原因: 数据库table和插入语句的字符编码不匹配或者数据库table的编码不支持中文 解决方案: 修改table中的字符编码为:utf-8(或gbk,gb2312) 在代码中链接数据库时,连接字符串后面加上?characterEncoding=utf8,例如jdbc:mysql://localhost:3306/db_zhu?cha
原因:
数据库table和插入语句的字符编码不匹配或者数据库table的编码不支持中文
解决方案:
修改table中的字符编码为:utf-8(或gbk,gb2312)
在代码中链接数据库时,连接字符串后面加上?characterEncoding=utf8,例如jdbc:mysql://localhost:3306/db_zhu?characterEncoding=utf8
在出现插入或修改出现乱码时,首先在mysql终端执行下插入语句,检查是否插入正确。然后再代码中打印下插入语句,看是否有乱码或问号?。最看看连接字符串是否设置了characterEncoding
附:
wamp执行mysql终端时需要mysql -u root 才能有有root权限。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
