Hi. I'm trying to validate data in @PrePersist callback method (same pb as
http://forum.hibernate.org/viewtopic.php?t=955614&highlight=callback). Here is my entity bean Category (simplified with no getters/setters) :
Code:
@Entity
@Table(name = "t_category")
public class Category {
@Id
@GeneratedValue
private Long id;
@Column(nullable = false, length = 30)
private String name;
@Column(nullable = false)
private String description;
@OneToMany(mappedBy = "category", cascade = CascadeType.REMOVE)
@OrderBy("name ASC")
private Collection<Product> products;
@PrePersist
private void validateData() {
if (name == null || "".equals(name))
throw new ValidationException("Invalid name");
if (description == null || "".equals(description))
throw new ValidationException("Invalid description");
}
ValidationException is a RuntimeException as defined in the spec. Now, I wrote a JUnit class test that tries to persist a Category with invalid values and expects a ValidationException :
Code:
@Test
public void invalidValues() throws Exception {
Category category;
try {
category = new Category("", "");
tx.begin();
em.persist(category);
fail("Object with empty values should not be created");
} catch (ValidationException e) {
}
}
The call back method validateData is called, the transaction is rollbaked, but I do not catch a ValidationException but a RuntimeException (caused by a java.lang.reflect.InvocationTargetException). In fact, if I catch the RuntimeException and write e.getCause().getCause() I will get my ValidationException. Any idea ?
Here is the stack trace
