idea jdbc 修改时区之后还是不能连接

import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.junit.Test;

import java.beans.PropertyVetoException;
import java.sql.Connection;

public class DataSourseT {
@Test
public void test1() throws Exception {
ComboPooledDataSource dataSourse = new ComboPooledDataSource();
dataSourse.setDriverClass("com.mysql.cj.jdbc.Driver");
dataSourse.setJdbcUrl("jdbc.url=jdbc:mysql://localhost:3306/db1?serverTimezone=UTC");
dataSourse.setUser("root");
dataSourse.setPassword("109922");
Connection connection = dataSourse.getConnection();
System.out.println(connection);
connection.close();

}

}

报错信息
java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

换成这个试试
jdbc:mysql://localhost:3306/db1?useSSL=false&useUnicode=true&characterEncoding=UTF-8
