--------------------------------------
Summary: support JSONPath on beans as well as Strings &
InputStreams
Key: CAMEL-10646
URL: https://issues.apache.org/jira/browse/CAMEL-10646
Project: Camel
Issue Type: Improvement
Reporter: james strachan
it'd be nice if we could use json path expressions on beans too; so that if
some JSON gets unmarshalled via jackson we could still use jsonPath on the
object.
Here's a possible implementation approach (though maybe there's a more optimal
approach?)

Maybe this code
https://github.com/apache/camel/blob/master/components/camel-jsonpath/src/main/java/org/apache/camel/jsonpath/JsonPathEngine.java#L114
should check if the body can't be converted to a File, String or InputStream
it tries to convert the payload to something like JSonPathNavigator (a new
interface we create). If it can be converted we use that interface to transform
the payload.
Then we could have decoupled ways to convert objects into navigable formats
(e.g. Maps / Lists)?
e.g.
{code:java}
public JacksonJsonPathNavigator implements JSonPathNavigator {
public Object convert(Object input) {
ObjectMapper mapper = new ObjectMapper();
return mapper.convertValue(input, Map.class);
}
}
{code}
