可能会有所帮助,请参阅这个答案,感谢 Andres Cespedes Morales

May be this can help, refer to this answer, thanks to Andres Cespedes Morales:

这条消息说明:你需要在ApplicationContext中配置至少1个ServletWebServerFactory bean ,所以如果你已经有了spring-boot-starter-tomcat,你需要自动配置该bean或手动执行trong>。

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.

因此,在测试中只有2个配置类来加载applicationContext,这些是= {WebsocketSourceConfiguration.class,WebSocketSourceIntegrationTests.class},然后至少在其中一个类中,应该有一个@Bean方法返回所需ServletWebServerFactory的实例。

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 *

确保加载配置类中的所有bean

Make sure to load all the beans within your configuration class

WebsocketSourceConfiguration {
  @Bean 
  ServletWebServerFactory servletWebServerFactory(){
  return new TomcatServletWebServerFactory();
  }
}

或者还启用自动配置进行类路径扫描和自动配置这些bean。

OR also enable the AutoConfiguration to do a classpath scanning and auto-configuration of those beans.

@EnableAutoConfiguration
WebsocketSourceConfiguration

也可以在Integration Test类中完成。

Can be done also at the Integration Test class.

@EnableAutoConfiguration
WebSocketSourceIntegrationTests
