1：相关依赖
<!-- https://mvnrepository.com/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：邮箱收件人model
package com.dev.model.email; import java.io.Serializable; /** * Created on 2019-08-02 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：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 2019-08-02 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@qq.com"; /** * 发送者姓名 **/ private static final String posterName = "xxx"; @Autowired private JavaMailSender javaMailSender; @Autowired private 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> " + "<html> " + " <head> " + " <meta charset="UTF-8"> " + " <title></title> " + " </head> " + " <style> " + " body, " + " table, " + " tbody, " + " tr { " + " background-color: aquamarine; " + " background-size: 100%; " + " } " + " </style> " + " " + " <body> " + " <table border="solid 2 px" align="center" style="text-align: center;"> " + " <tbody> " + " <tr> " + " <td width="200px" bgcolor="coral">时间</td> " + " <td width="80%" bgcolor="azure">" + LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")) + "</td> " + " </tr> " + " <tr> " + " <td width="200px" bgcolor="coral">信息</td> " + " <td width="80%" bgcolor="azure">" + "测试" + "</td> " + " </tr> " + " <tr> " + " <td width="200px" bgcolor="coral">堆栈</td> " + " <td width="80%" bgcolor="azure" style="text-align: left;">" + emailModel.getEmailContent() + "</td> " + " </tr> " + " </tbody> " + " </table> " + " </body> " + " " + "</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：注册EmailUtils的bean
package com.dev.config; import com.dev.utils.email.MailSendUtils;
/** * Created by zgq7 on 2019/6/6. * 注册一些bean进入ioc * */ @Configuration public class BeanRegistryCenterConfig {
/** * 邮箱工具类 bean 注册 **/ @Bean public MailSendUtils mailSendUtils() { return new MailSendUtils(); } }
5：Application.properties配置
spring.mail.host=smtp.qq.com spring.mail.port=587 spring.mail.username=你的qq@qq.com spring.mail.password=xxxxx spring.mail.protocol=smtp spring.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：邮件发送测试
6.1：文本发送测试
/** * Java Mail 文本发送 **/ @Test public void EmaiTest() { EmailModel emailModel = new EmailModel(); emailModel.setEmailTheme("测试"); emailModel.setRecieverName("测试"); emailModel.setEmailContent("测试"); emailModel.setRecieverEmailAddress("xxx@qq.com"); 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 **/ @Test public void EmailTest2() throws MessagingException, InterruptedException { EmailModel emailModel = new EmailModel(); emailModel.setEmailTheme("测试"); emailModel.setRecieverName("测试"); emailModel.setEmailContent("测试"); emailModel.setRecieverEmailAddress("xxx@qq.com"); 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。
