Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdb

今天换了mysql8，通过jetty启动时报了一连串的异常信息 如下：

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver...

 

控制台提示信息表明数据库驱动com.mysql.jdbc.Driver已经被弃用了、应当使用新的驱动com.mysql.cj.jdbc.Driver

所以，按照提示更改配置文件spring.properties中数据库连接驱动即可。

之后，重新启动发现还报下面异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [spring.xml]: Invocation of init method failed; nested exception is java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

Caused by: java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
 

这是时间报错，没有指定明确的时区,需要在url 后面加上&serverTimezone=UTC

Sat Jun 01 21:45:21 CST 2019 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.

mysql8会询问是否SSL连接，返回一个Boolean值，我们需要手动指定true或者false。需要在url 后面加上&useSSL=false.

完整配置参考如下：

#数据源配置信息
spring.jdbc.driverClass=com.mysql.cj.jdbc.Driver
spring.jdbc.jdbcUrl=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false
spring.jdbc.user=root
spring.jdbc.password=root
