java代码如何发送QQ邮件

　　近来想写一个qq之间互相发送邮件的工具.奈何一直报错服务错误:

org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.qq.com:25
    at org.apache.commons.mail.Email.sendMimeMessage(Email.java:1401)
    at org.apache.commons.mail.Email.send(Email.java:1428)
    at email.MailUtil.send(MailUtil.java:31)
    at email.MailUtil.main(MailUtil.java:52)
Caused by: javax.mail.AuthenticationFailedException: 535 Error: ÇëʹÓÃÊÚȨÂëµÇ¼¡£ÏêÇéÇë¿´: http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

　　查阅网友们的答案说是把smtp.qq.com换成smtp.exmail.qq.com也是不得而入.最终只能退而求其次.用163邮箱发送到指定的qq邮箱.腾讯的服务验证与其他邮箱不同.虽然qq邮箱不行,但是这边的163邮箱换成sina什么的也还是可以的.只要换掉服务器即可.当然还得开启smap服务,这就不用说了.

　　Mail.java,里面配置一些必要的参数:

package email;

import java.io.Serializable;  

@SuppressWarnings("serial")
public class Mail implements Serializable {  

    public static final String ENCODEING = "UTF-8";  

    private String host; // 服务器地址  

    private String sender; // 发件人的邮箱  

    private String receiver; // 收件人的邮箱  

    private String name; // 发件人昵称  

    private String username; // 账号  

    private String password; // 密码  

    private String subject; // 主题  

    private String message; // 信息(支持HTML)  

    public String getHost() {
        return host;
    }  

    public void setHost(String host) {
        this.host = host;
    }  

    public String getSender() {
        return sender;
    }  

    public void setSender(String sender) {
        this.sender = sender;
    }  

    public String getReceiver() {
        return receiver;
    }  

    public void setReceiver(String receiver) {
        this.receiver = receiver;
    }  

    public String getName() {
        return name;
    }  

    public void setName(String name) {
        this.name = name;
    }  

    public String getUsername() {
        return username;
    }  

    public void setUsername(String username) {
        this.username = username;
    }  

    public String getPassword() {
        return password;
    }  

    public void setPassword(String password) {
        this.password = password;
    }  

    public String getSubject() {
        return subject;
    }  

    public void setSubject(String subject) {
        this.subject = subject;
    }  

    public String getMessage() {
        return message;
    }  

    public void setMessage(String message) {
        this.message = message;
    }  

}  

　　 MailUtil.java:

package email;

import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
import org.apache.log4j.Logger;  

public class MailUtil {  

    protected final Logger logger = Logger.getLogger(getClass());  

    public boolean send(Mail mail) {
        // 发送email
        HtmlEmail email = new HtmlEmail();
        try {
            // 这里是SMTP发送服务器的名字：163的如下："smtp.163.com"
            email.setHostName(mail.getHost());
            // 字符编码集的设置
            email.setCharset(Mail.ENCODEING);
            // 收件人的邮箱
            email.addTo(mail.getReceiver());
            // 发送人的邮箱
            email.setFrom(mail.getSender(), mail.getName());
            // 如果需要认证信息的话，设置认证：用户名-密码。分别为发件人在邮件服务器上的注册名称和密码
            email.setAuthentication(mail.getUsername(), mail.getPassword());
            // 要发送的邮件主题
            email.setSubject(mail.getSubject());
            // 要发送的信息，由于使用了HtmlEmail，可以在邮件内容中使用HTML标签
            email.setMsg(mail.getMessage());
            // 发送
            email.send();
            if (logger.isDebugEnabled()) {
                logger.debug(mail.getSender() + " 发送邮件到 " + mail.getReceiver());
            }
            return true;
        } catch (EmailException e) {
            e.printStackTrace();
            logger.info(mail.getSender() + " 发送邮件到 " + mail.getReceiver()
                    + " 失败");
            return false;
        }
    }
    public static void main(String[] args) {
        Mail mail = new Mail();
        mail.setHost("smtp.163.com"); // 设置邮件服务器,如果不用163的,自己找找看相关的
        mail.setSender("***@163.com");
        mail.setReceiver("***@qq.com"); // 接收人
        mail.setUsername("***@163.com"); // 登录账号,一般都是和邮箱名一样吧
        mail.setPassword("******"); // 发件人邮箱的登录密码
        mail.setSubject("aaaaaaaaa");
        mail.setMessage("收到请回复");
        new MailUtil().send(mail);
    } 

}  

　　在main函数中填写相应参数就可以发送了.
