如何将Java连接到Mysql？

我的Java程序出现这些错误。我已经把mysql-connector-java-5.1.14-bin.jar放在我的类路径中。如何解决这个问题？如何将Java连接到Mysql？

HSystemRDB.java:144: package com.mysql.jdbc does not exist 
    Driver driver = new com.mysql.jdbc.Driver(); 
            ^
HTestClassRDB.java:99: package com.mysql.jdbc does not exist 
     DriverManager.registerDriver(new com.mysql.jdbc.Driver());

代码：

String url = "jdbc:mysql://wire:3306/h?user="+pSystemRDB.USERNAME+"&password="+pSystemRDB.PASSWORD; 
    Connection con; 
    Statement stmt; 
    String query1 = "Delete from dbase"; 
    String query2 = "Delete from id"; 


    try { 
     DriverManager.registerDriver(new com.mysql.jdbc.Driver()); 
    } catch (Exception e) { 
     System.out.println("Class Not Found Exception:"); 
     System.out.println(e.getMessage()); 
    }

那么，它可能没有说谎。你确定mysql连接器在你的类路径中吗？你读过这个吗？ http://dev.mysql.com/doc/refman/5.1/en/connector-j-usagenotes-basic.html#connector-j-usagenotes-connect-drivermanager – Robert 2010-12-08 08:22:50

他可以试试`String s =“java”+“ mysql“;`... :-) – 2010-12-08 10:59:10

您需要从下载MySQL包：here并将其放置在库中，我将修改在少数分钟excact步骤

这是正确的语法连接到数据库：

try 
{ 
    // create a java mysql database connection 
    String myDriver = "org.gjt.mm.mysql.Driver"; 
    String myUrl = "jdbc:mysql://localhost/test"; 
    Class.forName(myDriver); 
    Connection conn = DriverManager.getConnection(myUrl, "root", ""); 

    // your prepstatements goes here... 

    conn.close(); 
} 
catch (Exception e) 
{ 
    System.err.println("Got an exception! "); 
    System.err.println(e.getMessage()); 
}

希望这有助于
