I'm trying to POST some object fields to a RestController using thymeleaf.
But the result of the post returns what looks like a parsing error :
There was an unexpected error (type=Unsupported Media Type, status=415). Content type
'application/x-www-form-urlencoded;charset=UTF-8' not supported
The index page sends two attributes to the controller which then calls the business service that builds the new object.

This is the Rest Controller :
#RestController
public class AccountController {
#Autowired
private AccountService accountService;
#RequestMapping(value="/accounts", method=RequestMethod.POST)
public void addAccount(#RequestBody Account account ) {
accountService.addAccount(account);
}
}
Account is a simple POJO :
public class Account {
private String id;
private String owner;
private double budget;
private double budgetInvest;
private double budgetFonction;
public Account() {
}
public Account(String id,String owner, double budget, double budgetInvest, double budgetFonction
) {
super();
this.id = id;
this.owner=owner;
this.budget = budget;
this.budgetInvest = budgetInvest;
this.budgetFonction = budgetFonction;
}
public Account (String owner, double budget) {
this.owner = owner;
this.budget=budget;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public double getBudget() {
return budget;
}
public void setBudget(double budget) {
this.budget = budget;
}
public double getBudgetInvest() {
return budgetInvest;
}
public void setBudgetInvest(double budgetInvest) {
this.budgetInvest = budgetInvest;
}
public double getBudgetFonction() {
return budgetFonction;
}
public void setBudgetFonction(double budgetFonction) {
this.budgetFonction = budgetFonction;
}
public String getOwner() {
return owner;
}
public void setOwner(String owner) {
this.owner = owner;
}
}
And the add method simply adds the object to a list of objects.
What am i doing wrong here ?
I think problem in you controller. First it won't be #RestController. It will be #Controller. Second it won't be #RequestBody. It will be #ModelAttribute.So write your controller like
#Controller
public class AccountController {
#Autowired
private AccountService accountService;
#RequestMapping(value="/accounts", method=RequestMethod.POST)
public void addAccount(#ModelAttribute("account") Account account ) {
System.out.ptintln("Checking");
accountService.addAccount(account);
}
The most relevant to the discussion of REST, the #RestController annota- tion tells Spring that all handler methods in the controller should have their return value written directly to the body of the response, rather than being carried in the model to a view for rendering. This line from book spring in action. So here you should use #Controller annotation.
You can use restcontroller but u must using ajax post for run "/account"

Hi I'm building a skeleton of a car renting webapp and I'm trying to create a view that shows some details like location name, car name etc.
View code- car-list.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Vehicle List</title>
<h2 th:text="${location1}">Locations</h2>
<table class="table table-stripped">
<thead>
<td th:text="${vehicle1Name}">Vehicle Name</td>
</tr>
</thead>
<td th:text="${vehicle2Name}">Vehicle Name</td>
</tr>
</table>
</head>
<body>
</body>
</html>
And heres my controller
package com.project.CS4125.controller;
import com.project.CS4125.model.*;
import com.project.CS4125.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;
#Controller
#RequestMapping("/car-list")
public class VehicleController {
#GetMapping("/car-list")
public String carList(Model model){
Vehicle VWGolf = new BasicCar();
Vehicle Duster = new SUVDecorator(new BasicCar());
Location limerick= new Location("Limerick");
model.addAttribute("location1", limerick.getLocationName());
model.addAttribute("vehicle1Name", "Volkswagen Golf");
model.addAttribute("vehicle2Name", "Dacia Duster");
return "index";
}
}
My problem is the view comes up completely empty, any help appreciated.
EDIT
Before this page I have a register and login page
index.html (register page
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">

<p>Password <input type="password" name="password"></p>
<button type="submit">Register</button>
</form>
<button>Login Here</button>

<p>Password <input type="password" name="password"></p>
<button type="submit">Login</button>
</form>
<button>Register Here</button>
</body>
</html>
And heres the controller for these
#Controller
#RequestMapping("/")
public class IndexController {
#Autowired
private UserService userService;
#Autowired
private CustomerFactory userFactory;
#PostMapping("/register")
public String registerUser(#ModelAttribute User user){
User u = userFactory.createUser(user.getName(), user.getPassword());
userService.saveUser(u);
return "login";
}
#GetMapping("/login")
public String login(){
return "login";
}
#PostMapping("/login")
public String loginUser(#ModelAttribute User user){
User authenticatedUser = userService.authenticate(user.getName(), user.getPassword());
System.out.println(authenticatedUser.toString());
return "car-list";
}
}
Even after adding the code from the answer below I'm still getting an empty page, after submitting the login form moving to the car list page its still empty.
I also noticed in the answer the URL is http://localhost:8080/car-list but when I try it its http://localhost:8080/login
I've just tested your code and you have two problems.
The first one is at your:
#Controller
#RequestMapping("/car-list")
public class VehicleController {
#GetMapping("/car-list")
In this GetMapping you're saying that you want to access your template at /car-list/car-list.
The seccond one is with your template name. You're returning "index" when you should return "car-list", at this you're returning the template name.
So, editting your code like this:
#Controller
#RequestMapping("/car-list")
public class VehicleController {
#GetMapping
public String carList(Model model){
model.addAttribute("location1", "Answer");
model.addAttribute("vehicle1Name", "Volkswagen Golf");
model.addAttribute("vehicle2Name", "Dacia Duster");
return "car-list";
}
}
I got:
Template working and returning

Hibernate validator doesn't work.
my code run properly but doesn't show any error
I am attaching file structure
following libraries are being used
hibernate version 6.0.2
spring version 5.0.6
The code looks fine. Reading your question, it seems that you might be a little confused between these two:
Hibernate ORM: Implementation of JPA
Hibernate Validator: Implementation of Bean Validation
So, for Bean Validation to work, you need to add Hibernate Validator in classpath. Means simply add it in dependencies of your build.gradle/pom.xml i.e. the build script of your build tool.
I create simple Spring app.I have two views(forma,confirmation),model(User) and Spring Bean-Controller(Main_Controller).When I'm on the adress http://localhost:8080/Path/forma.htm and fill all forma fields and submit forma glassfish say HTTP Status 400 - Bad Request.Why?To work well should I see a confirmation page with client entry.

Below is code for Controller.java

}

if (result.hasErrors()) {
return "redirect:user?add";
} else {
System.out.println("Inside postAddUser");
user = userRepository.save(user);
return "redirect:user?id=" + user.getId();
}
}
Below is code for User.java
package in.ac.jmi.entities;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;
import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.NotEmpty;
#Entity
#Table(name="USER")
public class User extends UrlEntity{
#Column(name="NAME", nullable = false)
#NotEmpty(message="Name can not be empty")
private String name;
#Column(name="ROLE", nullable = false)
#NotNull(message="Role can not be left blank")
private Role role;
#Column(name = "EMAIL_ADDRESS", nullable = false)
#NotEmpty(message="email address can not be empty")
private String emailAddress;
public User(){}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Role getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
public String getEmailAddress() {

this.emailAddress = emailAddress;
}
#Override
public String toString() {
return "\nUser [name=" + name + ", role=" + role + ", emailAddress="
+ emailAddress + "]";
}
}
The reason is you are using return "redirect:user?add";, which cleared the error messages in model, try change it to return "user?add";
