Holaaaa. Alguien pudo hacer que al momento de hacer un GET a la direccion. http://localhost:8080/v1/teacher Les salieran los cursos (course). A mi me muestra el siguiente Error: { "timestamp": "2020-03-17T21:22:58.267+0000", "status": 500, "error": "Internal Server Error", "message": "Could not write JSON: failed to lazily initialize a collection of role: com.rony.springhibernate.model.Teacher.courses, could not initialize proxy - no Session; nested exception is com.fasterxml.jackson.databind.JsonMappingException: failed to lazily initialize a collection of role: com.rony.springhibernate.model.Teacher.courses, could not initialize proxy - no Session (through reference chain: com.rony.springhibernate.model.Teacher[\"courses\"])", "path": "/v1/teacher" } Me puede alguien ayudar o compartir su codigo. ya he intentado muchas cosas y no me sale. :(

Revisa si no es por que te falta en tus modelos un @jsonignore

Anahi una consulta. Docker que papel podria jugar aqui?

Diego Forero

Team Platzi•

Tu puedes tener un contenedor que tenga la versión de java que necesitas para ejecutar tu aplicación y todas las dependencias, esto se sube usando por ejemplo kubernetes o docker swarm para poder tener varias instancias de ese contenedor. No se si en heroku se puede desplegar aplicaciones en docker pero en si es posible,

El repositorio existen varios pero el heroku al fin free

Usuario anónimo

user•

super :) gracias

Si les sale el siguiente error en el despliegue a heroku durante la ejecución del comando git push heroku master:

En mi caso es por que estaba trabajando en el pom.xml el tag de esta forma <java.version>11</java.version> si o si cambiarlo a la versión 1.8 de esta forma <java.version>1.8</java.version> y luego el push y compilación si salio exitoso:

No me lo dejo subir ni deployar me podrias ayudar con esto que pude hacer mal. Porque en mi maquina local funciona todo perfecto.

Gracias.-

Aquí el problema parece ser tu base de datos, revisa bien que los datos estén apuntando a la base de datos de heroku y que todo lo que esté mapeado corresponda con lo que este en heroku.

Leonardo Aguirre

Gracia por suerte repase el curso y verifique cada paso hasta que pude subir la APP a heroku.

Ahora estoy con el front end…
