Grails template for email

In Grails, you can use the Email class from the grails-plugin-mail plugin to send emails. Here is an example of a Grails template for an email:

Email.groovy

import grails.plugin.mail.MailMessage

class Email {
    String to
    String subject
    String body

    def send() {
        MailMessage mail = new MailMessage()
        mail.to = to
        mail.subject = subject
        mail.body = body
        mail.send()
    }
}

This template defines a Email class with three properties: to, subject, and body. The send() method uses the MailMessage class from the grails-plugin-mail plugin to send the email.

Usage

To use this template, you can create an instance of the Email class and set its properties:

def email = new Email(to: '[email protected]', subject: 'Hello', body: 'This is a test email')
email.send()

You can also use the Email class as a service, injecting it into your controllers or services:

class MyController {
    def emailService

    def index() {
        def email = new Email(to: '[email protected]', subject: 'Hello', body: 'This is a test email')
        emailService.sendEmail(email)
    }
}

Configuring the email plugin

To use the Email class, you need to configure the grails-plugin-mail plugin in your Config.groovy file:

grails {
    mail {
        host = 'smtp.example.com'
        port = 587
        username = 'your-email-username'
        password = 'your-email-password'
        props = ['mail.smtp.auth': 'true']
    }
}

This configuration sets up the email plugin to use a SMTP server with the specified host, port, username, and password.

Additional features

The Email class can be extended to include additional features, such as:

Attachments: You can add attachments to the email by creating a File object and setting its name and bytes properties.
HTML content: You can set the body property to a string containing HTML content.
CC and BCC recipients: You can add CC and BCC recipients by setting the cc and bcc properties.

For example:

def email = new Email(to: '[email protected]', subject: 'Hello', body: '<html>This is a test email</html>')
email.cc = ['[email protected]']
email.bcc = ['[email protected]']
email.attachments = [new File('path/to/attachment.txt')]
email.send()
