Spring Boot啟動后 控制台不停的循環輸出：Eagerly caching bean 'userService' to allow for resolving potential circular references 問題

這是我第一次在項目中使用springboot，之前出現過這個問題，后來修改了配置文件后，重新啟動后就好了。

 

　　在日志為輸出級別為INFO的情況下輸出日志：

　　　停到這了，不再輸出。還以為是卡了，后面看了debug的日志才知道。是在循環

　　在日志為輸出級別為DEBUG的情況下輸出日志：

　　　　不停循環的輸出，不帶停的。。。。。

 因為剛接觸springboot 不是特別理解原因所在。還希望路過的大神能夠點播點播。。。
