我正在为我的
@ServerEndpoint
编写一些集成测试，在最终让端点运行之后，我现在在
@OnOpen
中得到一个空指针，因为注入失败

我已经在github上上传了代码：

端点的定义如下所示：

@ServerEndpoint("/test")
public class MyEndpoint{

    @Inject
    private SessionHandler sessionHandler;

    @OnOpen
    public void open(Session session) {
        sessionHandler.addSession(session);//sessionhandler is @Singleton
    }

    @OnClose
    public void close(Session session) {
    }

    @OnError
    public void onError(Throwable error) {
    }

    @OnMessage
    public void handleMessage(String payload, Session session) {
    }
}

@Singleton
public class SessionHandler {
    public void addSession(Session session){}

}

@ClientEndpoint
public class SocketClient {

    @OnOpen
    public void onOpen(Session session) {
    }

    @OnMessage
    public void onMessage(String message, Session session) {
    }

    @OnClose
    public void onClose(Session session, CloseReason closeReason) {
        LOGGER.info(String.format("Session %s close because of %s",     session.getId(), closeReason));
    }

    public SocketClient openConnection(URL url) {//URL injected arquillian resource, where url is for http connection..
        WebSocketContainer container = ContainerProvider.getWebSocketContainer();
        try {
            SocketClient  client = new SocketClient();
            URI uri = URI.create(url.toString().replace("http", "ws") + "test");
            container.connectToServer(client, uri);
            return client;
        } catch (DeploymentException | IOException ex) {
            LOGGER.log(Level.SEVERE, null, ex);
            throw new RuntimeException(ex);
        }
    }

    public void closeConnection() {
        try {
            session.close(new CloseReason(CloseReason.CloseCodes.NORMAL_CLOSURE, "Client requested close"));
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

我的测试是用spock编写的，安装失败

您在可部署war中打包了SessionHandler，但显示了GameSessionHandler。你可以编辑你的帖子来反映你所拥有的吗？很抱歉，现在已经修复了，我认为所有需要复制的代码都在帖子中提供了。你仍然显示一个没有定义的GameSessionHandler类型。无论如何，我建议查看tom ee/open webbeans组件生成的日志，以查看bean（即SessionHandler）是否由于某种原因（例如，档案中没有引用的类）而未以静默方式加载。如果需要，您可以使用自定义日志记录。您是否尝试向文件
arquillian.xml
中添加一行
？这只会使容器无法启动，添加
javax.servlet:javax.servlet api
依赖项并不能修复它。。
