This java wrapper around Premailer. It is roughly based on the wrapper from here, with a few important differences
- It works
- Premailer is brought in as a dependency rather than being directly included in the source. This allows you to easily bump Premailer as a dependency
- Added a method that allows you to terminate a Premailer instance (
PremailerInterface.destroyInstance) - A fix for JDK 1.8 in regards to conflicts for
.mergemethod (see here) - The
Premailerclass no longer acts like a pseudo singleton. Its up to the user to manage the instance (typically you would store this in a Singleton to reuse thePremailerInstance) - Uses a versioning scheme to identify between Premailer releases, i.e. 1.0_1.8.7 means version 1 using Premailer 1.8.7
Currently hosted on maven central, with the following details
<dependency>
<groupId>org.mdedetrich</groupId>
<artifactId>java-premailer-wrapper</artifactId>
<version>1.1_1.8.7</version>
</dependency>If you haven't already done so, you need to add the Rubygems maven repository, i.e.
<repository>
<id>rubygems-releases</id>
<url>http://rubygems-proxy.torquebox.org/releases</url>
</repository>You can build a jar by doing
mvn compile
mvn package
To use, do something like this
String testHtml = "<html><head></head><body><p>test</p></body></html>";
// Create a Premailer
Premailer premailer = new Premailer()
// Get the instance
PremailerInterface premailerInterface = premailer.getPremailerInstance();
// Pass your options in form of HashMap
Map<String, Object> options = new HashMap<String, Object>( );
// Pass at least this option for html string
options.put( "with_html_string", true );
// Initialize premailer with html and options
premailerInterface.init( testHtml, options );
System.out.print( premailerInterface.plain_text( ) );
System.out.print( premailerInterface.inline_css( ) );
// Shut it down
premailer.destroyInstance();
