組態檔加載失敗？uj5u.com熱心網友回復：
"Failed to determine a suitable driver class" 組態檔里的資料庫驅動配了嗎uj5u.com熱心網友回復：
組態檔名：application.yml內容：
spring:
dataSource:
url: jdbc:mysql://localhost:3306/myoa
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
uj5u.com熱心網友回復：
用Project Sources and Drivers測驗可以連接資料庫uj5u.com熱心網友回復：
com.mysql.jdbc.Driver 是 mysql-connector-java 5及5之前的，com.mysql.cj.jdbc.Driver 是 mysql-connector-java 6及6之后的的
uj5u.com熱心網友回復：
你看下是不是驅動版本不對uj5u.com熱心網友回復：
版本改過，還是不行
uj5u.com熱心網友回復：
還是不行是同一個原因嗎？ 還是不一樣的錯誤uj5u.com熱心網友回復：
6以后的版本需要在后面加上時區driverClassName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql:///db1?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai
username=root
password=root
uj5u.com熱心網友回復：
改版本沒效果uj5u.com熱心網友回復：
沒效果，我所有版本按照視頻中的版本都沒用
uj5u.com熱心網友回復：
反正看報錯資訊就是xml組態檔報錯，然后我記得tkmybatis在dao注解的時候有兩個tkmapper，別引入錯了uj5u.com熱心網友回復：
