I am working on creating a Mule Anypoint connector using DevKit to connect to an internally developed API. Using the @RestCall annotation, I was able to successfully use my connector in a Mule flow, with the connector returning a String of the following JSON:
{
"name": "Bryan",
"email": "[email protected]",
"uid": "b6fr89dbf6d9156cace5f3c78dc9851d957381ef",
"email_verified": true
}
I know I could implement a "JSON to Object" transformer in the Mule flow, but I would like for the connector to return a POJO instead. That being said, I modified abstract method annotated by the @RestCall to return an Account object:
@Processor
@RestCall(
uri="https://api.myservice.com/v2/account",
method=HttpMethod.GET,
contentType = "application/json")
public abstract Account getUserInformation() throws IOException;
Just for reference, here is how I defined Account:
package org.mule.modules.myservice.model;
import java.io.Serializable;
public class Account implements Serializable {
private static final long serialVersionUID = -1L;
private String name;
private String email;
private String uid;
private boolean emailVerified;
/**
* removed getters and setters for brevity
*/
}
However, now that I am trying to return the Account object, I receive the following error:
org.mule.api.transformer.TransformerException: Could not find a transformer to transform "SimpleDataType{type=java.lang.String, mimeType='/'}" to "SimpleDataType{type=org.mule.modules.myservice.model.Account, mimeType='/'}".
I see that there is a @Transformer annotation, but documentation is lacking on how to implement this in regards to working with JSON and/or working within the context of a @RestCall within a Mule connector.
Can anyone offer up advice on how to transform a String of JSON into an Account object within the connector?
