小编Sun*_*ezz的帖子

我有一个带有 Spring-Security/Session 和 Spring-Websocket 的 Spring Boot 2.2 MVC 应用程序。
它被配置为仅在经过身份验证时允许 websocket 连接。

以下是在单元测试中创建 Websocket 客户端的推荐方法。（至少我在 spring 文档中看到过这个）

private StompSession createWebsocket() throws InterruptedException, ExecutionException, TimeoutException {

    List<Transport> transports = new ArrayList<>(1);
    transports.add(new WebSocketTransport(new StandardWebSocketClient()));
    WebSocketStompClient stompClient = new WebSocketStompClient(new SockJsClient(transports));
    stompClient.setMessageConverter(new MappingJackson2MessageConverter());

    StompSession stompSession = stompClient.connect("ws://localhost:" + port + "/app",  new  StompSessionHandlerAdapter() {}).get(1, SECONDS);
    return stompSession;
}

问题

但是，这样我在日志中得到了异常，因为 Spring 重定向到登录页面，这通常是好的和需要的，因为 Websocket 请求未经身份验证。
日志确认：

2019-11-12 18:03:32.487 DEBUG 19592 --- [o-auto-1-exec-3] o.s.s.w.u.m.AndRequestMatcher            : All requestMatchers returned true
2019-11-12 18:03:32.487 DEBUG 19592 …

在我的 Spring Boot 应用程序中，我也使用了 websockets。一切正常，正如在生产中预期的那样。

现在我开始使用 Spring-Boot-Test 创建单元测试。

每次我启动 @SpringBootTest 时，都会遇到以下异常（缩短）：

java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'createWebSocketContainer' defined in class path resource [com/package/spring/ws/MyWebsocketConfig.class]: Invocation of init method failed;
Caused by: java.lang.IllegalStateException: Attribute 'javax.websocket.server.ServerContainer' not found in ServletContext
