起因 在我们的固有认知中, mysql-connector-java-5.x.x 连接的是 MySQL5 ,而 mysql-connector-java-8.x.x 连接的是 MySQL8 如果用 mysql-connector-java-5.x.x 连接 MySQL8 ,或者用 mysql-connector-java-8.x.x 连接 MySQL5 ,会出问题 至于出什么问题,呃...,我没想过,也没试过,我相信你们也是一...
下载连接器文件。 按照您的系统架构选择mysql-connector-java-5.1.46.jar或mysql-connector-java-5.1.46-bin.jar连接器文件。它们都可以从MySQL官方网站(https://dev.mysql.com/downloads/connector/j/)或Maven中央存储库(https://mvnrepository.com/artifact/...
说的详细点就是:mysql-connector-java 5.1.26适配的是COLLATIONS的bigint类型的ID,而非bigint unsigned类型的ID 说的抽象点就是:上岸第一剑 先斩意中人,MySQL从 5 上岸到了 8,mysql-connector-java如果不跟着上岸的话,会被第一个斩杀 Unknown system variable 'query_cache_size' 因为用的是都说了能不动就...

MySQL的JDBC驱动，即mysql-connector-java-5.1.5，并不是在MySQL的安装目录中自带的，而是需要单独下载的。如果你已经安装了MySQL的服务端环境，那么你需要去官方网站或者其他可靠来源下载这个驱动。MySQL-Connector/J是专门为Java开发环境设计的。你可以从MySQL的官方网站下载mysql-connector-java-5.1.5...
解决如下 若mysql-connector-java > 5 例如: <dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.17</version></dependency> 需要在数据库连接后加上?useSSL=false url: jdbc:mysql://192.168.56.10:3306/gulimall_pms?useSSL=false...
MySQL 8 取消了查询缓存,而 MySQL 5 异常提示的已经很明显了,我们来验证下 MySQL 5.7.36 是有系统变量 query_cache_size MySQL 8.0.26 mysql-connector-java 升级到 5.1.42 ,启动还是异常: Unknown system variable 'query_cache_size' Could not create connection to database server MySQL 5.7.36 做对比,...
需要另外下载的,你是安装了mysql的windows环境的服务端，mysql-connector-java-5.1.5是mysql在java开发环境下的JDBC驱动。到这个地址去下载：压缩包里面的mysql-connector-java-5.1.6-bin.jar就是mysql的jdbc驱动
