java利用commons-email发送邮件并进行封装

本例中利用commons-email发送邮件并进行封装，支持html内容和附件；Commons Email是Apache的Commons子项目下的一个邮件客户端组件，它是基于JavaMail的，大大简化了邮件的收发操作。

所需jar包：commons-email-1.4.jar和mail.jar ，jar包下载地址 https://files.cnblogs.com/files/haha12/%E5%8F%91%E9%80%81%E9%82%AE%E4%BB%B6%E6%89%80%E9%9C%80jar%E5%8C%85.rar
代码如下：

MailInfo.java：邮件实体类

package com.test.mail;

import java.util.List;

import org.apache.commons.mail.EmailAttachment;

/**

public class MailInfo {

    private List<String> toAddress = null;
    // 抄送人地址
    private List<String> ccAddress = null;
    // 密送人
    private List<String> bccAddress = null;
    // 附件信息
    private List<EmailAttachment> attachments = null;
    // 邮件主题
    private String subject;
    // 邮件的文本内容
    private String content;


    public List<String> getToAddress() {
        return toAddress;
    }

    public void addToAddress(String toAddress) {
        this.toAddress.add(toAddress);
    }

    public void addToAddress(List<String> toAddress) {
        this.toAddress.addAll(toAddress);
    }

    }

    public List<EmailAttachment> getAttachments() {
        return attachments;
    }

    public void setAttachments(List<EmailAttachment> attachments) {
        this.attachments = attachments;
    }

    public List<String> getBccAddress() {
        return bccAddress;
    }

    public void setBccAddress(List<String> bccAddress) {
        this.bccAddress = bccAddress;
    }

    public String getSubject() {
        return subject;
    }

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