我正在尝试在我的项目中使用Apache Tamaya和CDI扩展。
我在pom.xml中包含了以下库
<dependency>
<groupId>org.apache.tamaya</groupId>
<artifactId>tamaya-core</artifactId>
<version>0.2-incubating</version>
</dependency>
<dependency>
<groupId>org.apache.tamaya.ext</groupId>
<artifactId>tamaya-cdi</artifactId>
<version>0.2-incubating</version>
</dependency>
我定义了一个扩展BasePropertySource的应用程序范围的bean。
@ApplicationScoped
public class DatabasePropertySource extends BasePropertySource {
...
}
我正在使用WildFly 10.启动应用程序时，我收到以下异常：BeanAttributes.getTypes() may not return an empty set org.apache.tamaya.integration.cdi.ConfigurationExtension$ConverterBean

即使没有自定义DatabasePropertySource，服务器也无法启动。
提前感谢任何帮助。
