我们公司用的QQ企业邮箱，所以本文的例子也是针对QQ企业邮箱。
一、创建邮件信息类MailInfo.java
import java.util.Properties;
public class MailInfo {
private String mailServerHost;// 服务器ip
private String mailServerPort;// 端口
private String fromAddress;// 发送者的邮件地址
private String toAddress;// 邮件接收者地址
private String username;// 登录邮件发送服务器的用户名
private String password;// 登录邮件发送服务器的密码
private boolean validate = false;// 是否需要身份验证
private String subject;// 邮件主题
private String content;// 邮件内容
private String[] attachFileNames;// 附件名称
public Properties getProperties() {
Properties p = new Properties();
p.put("mail.smtp.host", this.mailServerHost);
//p.put("mail.smtp.port", this.mailServerPort);
p.put("mail.smtp.auth", validate ? "true" : "false");
return p;
}
public String getMailServerHost() {
return mailServerHost;
}
public void setMailServerHost(String mailServerHost) {
this.mailServerHost = mailServerHost;
}
public String getMailServerPort() {
return mailServerPort;
}
public void setMailServerPort(String mailServerPort) {
this.mailServerPort = mailServerPort;
}
public String getFromAddress() {
return fromAddress;
}
public void setFromAddress(String fromAddress) {
this.fromAddress = fromAddress;
}
public String getToAddress() {
return toAddress;
}
public void setToAddress(String toAddress) {
this.toAddress = toAddress;
}
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 boolean isValidate() {
return validate;
}
public void setValidate(boolean validate) {
this.validate = validate;
}
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 String[] getAttachFileNames() {
return attachFileNames;
}
public void setAttachFileNames(String[] attachFileNames) {
this.attachFileNames = attachFileNames;
}
}
二、创建发送邮件类SimpleMail（2种方式一种发送html格式邮件；一种发送文本格式邮件）
import java.io.File;
import java.util.Date;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Multipart;
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;
public class SimpleMail {
// 以文本格式发送邮件
public static boolean sendTextMail(MailInfo mailInfo) {
//判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties properties = mailInfo.getProperties();
if (mailInfo.isValidate()) {
//如果需要身份认证，则创建一个密码验证器
authenticator = new MyAuthenticator(mailInfo.getUsername(), mailInfo.getPassword());
}
//根据邮件会话属性和密码验证器构造一个发送邮件的session
Session sendMailSession = Session.getDefaultInstance(properties, authenticator);
try {
Message mailMessage = new MimeMessage(sendMailSession);//根据session创建一个邮件消息
Address from = new InternetAddress(mailInfo.getFromAddress());//创建邮件发送者地址
mailMessage.setFrom(from);//设置邮件消息的发送者
Address to = new InternetAddress(mailInfo.getToAddress());//创建邮件的接收者地址
mailMessage.setRecipient(Message.RecipientType.TO, to);//设置邮件消息的接收者
mailMessage.setSubject(mailInfo.getSubject());//设置邮件消息的主题
mailMessage.setSentDate(new Date());//设置邮件消息发送的时间
//mailMessage.setText(mailInfo.getContent());//设置邮件消息的主要内容
//MimeMultipart类是一个容器类，包含MimeBodyPart类型的对象
Multipart mainPart = new MimeMultipart();
MimeBodyPart messageBodyPart = new MimeBodyPart();//创建一个包含附件内容的MimeBodyPart
//设置HTML内容
messageBodyPart.setContent(mailInfo.getContent(),"text/html; charset=utf-8");
mainPart.addBodyPart(messageBodyPart);
//存在附件
String[] filePaths = mailInfo.getAttachFileNames();
if (filePaths != null && filePaths.length > 0) {
for(String filePath:filePaths){
messageBodyPart = new MimeBodyPart();
File file = new File(filePath);
if(file.exists()){//附件存在磁盘中
FileDataSource fds = new FileDataSource(file);//得到数据源
messageBodyPart.setDataHandler(new DataHandler(fds));//得到附件本身并至入BodyPart
messageBodyPart.setFileName(file.getName());//得到文件名同样至入BodyPart
mainPart.addBodyPart(messageBodyPart);
}
}
}
//将MimeMultipart对象设置为邮件内容
mailMessage.setContent(mainPart);
Transport.send(mailMessage);//发送邮件
return true;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
// 以HTML格式发送邮件
public static boolean sendHtmlMail(MailInfo mailInfo) {
//判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties properties = mailInfo.getProperties();
if (mailInfo.isValidate()) {
// 如果需要身份认证，则创建一个密码验证器
authenticator = new MyAuthenticator(mailInfo.getUsername(), mailInfo.getPassword());
}
// 根据邮件会话属性和密码验证器构造一个发送邮件的session
Session sendMailSession = Session.getDefaultInstance(properties, authenticator);
try{
Message mailMessage = new MimeMessage(sendMailSession);//根据session创建一个邮件消息
Address from = new InternetAddress(mailInfo.getFromAddress());//创建邮件发送者地址
mailMessage.setFrom(from);//设置邮件消息的发送者
Address to = new InternetAddress(mailInfo.getToAddress());//创建邮件的接收者地址
mailMessage.setRecipient(Message.RecipientType.TO, to);//设置邮件消息的接收者
mailMessage.setSubject(mailInfo.getSubject());//设置邮件消息的主题
mailMessage.setSentDate(new Date());//设置邮件消息发送的时间
//MimeMultipart类是一个容器类，包含MimeBodyPart类型的对象
Multipart mainPart = new MimeMultipart();
MimeBodyPart messageBodyPart = new MimeBodyPart();//创建一个包含HTML内容的MimeBodyPart
//设置HTML内容
messageBodyPart.setContent(mailInfo.getContent(),"text/html; charset=utf-8");
mainPart.addBodyPart(messageBodyPart);
//存在附件
String[] filePaths = mailInfo.getAttachFileNames();
if (filePaths != null && filePaths.length > 0) {
for(String filePath:filePaths){
messageBodyPart = new MimeBodyPart();
File file = new File(filePath);
if(file.exists()){//附件存在磁盘中
FileDataSource fds = new FileDataSource(file);//得到数据源
messageBodyPart.setDataHandler(new DataHandler(fds));//得到附件本身并至入BodyPart
messageBodyPart.setFileName(file.getName());//得到文件名同样至入BodyPart
mainPart.addBodyPart(messageBodyPart);
}
}
}
//将MimeMultipart对象设置为邮件内容
mailMessage.setContent(mainPart);
Transport.send(mailMessage);//发送邮件
return true;
}catch (Exception e) {
e.printStackTrace();
}
return false;
}
}
三、创建邮件发送实现类（SendMail.java）
public class SendMail {
public static boolean sendHtmlMail(String title,String toAddress,String body) {
MailInfo mailInfo = new MailInfo();
mailInfo.setMailServerHost("smtp.exmail.qq.com");//服务器ip
mailInfo.setMailServerPort("465"); //服务器端口号
mailInfo.setValidate(true); //是否需要身份验证
mailInfo.setUsername(""); //登录邮件发送服务器的用户名
mailInfo.setPassword("");//发件人邮箱密码
mailInfo.setFromAddress(""); //发送者的邮件地址
mailInfo.setToAddress(toAddress);//邮件接收者地址
mailInfo.setSubject(title); //邮件主题
StringBuffer demo = new StringBuffer();
demo.append("<!DOCTYPE html>")
.append("<html lang=\"zh-CN\" xmlns=\"http://www.w3.org/1999/xhtml\">")
.append("<head>")
.append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">")

