仔细看报错内容的话，其实已经很明显，比如这几行：
[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 4.199 s <<< FAILURE! - in com.example.demo.DemoApplicationTests
[ERROR] getDData(com.example.demo.DemoApplicationTests) Time elapsed: 0.002 s <<< ERROR!

Caused by: java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available
需要在test类中加
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) 就可以了，楼主的如下：
问题完美解决。
