邮件基本信息类
1、邮件信息类MailSenderInfo
package com.util.mail;
/**
* 发送邮件需要使用的基本信息
*/
import java.util.Properties;
public class MailSenderInfo {
// 发送邮件的服务器的IP和端口
private String mailServerHost;
private String mailServerPort = "25";
// 邮件发送者的地址
private String fromAddress;
// 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 = false;
// 邮件主题
private String subject;
// 邮件的文本内容
private String content;
// 邮件附件的文件名
private String[] attachFileNames;
/**
* 获得邮件会话属性
*/
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 boolean isValidate() {
return validate;
}
public void setValidate(boolean validate) {
this.validate = validate;
}
public String[] getAttachFileNames() {
return attachFileNames;
}
public void setAttachFileNames(String[] fileNames) {
this.attachFileNames = fileNames;
}
public String getFromAddress() {
return fromAddress;
}
public void setFromAddress(String fromAddress) {
this.fromAddress = fromAddress;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
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 getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String textContent) {
this.content = textContent;
}
} 2、用户密码类MyAuthenticator
package com.util.mail;
import javax.mail.*;
public class MyAuthenticator extends Authenticator{
String userName=null;
String password=null;
public MyAuthenticator(){
}
public MyAuthenticator(String username, String password) {
this.userName = username;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName, password);
}
} 3、以HTML格式发送邮件 SimpleMailSender
package com.util.mail;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
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;
/**
* 简单邮件（不带附件的邮件）发送器
*/
public class SimpleMailSender {
/**
* 以HTML格式发送邮件
* @param mailInfo 待发送的邮件信息
* @throws MessagingException
*/
public void sendHtmlMail(MailSenderInfo mailInfo) throws MessagingException{
// 判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
//如果需要身份认证，则创建一个密码验证器
if (mailInfo.isValidate()) {
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(pro,authenticator);
// 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.getFromAddress());
// 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());
// Message.RecipientType.TO属性表示接收者的类型为TO
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());
// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
Multipart mainPart = new MimeMultipart();
// 创建一个包含HTML内容的MimeBodyPart
BodyPart html = new MimeBodyPart();
// 设置HTML内容
html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");
mainPart.addBodyPart(html);
// 将MiniMultipart对象设置为邮件内容
mailMessage.setContent(mainPart);
// 发送邮件
Transport.send(mailMessage);
}
} 4、邮件工具类SentMailTool
package com.util.mail;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
import org.activiti.engine.impl.util.json.JSONObject;

try {

this.mailHost = properties.getProperty("mail.smtp.host");
this.mailPort = properties.getProperty("mail.smtp.port");
this.mailAuth =Boolean.parseBoolean(properties.getProperty("mail.smtp.auth"));
this.sender_username = properties.getProperty("mail.sender.username");
this.sender_password = properties.getProperty("mail.sender.password");
this.sender_nick = properties.getProperty("mail.sender.nick");
//设置邮件参数
mailInfo.setMailServerHost(this.mailHost);
mailInfo.setMailServerPort(this.mailPort);
mailInfo.setValidate(this.mailAuth);
mailInfo.setUserName(this.sender_username);
mailInfo.setPassword(this.sender_password);//您的邮箱密码
if(StringUtils.isNotBlank(this.sender_nick)){
mailInfo.setFromAddress(sender_nick+" <"+this.sender_username+">");
}else{
mailInfo.setFromAddress(this.sender_username);
}
} catch (IOException e) {
e.printStackTrace();
}
}
/**

* @Title: toSendHtmlMail
* @Description: 发送HTML格式的邮件
* @param mailAddress 接受邮箱地址

* @return
* @return: boolean
*/
public JSONObject toSendHtmlMail(String mailAddress,String title,String message){
JSONObject json=new JSONObject();
try {
mailInfo.setToAddress(mailAddress);
mailInfo.setSubject(title);
mailInfo.setContent(message);
//这个类主要来发送邮件
SimpleMailSender sms = new SimpleMailSender();
sms.sendHtmlMail(mailInfo);//发送html格式
json.put("result", true);
}catch (Exception e) {
e.printStackTrace();
json.put("message", getErrorMessasge(e.getMessage()));

}
return json;
}
/**

*/
private String getErrorMessasge(String message) {
Map<String,String> map=new HashMap<String,String>();
map.put("There are no DNS entries for the hostname, I cannot determine where to send this message", "检索不到接收方域名的邮件解析（MX记录）和域名解析（A记录）");

return message;

}
5、 发送邮件服务器配置文件portlet.properties
#邮件服务器配置
#smtp 服务器
mail.smtp.host=smtp.163.com
#身份验证,默认true
mail.smtp.auth=true
#端口号
mail.smtp.port=25
#发送者的邮箱用户名
mail.sender.username=longchengguoke@163.com
#发送者的邮箱密码
mail.sender.password=123456asd
#发送者想要显示的昵称,选填
mail.sender.nick=Mr.cheng6、备注：上边这个邮件服务器配置可以直接使用，如果密码不对可以找我要最新的授权码，也可以自己申请163邮箱服务器
