最近在做一些数据库连接方面的测试的时候,总是会出现各种各样的问题,现将示例代码写出:

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());
           }
       }
   }

再将执行后所产生的错误如下:
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:

哪位高手有时间指点一二啊,急啊.不甚感激之至啊.谢谢!
