java代碼如何發送QQ郵件

　　近來想寫一個qq之間互相發送郵件的工具.奈何一直報錯服務錯誤:

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

　　查閱網友們的答案說是把smtp.qq.com換成smtp.exmail.qq.com也是不得而入.最終只能退而求其次.用163郵箱發送到指定的qq郵箱.騰訊的服務驗證與其他郵箱不同.雖然qq郵箱不行,但是這邊的163郵箱換成sina什么的也還是可以的.只要換掉服務器即可.當然還得開啟smap服務,這就不用說了.

　　Mail.java,里面配置一些必要的參數:

package email;

import java.io.Serializable;  

@SuppressWarnings("serial")  
public class Mail implements Serializable {  
  
    public static final String ENCODEING = "UTF-8";  
  
    private String host; // 服務器地址  
  
    private String sender; // 發件人的郵箱  
  
    private String receiver; // 收件人的郵箱  
  
    private String name; // 發件人昵稱  
  
    private String username; // 賬號  
  
    private String password; // 密碼  
  
    private String subject; // 主題  
  
    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) {  
        // 發送email  
        HtmlEmail email = new HtmlEmail();  
        try {  
            // 這里是SMTP發送服務器的名字：163的如下："smtp.163.com"  
            email.setHostName(mail.getHost());  
            // 字符編碼集的設置  
            email.setCharset(Mail.ENCODEING);  
            // 收件人的郵箱  
            email.addTo(mail.getReceiver());  
            // 發送人的郵箱  
            email.setFrom(mail.getSender(), mail.getName());  
            // 如果需要認證信息的話，設置認證：用戶名-密碼。分別為發件人在郵件服務器上的注冊名稱和密碼  
            email.setAuthentication(mail.getUsername(), mail.getPassword());  
            // 要發送的郵件主題  
            email.setSubject(mail.getSubject());  
            // 要發送的信息，由於使用了HtmlEmail，可以在郵件內容中使用HTML標簽  
            email.setMsg(mail.getMessage());  
            // 發送  
            email.send();  
            if (logger.isDebugEnabled()) {  
                logger.debug(mail.getSender() + " 發送郵件到 " + mail.getReceiver());  
            }  
            return true;  
        } catch (EmailException e) {  
            e.printStackTrace();  
            logger.info(mail.getSender() + " 發送郵件到 " + mail.getReceiver()  
                    + " 失敗");  
            return false;  
        }  
    }  
    public static void main(String[] args) {  
        Mail mail = new Mail();  
        mail.setHost("smtp.163.com"); // 設置郵件服務器,如果不用163的,自己找找看相關的  
        mail.setSender("***@163.com");  
        mail.setReceiver("***@qq.com"); // 接收人  
        mail.setUsername("***@163.com"); // 登錄賬號,一般都是和郵箱名一樣吧  
        mail.setPassword("******"); // 發件人郵箱的登錄密碼  
        mail.setSubject("aaaaaaaaa");  
        mail.setMessage("收到請回復");  
        new MailUtil().send(mail);  
    } 
  
}  

　　在main函數中填寫相應參數就可以發送了.
