Bootstrap CDI 2.0 in Java SE

Abstract

This is a quick reference for bootstrapping CDI 2.0 in a Java SE application.

CDI 2.0 (JSR 365)

Maven Dependency

<dependency>
    <groupId>org.jboss.weld.se</groupId>
    <artifactId>weld-se-core</artifactId>
    <version>3.0.2.Final</version>
</dependency>

beans.xml

File location is /META-INF/beans.xml. This file is optional, though I’ve found it’s still good to have.

<beans version="2.0" 
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
     http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_2_0.xsd" 
    bean-discovery-mode="all"
>
    <scan>
        <exclude name="org.jboss.weld.**" />
    </scan>  
</beans>

Java SE Application

package org.ferris.cdi.example.main;

import javax.enterprise.inject.se.SeContainer;
import javax.enterprise.inject.se.SeContainerInitializer;

/**
 * The main() method for this application
 *
 * @author <a href="mailto:mjremijan@yahoo.com">Mike Remijan</a>
 */
public class Main {
    public static void main(String[] args) {

        SeContainer container
            = SeContainerInitializer.newInstance().initialize();

        Main main
            = container.select(Main.class).get();

        //. . .
    }
}

Summary

That’s it…enjoy!
