最近在做一些數(shù)據(jù)庫連接方面的測試的時候,總是會出現(xiàn)各種各樣的問題,現(xiàn)將示例代碼寫出:

import com.mysql.jdbc.*;
import java.sql.*;

   public class TestMySQL
   {
       public static void main(String[] args)
       {
           try
           {
               Class.forName("com.mysql.jdbc.Driver");
               DriverManager.registerDriver(new com.mysql.jdbc.Driver());
            
   
               Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/BookDB?useUnicode=true&characterEncoding=GB2312", "user", "password");
           }
           catch (Exception e)
           {
               System.out.println(e.getMessage());
           }
       }
   }

再將執(zhí)行后所產(chǎn)生的錯誤如下:
Communication link failure: java.io.IOException, underlying cause: Unexpected end of input stream

** BEGIN NESTED EXCEPTION **

java.io.IOException
MESSAGE: Unexpected end of input stream

STACKTRACE:

哪位高手有時間指點一二啊,急啊.不甚感激之至啊.謝謝!
