這篇文章跟大家介紹一下om.mysql.jdbc.Driver和com.mysql.cj.jdbc.Driver的差別。有一定的參考價值,有需要的朋友可以參考一下,希望對大家有幫助。
com.mysql.jdbc.Driver
是mysql-connector-java 5中的,
com.mysql .cj.jdbc.Driver
是mysql-connector-java 6中的

com.mysql.jdbc.Driver:
driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false username=root password=
com.mysql.cj.jdbc .Driver, 需要指定時區serverTimezone:
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=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false username=root password=
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>6.0.6</version> </dependency>
com.mysql.jdbc.Driver,就會報錯:
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.
com.mysql.jdbc.Driver 改為
com .mysql.cj.jdbc.Driver
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.
verifyServerCertificate屬性設定為’false’。
useSSL=false來明確停用SSL連線。
useSSL=true。
