Question

获取以下代码的错误

  package jdbcdrive;

import java.sql.*;
public class Lpt {

    /**
     * @param args
     * @throws SQLException
     */
    public static void main(String[] args) throws SQLException {

        Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/lpt?autoReconnect=true&useSSL=false","root","2664");

        Statement st = con.createStatement();

        ResultSet rs = st.executeQuery("SELECT * FROM sys.lpt");

        while(rs.next()) {

            System.out.println(rs.getInt("BatchName")+" "+rs.getString("StudentName")+" "+rs.getString("StudentName")+" "+rs.getString("studentMobileNo")+" "+rs.getString("Address"));
        }

    }

}

我得到的输出错误是

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

尝试将此添加到您的连接字符串：＆＃34; useUnicode = true＆amp; useJDBCCompliantTimezoneShift = true＆amp; useLegacyDatetimeCode = false＆amp; serverTimezone = UTC＆＃34; 它对我有用
