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
package com.bolsadeideasspringboot.app.models.entity;

this.email = email;
}
public Date getCreateAt() {
return createAt;
}
public void setCreateAt(Date createAt) {
this.createAt = createAt;
}
}
this is the controller method
#RequestMapping(value="/form/{id}")
public String editar(#ModelAttribute("form") #PathVariable(value="id")Long id, Map<String, Object>model) {
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 am using spring boot+thymeleaf+neo4j. Everything is working fine except that thymeleaf is not able to resolve a few of the attributes of the 'product' variable used in the th:each block in the template product_grid.html, which includes th:src="${product.URL}", th:text="${Product.title}" and the th:action="#{/product/(${Product.getId()})}" expression in form tag. The th:text="${Product.Price}" is working. When I check the code produced in the browser the src tag is empty (src:""), the text attribute containing the title tag is not shown in the browser. The th:action works fine but when I click the button defined inside the form, the url changes to http://localhost:8080/product/?btn=View+Product
instead of the following code which is shown in the browser console
http://localhost:8080/product/?1
Note: I am trying to get the image url from a field which is stored in neo4j database. The project directory is:
project directory image

Welcome to SO.
Include setX methods for your variables in the Product class. Thymeleaf needs these to bind.
IMO, a great way to do this is to use Project Lombok and simply annotate your class with #Data. Then you won't even need to specify getters or setters (or your toString()) at all.
Use lower-case for your variables since by convention variables with a capital first letter refers to the class, not an instance variable.
As mentioned, use POST instead of GET in your form since you are submitting data.
Use the shorthand #GetMapping and #PostMapping to make it easier to read.
In this jsp, I have used 2 form actions, one to save the role(table:defining role), and other to call the drop list from other table(table: solutionList).
After clicking on submit, it is not doing anything.
If i remove this form(solutionMaster.html)
Im getting this error " Invalid property 'sMName' of bean class [com.mode;.definingrole]: Bean property 'sMName' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?.
Yes, I know the reason, Because the column 'sMName' was not the part of defining role table. what to do with this.
The Thing i want to know is,
Can we create form inside form?
2.Without creating another form, How can i get the column values of other table to defining role table?
Please help.
Thanks in advance.!!!

You are trying to populate list inside form under the tag of form. Which is wrong approach. You won't get the value from /solutionlist.html by your form. You have to call at least a GET if you want to use /solutionlist.html controller.
If i think So then you have to do the following
You don't need the '/solutionlist.html' controller.
Just bind the ArrayList solutionList into model in the controller method where the form page served. I mean the GET method of Controller where the given form is served.
ArrayList<String> solutionList=TemplateService.getSolutionListForTemplate();
model.put("solutionList", solutionList);
You will get that solutionList directly to your form as value. So, modify the select part of your form as follows
<select name="solutions"path="Solutions">
<c:forEach items="${solutionList}" var="solution">
<option value="${solution}">${solution}</option>
</c:forEach>
</select>
I have checked so many answers here for the same but it seems nothing worked for me.

Here's my MainController
package org.pkb.springlogin.controller;
import java.security.Principal;
import org.pkb.springlogin.manager.SignUpHandler;
import org.pkb.springlogin.model.SignUpInfo;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class MainController {
#Autowired
SignUpHandler signupHandler;
private static final Logger logger =LoggerFactory.getLogger(MainController.class);
#RequestMapping(value = { "/", "/welcome" }, method = RequestMethod.GET)
public String welcomePage(Model model) {
model.addAttribute("title", "Welcome");
model.addAttribute("message", "Hello friend!");
return "welcomePage";
}
#RequestMapping(value = "/admin", method = RequestMethod.GET)
public String adminPage(Model model) {
return "adminPage";
}
#RequestMapping(value="/signUp",method=RequestMethod.POST)
public String userLogin(#ModelAttribute("userForm") SignUpInfo user,ModelMap model){
System.out.println(user);
Integer id=signupHandler.process(user);
if(id!=null){
logger.debug("ID in controller:"+id);
return "success";
}
logger.error("error in controller");
return "Failure";
}
#RequestMapping(value="/signUp",method=RequestMethod.GET)
public String register(Model model){
SignUpInfo user=new SignUpInfo();
model.addAttribute("userForm", user);
return "signUp";
}
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage(Model model ) {
return "loginPage";
}
#RequestMapping(value = "/logoutSuccessful", method = RequestMethod.GET)
public String logoutSuccessfulPage(Model model) {
model.addAttribute("title", "Logout");
return "logoutSuccessfulPage";
}
#RequestMapping(value = "/userInfo", method = RequestMethod.GET)
public String userInfo(Model model, Principal principal) {
// After user login successfully.
String userName = principal.getName();
System.out.println("User Name: "+ userName);
return "userInfoPage";
}
#RequestMapping(value = "/403", method = RequestMethod.GET)
public String accessDenied(Model model, Principal principal) {
if (principal != null) {
model.addAttribute("message", "Hi " + principal.getName()
+ "<br> You do not have permission to access this page!");
} else {
model.addAttribute("msg",
"You do not have permission to access this page!");
}
return "403Page";
}
}
Here's my signUpInfo
package org.pkb.springlogin.model;
public class SignUpInfo {
private String userName;
private String password;
private String confirmPassword;
private Type type;
private Byte enabled;
public Byte getEnabled() {
return enabled;
}
public void setEnabled(Byte enabled) {
this.enabled = enabled;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getConfirmPassword() {
return confirmPassword;
}
public void setConfirmPassword(String confirmPassword) {
this.confirmPassword = confirmPassword;
}
public Type getType() {
return type;
}
public void setType(Type type) {
this.type = type;
}
#Override
public String toString() {
return "SignUpInfo [userName=" + userName + ", password=" + password + ", confirmPassword=" + confirmPassword
+ ", type=" + type + "]";
}
}
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 ) {
return "loginPage";
}
maybe you should post to /signUp
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;
}
}

Take a look at the following tutorial: A guide to forms in Spring MVC. There are some helpful hints like #ModelAttribute.
I'm trying to perform a simple validation in my view, I know that the jsf it is very simple to do more in the spring mvc is giving me a headache ...
Can anyone help me with this validation? see what I'm doing wrong ??

in my controller is validating usually more in view does not show anything how can I solve?
I am quite some time on stackoverflow, most can not find the solution ...
Your view is not showing anything as you have not included the error messages in your template. Here is an example below.
<td th:if="${#fields.hasErrors('age')}" th:errors="*{age}">Name Error</td>
