javamail发送邮件报javax.mail.AuthenticationFailedException错误！

 

 需要这两个jar包的支持，下面是一个完整可用的代码，至于我为什么报这个错误的原因，就是因为输入的是qq密码，而不是邮箱独立密码，也提醒其余同学，若碰到此问题，请仔细验证自己的账号密码，以及格式问题

package com.yc.mail;

import java.util.Date;
import java.util.Vector;

public class Mail {
private String title; // 主题
private String inceptAddress; // 收件人地址
private String sendAddress; // 发件人地址
private String content; // 邮件正文
private Vector file; // 附件
private Date sendTime; // 发送时间

public Mail() {
title = "";
inceptAddress = "";
sendAddress = "";
content = "";
file = new Vector();
}

public String getContent() {
return content;
}

public void setContent(String content) {
this.content = content;
}

public Vector getFile() {
return file;
}

public void setFile(Vector file) {
this.file = file;
}

public String getInceptAddress() {
return inceptAddress;
}

public void setInceptAddress(String inceptAddress) {
this.inceptAddress = inceptAddress;
}

public String getSendAddress() {
return sendAddress;
}

public void setSendAddress(String sendAddress) {
this.sendAddress = sendAddress;
}

public Date getSendTime() {
return sendTime;
}

public void setSendTime(Date sendTime) {
this.sendTime = sendTime;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

// 该方法用于收集附件名
public void attachfile(String fname) {
file.addElement(fname);
}
