問題發生時間(2018-12-27)
環境版本:
- SpringBoot 2.1.1
- Mybatis 1.3.2
原始配置
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
username: hikaricp
password: hikaricp
url: jdbc:mysql://localhost:3306/db_test?characterEncoding=utf-8&useSSL=false

報錯提示
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

解決辦法
從提示中可看出,驅動名稱有變,更正驅動名稱即可
更正後配置
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
username: hikaricp
password: hikaricp
url: jdbc:mysql://localhost:3306/db_test?characterEncoding=utf-8&useSSL=false

同時若使用IDEA自帶提示也可看出問題,有兩種驅動都存在的問題,希望後續修復
另一種解決方案,從SpringBoot2.0之後連線池使用hikari,可根據url自動識別驅動,即如下配置也可成功執行
spring:
datasource:
username: hikaricp
password: hikaricp
url: jdbc:mysql://localhost:3306/db_test?characterEncoding=utf-8&useSSL=false
