伺服器啟動500日誌顯示MySQL-AB JDBC Driver] will not be managed by Spring
相信有很多小夥伴跟我一樣剛寫完程式一測試就是錯誤500,不要著急,對於ssm初學者來說,出問題很正常一個個解決就行了。
*MySQL-AB JDBC Driver] will not be managed by Spring
[16:17:16.825][DEBUG][com.mmall.dao.UserMapper.checkEmail][http-nio-8080-exec-4] ==> Preparing: SELECT COUNT (1) FROM mmall_user WHERE email = ?*
很明顯 這個錯誤是dao層的,繼續定位,我發現是sql語句的錯誤,count (1)中間不能有空格。去掉空格就好了,所以如果是類似的錯誤請檢查sql語句。
