Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration

• 工具：Intellij Idea\
• jdk版本：1.8
• 在SpringBoot项目中跑Junit单元测试发现此错

今天在使用test测试的时候报IllegalStateException

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

解决办法：把SpringBoot启动类放到项目包的根目录下 如下图所示： 重新启动测试后正常！
