Spring 3 MVC validation BindingResult doesn't contain any errors
- by Travelsized
I'm attempting to get a Spring 3.0.2 WebMVC project running with the new annotated validation support. I have a Hibernate entity annotated like this:
@Entity
@Table(name = "client")
public class Client implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@Column(name = "clientId", nullable = false)
@NotEmpty
private Integer clientId;
@Basic(optional = false)
@Column(name = "firstname", nullable = false, length = 45)
@NotEmpty
@Size(min=2, max=45)
private String firstname;
... more fields, getters and setters
}
I've turned on mvc annotation support in my applicationContext.xml file:
<mvc:annotation-driven />
And I have a method in my controller that responds to a form submission:
@RequestMapping(value="/addClient.htm")
public String addClient(@ModelAttribute("client") @Valid Client client, BindingResult result) {
if(result.hasErrors()) {
return "addClient";
}
service.storeClient(client);
return "clientResult";
}
When my app loads in the server, I can see in the server log file that it loads a validator:
15 [http-8084-2] INFO org.hibernate.validator.util.Version - Hibernate Validator 4.0.2.GA
The problem I'm having is that the validator doesn't seem to kick in. I turned on the debugger, and when I get into the controller method, the BindingResult contains 0 errors after I submit an empty form. (The BindingResult does show that it contains the Client object as a target.) It then proceeds to insert a record without an Id and throws an exception. If I fill out an Id but leave the name blank, it creates a record with the Id and empty fields.
What steps am I missing to get the validation working?
