自己写的邮件发送功能，可以支持发送内容，发送多个图片和多个附件。

分享给大家，下面是我发送邮件的源码，贴过去用吧

首先准备一个Email对象，用于封装前台传递的数据。（如果你不需要前台的交互，可以不用这个对象）

package com.kewei.emailSender;import java.io.Serializable;public class Email implements Serializable {private String id;private String sender; // 发送人private String to; // 发给谁private String cc; // 抄送人 多个private String bcc; // 暗送人 多个private String subject; // 主题private String sendDate; // 发送时间private boolean replySign; // 要求回执private boolean containAttach; // 是否包含附件private String imagePath; // 邮件图片的路劲 （多个，使用"|"拼接）private String attachPath; // 邮件附件的路径 （多个，使用"|"拼接）private String content; // 邮件的文本内容private boolean isRead; // 是否已读public Email() {super();}public String getId() {return id;}public void setId(String id) {this.id = id;}public boolean isRead() {return isRead;}public void setRead(boolean isRead) {this.isRead = isRead;}public String getContent() {return content;}public void setContent(String content) {this.content = content;}public String getTo() {return to;}public void setTo(String to) {this.to = to;}public String getCc() {return cc;}public void setCc(String cc) {this.cc = cc;}public String getBcc() {return bcc;}public void setBcc(String bcc) {this.bcc = bcc;}public String getSubject() {return subject;}public void setSubject(String subject) {this.subject = subject;}public String getSendDate() {return sendDate;}public void setSendDate(String sendDate) {this.sendDate = sendDate;}                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             public String getImagePath() {return imagePath;}public void setImagePath(String imagePath) {this.imagePath = imagePath;    }public String getAttachPath() {return attachPath;}public void setAttachPath(String attachPath) {this.attachPath = attachPath;}public boolean isReplySign() {return replySign;}public void setReplySign(boolean replySign) {this.replySign = replySign;}public boolean isContainAttach() {return containAttach;}public void setContainAttach(boolean containAttach) {this.containAttach = containAttach;}public String getSender() {return sender;}public void setSender(String sender) {this.sender = sender;}}

根据类的单一职能原则，再准备一个EmailMessage对象，辅助邮件进行发送

package com.kewei.emailSender;import java.io.Serializable;import java.math.BigInteger;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import java.util.Random;public class EmailMessage implements Serializable{private Email email;//邮件//private HttpServletRequest request;private String emailAccount; //发件人private String receiver; //收件人private String protocol; //使用协议private String host;//邮箱服务器private String auth;//是否请求认证private String username;//用户名private String password;//密码private String cc; // 抄送private String bcc; // 暗送private String subject; // 主题private String charset; // 字符编码private boolean receipt; // 回执private String content; // 文本private Map<String, String> map=new HashMap<String, String>();  //发送邮件处理图片所需的内容private List<String> attacPaths; //发送邮件附件/** * @return  protocol */public String getProtocol() {return "smtp";}/** * @param protocol  */public void setProtocol(String protocol) {this.protocol = protocol;}/** * @return  host */public String getHost() {return EmailUtils.getMailServerHost(email.getSender());}/** * @param host  */public void setHost(String host) {this.host = host;}/** * @return  auth */public String getAuth() {return "true";}/** * @param auth  */public void setAuth(String auth) {this.auth = auth;}/** * @return  username */public String getUsername() {return this.username;}/** * @param username  */public void setUsername(String username) {this.username = username;}/** * @return  password */public String getPassword() {return this.password;}/** * @param password  */public void setPassword(String password) {this.password = password;}/** * @return  cc */public String getCc() {return email.getCc();}/** * @param cc  */public void setCc(String cc) {this.cc = cc;}/** * @return  bcc */public String getBcc() {return email.getBcc();}/** * @param bcc  */public void setBcc(String bcc) {this.bcc = bcc;}/** * @return  subject */public String getSubject() {return email.getSubject();}/** * @param subject  */public void setSubject(String subject) {this.subject = subject;}/** * @return  charset */public String getCharset() {return "UTF-8";}/** * @param charset  */public void setCharset(String charset) {this.charset = charset;}public boolean isReceipt() {return email.isReplySign();}public void setReceipt(boolean receipt) {this.receipt = receipt;}/** * @return  content */public String getContent() {if(map==null||map.size()==0){return email.getContent();}return content;}/** * @param content  */public void setContent(String content) {this.content = content;}/** * @return  emailAccount */public String getEmailAccount() {return email.getSender();}/** * @param emailAccount  */public void setEmailAccount(String emailAccount) {this.emailAccount = emailAccount;}/** * @return  receiver */public String getReceiver() {return email.getTo();}/** * @param receiver  */public void setReceiver(String receiver) {this.receiver = receiver;}public Map<String, String> getMap() {//如果图片路径为null,直接返回nullif(email.getImagePath()==null||"".equals(email.getImagePath().trim())){return null;}StringBuffer sb=new StringBuffer();sb.append(email.getContent());//处理邮件中图片和附件的路径for (String realImgPath : email.getImagePath().split("\\|")) {String cid=genPK();//String cid=System.currentTimeMillis()+"";map.put(realImgPath, cid);sb.append("<br/><img src='cid:").append(cid).append("'").append("/>");}//设置文本setContent(sb.toString());return map;}public void setMap(Map<String, String> map) {this.map = map;}public List<String> getAttacPaths() {//如果附件路径为null,直接返回nullif(email.getAttachPath()==null||"".equals(email.getAttachPath().trim())){return null;}List<String> attachList=new ArrayList<String>();for (String realAttachPath : email.getAttachPath().split("\\|")) {attachList.add(realAttachPath);}return attachList;}public EmailMessage(Email email) {super();this.email = email;}public static String genPK() {return new BigInteger(165, new Random()).toString(36).toUpperCase();}}

