当然后来由于自己一直项目运行一直报“ org.thingsboard.server.dao.exception.IncorrectParameterException: Failed to date mail configuration. Settings not found!”这个错误，以为是哪里配置文件有问题，所以导致项目一直运行不起来。然后搜到一篇博客介绍修改一些thingsboard的一些配置文件，然后用下面的这个命令执行过，这次执行速度要很快，不知道跟我修改ingsboard/pom.xml的两个配置有没有关系，但是我修复运行的这个报错信息，肯定不是因为修改这个配置才可以运行成功。
这个是一个很关键的步骤，我觉得对于我这个新手来说，这个步骤给忽略了，如果没有在做这个步骤，在运行ThingsboardServerApplication这个类，启动服务的时候，会一直抛出“org.thingsboard.server.dao.exception.IncorrectParameterException: Failed to date mail configuration. Settings not found!”这个异常，报错信息如下：
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
