-----------------------------------
Summary: camel-jpa - Avoid using EntityManager from header by
default
Key: CAMEL-16501
URL: https://issues.apache.org/jira/browse/CAMEL-16501
Project: Camel
Issue Type: Improvement
Components: camel-jpa
Reporter: Claus Ibsen
Fix For: 3.x
See CAMEL-16470
Historically camel-jpa would lookup from exchange header / property an
EntityManager to use instead of from its own component. This was needed by jbpm
and other 3rd party frameworks that integrated with Camel.
However this causes pain for normal users, where you just want to use the jpa
component out of the box with the JPA EM it has been configured with. And if
you add other jpa components to integrate with other databases, then they
should out of the box use their own EM and so on. This is how JMS, Kafka and
other components work.
So to allow the old behavior, we add a boolean option on the jpa component to
turn on the old style. And then leave it off for new style onwards.
