HelloWorld 示例

本示例演示在 Weld SE 容器中注入一个 HelloWorld Bean，以及从 Weld SE 容器中获取该 Bean 并运行相应的方法。

HelloWorld 类

import javax.inject.Singleton;

@Singleton
public class HelloWorld {
    
    public void sayHello(){
        System.out.println("Hello World");
    }
}

注入和运行该 HelloWorld Bean:

import org.jboss.weld.environment.se.Weld;
import org.jboss.weld.environment.se.WeldContainer;

public class Main {

    public static void main(String[] args) throws Exception {

        Weld weld = new Weld();
        WeldContainer container = weld.initialize();
        HelloWorld test = container.select(HelloWorld.class).get();
        test.sayHello();
        container.shutdown();
    }
}
