How to unmarshal JSON to multiple items with JBoss Fuse (camel)?

Question

I currently have the following simplified JSON (test.json):

{"type":"monkey","food":"banana"},{"type":"dog","food":"bone"},{"type":"cat","food":"fish"}

Doing the following:

from("file:/tmp/input").routeId("test")
                        .unmarshal().json(JsonLibrary.Jackson)
                        .log("After unmarshall:\n ${body}");

When dropping the JSON file into the input folder, I only get the following map:

{type=monkey, food=banana}

How to get all items into the mapping?

Answer 1

If you want to get all then put them to an array like

[{"type":"monkey","food":"banana"},{"type":"dog","food":"bone"},{"type":"cat","food":"fish"}]

Then setup dataFormat with useList option true. In Xml DSL that i tried is

<dataFormats>
  <json id="json" library="Jackson"  useList="true"/>
</dataFormats>

In Java is

JacksonDataFormat json = new JacksonDataFormat(); 
json.useList();

Then use unmarshall with the preceding data format

XML DSL:

<unmarshal ref="json"/>

So you should have :

from("file:/tmp/input").routeId("test")
                        .unmarshal().json(json)
                        .log("After unmarshall:\n ${body}");

And the output is a list:

 [{type=monkey, food=banana}, {type=dog, food=bone}, {type=cat, food=fish}]
