2020-04-03 15:12:13 [INFO ](TomcatWebServer               )  Tomcat started on port(s): 8080 (http) with context path ''

解决办法：

• 1、在配置文件application.yml或者application.properties文件中加入：

logging.level.org.springframework.boot.autoconfigure: error

（如果看到此篇文章的你也有此类的问题，可以按照这个方式试一下）

• 2、不过倒我这里yml文件加上了也不管用，很是郁闷；几番波折，我留意到控制台没有这个信息，但是日志文件里有，于是看了日志的配置文件（log4j.properties），发现文件的日志级别为：INFO，而控制台的是：DEBUG，索性将文件的日志级别也设置为：INFO，解决问题！！！
