Cliente findOne(Long id);
and this is the form

i'm setting the cliente in the controller method and i'm using th:object in the form, so i don't know what i'm doing wrong, any help would be helpul, thanks in advice
Instead of put(), try using the recommended approach to adding an object to your model with
model.addAttribute("cliente", clientedao.findOne(id));
You typically want to use #GetMapping as well for your requests to populate the form. And use #PostMapping for submissions.
Aside: also take a look at Project Lombok to make your beans less error-prone and more readable. You could remove all those getters and setters and just annotate the class with #Data.
While not deprecated, you'll also want to move away from using java.util.Date and use the newer date/time classes.
I have checked so many answers here for the same but it seems nothing worked for me. I have spring security with spring mvc. when my user is trying to sign up I am sending post data to my controller. but it is giving me 405 post not supported I have disabled csrf token in security config. please let me know where did I go wrong?

Form is POST-ed to /login
action="${contextPath}/login"
but login is annotated to support only GET
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage(Model model ) {

}
maybe you should post to /signUp
My problem is very similar with this one: Spring MVC Multiple Controllers with same #RequestMapping
I'm building simple Human Resources web application with Spring Boot. I have a list of jobs and individual url for each job:
localhost:8080/jobs/1
This page contains job posting details and a form which unauthenticated users -applicants, in this case- can use to apply this job. Authenticated users -HR Manager-, can see only posting details, not the form. I have trouble with validating form inputs.
What I tried first:
#Controller
public class ApplicationController {
private final AppService appService;
#Autowired
public ApplicationController(AppService appService) {
this.appService = appService;
}
#RequestMapping(value = "/jobs/{id}", method = RequestMethod.POST)
public String handleApplyForm(#PathVariable Long id, #Valid #ModelAttribute("form") ApplyForm form, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return "job_detail"; //HTML page which contains job details and the application form
}
appService.apply(form, id);
return "redirect:/jobs";
}
#RequestMapping(value = "/applications/{id}", method = RequestMethod.GET)
public ModelAndView getApplicationPage(#PathVariable Long id) {
if (null == appService.getAppById(id)) {
throw new NoSuchElementException(String.format("Application=%s not found", id));
} else {
return new ModelAndView("application_detail", "app", appService.getAppById(id));
}
}
}
As you guess this didn't work because I couldn't get the models. So I put handleApplyForm() to JobController and changed a little bit:
#Controller
public class JobController {
private final JobService jobService;
private final AppService appService;
#Autowired
public JobController(JobService jobService, AppService appService) {
this.jobService = jobService;
this.appService = appService;
}
#RequestMapping(value = "/jobs/{id}", method = RequestMethod.POST)
public ModelAndView handleApplyForm(#PathVariable Long id, #Valid #ModelAttribute("form") ApplyForm form, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return getJobPage(id);
}
appService.apply(form, id);
return new ModelAndView("redirect:/jobs");
}
#RequestMapping(value = "/jobs/{id}", method = RequestMethod.GET)
public ModelAndView getJobPage(#PathVariable Long id) {
Map<String, Object> model = new HashMap<String, Object>();
if (null == jobService.getJobById(id)) {
throw new NoSuchElementException(String.format("Job=%s not found", id));
} else {
model.put("job", jobService.getJobById(id));
model.put("form", new ApplyForm());
}
return new ModelAndView("job_detail", model);
}
}
With this way, validations works but I still can't get the same effect here as it refreshes the page so that all valid inputs disappear and error messages don't appear.
By the way, job_detail.html is like this:
<h1>Job Details</h1>
<p th:inline="text"><strong>Title:</strong> [[${job.title}]]</p>
<p th:inline="text"><strong>Description:</strong> [[${job.description}]]</p>
<p th:inline="text"><strong>Number of people to hire:</strong> [[${job.numPeopleToHire}]]</p>
<p th:inline="text"><strong>Last application date:</strong> [[${job.lastDate}]]</p>
<div sec:authorize="isAuthenticated()">
<form th:action="#{/jobs/} + ${job.id}" method="post">
<input type="submit" value="Delete this posting" name="delete" />
</form>
</div>
<div sec:authorize="isAnonymous()">
<h1>Application Form</h1>
<form action="#" th:action="#{/jobs/} + ${job.id}" method="post">
<div>
<label>First name</label>
<input type="text" name="firstName" th:value="${form.firstName}" />
<td th:if="${#fields.hasErrors('form.firstName')}" th:errors="${form.firstName}"></td>
</div>
<!-- and other input fields -->
<input type="submit" value="Submit" name="apply" /> <input type="reset" value="Reset" />
</form>
</div>
Check thymeleaf documentation here
Values for th:field attributes must be selection expressions (*{...}),
Also ApplyForm is exposed then you can catch it in the form.
Then your form should looks like this:
<form action="#" th:action="#{/jobs/} + ${job.id}" th:object="${applyForm}" method="post">
<div>
