= Apache DeltaSpike I18n Demo
This example shows how to use DeltaSpike I18n.
== Intro of Apache DeltaSpike I18n
The Apache DeltaSpike I18n is a module of Apache DeltaSpike project that enables the use of type-safe messages and internationalization.
== Code sample
=== @MessageBundle interface
Create an interface with a method for each type-safe message. The interface should be annotated with `@MessageBundle` and for each message it is needed to annotaated with `@MessageTemplate`:
public interface MessageHelper {
String openejbAndDeltaspike();
=== MessageHelper property file
It will lookup for the string "openejb.and.deltaspike" (without the curly brackets "{}") in a property file with the same name of the interface but with the extension .properties instead of .java or .class.
openejb.and.deltaspike = OpenEJB and DeltaSpike are cool products!
=== Using the type safe messages
Now you can inject the interface and retrieve the type-safe message:
private MessageHelper msg;
public void check() {
assertEquals("OpenEJB and DeltaSpike are cool products!", msg.openejbAndDeltaspike());
== Running
Running the example is fairly simple. In the `/tomee/examples/deltaspike-i18n` directory
$ mvn clean install
Which should create output like the following.
