What is the replacement of setDataFormatResolver for ExtendedCamelContext?

Question

With Apache Camel on 3.20 version I used to use the setDataFormatResolver method, which was from ExtendedCamelContext, to set a custom data format in CamelContext. But since 4.0.0-M3 version, this method has been removed from the class. I'm wondering, how could I replace this method to some similar? I searched at the documentation, but I didn't find the answer I'm looking for.

Another question about the same subject, now that ExtendedCamelContext is decoupled from CamelContext, when ExtendedCamelContext is instantiated the CamelContext will keep being one single instance?

Answer 1

To set a specific DataFormatResolver in Camel 4, you need to call the method ExtendedCamelContext.html#addContextPlugin.

So assuming that the name of your custom class is CustomDataFormatResolver, the code would look like the following code snippet:

context.getCamelContextExtension().addContextPlugin(
    DataFormatResolver.class, new CustomDataFormatResolver()
);

Where context is your Camel context instance.

Yes there is only one ExtendedCamelContext per CamelContext.
