When trying to run tests using command mvn test I receive an error:

我正在使用 junit 4.12 并希望一次忽略类中的所有测试用例，而不是在每个标记为测试的方法之前添加忽略注释。根据文档，可以在类级别添加@Ignore。

@Ignore
public class BasicOperationsTest extends TestBaseClass{

我像上面那样做但它不起作用 - 所有测试方法都被执行。当我在 @Test 方法之前添加 ignore 在这种情况下注释起作用并且不执行测试。

最后，我的 websocket 客户端连接到端点，但我无法提取消息有效负载。我可以获得标头，但无法识别有效载荷。

我的 WebSocket 客户端如下所示：

    WebSocketTransport webSocketTransport = new WebSocketTransport(standardWebSocketClient);
    SockJsClient sockJsClient = new SockJsClient(Arrays.asList(webSocketTransport));
    WebSocketStompClient stompClient = new WebSocketStompClient(sockJsClient);

    stompClient.setMessageConverter(new StringMessageConverter());

    StompSessionHandler sessionHandler = new MyStompSessionHandler();
    ListenableFuture<StompSession> connect = stompClient.connect(URL, sessionHandler);

        StompSession stompSession = connect.get();
        System.out.println("sessionId: " + stompSession.getSessionId());

        String path = "/queue/orders";

        stompSession.subscribe(path, new MySimpleStompFrameHandler());

Stomp 帧处理程序：

    private class MySimpleStompFrameHandler implements StompFrameHandler {

    @Override
    public Type getPayloadType(StompHeaders stompHeaders) {
        System.out.println("Headers " + stompHeaders.toString());
        return String.class;
    }

    @Override
    public void handleFrame(StompHeaders stompHeaders, Object payload) {
        System.out.println("Msg " + …

我需要编写websocket客户端。我开始遵循此教程：https : //github.com/eugenp/tutorials/blob/master/spring-boot/src/main/java/org/baeldung/websocket

在运行StomClient之后，我收到：

    java.lang.NoClassDefFoundError: javax/websocket/ClientEndpointConfig$Configurator

Run Code Online (Sandbox Code Playgroud)

在WebSocketTester.testConnection（WebSocketTester.java:16）

原因：java.lang.ClassNotFoundException：javax.websocket.ClientEndpointConfig $ Configurator at java.net.URLClassLoader.findClass（URLClassLoader.java:381）at java.lang.ClassLoader.loadClass（ClassLoader.java:424）at sun.misc .Launcher $ AppClassLoader.loadClass（Launcher.java:335）at java.lang.ClassLoader.loadClass（ClassLoader.java:357）...另外23个

我的pom仅具有以下依赖性：

    <dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-websocket</artifactId>
        <version>5.0.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-messaging</artifactId>
        <version>5.0.2.RELEASE</version>
    </dependency>

客户端和会话处理程序是从github下附加链接复制的。WebSocketClient client = new StandardWebSocketClient();客户端类中的这一行引发异常