提供一个EmailUtils 工具类，用于获取邮件服务器和验证邮件地址

package com.kewei.emailSender;import java.util.regex.Matcher;import java.util.regex.Pattern;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;/** * @Description: 处理邮件的工具类 * @author huhao * @date Dec 26, 2013 5:32:38 PM */public class EmailUtils {private static Log logger = LogFactory.getLog(EmailUtils.class);// huhao19920306@163.com 通过@之后的是163还是qq，动态的判断邮件服务器pop.163.com// 994822422@qq.compublic static String getMailServerHost(String emailAddress) {if (emailAddress == null || "".equals(emailAddress.trim())) {throw new RuntimeException("邮件账户错误！");}StringBuffer sb = new StringBuffer();sb.append("smtp.");emailAddress = emailAddress.substring(emailAddress.lastIndexOf("@") + 1);sb.append(emailAddress);return sb.toString().trim();}// 验证邮箱地址public static boolean checkEmail(String email) {boolean flag = false;try {//String check = "^([a-z0-9A-Z]+[-|_|\\.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?\\.)+[a-zA-Z]{2,}$";String check =  "^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+((\\.[a-zA-Z0-9_-]{2,3}){1,2})$";Pattern regex = Pattern.compile(check);Matcher matcher = regex.matcher(email);flag = matcher.matches();} catch (Exception e) {logger.error("邮箱地址错误！");flag = false;}return flag;}public static void main(String[] args) {System.out.println(checkEmail("1@163.ke.com"));}}

最后是一个邮件发送对象EmailSender，发送邮件就交给它了

package com.kewei.emailSender;import java.io.UnsupportedEncodingException;import java.util.ArrayList;import java.util.Date;import java.util.List;import java.util.Map;import java.util.Properties;import java.util.Map.Entry;import javax.activation.DataHandler;import javax.activation.FileDataSource;import javax.mail.Authenticator;import javax.mail.MessagingException;import javax.mail.PasswordAuthentication;import javax.mail.Session;import javax.mail.Transport;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;/** *@decrisption实现邮件的发送 *@author huhao *@version Nov 19, 2013 11:47:47 AM *  @since JDK1.6.0_10 spring3.2.0 */public class MailSender {private MimeMessage msg;/** * @param msg  */private EmailMessage emailMessage;public MailSender() {super();}/** *  *  发送邮件,可发送多个图片和附件                                                                                       *@author huhao *  @date Nov 19, 2013 10:25:44 AM *  @param ms * @throws EmailSendException  * @throws UnsupportedEncodingException  * */public void sendEmail(EmailMessage ms) {try {//得到环境对象getMimeMessage(ms);       msg.setFrom(new InternetAddress(ms.getEmailAccount()));  String [] receiverArray=ms.getReceiver().trim().split(",|，");//收件人InternetAddress数组InternetAddress [] receiverAddressArray=new InternetAddress[receiverArray.length];for (int i = 0;

}msg.setSubject(ms.getSubject());   //主题MimeMultipart mmp  = new MimeMultipart();Map<String, String> map=ms.getMap();//得到邮件内容if(map==null){mmp.addBodyPart(getTextPart(ms.getContent(), ms.getCharset()));}//得到所有的图片if(map!=null){   mmp.addBodyPart(getTextPart(ms.getContent(), ms.getCharset()));List<MimeBodyPart> imageParts=getImageParts(map);for (MimeBodyPart imagePart : imageParts) {mmp.addBodyPart(imagePart);}}//得到所有的附件List<String> attachPaths =ms.getAttacPaths();if(attachPaths!=null){List<MimeBodyPart> attchParts=getAttachmentParts(attachPaths);for (MimeBodyPart attchPart : attchParts) {mmp.addBodyPart(attchPart);}}msg.setSentDate(new Date());

那么如何调用MailSender进行邮件的发送呢？

如果你需要和前端进行交互，可以使用email对象进行封装数据，在将email对象传递个emailMessage对象。

如果不需要的话，你可以修改一下我的代码。直接将数据传递给emailmessage对象。进行邮件的发送
