关于这个工具的创作:相信大家都有找工作的经历，在简历投递的时候是否有这样的烦恼？点对点的发送邮件时，不停的复制粘贴自己的简历发送，在这一期间不仅浪费了大家相当多的一部分时间，而且发送简历的效率也不是很高。于是自己便做了一个这样的小工具，能够进行批量、群发邮件的功能。
一、开发前准备：
必要的jar包：mail.jar、commons-email-1.1.jar、activation.jar
二、代码编写:
MailSenderInfo.java 封装Mail普通dojo类
package cn.com.mes.mail;
import java.util.Date;
/**
* 封装邮件发送对象类

*/
public class MailSenderInfo {
//邮件登录账号
private String username = "";
//邮件登录密码
private String password = "";
//邮件服务器地址
private String hostName = "";
//发件人邮箱地址
private String from = "";
//邮件标题
private String title = "";
//要发送Html文本路径
private String htmlPath = "";
//发送时间
private Date sendDate = null;
public MailSenderInfo (){
}
public MailSenderInfo(String username, String password, String hostName,
String from, String title) {
super();
this.username = username;
this.password = password;
this.hostName = hostName;
this.from = from;
this.title = title;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getHostName() {

}
public void setHostName(String hostName) {
this.hostName = hostName;
}
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getHtmlPath() {
return htmlPath;
}
public void setHtmlPath(String htmlPath) {
this.htmlPath = htmlPath;
}
public Date getSendDate() {
return sendDate;
}
public void setSendDate(Date sendDate) {
this.sendDate = sendDate;
}
}

3.MailSender类：发送邮件封装类
package cn.com.mes.mail;
import java.text.MessageFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import org.apache.commons.mail.HtmlEmail;
import org.apache.log4j.Logger;
/**
* 发送邮件封装类
* @author HuangXiaoyong
*/
public class MailSender implements Runnable {
protected Logger logger = Logger.getLogger(MailSender.class);
private MailSenderInfo mailInfo =null;
private final String tipInfoFormat = "一共需要发送{0}封邮件,成功发送{1}封,失败发送{2}封。\n\r失败邮件列表地址：{3}";
public MailSender(){
mailInfo = MailUtils.getMailSenderInfo();
}
public static void main(String[] args){
Runnable run = new MailSender();
run.run();
}
@Override
public void run() {
String addressPath ="D:\\test\\09-09-09.txt";
List<String> list =MailUtils.getToList(addressPath);
this.sendHtmlEmail(mailInfo,list);
}
public String getResultInfo(int sum ,int success,int fail,List<String> failList ) {
return MessageFormat.format(this.tipInfoFormat, sum,success,
fail, failList.toString());
}
public void sendHtmlEmail(MailSenderInfo info,
List<String> emailAddresslist,
javax.swing.JProgressBar bar){
List<String> fialAddressList = new ArrayList<String>();
bar.setMinimum(0);
bar.setMaximum(emailAddresslist.size()-1);
//收件人邮件地址list集合
int failCount = 0;
int successCount = 0;
try{
for(int i=0;i<emailAddresslist.size();i++){
bar.setValue(i);
String contentText = MailUtils.getStringBufferText(info.getHtmlPath());
boolean flag = sendSingleHtmlEmail(info.getUsername(),
info.getPassword(),
info.getHostName(),
info.getFrom(),
emailAddresslist.get(i),
info.getTitle(),
contentText,
info.getSendDate());
if(flag){
successCount++;
}else{
fialAddressList.add(emailAddresslist.get(i));
failCount++;
}
//发送10封邮件，当前线程休眠2秒
if(i%10 == 0){
Thread.currentThread().sleep(1000*2);
}
}
}catch(Exception ex){
ex.printStackTrace();
}
logger.info(getResultInfo(emailAddresslist.size(),successCount,failCount,fialAddressList));
}
public void sendHtmlEmail(MailSenderInfo info,List<String> emailAddresslist) {
List<String> fialAddressList = new ArrayList<String>();
//收件人邮件地址list集合
int failCount = 0;
int successCount = 0;
try{
for(int i=0;i<emailAddresslist.size();i++){
String contentText = MailUtils.getStringBufferText(info.getHtmlPath());
boolean flag = sendSingleHtmlEmail(info.getUsername(),
info.getPassword(),
info.getHostName(),
info.getFrom(),
emailAddresslist.get(i),
info.getTitle(),
contentText,
info.getSendDate());
if(flag){
successCount++;
}else{
fialAddressList.add(emailAddresslist.get(i));
failCount++;
}
//发送10封邮件，当前线程休眠2秒
if(i%10 == 0){
Thread.currentThread().sleep(1000*2);
}
}
}catch(Exception ex){
ex.printStackTrace();
}
logger.info(getResultInfo(emailAddresslist.size(),successCount,failCount,fialAddressList));
}
/**
*
* 发送单个Html文本邮件
* @param username
* @param password
* @param host
* @param from
* @param to
* @param title
* @param context
* @return
*/
public boolean sendSingleHtmlEmail(String username,
String password,String host,
String from, String to,
String title, String context,Date sendDate ) throws Exception{
logger.info(new Date().toString()+": 开始向"+to+"邮箱发送邮件....");
boolean flag = false;
HtmlEmail email =new HtmlEmail();
email.setAuthentication(username,password);
email.setHostName(host);
email.setCharset("GB2312");
//设置邮件标题
email.setSubject(title);
try{
//设置发件人
email.setFrom(from);
//设置收件人
email.addTo(to);
//Html邮件上下文，邮件内容
email.setHtmlMsg(context);
//设置邮件发送时间
email.setSentDate(sendDate);
email.send();
flag = true;
logger.info(new Date().toString()+":成功发送邮件");
}catch(Exception ex){
logger.error("发送邮件出现异常！");
throw ex;
}
return flag;
}
}
这些是主要后台编写的类，运行效果如下：
首先设置好邮件属性
在添加发送人的邮件列表(.txt)文件，每个邮件地址用逗号(",")分隔开
swing前台代码就不在这里罗列了
不足的地方：前台属性设置的时候没有做校验判断。
遇到的问题有：发送邮件群发到一定的数量的时候，发送邮件失败。虽然我这里采用了多线程，问题依旧存在。
