Spring Boot EMail Service

A reusable mailer service to send emails.

<dependency>
    <groupId>it.aboutbits.springboot</groupId>
    <artifactId>emailservice</artifactId>
    <version>x.x.x</version>

This step is optional.

Usage

Sending an Email

Use the ManageEmail service to schedule an email.

Example

// @formatter:off
public void sendMail(final String to,final String subject,final String htmlBody,final String plainTextBody) {
        manageEmail.schedule(
                EmailParameter.builder()
                        .scheduleAt(OffsetDateTime.now())
                        .email(EmailParameter.Email.builder()
                                .fromName(fromName)
                                .fromAddress(fromAddress)
                                .recipient(to)
                                .subject(subject)
                                .textBody(plainTextBody)
                                .htmlBody(htmlBody)
                                .build())
                        .build()
        );
}
// @formatter:on 

Querying Emails

To read email datasets from the database use this class: QueryEmail.java

Reporting callback

If you want to receive a report after each run of the scheduler, create a Bean implementing EmailSchedulerCallback.java

Configuration

To enable this service just add @EnableEmailService to your main class. You must also enable @EnableScheduling to allow the email queue to be processed.

@SpringBootApplication
@EnableEmailService
@EnableScheduling
public class App {
    public static void main(final String[] args) {
        SpringApplication.run(App.class, args);
    }
}

The following configuration options are available:

Name	Default	Description
lib.emailservice.migrations.enabled	true	Enables database migrations.
lib.emailservice.scheduling.enabled	true	Enables the scheduler sending the emails.
lib.emailservice.scheduling.interval	30000	Specifies the milliseconds delay between runs of the scheduler.

Building and releasing a new version:
