Samply Common Mailing
This library offers utilities for building and sending HTML emails.
It provides a master template file that is used for all emails. The content and footer for emails can be set by the projects that use this library. The template engine is Google Closure Templates.
The configuration for email sending (connection to mail server etc.) can be specified in an XML file, which is parsed with the Samply Common Config library.
Usage
The configuration file for mail sending is named mailSending.xml.
You can either create a MailSending configuration object by reading the XML file or set its values in Java Code.
MailSending mailSending = MailSender.loadMailSendingConfig("myproject");
In the documentation for the Samply Common Config library you can see where the configuration file can be placed. The configuration is needed to create a MailSender instance:
MailSender mailSender = new MailSender(mailSending);
An email builder combines different template files and generates the text:
String templateFolder = mailSending.getTemplateFolder();
EmailBuilder builder = new EmailBuilder(templateFolder);
builder.addTemplateFile("Footer.soy", "Footer");
builder.addTemplateFile("TestMailContent.soy", "TestMailContent");
You can write and add template files that provide implementations for different parts of the email. This is done with Delegate Templates. There are three delegate templates, namely maincontent, footer and greeting. Setting a maincontent is mandatory, the other templates are optional. The greeting part has a default implementation, which should usually suffice.
For a complete working example please take a look at the maven test folder (src/test/).
The template files must all be located in one folder whose path must be specified in the configuration.
An OutgoingEmail object gets all information needed for writing the email:
OutgoingEmail email = new OutgoingEmail();
email.addAddressee("werner.mueller@example.com");
email.setSubject("Subject: Test");
email.putParameter("name", "Müller");
email.putParameter("title", "Prof. Dr.");
email.setLocale("de");
email.putParameter("testPar", "http://example.org");
email.setBuilder(builder);
The parameters "name" and "title" are used in the main template to generate a standard personalized greeting, depending on the locale. If no name is provided, you get an anonymous greeting. All other parameters can be set to be used by the templates.
Now, after having set the parameters and specified the templates, the mail can be sent:
mailSender.send(email);
