JPA Validation Strategy

Question

NetBeans allows me to choose between three values ​​for the JPA validation strategy: Auto, Callback, and None. What does "Auto" mean? “Callback” means using @PrePersist, @PreUpdate and @PreRemove?

Is performance a hit if I use Auto or Callback if there is no check to execute?

Answer 1

The JPA 2.0 specification (JSR 317) does not require the implementation of Bean Validation (JSR-303). Validation is optional. Thus, it javax.persistence.ValidationModecan take different values:

• Auto ( ) - ,
• Callback - PersistenceException,
• None - ,
