springboot整合websocket,测试类启动报错,
解决方式:在注解中加上webEnvironment参数,此参数的含义,参看官方文档
You can use the webEnvironment attribute of @SpringBootTest to further refine how your tests will run:
MOCK — Loads a WebApplicationContext and provides a mock servlet environment. Embedded servlet containers are not started when using this annotation. If servlet APIs are not on your classpath this mode will transparently fallback to creating a regular non-web ApplicationContext. Can be used in conjunction with @AutoConfigureMockMvc for MockMvc-based testing of your application.
RANDOM_PORT — Loads an ServletWebServerApplicationContext and provides a real servlet environment. Embedded servlet containers are started and listening on a random port.
DEFINED_PORT — Loads an ServletWebServerApplicationContext and provides a real servlet environment. Embedded servlet containers are started and listening on a defined port (i.e from your application.properties or on the default port 8080).
NONE — Loads an ApplicationContext using SpringApplication but does not provide any servlet environment (mock or otherwise).
有4个value可选,根据需要选择即可,其实就是给你的测试类配置了一个真实的servlet环境,并且给这个启动的嵌入式servlet容器一个端口进行监听;
如此就可以结果websocket无法获取的问题
@SpringBootTest(classes = XXX.class,webEnvironment = SpringBootTest.WebEnvironment.RANDOM_POR
