這是我的tomcat的配置

沒看到報錯資訊uj5u.com熱心網友回復：
org.apache.catalina.startup.HostConfig.deployDirectory
和com.mchange.v2.c3p0.C3P0Registry. Initializing c3p0-0.9.5.2不是嗎
uj5u.com熱心網友回復：
怎么判斷哪句是錯誤資訊，哪句是正常資訊呢？uj5u.com熱心網友回復：
黑線以下不是嗎
uj5u.com熱心網友回復：
難道就因為是紅色就是錯誤日志么，但是上面也是紅色，為啥就不是錯誤日志呢？
起碼你的截圖中沒看到任何錯誤日志，黑線下面也是c3p0正常初始化日志。
uj5u.com熱心網友回復：
因為idea老是這樣提醒我切回idea，所以我認為是有錯誤
