1. 先定义发送邮件所需要的一些基本信息MailSenderInfo.java
package com.unj.mail_send2;
import java.io.File;
import java.util.List;
import java.util.Properties;
public class MailSenderInfo {
// 发送邮件的服务器的地址和端口，其实端口号可以不用指定
private String mailServerHost="smtp.qq.com";
private String mailServerPort = "25";
// 邮件发送者的地址
private String fromAddress="[email protected]";
// 邮件接收者的地址
private String toAddress="[email protected]";
// 登陆邮件发送服务器的用户名和密码
private String userName="[email protected]";
private String password="wahaha";
// 是否需要身份验证
private boolean validate = true;
// 邮件主题
private String subject="subject";
// 邮件的文本内容
private String content="hehe";
// 邮件附件的文件名
private String[] attachFileNames;
private List<File> fileList;
/**
* 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 void addFile(File file){
fileList.add(file);
}
//然后是一些get/set方法
}
2. 然后编写验证模块
package com.unj.mail_send2;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
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;
}
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
}
3. 最后是发送方法的编写，注意看加没加附件的差别
package com.unj.mail_send2;
import java.io.File;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
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;
public class SimpleMailSender {
/**
* 以文本格式发送邮件
*
* @param mailInfo
* 待发送的邮件的信息
*/
public boolean sendTextMail(MailSenderInfo mailInfo) {
// 判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties pro = 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(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.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());
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.getContent();
mailMessage.setText(mailContent);
// 发送邮件
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
/**
* 以HTML格式发送邮件
*
* @param mailInfo
* 待发送的邮件信息
*/
public boolean sendHtmlMail(MailSenderInfo mailInfo) {
// 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);
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.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 multPart = 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");
multPart.addBodyPart(html);
// ============添加附件操作=============/
List<File> list = mailInfo.getFileList();
if (list != null && list.size() > 0) {// 有附件
for (File f : list) {
MimeBodyPart mbp = new MimeBodyPart();
FileDataSource fds = new FileDataSource(f.getAbsolutePath()); // 得到数据源
mbp.setDataHandler(new DataHandler(fds));
mbp.setFileName(f.getName());
multPart.addBodyPart(mbp);
}
list.clear();
}
// ============添加附件操作=============/
// 将MiniMultipart对象设置为邮件内容
mailMessage.setContent(multPart);
// 发送邮件
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
public static void main(String[] args) {
SimpleMailSender mailSender = new SimpleMailSender();
MailSenderInfo mailInfo = new MailSenderInfo();
List<File> fileList = new ArrayList<File>();
fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/idl2wsdl.bat"));
fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/wsdl2java.bat"));
fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/wsdl2js.bat"));
fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/wsdl2soap.bat"));
mailInfo.setFileList(fileList);
if (mailSender.sendTextMail(mailInfo)) {
System.out.println("ok!");
}
if (mailSender.sendHtmlMail(mailInfo)) {
System.out.println("ok too!");
}
}
}
其实，发送文本邮件和html格式的邮件区别就在于
mailMessage.setText(mailContent);
mailMessage.setContent(a);
Multipart a = new MimeMultipart();
a.addBodyPart(b);
MimeBodyPart b = new MimeBodyPart();
b.setContent("xxx", "text/html; charset=utf-8");
