SpringBoot 发送Email

首先导入依赖坐标

在pom.xml的<dependencies/>标签中添加如下依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

其次配置邮件信息

在application.properties配置文件信息中添加邮件配置信息

#配置邮箱信息
spring.mail.username=自己的邮箱
spring.mail.password=授权码
#发送邮件服务器
#这里我使用的163.com发送
spring.mail.host=smtp.163.com

实现代码

一、简单文本邮件发送

//按照类型配置
@Autowired(required = false)
private JavaMailSenderImpl javaMailSender;

   //发送简单邮件
   @Test
   void show1() {
   //1.创建邮件对象
   SimpleMailMessage simpleMailMessage =   new SimpleMailMessage();
   //2.设置信息
   simpleMailMessage.setSubject("标题");
   simpleMailMessage.setText("正文内容");
   simpleMailMessage.setFrom("发送方的邮箱");
   simpleMailMessage.setTo("接收方的邮箱");
   //3.发送邮件
   javaMailSender.send(simpleMailMessage);
   System.out.println("发送成功");
 }

二、复杂附件邮件发送

//按照类型配置
@Autowired(required = false)
private JavaMailSenderImpl javaMailSender;    
   //发送复杂邮件
   @Test
   void show2()throws Exception {
   //1.创建邮件对象
   MimeMessage mimeMessage = javaMailSender.createMimeMessage();
   //2.创建MimeMessageHelper
   MimeMessageHelper mimeMessageHelper =  new MimeMessageHelper(mimeMessage,true);
   //3.设置信息
   mimeMessageHelper.setSubject("标题");
   mimeMessageHelper.setText("文本<span style='color:red'>颜色样式</span>",true);
   mimeMessageHelper.addAttachment("文件名称",new File("附件地址"));
   mimeMessageHelper.setFrom("发送方的邮箱");
   mimeMessageHelper.setTo("接受方的邮箱");
   //4.发送邮件
   javaMailSender.send(mimeMessage);
}

注：

邮件收发核心类

JavaMailSenderImpl

封装简单的邮件内容

SimpleMailMessage

封装复杂的邮件内容

MimeMessage

MimeMessageHelper
