I have User class So I created UserValidator.java using Validator interface of Spring for validation of User while registration.
Problem is that validations are applied successfully but jsp page does not show the error messages.
UserValidator.java
#Component
public class UserValidator implements Validator {
public boolean supports(Class<?> clazz) {
return User.class.equals(clazz);
}
public void validate(Object obj, Errors errors) {
ValidationUtils.rejectIfEmpty(errors, "userName", "Enter a valid name");
ValidationUtils.rejectIfEmpty(errors, "address", " Enter Address");
ValidationUtils.rejectIfEmpty(errors, "mobNo", "Enter valid mobile number");
ValidationUtils.rejectIfEmpty(errors, "emailId", "Enter a valid email");
User user = (User) obj;
System.out.println(""+user.getUserName());
Pattern pattern = Pattern.compile("^[A-Z0-9._%+-]+#[A-Z0-9.-]+\\.[A-Z]{2,6}$",
Pattern.CASE_INSENSITIVE);
if (!(pattern.matcher(user.getEmailId()).matches())) {
errors.rejectValue("emailId", "Invalid email! Please enter valid email");
}
}}
RegistrationController.java
#Controller
public class RegistrationController {
#Autowired
UserValidator userValidator;

webDataBinder.setValidator(userValidator);

if(userSess!=null) {

}
user.setMobNo(user.getMobNo());

I'm making a simple blog using springframework. I'm trying to make Categories for my posts/articles. When I create articles, I have the option to choose a Category and it works fine. However, when I try to edit an Article, the drop-down menu for choosing a Category is not working. It's just and empty field with a 'down arrow' sidebad and nothing happens when I click on it
//ARTICLE EDIT--------------------------------------------------
#GetMapping("/article/edit/{id}")
#PreAuthorize("isAuthenticated()")
public String edit(#PathVariable Integer id, Model model)
{
if(!this.articleRepository.exists(id))
{
return "redirect:/";
}
Article article = this.articleRepository.findOne(id);
if(!isUserAuthorOrAdmin(article))
{
return "redirect:/article/"+id;
}
List<Category> categories = this.categoryRepository.findAll();
String tagString = article.getTags().stream().map(Tag::getName).collect(Collectors.joining(", "));
model.addAttribute("view", "article/edit");
model.addAttribute("article", article);
model.addAttribute("category", categories);
model.addAttribute("tags", tagString);
return "base-layout";
}
#PostMapping("/article/edit/{id}")
#PreAuthorize("isAuthenticated()")
public String editProcess(#PathVariable Integer id, ArticleBindingModel articleBindingModel)
{
if(!this.articleRepository.exists(id))
{
return "redirect:/";
}
Article article = this.articleRepository.findOne(id);
Category category = this.categoryRepository.findOne(articleBindingModel.getCategoryId());
HashSet<Tag> tags = this.findTagsFromString(articleBindingModel.getTagString());
if(!isUserAuthorOrAdmin(article))
{
return "redirect:/article/"+id;
}
article.setContent(articleBindingModel.getContent());
article.setTitle(articleBindingModel.getTitle());
article.setCategory(category);
article.setTags(tags);
this.articleRepository.saveAndFlush(article);
return "redirect:/article/" + article.getId();
}
The html file is:
<main>
<div class="container body-content span=8 offset=2">

You should use model attributes' names inside ${}. There is a mismatch between model.addAttribute("category", categories); and th:each="category : ${categories}".
Change model attribute name to "categories" and it should be fine
model.addAttribute("categories", categories);
#PostMapping(value=("/addMessage"))
public String addMessagePostPicture(#RequestParam("picture") MultipartFile picture, Map<String, Object> model, HttpServletRequest request, #ModelAttribute MessageForm message) {
String[] contacts = request.getParameterValues("contacts");
if(message.getContacts() == null){
System.out.println("yes");
message.setContact(contacts);
}
public class MessageForm {
private String[] contacts;
public String[] getContacts() {
return contacts;
}
public void setContact(String[] contacts) {
this.contacts = contacts;
}
}
Why is message.getContacts value null? Request parameter with name contacts excisting.
addMessage.html code part where is getting that contacts parameter value
<form id="addMessageForm" class="form-horizontal" method="post" action="addMessage" enctype="multipart/form-data">
<div class="form-group ">
<label class="control-label col-sm-3 requiredField" for="contacts"> Kontaktid

