java发送邮件带url、html

大家好，又见面了，我是你们的朋友全栈君。

代码也是在网上扒的，自己用到了也整理了下方便以后再用。

创建一个密码验证器类

package com.mail.test;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class MailAuthenticator extends Authenticator {
	
	public MailAuthenticator(String userName,String userPwd){
		this.userAccout = userName;
		this.userPassword = userPwd;
	}
	
	private String userAccout;
	private String userPassword;
	public String getUserAccout() {
		return userAccout;
	}
	public void setUserAccout(String userAccout) {
		this.userAccout = userAccout;
	}
	public String getUserPassword() {
		return userPassword;
	}
	public void setUserPassword(String userPassword) {
		this.userPassword = userPassword;
	}
	
	
	@Override
	protected PasswordAuthentication getPasswordAuthentication() {
		// TODO Auto-generated method stub
		return new PasswordAuthentication(userAccout, userPassword);
	}
}

邮箱实体类：

package com.mail.test;

import java.util.Properties;

public class MainInfo {
	// 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 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;
	} 
}

邮件发送类：

package com.mail.test;

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.internet.AddressException;
import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMultipart;

public class MailSender {

	/**

	 * @title sendMailText
	 * @description  发送纯文本形式邮件
	 * @date 2016-4-26 下午11:13:06
	 * @param mainInfo
	 * @return boolean
	 */
	public boolean sendMailText(MainInfo mainInfo) {
		Properties props = mainInfo.getProperties();
		MailAuthenticator mailauthenticator = null;
		if (mainInfo.isValidate()) {
			// 如果需要身份认证，则创建一个密码验证器
			mailauthenticator = new MailAuthenticator(mainInfo.getFromAddress(),
					mainInfo.getPassword());
		}
		Session sendMailSession = Session.getDefaultInstance(props,
				mailauthenticator);
		Message sendMailMessage = new MimeMessage(sendMailSession);
		try {
			Address from = new InternetAddress(mainInfo.getFromAddress());
			sendMailMessage.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(mainInfo.getToAddress());
			sendMailMessage.setRecipient(Message.RecipientType.TO, to);
			// 设置邮件消息的主题
			sendMailMessage.setSubject(mainInfo.getSubject());
			// 设置邮件消息发送的时间
			sendMailMessage.setSentDate(new Date());
			// 设置邮件消息的主要内容
			sendMailMessage.setText(mainInfo.getContent());
			// 发送邮件
			Transport.send(sendMailMessage);
			return true;
		} catch (AddressException e) {
			// TODO Auto-generated catch block
			System.out.println("邮件地址有误。。");
			e.printStackTrace();
			return false;
		} catch (MessagingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			return false;
		}
	}

	/**
	 * 
	 * @title sendMailHtml
	 * @description  发送带有html的邮件
	 * @date 2016-4-26 下午11:13:26
	 * @param mainInfo
	 * @return boolean
	 */
	public boolean sendMailHtml(MainInfo mainInfo) {
		Properties props = mainInfo.getProperties();
		MailAuthenticator mailauthenticator = null;
		if (mainInfo.isValidate()) {
			// 如果需要身份认证，则创建一个密码验证器
			mailauthenticator = new MailAuthenticator(mainInfo.getFromAddress(),
					mainInfo.getPassword());
		}
		Session sendMailSession = Session.getDefaultInstance(props,
				mailauthenticator);
		Message sendMailMessage = new MimeMessage(sendMailSession);

			sendMailMessage.setRecipient(Message.RecipientType.TO, to);
			
			// 设置邮件消息的主题
			sendMailMessage.setSubject(mainInfo.getSubject());
			// 设置邮件消息发送的时间
			sendMailMessage.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(mainInfo.getContent(), "text/html; charset=utf-8");
			mainPart.addBodyPart(html);
			// 将MiniMultipart对象设置为邮件内容
			sendMailMessage.setContent(mainPart);
			// 发送邮件
			Transport.send(sendMailMessage);
			return true;
		} catch (AddressException e) {
			System.out.println("邮件地址有误。。");
			e.printStackTrace();
			return false;
		} catch (MessagingException e) {
			e.printStackTrace();
			return false;
		}
	}
}

组织发送内容，包含url、html，测试发送：

package com.mail.test;

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;

public class MailTest {

	public static void main(String[] args) {
		try {
			MailSender sender  = new MailSender();
			MainInfo mainInfo = new MainInfo();
			mainInfo.setMailServerHost("smtp.163.com");  //imap.exmail.qq.com
			mainInfo.setMailServerPort("25");
			mainInfo.setUserName("烦烦烦");
			mainInfo.setFromAddress("*******");
			mainInfo.setPassword("*******");
			mainInfo.setToAddress("*******");
			mainInfo.setSubject("测试内容标题");
			StringBuffer url = new StringBuffer();
			url.append("http://locahost:8080");
			url.append("noa");
			url.append("/reportFindPassword/updatePassword.action?");
			url.append("employeeCode=123456");
			url.append("&employeeName="+URLEncoder.encode("发送邮件测试", "UTF-8"));
			url.append("&pemployeeCode=123456");
			url.append("&pemployeeName="+URLEncoder.encode("哈哈", "UTF-8"));
			url.append("&email=*******@***.com");
			url.append("&dateTime=20160418162538");
			StringBuffer content = new StringBuffer();
			content.append("<div><div style='margin-left:4%;'>");
			content.append("<p style='color:red;'>");
			content.append("啊啊啊(123456)您好：</p>");
			content.append("<p style='text-indent: 2em;'>您正在使用密码找回功能，请点击下面的链接完成密码找回。</p>");
			content.append("<p style='text-indent: 2em;display: block;word-break: break-all;'>");
			content.append("链接地址：<a style='text-decoration: none;' href='"+url.toString()+"'>"+url.toString()+"</a></p>");
			content.append("</div>");
			content.append("<ul style='color: rgb(169, 169, 189);font-size: 18px;'>");
			content.append("<li>为了保障您帐号的安全，该链接有效期为12小时。</li>");
			content.append("<li>该链接只能使用一次，请周知。</li>");
			content.append("<li>如果该链接无法点击，请直接复制以上网址到浏览器地址栏中访问。</li>");
			content.append("<li>请您妥善保管，此邮件无需回复。</li>");
			content.append("</ul>");
			content.append("</div>");
			mainInfo.setContent(content.toString());
			mainInfo.setValidate(true);
			sender.sendMailHtml(mainInfo);
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
	}

}

其中链接中包含的中文做URL转码，

最后的邮件为：

java发送邮件带url、html

此类邮件URL需要做校验，如果链接中只包含一个标示，则只对当前标示加密，如果所有参数都暴露在地址栏中可以将所有参数拼起来用MD5或者其他方式加密后存放在该URL中，例如为validateCode，此次也要对validateCode的值做encode转换，不然特殊符号在URL中会自动转换，之后只对validateCode校验即可知道该链接是否正确。
