采用JavaMail发送邮件
1. Mail.java
邮件类，需要设置： 帐户名和密码、收件人、抄送人（可选）、暗送人（可选）、主题、内容、附件（可选）
package com.javaweb.mail; import java.util.ArrayList; import java.util.List; /** * 邮件类，需要设置： 帐户名和密码、收件人、抄送人（可选）、暗送人（可选）、主题、内容、附件（可选） * 在创建了Mail对象之后 * 可以调用它的setSubject()、setContent()，设置主题和正文 * 也可以调用setFrom()和 addToAddress()，设置发件人，和添加收件人。 * 也可以调用addAttch()添加附件 * 创建AttachBean：new AttachBean(new File("..."), "fileName"); * @author Administrator * */ public class Mail { private String from; // 发件人 private StringBuilder toAddress = new StringBuilder();//收件人 private StringBuilder ccAddress = new StringBuilder();//抄送 private StringBuilder bccAddress = new StringBuilder();//暗送 private String subject;// 主题 private String content;//正文 // 附件列表 private List<AttachBean> attachs = new ArrayList<AttachBean>(); public Mail() { super(); } public Mail(String from, String to, String subject, String content) { super(); this.from = from; this.toAddress.append(to); this.subject = subject; this.content = content; } /** * 返回发送人 * @return */ public String getFrom() { return from; } /** * 设置发送人 * @param from */ public void setFrom(String from) { this.from = from; } /** * 获取收件人 * @return */ public String getToAddress() { return toAddress.toString(); } /** * 添加收件人，可以添加多个收件人 * @param toAddress */ public void addToAddress(String to) { if(this.toAddress.length() > 0){ this.toAddress.append(","); } this.toAddress.append(to); } /** * 获取暗送人 * @return */ public String getCcAddress() { return ccAddress.toString(); } /** * 添加抄送人，可以添加多个抄送人 * @param cc */ public void addCcAddress(String cc) { if(this.ccAddress.length()>0){ this.ccAddress.append(","); } this.ccAddress.append(cc).toString(); } /** * 获取暗送人 * @return */ public String getBccAddress() { return bccAddress.toString(); } /** * 添加暗送人，可以添加多个暗送人 * @param bccAddress */ public void addBccAddress(String bcc) { if(this.bccAddress.length()>0){ this.bccAddress.append(","); } this.bccAddress.append(bcc); } /** * 获取主题 * @return */ public String getSubject() { return subject; } /** * 设置主题 * @param subject */ public void setSubject(String subject) { this.subject = subject; } /** * 获取正文内容 * @return */ public String getContent() { return content; } /** * 设置正文内容 * @param content */ public void setContent(String content) { this.content = content; } /** * 获取所有附件 * @return */ public List<AttachBean> getAttachs() { return attachs; } /** * 添加附件，可以添加多个附件 * @param attach */ public void addAttachs(AttachBean attach) { this.attachs.add(attach); } }
2. AttachBean.java 附件类
package com.javaweb.mail; import java.io.File; /** * 附件类 * @author Administrator * */ public class AttachBean { private String cid; private File file; private String fileName; public String getCid() { return cid; } public void setCid(String cid) { this.cid = cid; } public File getFile() { return file; } public void setFile(File file) { this.file = file; } public String getFileName() { return fileName; } public void setFileName(String fileName) { this.fileName = fileName; } public AttachBean() { super(); } public AttachBean(File file, String fileName) { super(); this.file = file; this.fileName = fileName; } }
3.MailUtils.java
JavaMail工具类 两方法：1. 获取 Session createSession(String host, final String userName, final String password)
2. 发送邮件 send(Session session,final Mail mail)
package com.javaweb.mail; import java.io.IOException; import java.util.List; import java.util.Properties; import javax.mail.Authenticator; import javax.mail.Message.RecipientType; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; import javax.mail.internet.MimeUtility; public class MailUtils { /** * 创建Session * @param host 服务器名 * @param userName 帐户名 * @param password 帐户密码 * @return */ public static Session createSession(String host, final String userName, final String password){ Properties props = new Properties(); props.setProperty("mail.host", host);// 设置主机名称 props.setProperty("mail.smtp.auth", "true");//指定验证 // 创建验证器 Authenticator auth = new Authenticator(){ public PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(userName, password); } }; // 返回Session return Session.getInstance(props, auth); } /** * 发邮件 * @param session * @param mail * @throws AddressException * @throws MessagingException * @throws IOException */ public static void send(Session session,final Mail mail) throws AddressException, MessagingException, IOException{ MimeMessage msg = new MimeMessage(session); msg.setFrom(new InternetAddress(mail.getFrom()));//设置发件人 msg.setSubject(mail.getSubject());// 设置主题 msg.addRecipients(RecipientType.TO, mail.getToAddress());//收件人 String cc = mail.getCcAddress(); if(cc != null){ msg.addRecipients(RecipientType.CC, cc);// 抄送 } String bcc = mail.getBccAddress(); if(bcc != null){ msg.addRecipients(RecipientType.BCC, bcc);// 暗送 } //创建部件集对象 MimeMultipart multipart = new MimeMultipart(); // 创建一个部件 MimeBodyPart bodyPart = new MimeBodyPart(); bodyPart.setContent(mail.getContent(), "text/html;charset=utf-8"); multipart.addBodyPart(bodyPart);//把部件设置到部件集中 // 添加附件 List<AttachBean> attachBeanList = mail.getAttachs(); if(attachBeanList != null){ for(AttachBean attach : attachBeanList){ MimeBodyPart attachPart = new MimeBodyPart(); attachPart.attachFile(attach.getFile());// 设置附件文件 // 设置文件名 attachPart.setFileName(MimeUtility.encodeText(attach.getFileName())); String cid = attach.getCid(); if(cid != null){ attachPart.setContentID(cid); } multipart.addBodyPart(attachPart);//把部件设置到部件集中 } } msg.setContent(multipart);//设置内容 Transport.send(msg);// 发送邮件 } }
