Minnal Jpa has useful abstractions for your DAL. It makes use of ActiveJpa, a java library that attempts to implement the active record pattern on top of JPA. It eliminates the need to create DAO or Repository classes and make programming DAL a lot more simpler. Minnal recommends using JPA for DB access and provides a JPA plugin module with ActiveJpa integration.
Minnal Jpa provides a base domain class org.minnal.jpa.entity.BaseDomain which extends the ActiveJpa model class. Extending the base domain enables you to do ActiveRecord style operations like, Person.find(1L);, Person.where("firstName", "Ganesh"); etc...
1 2 3 4 5 6 | package com.example.domain;
@Entity
public class Example extends BaseDomain {
}
|
Minnal Jpa provides a plugin org.minnal.jpa.JPAPlugin to configure JPA. You just need to register the plugin to your application
1 2 3 4 5 6 7 | public class ExampleApplication extends Application<ExampleConfiguration> {
@Override
protected void registerPlugins() {
registerPlugin(new JPAPlugin());
}
}
|
The JPAPlugin reads the database configuration from your application configuration and loads the EntityManagerFactory. You can configure the vendor specific properties in the db configuration section.
