Mysql5.x与Mysql8.0.X的几点不同
application.properties的不同
被注释掉的对应 8.0.x 版本的内容.
spring.datasource.driver-class-name=com.mysql.jdbc.Driver //spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.username=root//你的用户名.默认root spring.datasource.password=123456//你的密码.默认root spring.datasource.url=jdbc:mysql://127.0.0.1:3306/sell?characterEncoding=utf-8&useSSL=false //spring.datasource.url=jdbc:mysql://127.0.0.1:3306/sell?useUnicode=true&characterEncoding=UTF8&useSSL=false&serverTimezone=UTC spring.jpa.show-sql=true server.context-path=/sell //server.servlet.context-path=/sell
MySql5.x升级MySql8.x非常简单,一般来说只需要操作两个步骤即可
1. 替换新的jar包
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.18</version> </dependency>
2. 替换新驱动类
com.mysql.cj.jdbc.Driver
3. 替换新url连接,需要指定时区
# 设定时间为东八区
serverTimezone=GMT%2B8
# 完整url
String url="jdbc:mysql://"+dbHost+":"+dbPort+"/"+dbName+"?"
+ "serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8"
+ "&port="+dbPort+"&autoReconnect=true";
