Java实现发送邮件demo

1.测试类

public class EmailTest {

  public static void main(String[] args) {

MailSenderInfo mailInfo = new MailSenderInfo();

SimpleMailSender simpleMailSender = new SimpleMailSender();

mailInfo.setContent("<a href='http://www.baidu.com' target='_blank'>HelloWorld!</a>");

mailInfo.setSubject("test");

mailInfo.setToAddress("123@qq.com");

boolean flag = simpleMailSender.sendDefHtmlMail(mailInfo);

System.out.println(flag);

}

}

2.MailSenderInfo 类 

public class MailSenderInfo {

// 发送邮件的服务器的协议 IP和端口
private String protocol = "Exchange";
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;
// 登录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;

private String remoteAddrIp;
/** */
/**
* 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.transport.protocol", this.protocol);
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;
}

public String getRemoteAddrIp() {
return remoteAddrIp;
}

public void setRemoteAddrIp(String remoteAddrIp) {
this.remoteAddrIp = remoteAddrIp;
}

}

3.SimpleMailSender类

public class SimpleMailSender {
/**
* 以文本格式发送邮件
* 
* @param mailInfo
*            待发送的邮件的信息
*/
public static boolean sendTextMail(MailSenderInfo mailInfo) {
// 判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
pro.setProperty("mail.smtp.localhost", mailInfo.getRemoteAddrIp());
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 static 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.s
be86
etSentDate(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);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}

public static boolean sendDefHtmlMail(MailSenderInfo mailInfo) {
mailInfo.setMailServerHost(Constants.EMAIL_SMTP_HOSTNAME);
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
mailInfo.setUserName(Constants.EMAIL_SERVERS_USERNAME);
mailInfo.setPassword(Constants.EMAIL_SERVERS_USERPASS);
mailInfo.setFromAddress(Constants.EMAIL_SERVERS_SENDER);
mailInfo.setFromAddress(mailInfo.getUserName()+Constants.EMAIL_SUFFIX);
return sendHtmlMail(mailInfo);
}

public static boolean sendDefTextMail(MailSenderInfo mailInfo) {
mailInfo.setMailServerHost(Constants.EMAIL_SMTP_HOSTNAME);
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
mailInfo.setUserName(Constants.EMAIL_SERVERS_USERNAME);
mailInfo.setPassword(Constants.EMAIL_SERVERS_USERPASS);
mailInfo.setFromAddress(Constants.EMAIL_SERVERS_SENDER);
mailInfo.setFromAddress(mailInfo.getUserName()+Constants.EMAIL_SUFFIX);
return sendTextMail(mailInfo);
}

}

4.Constans类

public class Constants {

//SMART邮件

/*public static final String EMAIL_SMTP_HOSTNAME = "mail.eetop.com";
public static final String EMAIL_SERVERS_USERNAME = "able9service";
public static final String EMAIL_SERVERS_SENDER = "service@able9.com";
public static final String EMAIL_SERVERS_USERPASS = "able9*3";*/

public static final String EMAIL_SMTP_HOSTNAME = "smtp.163.com";
public static final String EMAIL_SERVERS_USERNAME = "xxx";
public static final String EMAIL_SERVERS_SENDER = "xxx@163.com";
public static final String EMAIL_SERVERS_USERPASS = xxx";
public static final String EMAIL_SUFFIX = "@163.com";

}
