本文参考spring官网email接口文档所写。

1：添加相关依赖
<!-- /artifact/org.springframework.boot/spring-boot-starter-mail --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId><version>2.1.6.RELEASE</version></dependency>
2：先建一个邮箱收件人model
package com.dev.model.email;import java.io.Serializable;/*** Created on -08-02 16:16.** @author zgq7*/public class EmailModel implements Serializable {/*** 收件人姓名**/private String recieverName;/*** 收件人邮箱地址**/private String recieverEmailAddress;/*** 邮件主题**/private String emailTheme;/*** 邮件内容**/private String emailContent;public String getRecieverName() {return recieverName;}public void setRecieverName(String recieverName) {this.recieverName = recieverName;}public String getRecieverEmailAddress() {return recieverEmailAddress;}public void setRecieverEmailAddress(String recieverEmailAddress) {this.recieverEmailAddress = recieverEmailAddress;}public String getEmailTheme() {return emailTheme;}public void setEmailTheme(String emailTheme) {this.emailTheme = emailTheme;}public String getEmailContent() {return emailContent;}public void setEmailContent(String emailContent) {this.emailContent = emailContent;}}
3：编写一个邮箱工具类
package com.dev.utils.email;import com.dev.model.email.EmailModel;import org.jetbrains.annotations.NotNull;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.mail.MailException;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.javamail.JavaMailSenderImpl;import org.springframework.mail.javamail.MimeMessageHelper;import org.springframework.mail.javamail.MimeMessagePreparator;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.internet.MimeMessage;import java.time.LocalDateTime;import java.time.format.DateTimeFormatter;/*** Created on -08-02 16:06.** @author zgq7*/public class MailSendUtils {private static final Logger logger = LoggerFactory.getLogger(MailSendUtils.class);/*** 发送者地址**/private static String posterAdress = "xxx@";/*** 发送者姓名**/private static final String posterName = "xxx";@Autowiredprivate JavaMailSender javaMailSender;@Autowiredprivate JavaMailSenderImpl javaMailSenderImpl;/*** 文本发送**/public void sendEmailAsText(final EmailModel emailModel) {MimeMessagePreparator mimeMessagePreparator = mimeMessage -> {mimeMessage.setFrom(posterAdress);mimeMessage.setRecipients(Message.RecipientType.TO, emailModel.getRecieverEmailAddress());mimeMessage.setText("<html><body>"+ "hello：" + emailModel.getRecieverName()+ "<br>" + "msg：" + emailModel.getEmailContent()+ "<br>" + "from :" + posterName+ "</body></html>");};try {this.javaMailSender.send(mimeMessagePreparator);logger.info("邮箱已返送至[{}]邮箱！", emailModel.getRecieverName());} catch (MailException e) {logger.error("邮箱异常：{}", e);}}/*** html 网页发送* 该方法为同步方法**/public void sendEmailAsSysExceptionHtml(final EmailModel emailModel) {MimeMessage mimeMessage = javaMailSenderImpl.createMimeMessage();MimeMessageHelper mimeMessageHelper;try {mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);mimeMessageHelper.setFrom(posterAdress);mimeMessageHelper.setTo(emailModel.getRecieverEmailAddress());mimeMessageHelper.setText("<!DOCTYPE