打包 java.lang.Exception: No runnable methods或javax.websocket.server.ServerContainer not available

問題

打包遇到這個問題，本地項目啓動沒問題，打包出這個

java.lang.Exception: No runnable methods
	at org.junit.runners.BlockJUnit4ClassRunner.validateInstanceMethods(BlockJUnit4ClassRunner.java:191)
	at org.junit.runners.BlockJUnit4ClassRunner.collectInitializationErrors(BlockJUnit4ClassRunner.java:128)

	at 

原因

找到這個方法，在自己的單元測試，發現註釋了單元測試，可以看出報錯反覆提示單元測試

解決 (No runnable methods)

先開始全部註釋，發現還有這個錯，然後又直接刪除這個類，還是報錯，最後沒辦法，放開了這個單元測試
然後就沒這個錯了，但是出現了個其他的阻礙我打包

Caused by: java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available
	at org.springframework.util.Assert.state(Assert.java:70)
	at org.springframework.web.socket.server.standard.ServerEndpointExporter.afterPropertiesSet(ServerEndpointExporter.java:102)

解決

參考文章Tom
還是你的單元測試加上👇

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

注意不要註釋了下邊的單元測試，要不還是打包失敗
