Java SE 和焊接？

Question

我目前正在为 Java SE（焊接）测试 CDI 2.0 - 我读到，没有必要使用 beans.xml，所以我试了一下：

Hallo.class:

public class Hallo {

   public String sayHallo() {
      return "hallo";
   }
}

然后我有一个 Test.class:

@ApplicationScoped
public class Test {

@Inject Hallo hallo;

   public String sayHallo() {
      return hallo.sayHallo() + " from Test";
   }
}

我终于在这里尝试使用 CDI：

public class Demo {

public static void main(String[] args) {
    SeContainerInitializer initializer = SeContainerInitializer.newInstance();
    /** disable discovery and register classes manually */
    try (SeContainer container = initializer.disableDiscovery().addPackages(Demo.class).initialize()) {
        Test test = container.select(Test.class).get();
        test.sayHallo();
    }
}
}

不幸的是，它不起作用。我收到这条消息：

我错过了什么？

提前致谢。

Answer 1

CDI 容器工作正常。
Transactional services not available 声明您不在事务管理器下运行，默认情况下，您（几乎）在应用程序服务器中运行拥有事务管理器。
