java – Spring启动测试失败说,由于缺少ServletWebServerFactory bean,无法启动ServletWebServerApplicationContext
作者:互联网
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****************************************************");
}
}
我见过同样的问题here,但没有任何帮助我.我可以知道我错过了什么吗?
我在依赖关系层次结构中将spring-boot-starter-tomcat作为编译时依赖项.
解决方法:
这条消息说:
您需要在ApplicationContext中配置至少1个ServletWebServerFactory bean,因此如果您已经有spring-boot-starter-tomcat,则需要自动配置该bean或手动执行.
因此,在测试中只有2个配置类来加载applicationContext,这些是= {WebsocketSourceConfiguration.class,WebSocketSourceIntegrationTests.class},那么至少在其中一个类中应该有一个@Bean方法返回所需的实例ServletWebServerFactory.
*解决方案*
确保加载配置类中的所有bean
WebsocketSourceConfiguration {
@Bean
ServletWebServerFactory servletWebServerFactory(){
return new TomcatServletWebServerFactory();
}
}
或者还使AutoConfiguration能够对这些bean进行类路径扫描和自动配置.
@EnableAutoConfiguration
WebsocketSourceConfiguration
也可以在Integration Test类中完成.
@EnableAutoConfiguration
WebSocketSourceIntegrationTests
