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);
	}
