Test Class:-
@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****************************************************");
}
}
I have seen same issue here but nothing helped me. May I know what I'm missing ?
I have spring-boot-starter-tomcat as compile time dependency in the dependency Hierarchy.
This message says: You need to configure at least 1 ServletWebServerFactory bean in the ApplicationContext, so if you already have spring-boot-starter-tomcat you need to either autoconfigure that bean or to do it manually.
So, in the test there are only 2 configuration classes to load the applicationContext, these are = { WebsocketSourceConfiguration.class, WebSocketSourceIntegrationTests.class }, then at least in one of these classes there should be a @Bean method returning an instance of the desired ServletWebServerFactory.
* SOLUTION *
Make sure to load all the beans within your configuration class
WebsocketSourceConfiguration {
@Bean
ServletWebServerFactory servletWebServerFactory(){
return new TomcatServletWebServerFactory();
}
}
OR also enable the AutoConfiguration to do a classpath scanning and auto-configuration of those beans.
@EnableAutoConfiguration
WebsocketSourceConfiguration
Can be done also at the Integration Test class.
@EnableAutoConfiguration
WebSocketSourceIntegrationTests
