使用JavaMail发送邮件
闲来没事研究了一下javamail发邮件。虽然比Spring框架的mail复杂一些，但是还是值得研究一下的。
mail.jar和本程序的jar包都会在附件中上传，供大家使用学习。
第一个类，用于密码验证，注意看注释，很重要。
package com.xian.gmail;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
/**
* JavaMail的密码验证器
* @author 贾小仙
*/
public class MyAuther extends Authenticator{
String userName=null;
String password=null;
public MyAuther() {
}
public MyAuther(String userName, String password) {
this.userName = userName;
this.password = password;
}
//getPasswordAuthentication 名字必须对。 源码中是return null。相当于重写
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName,password);
}
}
第二个类是实体类，做一些基本参数处理
package com.xian.gmail;
public class MailSenderInfo {
// 发送邮件的服务器的IP和端口
private String host;
private String port="25";
// 邮件发送者的地址
private String address;
// 邮件接收者的地址
private String toAddress;
// 登陆邮件发送服务器的用户名和密码
private String userName;
private String password;
// 是否需要身份验证
private Boolean Validate=true;
// 邮件主题
private String subJect;
// 邮件的文本内容
private String context;
// 邮件附件的文件名
private String[] fileName;
/**
* 获得邮件会话属性
*/
/* public Properties getProperties(){
Properties pro=new Properties();
pro.put("mail.smtp.host",this.host);
pro.put("mail.smtp.port", this.port);
pro.put("mail.smtp.auth", Validate ? "true":"false");
return pro;
}*/
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public String getPort() {
return port;
}
public void setPort(String port) {
this.port = port;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
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 getContext() {
return context;
}
public void setContext(String context) {
this.context = context;
}
public String[] getFileName() {
return fileName;
}
public void setFileName(String[] fileName) {
this.fileName = fileName;
}
}
第三个类就是实现类了，发送邮件的具体操作都在这里
package com.xian.gmail;
import java.util.Date;
import java.util.Properties;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
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.Address;
import javax.mail.Multipart;
/**
* 简单邮件（不带附件的邮件）发送器
*/
public class MailSender {
public boolean sendTextMail(MailSenderInfo mailInfo){
// 判断是否需要身份认证
MyAuther authenticator = null;
if (mailInfo.IsValidate()) {
// 如果需要身份认证，则创建一个密码验证器
authenticator = new MyAuther(mailInfo.getUserName(), mailInfo.getPassword());
}
Properties pro=getProperties(mailInfo);
// 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(pro,authenticator);
try {
// 根据session创建一个邮件消息
Message mailMessage = new MimeMessage(sendMailSession);
// 创建邮件发送者地址
Address from = new InternetAddress(mailInfo.getAddress());
// 设置邮件消息的发送者
mailMessage.setFrom(from);
// 创建邮件的接收者地址，并设置到邮件消息中
Address to = new InternetAddress(mailInfo.getToAddress());
mailMessage.setRecipient(Message.RecipientType.TO,to);
// 设置邮件消息的主题
mailMessage.setSubject(mailInfo.getSubJect());
// 设置邮件消息发送的时间
mailMessage.setSentDate(new Date());
// 设置邮件消息的主要内容
String mailContent = mailInfo.getContext();
mailMessage.setText(mailContent);
// 发送邮件
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
/**
* 用HTML格式发送邮件
* @param mailInfo 邮件基本信息
* @return 成功
* @author 贾小仙
*/
public boolean sendHtmlMail(MailSenderInfo mailInfo){
MyAuther auth=null;
if(mailInfo.IsValidate()){
auth=new MyAuther(mailInfo.getUserName(), mailInfo.getPassword());
}
Properties pro=getProperties(mailInfo);
try {
Session sendMailSession = Session.getDefaultInstance(pro, auth);
Message msg = new MimeMessage(sendMailSession);
Address address = new InternetAddress(mailInfo.getAddress());
msg.setFrom(address);
Address toAddress=new InternetAddress(mailInfo.getToAddress());
msg.setRecipient(Message.RecipientType.TO, toAddress);
msg.setSubject(mailInfo.getSubJect());
msg.setSentDate(new Date());
// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
Multipart mailPart=new MimeMultipart();
BodyPart html =new MimeBodyPart();
html.setContent(mailInfo.getContext(),"text/html;charset=utf-8");
mailPart.addBodyPart(html);
// 将MiniMultipart对象设置为邮件内容
msg.setContent(mailPart);
// 发送邮件
Transport.send(msg);
return true;
} catch (MessagingException e) {
// TODO: handle exception
e.printStackTrace();
}
return false;
}
public Properties getProperties(MailSenderInfo mailInfo){
Properties pro = new Properties();
String mailName=mailInfo.getUserName();
String mailType=mailName.substring(mailName.indexOf('@')+1, mailName.length());
if(mailType.indexOf("gmail")!=-1){
pro.setProperty("mail.smtp.host", "smtp.gmail.com");
pro.setProperty("mail.smtp.port", "465");
pro.setProperty("mail.smtp.auth", "true");
pro.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
pro.setProperty("mail.smtp.socketFactory.fallback", "false");
pro.setProperty("mail.smtp.socketFactory.port", "465");
pro.setProperty("mail.smtp.ssl", "true");
}
if(mailType.equals("163.com")||mailType.equals("sohu.com")||mailType.equals("126.com")){
String mailserver = "smtp."+mailType;
pro.setProperty("mail.smtp.host", mailserver);
pro.setProperty("mail.smtp.port", "25");
pro.setProperty("mail.smtp.auth", "true");
}
if (mailType.indexOf("sina")!=-1){
pro.setProperty("mail.smtp.host", "smtp.sina.com.cn");
pro.setProperty("mail.smtp.port", "25");
pro.setProperty("mail.smtp.auth", "true");
}
return pro;
}
}
第四个类 相当于一个接口类，用来传参数。
package com.xian.gmail;
public class Send {
/**
* 发送邮件所需要的参数 用户名，密码，收件人，主题，内容
* @param userName
* @param password
* @param toAddress
* @param subJect
* @param context
*/
public static void sendMail(String userName,String password,String toAddress,String subJect,String context){
MailSenderInfo mailInfo=new MailSenderInfo();
mailInfo.setUserName(userName);
mailInfo.setPassword(password);
mailInfo.setAddress(userName);
mailInfo.setToAddress(toAddress);
mailInfo.setSubJect(subJect);
mailInfo.setContext(context);
MailSender send=new MailSender();
//这个类主要来发送邮件
boolean result=send.sendTextMail(mailInfo);//发送文体格式
if(result){
System.out.println("发送成功");
}else{
System.out.println("发送失败");
}
};
}
第五个类 具体调用
import com.xian.gmail.Send;
public class GoMail extends Send{
public void main(){
}
public void main(String[] args) {
Send.sendMail("*****@163.com", "*****", "***@163.com", "你好呀", "Can you speek English?Mr 小贾");
}
}
简单的实现，通用126,163，sohu,sina,gmail。 qq忘记了自己添加
