Hi,
The "json" and "outJson" variables you mentioned will *not* resolve to the
same Java object (because of Camel Injector being invoked here behind the
scenes while resolving), well almost always ... depending if e.g. an object
under the name "json-jackson" is already bound to the Camel registery which
isn't really typical. The following code snippet should make both cases
clear to you:
CamelContext context = new DefaultCamelContext();
DataFormat first = context.resolveDataFormat("json-jackson");
DataFormat second = context.resolveDataFormat("json-jackson");
System.out.println(first != second); // true
JndiRegistry registry = new JndiRegistry();
registry.bind("json-jackson", new
org.apache.camel.component.jackson.JacksonDataFormat());
((DefaultCamelContext) context).setRegistry(registry);
DataFormat third = context.resolveDataFormat("json-jackson");
DataFormat fourth = context.resolveDataFormat("json-jackson");
System.out.println(third == fourth); // true
System.out.println(third != first); // true
System.out.println(fourth != first); // true
If interested, looking into the different implementations of Camel’s
DataFormatResolver should clarify this to you, specially the
DefaultDataFormatResolver one.
