Vaadin service interfaces as a CDI bean

Some Vaadin service interfaces can be implemented as a CDI bean. This way there is no need to register your implementation in the framework, and it became a managed bean with CDI features. Interfaces looked up by the add-on:

• I18NProvider

• Instantiator

• SystemMessagesProvider

• ErrorHandler

Beans have to be qualified by @VaadinServiceEnabled to be picked up.

Example of a SystemMessagesProvider:

Java

@VaadinServiceEnabled
@VaadinServiceScoped
public class TestSystemMessagesProvider implements SystemMessagesProvider {
    @Override
    public SystemMessages getSystemMessages(SystemMessagesInfo systemMessagesInfo) {
        CustomizedSystemMessages messages = new CustomizedSystemMessages();
        messages.setInternalErrorMessage("Sorry, something went wrong :(");
        return messages;
    }
}
