insert into database with anypoint studio

Question

I would like to save the flow coming from this json file: https://gist.githubusercontent.com/Rajeun/3dbbe8ca240d479dbabe/raw/aba5d0ec9345b886426ab767376b7c9cb60c251f/person.json in a database using anypoint studio.

For this i'm using a http connector where i mentioned the link of the json file. and then i used a json-to-object transformer and a database connector. In my db i have a table with id, token, tel "int" and email is a varchar -(I tested the connection and its working well). when i run my code:

Answer 1

Remove the empty template query:

<db:template-query name="Template_Query" doc:name="Template Query">
   <db:parameterized-query />
</db:template-query>

Also, does 'myclass' exist? if not try just using a map:

<json:json-to-object-transformer returnClass="java.util.HashMap" doc:name="JSON to Object"/>

Also It looks like you want to retrieve that JSON file from the specified URL. For that you want the http:request not http:listener. http:listener is used as a message source waiting for requests to your app.

You should use the http:request to request the file and trigger it using a polling message source:

<http:request-config name="HTTP_Request_Configuration" host="www.gist.githubusercontent.com" port="80" doc:name="HTTP Request Configuration"/>


 <flow name="testFlow">
    <poll>
        <http:request config-ref="HTTP_Request_Configuration" path="Rajeun/3dbbe8ca240d479dbabe/raw/aba5d0ec9345b886426ab767376b7c9cb60c251f/person.json" method="GET" doc:name="HTTP"/>
    </poll>

</flow>
