一个使用Spring发送邮件的问题

[小鱼的梦]

我是Spring的新手，做个邮件发送遇到问题了，大家帮忙看看
代码如下：
1.beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
	<bean id="mailSender" class="cn.com.action.Senders">
		<property name="mailSender"><ref bean="mailSend"/> </property>
	</bean>   
	<bean id="mailSend" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.sina.com"/>
        <property name="username" value="itsavour"/>
        <property name="password" value="110110"/>
         <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
            </props>
        </property>
        
    </bean>
</beans> 

2.Senders.java

package cn.com.action;

import javax.mail.Message;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.MailException;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessagePreparator;

public class Senders{

    private JavaMailSender mailSender;
    
    public JavaMailSender getMailSender() {
		return mailSender;
	}
	public void setMailSender(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }
    public void placeOrder() {

        // Do the business calculations...

        // Call the collaborators to persist the order...
        
        MimeMessagePreparator preparator = new MimeMessagePreparator() {
        
            public void prepare(MimeMessage mimeMessage) throws Exception {
        
                mimeMessage.setRecipient(Message.RecipientType.TO, 
                        new InternetAddress("[e-mail]"));
                mimeMessage.setFrom(new InternetAddress("[e-mail]"));
                mimeMessage.setText("thank you for placing order. Your order number is");
                }
        };
        try {
            this.mailSender.send(preparator);
        }
        catch (MailException ex) {
            // simply log it and go on...
            System.err.println(ex.getMessage());            
        }
    }
    public static void main(String[] args) {
    	ApplicationContext cxt = new ClassPathXmlApplicationContext("beans.xml");
    	Senders s = (Senders)cxt.getBean("mailSender");
		//Senders s = new Senders();
		s.placeOrder();
	}
}

我在Senders.java中写了个main方法来做测验。但是运行出错啦
错误如下：
Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.sina.com, port: 25;
nested exception is:
java.net.ConnectException: Connection timed out: connect
大家帮忙看看 谢谢啦
分数不多 只为求知 再次谢谢了

错误如下：
Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.sina.com, port: 25;
nested exception is:
java.net.ConnectException: Connection timed out: connect

---------------
连接超时，在自己机器上连接这个端口看看，xp下的命令为： telnet smtp.sina.com 25
先确定自己本机是否可以访问这个地址的25端口。
如果不可以，尝试关闭下防火墙看看。

连接新浪邮件服务器smtp.sina.com, port: 25超时。先看一下sina邮件服务器是这样的吗？还有端口。
telnet 测试一下

我在命令行下输入了连接命令，结果如下：只有一行
220 irxd5-183.sinamail.sina.com.cn ESMTP
是不是没连接上啊

[小鱼的梦]

sina的smtp服务器我查了 是对的 smtp.sina.com 端口新浪没要求 我用的是默认的
命令行连接sina 连接不上 怎么办？？
继续求助中。。。
