使用Spring + JMail 发送QQ邮件

1. Email模型实体类

package com.spring.email;

import java.io.File;
import java.util.Date;

public class MailBean {

	//发送邮件账号
	private String from;
	//接收邮件账号集合
	private String[] tos = {};
	//密送邮件账号集合
	private String[] bcc = {};
	//抄送邮件账号集合
	private String[] cc = {};
	//回复地址
	private String relpyTO;
	//文本或HTML
	private String text;
	//主题
	private String subject;
	//日期
	private Date date;
	//附件
	private File[] files = {}; 
	
	public String getFrom() {
		return from;
	}

	public void setFrom(String from) {
		this.from = from;
	}

	public String[] getTos() {
		return tos;
	}

	public void setTos(String[] tos) {
		this.tos = tos;
	}

	public String[] getBcc() {
		return bcc;
	}

	public void setBcc(String[] bcc) {
		this.bcc = bcc;
	}

	public String[] getCc() {
		return cc;
	}

	public void setCc(String[] cc) {
		this.cc = cc;
	}

	public String getRelpyTO() {
		return relpyTO;
	}

	public void setRelpyTO(String relpyTO) {
		this.relpyTO = relpyTO;
	}

	public String getText() {
		return text;
	}

	public void setText(String text) {
		this.text = text;
	}

	public String getSubject() {
		return subject;
	}

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

	public Date getDate() {
		if(date==null){date = new Date();}
		return date;
	}

	public void setDate(Date date) {
		this.date = date;
	}

	public File[] getFiles() {
		return files;
	}

	public void setFiles(File[] files) {
		this.files = files;
	}
}
