Mule Expression to get individual object from a Json Array - mule

Question

Want to extract each object from my json payload which looks like this: Need to pass each object from this map into splitter or collection splitter. I cannot use foreach scope here.
[
{
"Name": null,
"Key": "4",
"Header": {
"Id": "14"
}
},
{
"Name": null,
"Key": "5",
"Header": {
"Id": "15"
}
}
]

Answer 1

To get the entire object from the array we can use simple #[payload] and this will take care just like for each scope.

Answer 2

If you want to parse and access the JSON elements then
**<json:json-to-object-transformer/>** is the way to do the trick.
java.util.HashMap or java.util.List or java.util.Map
depends on the type of your JSON data.
You can also use java.lang.Object

Answer 3

There are multiple ways to do this :
1) As mentioned by Vijay, use json-to-object transformer to map input json to any Collection type e.g.
<json:json-to-object-transformer returnClass="java.util.List" doc:name="JSON to Object"/>
<collection-splitter doc:name="Collection Splitter"/>
2) Use dataweave to get a Collection from input json data :
<dw:transform-message doc:name="Transform Message">
<dw:set-payload><![CDATA[%dw 1.0
%output application/java
---
payload
]]></dw:set-payload>
</dw:transform-message>
<collection-splitter doc:name="Collection Splitter"/>
