mysql版本报错

IntelliJIdea2019.3打开原项目报mysql版本报错：

Error opening zip file or JAR manifest missing : /C:/Users/flycat/.IntelliJIdea2019.3/config/plugins/mysql-explain/lib/mysql-explain-agent-jar-with-dependencies.jar

查看MYSQL版本，原来是5.1.40，直接调整为8.0.19解决方法：<mysql.version>8.0.19</mysql.version>

<dependency>    <groupId>mysql</groupId>    <artifactId>mysql-connector-java</artifactId>    <version>${mysql.version}</version>    <scope>runtime</scope></dependency>依然报错，进一步分析，MYSQL8的连接串是com.mysql.cj.jdbc.Driver，V5的是com.mysql.jdbc.Driver且需要在URL中加入&useSSL=false&&serverTimezone=CST

数据库连接配置也要做相应的调整：

type: com.alibaba.druid.pool.DruidDataSourceurl: jdbc:mysql://localhost:3306/smartfactory?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&useSSL=false&&serverTimezone=CSTusername: rootpassword: connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000;password=${spring.datasource.password}driverClassName: com.mysql.cj.jdbc.Driver
