Mail Supplier

This module provides a File supplier that can be reused and composed in other applications. The Supplier uses the mail IMAP and POP3 support from Spring Integration. The mailSupplier bean is implemented as a java.util.function.Supplier. This supplier gives you a reactive stream of emails from the provided url (imap or pop3). The supplier has a signature of Supplier<Flux<Message<?>>>. Users have to subscribe to this Flux and receive the data.

Beans for injection

You can import the MailSupplierConfiguration in the application and then inject the following bean.

mailSupplier

You need to inject this as Supplier<Flux<Message<?>>>.

You can use mailSupplier as a qualifier when injecting.

Once injected, you can use the get method of the Supplier to invoke it and then subscribe to the returned Flux.
