该楼层疑似违规已被系统折叠 隐藏此楼查看此楼

试过百度的各种方法；把数据库都卸载重装；赋予root权限；还有改密码。。。。求大神看看怎么错了

try {

Class.forName("com.mysql.jdbc.Driver"); //加载MYSQL JDBC驱动程序

//Class.forName("org.gjt.mm.mysql.Driver");

System.out.println("加载驱动成功!");

}

catch (Exception e) {

System.out.print("加载驱动失败!");

e.printStackTrace();

}

try {

String url="jdbc:mysql://localhost:3306/comicfm";

String user="root";

String pass="123456";

Connection conn=DriverManager.getConnection(url,user,pass);

System.out.println("数据库连接成功!");

// Statement stmt = conn.createStatement();

//ResultSet rs = stmt.executeQuery("select * from t_user");

//user 为你表的名称

/*while (rs.next()) {

System.out.println(rs.getString("name"));

}*/

}

catch (Exception e) {

System.out.print("数据库连接失败!");

e.printStackTrace();

}

错误代码

加载驱动成功!
