问题

打包遇到这个问题，本地项目启动没问题，打包出这个

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 org.junit.runners.ParentRunner.validate(ParentRunner.java:416) at org.junit.runners.ParentRunner.<init>(ParentRunner.java:84) at org.junit.runners.BlockJUnit4ClassRunner.<init>(BlockJUnit4ClassRunner.java:65) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<init>(SpringJUnit4ClassRunner.java:138) at org.springframework.test.context.junit4.SpringRunner.<init>(SpringRunner.java:49) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.junit.internal.builders.AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:104) at org.junit.internal.builders.AnnotatedBuilder.runnerForClass(AnnotatedBuilder.java:86) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59) at

原因

找到这个方法，在自己的单元测试，发现注释了单元测试，可以看出报错反复提示单元测试

解决 (No runnable methods)

先开始全部注释，发现还有这个错，然后又直接删除这个类，还是报错，最后没办法，放开了这个单元测试 然后就没这个错了，但是出现了个其他的阻碍我打包

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) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1687) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1624) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:555) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:483) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:306)

解决

参考文章Tom 还是你的单元测试加上👇

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

注意不要注释了下边的单元测试，要不还是打包失败
