Question

我在向Maria DB插入一些字符时遇到问题。我使用的是maria db connector 1.3.2版本。还建议我是否应该插入字符或任何选项将它们转换为utf 8个字符

Hibernate属性：

jdbc.url=jdbc\:mariadb\://localhost\:3306/twitter?useUnicode=true&amp;characterEncoding=utf-8
hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
jdbc.username= root
jdbc.password = 
hibernate.bytecode.use_reflection_optimizer = false
hibernate.show_sql = true
hibernate.validator.apply_to_ddl = false
hibernate.connection.CharSet=utf8
hibernate.connection.characterEncoding=utf8
hibernate.connection.useUnicode = true

以下是日志：

Answer 1

我通过提到utf8_general_ci来创建表，但是它是用latin1_swedish_ci创建的。改变表解决了问题。非常感谢。

更改整理脚本： alter table table_name转换为字符集utf8 collate utf8_general_ci;

非法混合的colria maria db和hibernate
