There are many problems in spring boot unit test. When I use websocket, I will run the test class and report an error: error creating bean with name ‘serverendpoint exporter’ defined in class path resource [COM/Jacklin/config]/ WebSocketConfig.class ]Here I introduce the annotation @ serverendpoint:
There are two ways to solve this problem
Method 1: remove the @ runwith of the test class（ SpringRunner.class ）, but this method will have limitations. For example, when you want a @ authwired class below, you will report an error. I can’t do it here, according to your code situation.
The second way: add webenvironment after springboottest= SpringBootTest.WebEnvironment.RANDOM_ Port means to create a web application context (response based or servlet based). Reason: websocket depends on the startup of Tomcat and other containers. So in the process of testing, we need to really start a Tomcat as a container.
Run after adding, no more error!!
