  • A proper way for JPA entities instantiation
  • creating the entities I would like to focus in this post
  • JPA2.0 entities
  • ...31 more annotations...
  • UserService
  • UserDao
  • FacebookWS
  • User u
  • UserService uses UserDAO and FacebookWS
  • but don’t know how those dependencies are instantiated
  • And you shouldn’t really care, all that is important is that UserService depends on dao and webservice object.
  • BDD template given-when-then) tests are easy to read
  • @Entity
  • public class User
  • calling new User(“someName”,”somePassowrd”, “someOtherName”, “someOtherPassword”) becomes hardly readable and maintainable
  • code duplication
  • Maintaining this code would turn into a nightmare in no time
  • running the code above will throw an exception by the JPA provider,
  • since not-nullable password field was never set.
  • Joshua Blooch gives fine example of builder pattern.
  • Instead of making the desired object directly, the client calls a constructor (or static factory) with all of the required parameters and gets a builder object. Then the client calls setter-like methods on the builder object to set each optional parameter of interest. Finally, the client calls a parameterless build method to generate the object, which is immutable. The builder is a static member class of the class it builds.
  • Coffee
  • public static class Builder
  • Builder(CoffeeType type, int cupSize)
  • Builder withMilk()
  • Coffee build()
  • Coffee(this)
  • private Coffee(Builder builder)
  • Coffee coffee = new Coffee.Builder(CoffeeType.Expresso, 3).withMilk().build();2}
  • especially if most of those parameters are optional.
  • For all entity attributes I create private fields
  • those that are obligatory become parameters for the public constructor
  • parameter-less constructor, I create one, but I give him
  • protected access level
  • protected

cdi spring comparison

shared by kuni katsuya on 11 May 12 - No Cached
  • CDI 1.0 vs. Spring 3.1 feature comparsion: bean definition & dependency injection
  • Spring offers three different approaches to do dependency injection: XML-based, annotation-based and pure Java-based (programmatic)
  • CDI on the other hand is strictly annotation-based
  • ...2 more annotations...
  • pure feature oriented-perspective
  • only little critical difference in the two technologies

jpa events auditing

shared by kuni katsuya on 23 May 12 - No Cached
  • Auditing Entities With JPA Events
  • An alternative is if you are using a generic DAO class to handle entity persistence is to put the enhanced populateTimestamp method on there and call it prior to inserting or updating the entity in the DAO
