从线程调用bean时，没有作用域类型javax.enterprise.context.RequestScoped的活动上下文

在这种情况下，Weld使用的是与线程（RequestContext）关联的未绑定RequestContext
。您需要在创建的线程中手动初始化新的RequestContext，这对我有用：

public static void main(String[] args) throws Exception {    Weld weld = new Weld();    final WeldContainer container = weld.initialize();    RequestContext requestContext= container.instance().select(RequestContext.class, UnboundLiteral.INSTANCE).get();    requestContext.activate();    final MyPojo pojo = container.instance().select(MyPojo.class).get();    Thread t = new Thread() {        public void run() { RequestContext requestContext= container.instance().select(RequestContext.class, UnboundLiteral.INSTANCE).get(); requestContext.activate(); System.out.println("1" + pojo.ping());         }    };    t.start();    t.join();    System.out.println("2" + pojo.ping());    weld.shutdown();}
