Groovy Project with Persistence JPA

Este ejemplo es desarrollado con Groovy Lang con persistencia de datos de JPA.

Ejemplo

En este ejemplo, una persona es creada y consultada más tarde.

Código de ejemplo

Entidad

Cree una clase Persona con la anotación @Entidad.

En la clase, cree la propiedad name de tipo String. En la clase, cree la propiedad id del tipo long.

El identificador de la entidad Persona es la propiedad id con la anotación @Id.

Para generar automáticamente el secuencial, agregue la anotación @GeneratedValue.

Unresolved directive in <stdin> - include::src/main/groovy/org/superbiz/groovy/Person.groovy[]

Persistencia

En la persistencia se agrega la entidad Persona con <class> org.superbiz.groovy.Person </class>

Unresolved directive in <stdin> - include::src/main/resources/META-INF/persistence.xml[]

Ejecutando el ejemplo

Ejecutar el ejemplo es bastante simple. En el directorio /tomee/examples/groovy-jpa ejecute:

$ mvn clean install

Lo que debería crear un resultado como el siguiente:
