com.mysql.jdbc.Driver 是 mysql-connector-java 5中的,
com.mysql.cj.jdbc.Driver 是 mysql-connector-java 6中的java
driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false username=root password= //北京時間東八區 serverTimezone=GMT%2B8 //或者使用上海時間 serverTimezone=Asia/Shanghai
driverClassName=com.mysql.cj.jdbc.Driver url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false username=root password=
driverClassName=com.mysql.cj.jdbc.Driver url=jdbc:mysql://localhost:3306/test?serverTimezone=Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false username=root password=
備註:mysql
I、若是mysql-connector-java用的6.0以上的,以下:sql
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>6.0.6</version> </dependency>
可是你的driver用的仍是com.mysql.jdbc.Driver,就會報錯:安全
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.
此時須要把com.mysql.jdbc.Driver 改成com.mysql.cj.jdbc.Driver服務器
II、還有一個警告:app
WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
不推薦不使用服務器身份驗證來創建SSL鏈接。 若是未明確設置,MySQL 5.5.45+, 5.6.26+ and 5.7.6+版本默認要求創建SSL鏈接。 爲了符合當前不使用SSL鏈接的應用程序,verifyServerCertificate屬性設置爲’false’。 若是你不須要使用SSL鏈接,你須要經過設置useSSL=false來顯式禁用SSL鏈接。 若是你須要用SSL鏈接,就要爲服務器證書驗證提供信任庫,並設置useSSL=true。
