同学好，建议遇到此类问题尝试自己解决，每个人都是从不会到会的，得锻炼解决问题的能力，像这里直接看caused by 附近的异常即可

nested exception is java.io.FileNotFoundException: class path resource [com/Sys/classpath/spring/spring-dao.xml] cannot be opened because it does not exist

说得非常明白，就是spring-dao.xml这个文件找不到。。所以同学有这个文件吗？

如果有，我感觉还是跟你配置有关，请和视频对齐，可以尝试把spring-dao.xml放到src/test/resources这个文件夹下面再执行ut

  老师您好，我的src/main/resources下面有spring的xml文件，还有test/resources下也有，不知道是哪个位置的配置信息出了问题呢，还是报Failed to load ApplicationContext错误，折腾好久了

  同学好，这种错误一般可以把caused by附近的错误贴网上查找，
  Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [com/Sys/classpath/spring/spring-dao.xml]; nested exception is java.io.FileNotFoundException: class path resource [com/Sys/classpath/spring/spring-dao.xml] cannot be opened because it does not exist

  需要检查一下web.xml
  里面的com/Sys/classpath/spring/spring-dao.xml。。。 这个配置是否正确。。我感觉应该不会有这么奇怪的目录吧？com/Sys/classpath/
