Package com.onec.mail.dispatch

Class HttpMailDispatcher

java.lang.Object
com.onec.mail.dispatch.HttpMailDispatcher
All Implemented Interfaces:
MailDispatcher
public class HttpMailDispatcher extends Object implements MailDispatcher
Universal provider adapter (provider=http). POSTs a rendered, provider-specific JSON body to any mail API's REST endpoint, so a new provider can be onboarded with config only — no new code.

The JSON payload is produced by the Thymeleaf template at onec.mail.http.body-template (TEXT mode). The MailMessage is exposed as msg, and json.str(x) yields a correctly-escaped, quoted JSON string. Example fragment for a SendGrid-style API: 


 {
   "from": { "email": [(${json.str(msg.from)})] },
   "subject": [(${json.str(msg.subject)})],
   "content": [ { "type": "text/html", "value": [(${json.str(msg.html)})] } ]
 }
