啓動springboot項目報”CONDITIONS EVALUATION REPORT“

今天給我的springboot項目的最後一步添加日誌之後，日誌文件裏輸出：

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

解決辦法：

• 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類的問題，可以按照這個方式試一下）

• 2、不過倒我這裏yml文件加上了也不管用，很是鬱悶；幾番波折，我留意到控制檯沒有這個信息，但是日誌文件裏有，於是看了日誌的配置文件（log4j.properties），發現文件的日誌級別爲：INFO，而控制檯的是：DEBUG，索性將文件的日誌級別也設置爲：INFO，解決問題！！！
