The form show correctly, but when i submit, I get a HTTP Status 400 exception, with the description:
description The request sent by the client was syntactically incorrect ()..
I have read that it would be caused by requestparams, but i not using them.
Here is my controller:

model.addAttribute("expedientes", expedientes);
return "expediente";
}
#RequestMapping(value = "nuevo-expediente")
public String createExpedienteGet(Model model) {
model.addAttribute("expediente", new Expediente());
List<TipoExpediente> tiposExpediente = service.getTiposExpedientes();
// List<String> canales = service.getCanales();
model.addAttribute("expedientes", tiposExpediente);

return "nuevo-expediente";
}

Some help?
Thanks
I have resolve this issue. The problem was with the controller method mapping to the url.
I modified the function createExpedientePost to:
public String createExpedientePost(#ModelAttribute("expediente") Expediente expediente, BindingResult result) {
The change was the addition of BindingResult as an argument.
I hope this may help others.
It seems somebody can get such error status, when arguments for a controller method were set incorrectly.
For instance I had the same because of wrong name of referer header(It was called as referrer)
public String foo(#RequestHeader(value = "referer") final String referer) {}

Error shown is Bean property 'emergencyComplaint.emergencyComplaint' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
The getters and setters have the same return type, still it is showing this error.

This is a valid error. Take a close look at your Entity and your modelAttribute. There is no such thing emergencyComplaint.emergencyComplaint.
So, instead of:
<form:input type="text" name="emergencyComplaint" id="emergencyComplaint" path="emergencyComplaint.emergencyComplaint" />
Try this:
<form:input type="text" name="emergencyComplaint" id="emergencyComplaint" path="emergencyComplaint" />
I do not have OneToMany example handy but I think you are smart enough to identify the issue by now while reading this. If not then to get an idea, take a look at this and this.
I need to update my category object
my model:
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;

import javax.validation.constraints.NotNull;
#Entity
public class Category {
#Id
#GeneratedValue
private int id;

}
public Long getCreated() {
return created;
}
public void setCreated(Long created) {
this.created = created;
}
public Long getUpdated() {
return updated;
}
public void setUpdated(Long updated) {
this.updated = updated;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
Here my controller:
#Controller
public class CategoryController {
private CategoryRepository categoryRepository;
private static Logger logger = LogManager.getLogger(CategoryController.class);
// If class has only one constructore then #Autowired wiil execute automatically
public CategoryController(CategoryRepository categoryRepository) {
this.categoryRepository = categoryRepository;
createStubCategoryList();
}
#PostMapping(value = "/category")
public String submitCategory(Category category, Model model) {
logger.info("updateCategory = " + category);
model.addAttribute("submitted", true);
model.addAttribute("category", category);
categoryRepository.save(category);
return "category";
}
#RequestMapping("category/edit/{id}")
public String editCategory(#PathVariable("id") int id, Model model) {
Optional<Category> category = categoryRepository.findById(id);
logger.info("find_category = " + category);
model.addAttribute("category", category);
return "category";
}
Here my template to edit category:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title th:text="${appName}">Category template title</title>
<link th:href="#{/public/style.css}" rel="stylesheet"/>
<meta charset="UTF-8"/>
</head>
<body>
<div class="container">
<form method="post" action="#" th:object="${category}" th:action="#{/category}">
<h3>Category</h3>
<input type="text" placeholder="name" id="name" th:field="*{name}"/>
<textarea placeholder="Description of the category" rows="5" id="description"
th:field="*{description}"></textarea>
<input type="submit" value="Submit"/>
</form>
<div class="result_message" th:if="${submitted}">
<h3>Your category has been submitted.</h3>
<p>Find all categories here</p>
</div>
</div>
</body>
</html>
When call method in log has:
[INFO ] 2020-01-07 19:38:07.493 [http-nio-8090-exec-8] CategoryController - find_category = Optional[
Category{id=2, name='Electronics', created=1578418669105, updated=null, description='Electronics's description'}]
and here screen:
As you can see the field created=1578418669105
Nice.
Now I edit name "Electronics" to "Electronics2" and click submit.
As result call method: submitCategory in my controller. Nice.
Here result in log:
[INFO ] 2020-01-07 19:40:23.327 [http-nio-8090-exec-2] CategoryController - updateCategory =
Category{id=0, name='Electronics2', created=null, updated=null, description='Electronics's description'}
but as you can see the field created is null. Why?
I need to update only editable fields: name and description.
Another fields (like created, updated, id) must not change. This fields are not mapped.
How I can do this?
Because created, updated, id you need to pass as hidden. It is not available in html page.
Each column should be changed to updatable to false because by default is true.
#Column(name = "created", updatable = false)
private Long created;
Program is executing Select query is also running in console but not displaying on page,please check the program and correct me thank you

