用Java连接mysql数据库出问题了?求大虾指点........
我的代码:
package connect;

import java.sql.*;

public class Get_message {
public String name;
public String datetime;
public int no;
public String content;
public static void main(String[] args) throws Exception{

Connection con;
Statement stmt;
ResultSet rs;
  Class.forName("com.mysql.jdbc.Driver");
  con = DriverManager.getConnection("jdbc:mysql://localhost:3306/message","User=root","Password=123");
stmt = con.createStatement();
rs = stmt.executeQuery("SELECT no,name,datetime,content FROM message_save ");
while(rs.next())
{
System.out.println(rs.getString("name"));
rs.getString("datetime");
rs.getInt("no");
rs.getString("content");
}
}
}

错误提示代码:

我的用户名和密码绝对没有错误,如果有大虾知道问题出在哪里,请教教小弟,感激不尽啊!

------解决方案--------------------
DriverManager.getConnection("jdbc:mysql://localhost:3306/message","User=root","Password=123");

改为:

DriverManager.getConnection("jdbc:mysql://localhost:3306/message","root","123");
