楼主

我用的是myeclipse开发工具，我用加载mysql驱动包，这是简单的测试代码：

java.sql.Connection conn=null;
try{
      Class.forName("org.gjt.mm.mysql.Driver").newInstance();
      conn=java.sql.DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","0215");
      System.out.println("数据库连接成功");
}catch(Exception ex){
ex.printStackTrace();
}

出现的错误代码：
