import java.util.List;public interface IEmailService {/*** 发送简单文本邮件*/void sendSimpleMail(String receiveEmail, String subject, String content);/*** 发送HTML格式的邮件*/void sendHtmlMail(String receiveEmail, String subject, String emailContent) throws MessagingException;/*** 发送包含附件的邮件*/void sendAttachmentsMail(String receiveEmail, String subject, String emailContent, ListString filePathList) throws MessagingException; } 4、创建IEmailService接口的实现类EmailService.java 文件 package com.springboot.email.email.service.impl;import com.springboot.email.email.service.IEmailService; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service;import javax.annotation.Resource; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import java.io.File; import java.util.List; Service public class EmailServiceImpl implements IEmailService {Resourceprivate JavaMailSender mailSender;Value(${spring.mail.username})private String fromEmail;/*** 发送简单文本邮件*/public void sendSimpleMail(String receiveEmail, String subject, String content) {SimpleMailMessage message new SimpleMailMessage();message.setFrom(fromEmail);message.setTo(receiveEmail);message.setSubject(subject);message.setText(content);mailSender.send(message);}/*** 发送Html格式的邮件*/public void sendHtmlMail(String receiveEmail,String subject,String emailContent) throws MessagingException{init(receiveEmail, subject, emailContent, mailSender, fromEmail);}public static void init(String receiveEmail, String subject, String emailContent, JavaMailSender mailSender, String fromEmail) throws MessagingException {MimeMessage message mailSender.createMimeMessage();MimeMessageHelper helpernew MimeMessageHelper(message,true);helper.setFrom(fromEmail);helper.setTo(receiveEmail);helper.setSubject(subject);helper.setText(emailContent,true);mailSender.send(message);}/*** 发送包含附件的邮件*/public void sendAttachmentsMail(String receiveEmail, String subject, String emailContent, ListString filePathList) throws MessagingException {MimeMessage message mailSender.createMimeMessage();//带附件第二个参数trueMimeMessageHelper helper new MimeMessageHelper(message, true);helper.setFrom(fromEmail);helper.setTo(receiveEmail);helper.setSubject(subject);helper.setText(emailContent, true);//添加附件资源for (String item : filePathList) {FileSystemResource file new FileSystemResource(new File(item));String fileName item.substring(item.lastIndexOf(File.separator));helper.addAttachment(fileName, file);}//发送邮件mailSender.send(message);} } 5、新建邮件发送模板 email.html !DOCTYPE html html head langenmeta charsetUTF-8/title/titlestyletd {border: black 1px solid;}/style /head body h1工资条/h1 table styleborder: black 1px solid;width: 750pxtheadtd序号/tdtd姓名/tdtd基本工资/tdtd在职天数/tdtd奖金/tdtd社保/tdtd个税/tdtd实际工资/td/theadtbodytrtd${salary.index}/tdtd${salary.name}/tdtd${salary.baseSalary}/tdtd${salary.inDays}/tdtd${salary.reward}/tdtd${salary.socialSecurity}/tdtd${salary.tax}/tdtd${salary.actSalary}/td/tr/tbody /table /body /html 6、新建测试类主要代码如下 /*** 测试简单文本文件*/ Test public void EmailTest() {emailService.sendSimpleMail(hgmyzoutlook.com, 测试邮件, springboot 邮件测试); }Test public void HtmlEmailTest() throws MessagingException {String receiveEmail hgmyzoutlook.com;String subject Spring Boot 发送Html邮件测试;String emailContent h2您好/h2p这里是一封Spring Boot 发送的邮件祝您天天开心img srchttps://p3.toutiaoimg.com/origin/tos-cn-i-qvj2lq49k0/a43f0608912a4ecfa182084e397e4b81?frompc width500 height300 //p a hrefhttps://programmerblog.xyz titleIT技术分享设社区 targer_blankIT技术分享设社区/a;emailService.sendHtmlMail(receiveEmail, subject, emailContent); }Test public void templateEmailTest() throws IOException, TemplateException, MessagingException {String receiveEmail hgmyzoutlook.com;String subject Spring Boot 发送Templete邮件测试;//添加动态数据替换模板里面的占位符SalaryVO salaryVO new SalaryVO(1, 小明, 2, 9000.00, 350.06, 280.05, 350.00, 7806.00);Template template freeMarkerConfigurer.getConfiguration().getTemplate(email.html);//将模板文件及数据渲染完成之后转换为html字符串MapString, Object model new HashMap();model.put(salary, salaryVO);String templateHtml FreeMarkerTemplateUtils.processTemplateIntoString(template, model);emailService.sendHtmlMail(receiveEmail, subject, templateHtml); }Test public void emailContailAttachmentTest() throws IOException, TemplateException, MessagingException {String receiveEmail hgmyzoutlook.com;String subject Spring Boot 发送包含附件的邮件测试;//添加动态数据替换模板里面的占位符SalaryVO salaryVO new SalaryVO(1, 小王, 2, 9000.00, 350.06, 280.05, 350.00, 7806.00);Template template freeMarkerConfigurer.getConfiguration().getTemplate(email.html);//将模板文件及数据渲染完成之后转换为html字符串MapString, Object model new HashMap();model.put(salary, salaryVO);String templateHtml FreeMarkerTemplateUtils.processTemplateIntoString(template, model);ListString fileList new ArrayList();fileList.add(F:\\邮件测试.docx);fileList.add(F:\\5.png);fileList.add(F:\\db.jpg);emailService.sendAttachmentsMail(receiveEmail, subject, templateHtml, fileList); } 7、效果截图 简单文版邮件                 html文件                 包含附件的邮件                 Gitee地址https://gitee.com/hgm1989/springboot-email.git
