---------------------------------------
Summary: camel-jpa: Single result
Key: CAMEL-19327
URL: https://issues.apache.org/jira/browse/CAMEL-19327
Project: Camel
Issue Type: Improvement
Components: camel-jpa
Affects Versions: 4.0-M3, 3.20.4
Reporter: Jacek Szymański
A common use case is that a query (or a find) should return exactly one object,
and any other result is to be considered an error. camel-sql supports the
outputType=SelectOne option which will cause the component to throw an
exception if the query does not return a single row. camel-jpa does not have
such an option and thus user must manually check for body size.
This PR addresses that. It adds a boolean option {{singleResult}}, which, if
set to true:
- in case of a query will cause the component to put the single fetched object
into the message body, not in a List, or throw an exception otherwise
- in case of a find, if no object is found the component will throw an
exception rather than put null into the body
it has no effect on updates, and doesn't alter the consumer.
