尝试访问日期字段时DB2为nio.unsupportedcharsetexception CP836

SELECT * FROM SYSIBM.SYSCAT.CHARACTER_SETS;

jdbc:db2://hostname:port/database:charset=UTF-8;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DB2ConnectionExample {
    public static void main(String[] args) {
        String url = "jdbc:db2://hostname:port/database:charset=UTF-8";
        String user = "username";
        String password = "password";

        try (Connection conn = DriverManager.getConnection(url, user, password)) {
            System.out.println("Connected to the database!");
        } catch (SQLException e) {
            System.err.println("Failed to connect to the database: " + e.getMessage());
        }
    }
}
