Java Spring with Hibernate User Messages in Spring Capturing Form Validation Errors

@Valid, doesn't work with Maven

Below, I added the model and controller java classes. Once I run, I don't receive any error. If I submit the button, it saves the empty datas. It doesn't catch the errors.

package com.test.websitesi.model;

import java.util.List;

import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Lob; import javax.persistence.OneToMany; import javax.validation.constraints.NotNull;

import org.hibernate.validator.constraints.NotBlank;

@Entity public class FoodMenu {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int foodId;

@NotNull
private String name;

@NotNull
private String czDescr;
private String enDescr;
private String trDescr;

@NotNull
private int price;
private boolean isMenuOfToday;

@Lob
private byte[] bytes;
private String photoDescr;

@OneToMany
private List<ItemOrder> order;

public int getFoodId() {
    return foodId;
}
public void setFoodId(int foodId) {
    this.foodId = foodId;
}

public byte[] getBytes() {
    return bytes;
}
public void setBytes(byte[] bytes) {
    this.bytes = bytes;
}
public String getPhotoDescr() {
    return photoDescr;
}
public void setPhotoDescr(String photoDescr) {
    this.photoDescr = photoDescr;
}
public int getId() {
    return foodId;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getCzDescr() {
    return czDescr;
}
public void setCzDescr(String czDescr) {
    this.czDescr = czDescr;
}
public String getEnDescr() {
    return enDescr;
}
public void setEnDescr(String enDescr) {
    this.enDescr = enDescr;
}
public String getTrDescr() {
    return trDescr;
}
public void setTrDescr(String trDescr) {
    this.trDescr = trDescr;
}
public int getPrice() {
    return price;
}
public void setPrice(int price) {
    this.price = price;
}
public boolean isMenuOfToday() {
    return isMenuOfToday;
}
public void setMenuOfToday(boolean isMenuOfToday) {
    this.isMenuOfToday = isMenuOfToday;
}

}

package com.anatoliakebap.websitesi.controller;

@Controller public class FoodMenuController {

@Autowired
private FoodMenuService foodMenuService;

// Form for adding a new menu
@RequestMapping("/addmenuform")
public String formNewMenu (Model model){    
    model.addAttribute("foodMenu", new FoodMenu());
    return "/addmenuform";
}

//save menu and retunr listmenu
@RequestMapping(value = "/addmenuform", method=RequestMethod.POST)
public String formNewMenu (@Valid FoodMenu foodMenu, BindingResult result){

    if(result.hasErrors()){
        return "redirect:/addmenuform";
    }

    foodMenuService.save(foodMenu);
    return "redirect:/listmenu";
}


@SuppressWarnings("unchecked")
@RequestMapping("/listmenu")
public String listAllMenu (Model model){

    List<FoodMenu> foodMenues = foodMenuService.findAll() ;

    model.addAttribute("foodMenues", foodMenues);

    return "/listmenu";
}

I had the same problem.

After I added this dependency, it worked:

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
</dependency>

And with Gradle I had to add: compile group: 'org.hibernate', name: 'hibernate-validator', version: '6.1.2.Final' in my dependencies for the @Valid to work
