我有Spring Boot应用程序版本1.5.x,它正在使用org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory,我正在尝试将其迁移到Spring Boot 2,但该应用程序无法编译,尽管它具有依赖性org.springframework.boot:spring-boot-starter-tomcat.编译器发出以下错误:

error: package org.springframework.boot.context.embedded.tomcat

测试类: -

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { WebsocketSourceConfiguration.class,
        WebSocketSourceIntegrationTests.class }, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = {
                "websocket.path=/some_websocket_path", "websocket.allowedOrigins=*",
                "spring.cloud.stream.default-binder=kafka" })
public class WebSocketSourceIntegrationTests {

    private String port = "8080";

    @Test
    public void testWebSocketStreamSource() throws IOException, InterruptedException {
        StandardWebSocketClient webSocketClient = new StandardWebSocketClient();
        ClientWebSocketContainer clientWebSocketContainer = new ClientWebSocketContainer(webSocketClient,
                "ws://localhost:" + port + "/some_websocket_path");
        clientWebSocketContainer.start();
        WebSocketSession session = clientWebSocketContainer.getSession(null);
        session.sendMessage(new TextMessage("foo"));
        System.out.println("Done****************************************************");
    }

}

我在这里看到了同样的问题,但没有任何帮助.我可以知道我错过了什么吗？

我spring-boot-starter-tomcat在依赖关系层次结构中具有编译时依赖性.

我需要在 tomcat 7 上运行我的 spring boot 2.0 应用程序

我收到这个错误
