我希望以这种方式注入配置参数:

public class MyManagedBean {
    @Inject
    public MyManagedBean(@Named("user") String user){
        ....

    }
}

所以我尝试用这种方式实现一个生成器方法:

@ApplicationScoped
public class MyConfiguration {
    private Properties loadProperties() {
        Properties properties = new Properties();
        try {
            properties.load(getClass().getResourceAsStream(
                    "user.properties"));
        } catch (IOException e) {
            throw new RuntimeException();
        }
        return properties;
    }

    @Produces
    @Named("user")
    String getUser() {
        return loadProperties().getProperty("user");
    }
}

我有这样定义的其他bean:

public class OtherManagedBean {
    @Inject
    public OtherManagedBean(MyManagedBean myManagedBean){
        ....

    }
}

但是,当我尝试部署它时,我遇到了这个异常:
