MySQL Connector/J 6.x jdbc.properties 配置, mysql-connector-java-6.0.4.jar 异常

Posted 2020-08-13

今天学习SSM框架整合，完成Spring和mybatis这两大框架的整合做测试时候出来很多问题，主要来自于配置文件。

我这里重点说一下mysql数据驱动配置。

配置pom.xml时候去网站 MySQL Connector/J 找到了最新版本，也是出于好奇就配置了...

<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.4</version>
</dependency>

解决问题

原来新版的驱动配置有些变化：

1. url连接必须设置时区

### MySQL Connector/J 5.x   (旧版连接)
#jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8

### MySQL Connector/J 6.x   (新版连接)
jdbc.url=jdbc:mysql:///test?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false

说明： 新版驱动url默认地址为127.0.0.1:3306，所以访问本机mysql数据库地址可以用 /// 表示。

2. 新的驱动类位置有了变化（不影响使用，但会报警告）

### MySQL Connector/J 5.x   (旧版驱动)
#jdbc.driver_class=com.mysql.jdbc.Driver

### MySQL Connector/J 6.x   (新版驱动)
jdbc.driver_class=com.mysql.cj.jdbc.Driver
