My registration of my custom Entity Doesn't work

My registration of my custom Entity Doesn't work - java

Hello I have problem with registrating an Entity which i Made.I use Spring.I have made my Model and Everything but i get an error when i try to registrate an Event in my site.
here is an image of the Error:
and Here is an image of all of my folders
I firstly had problems with connections OneToMany and ManyToOne but i searched here and repaired them.But now i don't have errors in the console. Only in the browser. Here is my code in Event entity
package com.example.app.entity;
import javax.persistence.*;
import java.util.List;
#Entity
#Table (name = "events")
public class Event {

private List<String> games;
#ManyToMany(fetch=FetchType.EAGER,cascade = {CascadeType.ALL})

private List<User> players;
private double latitude;
private double longitude;
private String description;
private String date;
private User owner;
private String gamesToParse;
private String usersToParse;
public String getGamesToParse() {
return gamesToParse;
}
public void setGamesToParse(String gamesToParse) {
this.gamesToParse = gamesToParse;
}
public String getUsersToParse() {
return usersToParse;
}
public void setUsersToParse(String usersToParse) {

public void setPlayers(List<User> players) {

i think the mistake is that when i pass arguments in my html something fails so i will show my html too

here is my controller too
package com.example.app.Controllers;
import com.example.app.Service.EventService;
import com.example.app.model.RegistrationEvent;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
#Controller
public class EventsController {
#Autowired
private EventService eventService;
#GetMapping("/user/eventsAndPeople/registerEvent")
public String getRegisterPage(Model model, RegistrationEvent registrationEvent){
model.addAttribute("event", registrationEvent);
return "events/registerEvent";
}
#PostMapping("/user/eventsAndPeople/registerEvent")
public String registerEvent(#Valid #ModelAttribute RegistrationEvent registrationEvent){
this.eventService.register(registrationEvent);
return "events/registerEvent";
}
#RequestMapping(value = "/user/eventsAndPeople", method = RequestMethod.GET)
public String getEventsAndPeoplePage(){
return "home/eventsAndPeople";
}
}
I use Xampp for local server and HeidiSQL so i can track my database.
I'm very confused what's wrong. Oh and something i forgot here is my EventService Implementation:
import com.example.app.Repository.EventRepository;
import com.example.app.Repository.UserRepository;
import com.example.app.Service.EventService;
import com.example.app.entity.Event;
import com.example.app.model.RegistrationEvent;
import org.modelmapper.ModelMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Service;
#Service
public class EventServiceImpl implements EventService {
#Autowired
private UserRepository userRepository;
#Autowired
private EventRepository eventRepository;
#Autowired
private ModelMapper modelMapper;
public EventServiceImpl() {
super();
}
#Override
public void register(RegistrationEvent registrationEvent) {
Authentication auth =
SecurityContextHolder.getContext().getAuthentication();
String name = auth.getName();
Event event = this.modelMapper.map(registrationEvent, Event.class);
event.setGames(registrationEvent.getGamesToParse());
event.setDescription(registrationEvent.getDescription());
event.setLatitude(registrationEvent.getLatitude());
event.setLongitude(registrationEvent.getLongitude());
event.setName(registrationEvent.getName());
event.setPlayers(registrationEvent.getPlayers());
event.setDate(registrationEvent.getDate());
event.setOwner(this.userRepository.findOneByUsername(name));
this.eventRepository.save(event);
}
}

Try declaring your methods like this:
public String getRegisterPage(RegistrationEvent registrationEvent, BindingResult bindingResult, Model model)
{
model.addAttribute("event", registrationEvent);
return "events/registerEvent";
}
public String registerEvent(#Valid #ModelAttribute RegistrationEvent registrationEvent, BindingResult bindingResult, Model model){
this.eventService.register(registrationEvent);
return "events/registerEvent";
}
EDIT:
You are returning "events/registerEvent" on both methods. Is that correct?

public Orders() {
}
public Orders(int id) {
this.id = id;
}
public int getId() {
return id;

}
public String getDescription() {

}
public void setDescription(String description) {
this.description = description;
}
public boolean isSold() {
return sold;
}
public void setSold(boolean sold) {
this.sold = sold;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public String getBody() {
return body;
}
public void setBody(String body) {
this.body = body;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public String getEngine() {
return engine;
}
public void setEngine(String engine) {
this.engine = engine;
}
public String getModel() {
return model;

public void setModel(String model) {
this.model = model;
}
public byte[] getImage() {
return image;
}
public void setImage(byte[] image) {
this.image = image;
}
public String getImageStr() {
return imageStr;
}
public void setImageStr(String imageStr) {
this.imageStr = imageStr;
} }

So you can do something like this
<img src="data:image/png;base64,${order.getImage()}">

How can I use two seperate Forms using spring and thymeleaf?

I am trying to pass in every form different objects and to different entities.
It is actually works, I can see the new added values(rows) in my database, but still I keep getting the same Exception by submitting both forms separately.