Just tried to set this up by creating a sample list as shown below.
#RequestMapping("/ProductList")
public String ListProducts(Model theModel)
{
List<Product> theProducts = productDAO.getAllProduct();
Product product = new Product(1,"pro-1","man-1",10,"pro-1 desc");
theProducts.add(product);
product = new Product(2,"pro-2","man-2",10,"pro-2 desc");
theProducts.add(product);
product = new Product(3,"pro-3","man-3",10,"pro-3 desc");
theProducts.add(product);
product = new Product(4,"pro-4","man-4",10,"pro-4 desc");
theProducts.add(product);
product = new Product(5,"pro-5","man-5",10,"pro-5 desc");
theProducts.add(product);
theModel.addAttribute("products",theProducts);
return "productlist";
}
The JSP page productlist.jsp is as is. No changes done. I get the output as below.
You can perhaps try putting up debug statements to see if the theProducts is correctly populated.
I'm writing simple integration tests for my app using the Spring MVC Test framework. I have two basic test cases:
The Add link form is filled in correctly (the URL and optional description input fields are entered) and a link is added to a database via POST and then the client is redirected to the /link URL.
The Add link form is empty, so the /links/create view is rendered and form errors from BindingResult are presented.
The testAddLink() test passes successfully, but the problem occurs with the testAddEmptyLink() test method.
In this test, the 'links/create' view should be rendered and I should get a 200 status code once the expression
result.hasErrors()
is true.
However, I'm getting a 302 response, which should be sent when there are no errors in the form (the URL has been set correctly)
It seems the test method testAddEmptyLink() cannot deal with form errors with BindingResult.
Do you have any ideas what could be the cause it cannot deal with form errors?
Thanks in advance.

c:forEach throws javax.el.PropertyNotFoundException: Property 'foo' not found on type java.lang.String

Closed 7 years ago.
I'm getting the error above.
What i'm trying to do is write an app that takes in an unknown number of names, then prints them out on a new page. This is supposed to be for a bowling scoring app, but for now I just want to get a list of names. The idea is for each name to go into a player object, then in turn be stored in the players arraylist. If anyone can help, I would appreciate it.
This is my controller code:
package multiplayergame;
import java.util.ArrayList;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;
#Controller
#SessionAttributes
public class MultiplayerController {
int score;
int roll;
Game game = new Game();
GameProperties gameProps = new GameProperties();
int playerNo = 0;
ArrayList<PlayerGame> players = new ArrayList<>();
PlayerGame player;
#RequestMapping(value = "/home", method = RequestMethod.GET)
public ModelAndView home() {
return new ModelAndView("home", "command", gameProps);
}
#RequestMapping(value = "/nextName", method = { RequestMethod.POST, RequestMethod.GET})
public ModelAndView homeNext(MContact mcontact, BindingResult result) {
player = new PlayerGame();
player.setName(mcontact.getName());
players.add(player);
gameProps.setPlayers(players);
playerNo++;
return new ModelAndView("home", "command", gameProps);
}
#RequestMapping(value = "/test", method = RequestMethod.POST)
public ModelAndView playNext(GameProperties gameProps2, ModelMap model) {
model.addAttribute("players", gameProps.getPlayers());
model.addAttribute("name", gameProps.getPlayers().get(playerNo).getName());
return new ModelAndView("test", "players", gameProps2);
}
}
This holds details for each player:
package multiplayergame;
public class PlayerGame {
private int score;
private int pins;
private String name;
private int roll;
private int nOfPlayers;
private int playerNo;
Game game = new Game();
public Game getGame() {
return game;
}
public void setGame(Game game) {
this.game = game;
}
public int getScore() {
return score;
}
public void setScore(int score) {
this.score = score;
}
public int getPins() {
return pins;
}
public void setPins(int pins) {
this.pins = pins;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getRoll() {
return roll;
}
public void setRoll(int roll) {
this.roll = roll;
}
public int getnOfPlayers() {
return nOfPlayers;
}
public void setnOfPlayers(int nOfPlayers) {
this.nOfPlayers = nOfPlayers;
}
public int getPlayerNo() {
return playerNo;
}
public void setPlayerNo(int playerNo) {
this.playerNo = playerNo;
}
}
This is the code for all Game properties, such as scoring etc.
package multiplayergame;
import java.util.ArrayList;
public class GameProperties {
private int score;
private int pins;
private String name;
private int roll;
private int nOfPlayers;
PlayerGame player;
private ArrayList<PlayerGame> players;
private int playerNo;
public int getScore() {
return score;
}
public void setScore(int score) {
this.score = score;
}
public int getPins() {
return pins;
}
public void setPins(int pins) {
this.pins = pins;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getRoll() {
return roll;
}
public void setRoll(int roll) {
this.roll = roll;
}
public int getnOfPlayers() {
return nOfPlayers;
}
public void setnOfPlayers(int nOfPlayers) {
this.nOfPlayers = nOfPlayers;
}
public ArrayList<PlayerGame> getPlayers() {
return players;
}
public void setPlayers(ArrayList<PlayerGame> players) {
this.players = players;
}
public int getPlayerNo() {
return playerNo;
}
public void setPlayerNo(int playerNo) {
this.playerNo = playerNo;
}
}

Change this <c:forEach var="player" items="players"> to <c:forEach var="player" items="${players}">
As your referring "players" string. it is trying to find the property name in string.
