How to set up Chinese characters in MySQL connection string?

To set Chinese characters in the MySQL connection string, UTF-8 character encoding can be used. The connection string can be set as follows: 1. Add the parameter `useUnicode=true` to the connection string, indicating the use of Unicode encoding. 2. Add the parameter `characterEncoding=utf8` to the connection string, indicating the use of UTF-8 character encoding. For example, the following connection string can be used to set Chinese encoding:

String url = "jdbc:mysql://localhost:3306/database_name?useUnicode=true&characterEncoding=utf8";
String user = "username";
String password = "password";
Connection connection = DriverManager.getConnection(url, user, password);

This will encode Chinese characters in UTF-8 format through the URL string.