Is the controller ok? Error parsing one template meanwhile the others work fine

I'm working on an exercise that simulates a store but when printing on screen the option to add products doesn't work. Print a whitelabel error:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Sat Mar 30 17:09:05 CET 2019
There was an unexpected error (type=Internal Server Error, status=500).
An error happened during template parsing (template: "class path resource [templates/producto.html]")
I tried to improve the references in the model and changed the name to some parameters but the same error kept coming up.
This is the controller.
#Controller
public class ProductController {
#Autowired
ProductService productService;
#GetMapping (value = "/addProduct")
public String addProduct (Model model) {
model.addAttribute("producto", new Product ());
return "producto";
}
#GetMapping (value = "/deleteProduct")
public String deleteProduct (Model model, #RequestParam Integer idProduct) {
productService.deleteProduct(idProduct);
return "redirect:/list-productos";
}
#GetMapping (value = "/updateProduct")
public String updateProduct (Model model, #RequestParam Integer idProduct) {
Product producto = productService.getProductById(idProduct);
model.addAttribute("producto", producto);
return "producto";
}
#PostMapping (value = "/addProduct")
public String addProduct (Model model, String nombre, String descripcion, String marca, float precio) {
productService.addProduct(nombre, descripcion, marca, precio);
return "redirect:/list-productos";
}
#PostMapping (value = "/updateProduct")
public String updateProduct (Model model, Product producto) {
productService.updateProduct(producto);
return "redirect:/list-productos";
}
}
This is the service.
public interface ProductService {
List<Product> getAll();
Product getProductById(Integer idProduct);
void addProduct(String nombre, String descripcion, String marca, float precio);
void addProduct(Product product);
void updateProduct(Product product);
void deleteProduct(Integer idProduct);
}
This is the implementation.
#Service
public class ProductServiceImpl implements ProductService {
#Autowired
ProductRepository productRepository;
#Override
public List<Product> getAll() {
return productRepository.findAll();
}
#Override
public void addProduct(String nombre, String descripcion, String marca, float precio) {
Product producto = new Product(nombre, descripcion, marca, precio);
productRepository.save(producto);
}
#Override
public void addProduct(Product product) {
productRepository.save(product);
}
#Override
public void updateProduct(Product product) {
productRepository.save(product);
}
#Override
public void deleteProduct(Integer idProduct) {
Optional<Product> producto = productRepository.findById(idProduct);
if (producto.isPresent()) {
productRepository.deleteById(idProduct);
}
}
#Override
public Product getProductById(Integer id) {
return productRepository.getOne(id);
}
}
This is the model
#Entity
#Table (name = "product")
public class Product {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column (name = "idProduct")
private Integer idProduct;
#Column (name = "nombre")
private String nombre;
#Column (name = "descripcion")
private String descripcion;
#Column (name = "marca")
private String marca;
#Column (name = "precio")
private float precio;
#OneToMany(mappedBy = "producto")
private Set<OrderLine> orderLines;
public Product() {
}
public Product(String nombre, String descripcion, String marca, float precio) {
super();
this.nombre = nombre;
this.descripcion = descripcion;
this.marca = marca;
this.precio = precio;
}
public Integer getIdProduct() {
return idProduct;
}
public void setId(Integer idProduct) {
this.idProduct = idProduct;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public String getDescripcion() {
return descripcion;
}
public void setDescripcion(String descripcion) {
this.descripcion = descripcion;
}
public String getMarca() {
return marca;
}
public void setMarca(String marca) {
this.marca = marca;
}
public float getPrecio() {
return precio;
}
public void setPrecio(float precio) {
this.precio = precio;
}
}
This is the form in HTML.
<form th:action="#{/addProduct}" th:object="${producto}"
method="post">
<div class="form-group">
<label for="nombre" class="control-label">Nombre</label> <input
id="nombre" class="form-control" th:field="*{nombre}" />
</div>
<div class="form-group">
<label for="descripcion" class="control-label">Descripción</label>
<input id="descripcion" class="form-control"
th:field="*{descripcion}" />
</div>
<div class="form-group">
<label for="marca" class="control-label">Marca</label> <input
id="marca" class="form-control" th:field="*{marca}" />
</div>
<div class="form-group">
<label for="precio" class="control-label">Precio</label> <input
id="precio" class="form-control" th:field="*{precio}" />
</div>
<div class="form-group">
<button type="submit" class="btn btn-success">Añadir
producto</button>
</div>
</form>

Yeah controller is bad in updateProduct. Instead of:
model.addAttribute("producto", producto);
Write:
model.addAttribute("producto1", producto);
Because in thymeleaf you referenced it in th:object as producto1 not as producto.

Passing multiple instances of a bean created under c:forEach in JSF

I have a JSF form, in which we need to select list of products(using checkbox). The products are displayed using the c:forEach iteration. I am storing the detail of each selected product in a spearate bean called BuyProduct.java. I want each of this selected bean/product to be passed to the action attribute of form. Or is there any alternate way to implement this?

Thymeleaf not able to post collections / lists of objects

I'm creating a web-application with spring MVC, hibernate and thymeleaf.
I have a page where I can manage users, on this page you should be able to place and remove users from groups.
I am doing this with 2 multiple select boxes.
I added a jquery script what handles the movement of users from the one select box to the other one.
But when i submit, my Group.users object list is empty and I do not get any exceptions.
Does anyone has some advice?
Thanks in advance.
Edit
I just discovered that all thymeleaf attributes inside the html tag "option", aren't compiled. Except for the th:each attr.
So it's pretty clear the problem is in my thymeleaf file.
Thymeleaf / edit.html:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"

<title>Edit group</title>
</head>
<body>
<script>
$(document).ready(function() {
$(".clickable").click(function() {
if ($(this).hasClass("selected")) {
$(this).removeClass("selected").addClass("unselected");
$('#userGroupContainer').append(this);
$("option:selected").css("background-color", "red");
} else {
$(this).removeClass("unselected").addClass("selected");
$('#userGroupContainerSelected').append(this);
$("option:selected").css("background-color", "green");
}
