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.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; /** * 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
package com.test.mail; import java.util.List; import org.apache.commons.mail.EmailAttachment; import org.apache.commons.mail.EmailException; import org.apache.commons.mail.HtmlEmail; /** * 发送邮件Util */ public class MailUtil { //邮箱 private static String mailServerHost = "smtp.163.com"; private static String mailSenderAddress = "test@163.com"; private static String mailSenderNick = "test"; private static String mailSenderUsername = "test@163.com"; private static String mailSenderPassword = "xxx"; /** * 发送 邮件方法 (Html格式,支持附件) * * @return void */ public static void sendEmail(MailInfo mailInfo) { try { HtmlEmail email = new HtmlEmail(); // 配置信息 email.setHostName(mailServerHost); email.setFrom(mailSenderAddress,mailSenderNick); email.setAuthentication(mailSenderUsername,mailSenderPassword); email.setCharset("UTF-8"); email.setSubject(mailInfo.getSubject()); email.setHtmlMsg(mailInfo.getContent()); // 添加附件 List<EmailAttachment> attachments = mailInfo.getAttachments(); if (null != attachments && attachments.size() > 0) { for (int i = 0; i < attachments.size(); i++) { email.attach(attachments.get(i)); } } // 收件人 List<String> toAddress = mailInfo.getToAddress(); if (null != toAddress && toAddress.size() > 0) { for (int i = 0; i < toAddress.size(); i++) { email.addTo(toAddress.get(i)); } } // 抄送人 List<String> ccAddress = mailInfo.getCcAddress(); if (null != ccAddress && ccAddress.size() > 0) { for (int i = 0; i < ccAddress.size(); i++) { email.addCc(ccAddress.get(i)); } } //邮件模板 密送人 List<String> bccAddress = mailInfo.getBccAddress(); if (null != bccAddress && bccAddress.size() > 0) { for (int i = 0; i < bccAddress.size(); i++) { email.addBcc(ccAddress.get(i)); } } email.send(); System.out.println("邮件发送成功!"); } catch (EmailException e) { e.printStackTrace(); } } }
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); } }