.append("html,body,div,p,ul,li,ol,dl,dt,dd,h1,h2,h3,h4,h5,h6,form,input,select,button,textarea,iframe,table,th,td,hr,em{margin:0;padding:0;}")
.append("body{ background:#edeff0; height:100%;}")
.append("body{ background:#edeff0; height:100%;}")
.append(".msg_container{ background:#fff; width:1200px; margin:40px auto 0; border:3px solid #4294cf; min-height:500px; padding:3px;}")
.append(".msg_container .msg-tit{ height:60px; background:#4294cf;}")
.append(".msg_container .msg-tit h3{ font:24px/60px \"Microsoft Yahei\";color:#fff; text-indent:30px;}")
.append(".msg_container .msg-cont{ padding:50px 20px 0;}")
.append(".msg_container .msg-cont h4{ font:16px/40px \"Microsoft Yahei\";}")
.append(".msg_container .msg-cont p{ font:14px/32px \"Microsoft Yahei\"; text-indent:30px;}")
.append(".msg_container .msg-prompt{ width:98%; margin:80px auto; border-top:1px solid #ddd; font:12px/28px \"Microsoft Yahei\";}")
.append(".msg_container .msg-prompt .prpt-cont{ padding:30px 0 0 20px;}")
.append(".msg_container .msg-prompt .sk-msgbl{ color:#007ebd;}")
.append(".msg_container .msg-cont tr{font-weight: normal;}")
.append(".msg_container .msg-cont td ,.msg_container .msg-cont th{border: 1px solid #ccc;box-sizing: content-box;padding: 10px;text-align:center;}")
.append("</style>")
.append("</head>")
.append("<body>")
.append("<div class=\"cms-container\">")
.append("<main class=\"main\">")
.append("<div class=\"inner-main\">")
.append("<div class=\"msg_container\">")
.append("<div class=\"msg-tit\"><h3>系统通知</h3></div>")
//组装内容
.append("<div class=\"msg-cont\">")
.append(body)
.append("</div>")
//组装内容
.append("<div class=\"msg-prompt\"><div class=\"prpt-cont\">本邮件由系统自动发送，请勿回复，祝您工作愉快！ <br/>意见反馈邮箱：<a href=\"javascript:;\" class=\"sk-msgbl\"></a><br/></div></div>")
.append("</div></div></main></div>")
.append("</body>")
.append("</html>");
mailInfo.setContent(demo.toString());
return SimpleMail.sendHtmlMail(mailInfo);
}
public static boolean sendTextMail(String title,String content,String toAddress) {
MailInfo mailInfo = new MailInfo();
mailInfo.setMailServerHost("smtp.exmail.qq.com");//服务器ip
mailInfo.setMailServerPort("465"); //服务器端口号
mailInfo.setValidate(true); //是否需要身份验证
mailInfo.setUsername(""); //登录邮件发送服务器的用户名
mailInfo.setPassword("");//发件人邮箱密码
mailInfo.setFromAddress(""); //发送者的邮件地址

mailInfo.setSubject(title); //邮件主题
mailInfo.setContent(content);//邮件内容
return SimpleMail.sendTextMail(mailInfo);
}
public static void test(){
System.out.println("测试");
}
}

p.put("mail.smtp.host", this.mailServerHost);
//p.put("mail.smtp.port", this.mailServerPort);
p.put("mail.smtp.auth", validate ? "true" : "false");
return p;
}
public String getMailServerHost() {
return mailServerHost;
}
public void setMailServerHost(String mailServerHost) {
this.mailServerHost = mailServerHost;
}
public String getMailServerPort() {
