-----------------------------------------

             Summary: Adding ability to look up objects using EntityManager.find in JPA component.
                 Key: CAMEL-7550
                 URL: https://issues.apache.org/jira/browse/CAMEL-7550
             Project: Camel
          Issue Type: Wish
          Components: camel-jpa
            Reporter: Knut-Håvard Aksnes
            Priority: Minor


Currently Camel-JPA offers 3 different ways of looking up objects

# Using Query
# Using NativeQuery
# Using NamedQuery

I would like a fourth: Using EntityManager.find

EntityManager.find is simple to use and in many situations far more efficient out of the box
than the other options, at least when using Hibernate. This is due to the fact that it uses
the caches by default.
The find method requires two arguments, one of them the key is natural to provide as incoming
body, the second, the class of the object wanted is natural to have as a route parameter and/or
header.