html>\n" +"<html>\n" +"\t<head>\n" +"\t\t<meta charset=\"UTF-8\">\n" +"\t\t<title></title>\n" +"\t</head>\n" +"\t<style>\n" +"\t\tbody,\n" +"\t\ttable,\n" +"\t\ttbody,\n" +"\t\ttr {\n" +"\t\t\tbackground-color: aquamarine;\n" +"\t\t\tbackground-size: 100%;\n" +"\t\t}\n" +"\t</style>\n" +"\n" +"\t<body>\n" +"\t\t<table border=\"solid 2 px\" align=\"center\" style=\"text-align: center;\">\n" +"\t\t\t<tbody>\n" +"\t\t\t\t<tr>\n" +"\t\t\t\t\t<td width=\"200px\" bgcolor=\"coral\">时间</td>\n" +"\t\t\t\t\t<td width=\"80%\" bgcolor=\"azure\">" + LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")) + "</td>\n" +"\t\t\t\t</tr>\n" +"\t\t\t\t<tr>\n" +"\t\t\t\t\t<td width=\"200px\" bgcolor=\"coral\">信息</td>\n" +"\t\t\t\t\t<td width=\"80%\" bgcolor=\"azure\">" + "测试" + "</td>\n" +"\t\t\t\t</tr>\n" +"\t\t\t\t<tr>\n" +"\t\t\t\t\t<td width=\"200px\" bgcolor=\"coral\">堆栈</td>\n" +"\t\t\t\t\t<td width=\"80%\" bgcolor=\"azure\" style=\"text-align: left;\">" + emailModel.getEmailContent() + "</td>\n" +"\t\t\t\t</tr>\n" +"\t\t\t</tbody>\n" +"\t\t</table>\n" +"\t</body>\n" +"\n" +"</html>", true);this.javaMailSender.send(mimeMessage);logger.info("邮箱已返送至[{}]邮箱！", emailModel.getRecieverName());} catch (MessagingException e) {e.printStackTrace();} catch (MailException e) {logger.error("邮箱异常：{}", e);}}}
notice3.1:可自行设置文本发送api、html发送api、图片发送api等。我的工具包中只写了文本发送和html发送两种格式的api。
4：在IOC中注册EmailUtils的bean
package com.dev.config;import com.dev.utils.email.MailSendUtils;
/*** Created by zgq7 on /6/6.* 注册一些bean进入ioc**/@Configurationpublic class BeanRegistryCenterConfig {
/*** 邮箱工具类 bean 注册**/@Beanpublic MailSendUtils mailSendUtils() {return new MailSendUtils();}}
5：在Application.xml中添加一下信息
spring.mail.host=spring.mail.port=587spring.mail.username=你的qq@spring.mail.password=xxxxx spring.mail.protocol=smtpspring.mail.default-encoding=UTF-8
notice1：spring.mail.usernam，是你的qq邮箱地址
notice2：spring.mail.password，不要用真正的qq邮箱密码，而是qq邮箱第三方服务授权码
下面是获取qq邮箱第三方服务授权码的操步骤：
5.1：登录qq邮箱，进入首页，点击设置按钮
5.2：点击账户设置
并拉到最下面点击我圈中的开启按钮
然后会弹出一个小框提示你发信息，发就行了，发送之后点击验证会收到授权码
除了spring.mail.username、spring.mail.password 两项要换成自己的 ，其他的和我一样就行；
6：进行邮件发送测试
6.1：文本发送测试
/*** Java Mail 文本发送**/@Testpublic void EmaiTest() {EmailModel emailModel = new EmailModel();emailModel.setEmailTheme("测试");emailModel.setRecieverName("测试");emailModel.setEmailContent("测试");emailModel.setRecieverEmailAddress("xxx@");mailSendUtils.sendEmailAsText(emailModel);}
发送成功后：
目标邮箱收到的邮件：
6.2：html发送测试
/*** Java Mail 网页发送**/@Testpublic void EmailTest2() throws MessagingException, InterruptedException {EmailModel emailModel = new EmailModel();emailModel.setEmailTheme("测试");emailModel.setRecieverName("测试");emailModel.setEmailContent("测试");emailModel.setRecieverEmailAddress("xxx@");mailSendUtils.sendEmailAsSysExceptionHtml(emailModel);}
目标邮箱收到的邮件：
这个展示效果可以自己设置。
7：注意点：发送邮件者的邮箱地址为qq邮箱，否则会QQ邮箱认证报错。而接收者邮箱可以为其他的邮箱，如企业邮箱、网易邮箱等。
看过的点个赞好不好啊。
