package com.autonavi.utils;import java.util.Properties;import javax.mail.MessagingException;import javax.mail.internet.MimeMessage;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.mail.javamail.JavaMailSenderImpl;import org.springframework.mail.javamail.MimeMessageHelper;import com.autonavi.constants.Constant;public class EmailUtils { private static final Logger logger = LoggerFactory.getLogger(EmailUtils.class); public static boolean sendHtmlMail(String subject,String content,String receiver){ boolean result = true; try{ JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); // 设定mail server senderImpl.setHost("smtp.abcdefg.com"); senderImpl.setPort(345); senderImpl.setUsername(Constant.email); // 根据自己的情况,设置发件邮箱地址 senderImpl.setPassword(Constant.email_password); // 根据自己的情况, 设置password senderImpl.setDefaultEncoding("UTF-8"); Properties prop = new Properties(); prop.put("mail.smtp.auth", "true"); // 将这个参数设为true，让服务器进行认证,认证用户名和密码是否正确 prop.put("mail.smtp.ssl.enable", "true"); prop.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); senderImpl.setJavaMailProperties(prop); // 建立邮件消息,发送简单邮件和html邮件的区别 MimeMessage mailMessage = senderImpl.createMimeMessage(); MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage); // 设置收件人，寄件人 messageHelper.setTo(receiver); messageHelper.setFrom(Constant.email); messageHelper.setSubject(subject); // true 表示启动HTML格式的邮件 messageHelper.setText(content,true); // 发送邮件 senderImpl.send(mailMessage); } catch (MessagingException e) { // TODO Auto-generated catch block result = false; logger.info("EmailUtils.method [sendHtmlMail]: email send result-" + result +",error message-" + e); } return result; }} |
以上设置中，有几个点需要注意：
第一点：
|
1
2
|
senderImpl.setUsername(Constant.email); senderImpl.setPassword(Constant.email_password); |
上面两个方法是用来设置发件的邮箱，邮箱地址要写全，如aba@abc.com。
如果设置得不对，会提示权限错误。
第二点：
|
1
|
senderImpl.setDefaultEncoding(“UTF-8”); |
这个一定记得设置，否则会邮件发出去会是下面这种结果。
第三点：
|

|
Properties prop = new Properties(); prop.put(“mail.smtp.auth”, “true”); prop.put(“mail.smtp.ssl.enable”, “true”); prop.put(“mail.smtp.socketFactory.class”, “javax.NET.ssl.SSLSocketFactory”); senderImpl.setJavaMailProperties(prop); |
一定要记得配置Properties，且上述配置缺一不可，如果没配置，大家会看见各种奇怪的异常。
1.3、邮件正文处理，使用HTML模版
下面的getHtmlStr()方法用来将待发送的内容处理为HTML模版。
- public static String getHtmlStr(JSONArray data,String receiver,int day){
- JSONObject json = data.getJSONObject(0);
- String title = json.getString("task_tittle");
- // NO.1、获取收件人名
- String receiverName = getEmailStr(receiver);
- // NO.2、获取邮件表格
- String emailTable = getTableStr(data);
- // NO.3、获取邮件时间
- String emailDate = Date2Str.getCurrentDate2();
- String html = "<html><head></head><body>"
- + "<p>" +receiverName+" 您好,</p>"
- + "<p> 生产日程-<font size="4" color="#FF0000" face="Verdana" >"+title+"</font>中的下列任务将于<font size="4" color="#FF0000" face="Verdana" >"+day+"</font>天后开始启动，请关注:</p>"
- + "<div style="padding-left:20px">"
- + "<table border="1px" cellspacing="0px" style="border-collapse:collapse">"
- + "<tr>"
- + "<td>任务名</td><td>启动时间</td><td>结束时间</td>"
- + "</tr>"
- + emailTable
- + "</table></div>"
- + "<p> 每项任务的详细情况,请登陆 "
- + "<a href="http://100.78.205.244:8080"><font size="4" color="#FF0000">项目综合管理&评价系统</font></a> 查看!</p>"
- + "<p>项目综合管理&评价系统</br>"+emailDate+"</p>"
- + "</body></html>";
- return html;
- }
应用改模版后，发出的邮件显示效果如下：
至于具体业务场景，你想定义什么样的模版都行。

如果运行过程中报上述异常，请再次核对收发邮件的邮箱账号是否有效。
3、总结
SpringBoot邮件发送主要是利用已封装好的两个jar包：mail-1.4.7.jar、spring-support-2.0.8.jar，使得配置邮件发送不再复杂。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
