找不到合适的驱动程序

问题描述

我正在尝试在Java 6中执行sql查询:

I am trying to execute a sql query in java 6:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;


/**
 *
 * @author ramy
 */
public class JavaTest
{

    public static void main(String[] args)
    {
        try
        {
            String url="jdbc:msql://127.0.0.1:1521;DatabaseName=test";
            Connection ct=DriverManager.getConnection(url,"","");
            Statement st=ct.createStatement();
            ResultSet result;
            result=st.executeQuery("select * from utente");
            while(result.next())
            {
                String temp=result.getString("Num_tessera");
                System.out.println(temp);
            }
            ct.close();
        }
        catch(Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

我已经在Mac Os X上安装了mysql 5.5集群，在URL中，我刚刚编写了本地IP(本地主机)，数据库名称为test.
为什么找不到数据库?我必须安装一些驱动程序吗?我已经安装了数据库，"utente"是一个现有表.

I have installed mysql 5.5 cluster on Mac Os X, in the url I have just written my local IP (localhost), and the database name is test.
Why doesn't it find the database? Do I have to install some driver? I already have the database installed and "utente" is an existing table.

推荐答案

我怀疑问题是您的JDBC URL:

I suspect the problem is your JDBC URL:

"jdbc:msql://..."

你的意思是

"jdbc:mysql://..."

有没有机会?

(是的，您也还需要 MySQL驱动程序在您的类路径中.安装不需要它，但是jar文件将需要可用.)

(And yes, you'll also need the MySQL driver in your classpath. It's not something you need to install, but the jar file will need to be available.)
