[SOLVED]Cant specify fastjson when marshal

[senayuki]

I trying to use fastjson instance of jackson, with camel-k 1.8.1, so I wrote this yaml

apiVersion: camel.apache.org/v1
kind: Integration
metadata:
  name: jackson-test
  namespace: camel
spec:
  dependencies:
  - mvn:mysql:mysql-connector-java:8.0.28
  - mvn:org.apache.commons:commons-dbcp2:2.8.0
  - mvn:com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.13.2
  flows:
  - from:
      steps:
      - to:
          uri: freemarker:sql.ftl?contentCache=false
      - to:
          uri: (hidden bean)
      - marshal:
        json: 
           library: fastjson
      uri: rest:get:/

And I got this error in container
java.lang.IllegalArgumentException: Unexpected type: class org.apache.camel.model.dataformat.JsonDataFormat

I'm very confused. Why doesn't the "library" usage I found in the unit test of the source code work.
In addition, I think the yaml file of camel-k also puzzles me when I refer to the java example of camel. I don't know how to convert them accurately.

It should be:

      - marshal:
          json:
            library: Fastjson

your indentation seems to be wrong

[oscerd]

It's a different way of writing routes through YAML, so there no automatic conversion, for the moment, from plain camel or Java DSL, to YAML.

Also Jackson is a thing, Fastjson is another thing.

Ow ow ow ow, I did make an indentation mistake. I was stupid! Thanks for your help!
The Jackson dependency is that I forgot to remove it when I was testing at the beginning, which is not a problem

My suggestion is to use jitpack while developing.
