I am adding server side validation in my project. and somehow the error message from controller is not reaching view page.
I am using :
spring
jpa,
JSR303 for validation, and
bootstrap
Below is code for add.jsp

user = userRepository.save(user);
return "redirect:user?id=" + user.getId();

import javax.persistence.Table;
import javax.validation.constraints.NotNull;

#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)

public String getName() {

public void setRole(Role role) {
this.role = role;
}
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
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";

any idea?
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"

I implemented the Spring Boot Spring Security for handling authentication.
But as soon as I implemented it I keep getting re-directed to the webjars js instead of the welcome page. Here is my code, please suggest what could be the problem.

I encountered the same issue. Adding
.antMatchers("webjars/**").permitAll()
to the SecurityConfiguration did the trick.
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.
