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 http://files.VEVb.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;/** * 邮件相关信息 *  */public class MailInfo {        // 收件人    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 void addCcAddress(List<String> ccAddress) {        if (null != ccAddress && ccAddress.size() > 0)            this.ccAddress.addAll(ccAddress);    }    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;    }    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }    public void setToAddress(List<String> toAddress) {        this.toAddress = toAddress;    }    public List<String> getCcAddress() {        return ccAddress;    }    public void setCcAddress(List<String> ccAddress) {        this.ccAddress = ccAddress;    }}

MailUtil.java：发送邮件工具类

TestMail.java：发送邮件测试类

package com.test.mail;import java.util.ArrayList;import java.util.List;import org.apache.commons.mail.EmailAttachment;public class TestMail {    /**     * @return void     */    public static void main(String[] args) {        MailInfo mailInfo = new MailInfo();        List<String> toList = new ArrayList<String>();        toList.add("my@163.com");                List<String> ccList = new ArrayList<String>();        ccList.add("my@163.com");                List<String> bccList = new ArrayList<String>();        bccList.add("my@163.com");                //添加附件        EmailAttachment att = new EmailAttachment();        att.setPath("g://测试.txt");        att.setName("测试.txt");        List<EmailAttachment> atts = new ArrayList<EmailAttachment>();        atts.add(att);        mailInfo.setAttachments(atts);                mailInfo.setToAddress(toList);//收件人        mailInfo.setCcAddress(ccList);//抄送人        mailInfo.setBccAddress(bccList);//密送人                mailInfo.setSubject("测试主题");        mailInfo.setContent("内容：<h1>test,测试</h1>");                 MailUtil.sendEmail(mailInfo);    }}
