我有一个新的Spring Boot应用程序,我正在尝试启动它。
我收到的错误信息是:
org.springframework.context.ApplicationContextException: Unable to start reactive web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ReactiveWebApplicationContext due to missing ReactiveWebServerFactory bean.

注释中(即使它们分别带有@Configuration
和@Component
注释):@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = {FooConfig.class, FooHandler.class})
- user2337270@ComponentScan
注释也可以解决问题。 - user2337270
