以5和8做比较
private static String dbType = "MySql"; //private static String driver = "com.mysql.jdbc.Driver"; // 版本5 private static String driver = "com.mysql.cj.jdbc.Driver"; private static String url = "jdbc:mysql://localhost:3306/plusoft_test?useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true"; //连接数据库(meizu是数据库名) private static String user = "root"; private static String pwd = "root";
Unknown initial character set index ‘255‘ received from server. Initial client character set can be forced via the ‘characterEncoding‘ property.
一般是字符集错误,MYSQL 5.5 之前, UTF8 编码只支持1-3个字节;从MYSQL5.5开始,可支持4个字节UTF编码utf8mb4;
需根据使用的mysql版本更换对应的连接包(mysql-connector-java-5.1.30-bin)。
建表语句也有些不同(8):
CREATE TABLE `t_educational` ( `id` VARCHAR(20) COLLATE utf8mb4_general_ci DEFAULT NULL, `name` VARCHAR(20) COLLATE utf8mb4_general_ci DEFAULT NULL )ENGINE=InnoDB CHARACTER SET ‘utf8mb4‘ COLLATE ‘utf8mb4_general_ci‘