I need to bind an object with a list of objects as an attribute. It is a static list and it is created and partially filled in the Controller. It is displayed correctly in the view, however the value in the input field is not set when the form is sent to the controller. I did some research and found several similar questions, however none of the proposed solutions worked for me.
edit.jsp
<c:forEach items="${priceConfigurationForm.priceList}" var="price" varStatus="priceStatus">
<tr>
<td>
<spring:bind path="priceConfigurationForm.priceList[${priceStatus.index}].country">
${price.country}
<input type="hidden" name="<c:out value="${status.expression}"/>"
id="<c:out value="${status.expression}"/>"
value="<c:out value="${status.value}"/>"/>
</spring:bind>
</td>
<td>
<spring:bind path="priceConfigurationForm.priceList[${priceStatus.index}].amount">
<input type="text" name="price" value="${price.amount}"/>
<input type="hidden"
name="<c:out value="${status.expression}"/>"
id="<c:out value="${status.expression}"/>"
value="<c:out value="${status.value}"/>"/>
</spring:bind>
</td>
<td>
<spring:bind path="priceConfigurationForm.priceList[${priceStatus.index}].currency">
${price.currency}
<input type="hidden" name="<c:out value="${status.expression}"/>"
id="<c:out value="${status.expression}"/>"
value="<c:out value="${status.value}"/>"/>
</spring:bind>
</td>
</tr>
</c:forEach>
Abstract from Controller populating the list:
#RequestMapping(value = "/price/create", method = RequestMethod.GET)
public String toCreatePriceConfiguratioView(Model model) {
log.info("::createPriceConfiguration: {}");
final PriceConfigurationForm priceConfigurationForm = new PriceConfigurationForm();

Here is my code.When I check checkbox and click the edit button the value is fetched correctly.But edited value is not updated in mysql database as well as table.I'm using jdbc template for this example."location" field is select option value.
controller get the checkbox value and fetch data from database.after that the updated value is not shown in the table.
HomeController.java
#RequestMapping("/edit")
public String update(Model model,#RequestParam Map<String,String> req){
updateValue = new Integer(req.get("checkId"));
List<Users> users = userdao.getUpdateRecord(updateValue);
model.addAttribute("result",users);
return "formedit";
}
#RequestMapping("/saveUpdate")
public String saveUpdate(Model model,#RequestParam Map<String,String> req){
String name,storage,location,address;
name = req.get("name");
storage=req.get("storage");
location=req.get("location");
address = req.get("address");
int row = userdao.updateRecord(updateValue,name,storage,location,address);
String message = row+ "updated";
model.addAttribute("message", message);
result(model);
return "home";
}
UsersDAO doesn't get the update value from formedit page.
UsersDAO.java
public List<Users> getUpdateRecord(int updateValue){
System.out.println("update value"+updateValue);
String sql="select id,name,storage,location,address from customer where id="+updateValue;
return jdbc.query(sql,new UsersMapper());
}
public int updateRecord(int id,String name,String storage,String location,String address){
return jdbc.update("update customer set name = ?,storage = ?,location = ?,address=? where id = ?",id,name,storage,location,address);
formedit.jsp
<form role="form" action="saveUpdate" method="post" class="form-horizontal">
<c:forEach var="row" items="${result}">
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label class="control-label col-xs-4 text">Customer Name</label>
<div class="col-xs-8">
<input type="text" class="form-control" name="name" value=${row.name }>
</div>
</div>
<div class="form-group">
<label class="control-label col-xs-4 text">Storage Location*</label>
<div class="col-xs-8">
<input type="text" class="form-control" name="storage" value=${row.storage }>
</div>
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label class="control-label col-xs-4 text">Location</label>
<div class="col-xs-8">
<input type="text" class="form-control" name="location" value=${row.location }>
</div>
</div>
<div class="form-group">
<label class="control-label col-xs-4 text">Customer Address</label>
<div class="col-xs-8">
<textarea class="form-control" name="address">${row.address }</textarea>
</div>
</div>
</div>
<input type="submit" class="btn btn-success btn-md col-md-offset-6" value="Update">
</div>
</c:forEach>
</form>
}
Because this is wrong:
return jdbc.update("update customer set name = ?,storage = ?,location = ?,address=? where id = ?",id,name,storage,location,address);
The parameters order is incorrect, it doesnt find id with value address.
I have a jsp page in which i have used spring form tag so that i can use model attribute and bind data to it. It was working fine on submit the form but after adding enctype="multipart/form-data" model attributes are returing null to the controller. What is wrong here ?

On its own, DispatcherServlet doesn't know how to handle multipart form data; that's why we require multipart resolver.
You should register it in your servlet-config:
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="500000" />
</bean>
Use CommonsMultipartFile or MultipartFile instead of File in your User object:
private CommonsMultipartFile imageFile;
You can try this code to save file:
File imageFileSave = new File(Constants.MEDIA_FILE_PATH);
FileUtils.writeByteArrayToFile(imageFileSave , imageFile.getBytes());
