1.先引入maven依赖，在pom.xml文件中添加：
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-mail -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
<version>2.1.1.RELEASE</version>
</dependency>
注意里面我使用的是log4j日志对信息进行记录，不懂得同学们可以点击此处快速学习
2.配置application.peroperties文件：
spring.mail.host=smtp.163.com
spring.mail.username=输入自己的163邮箱
spring.mail.password=输入自己的邮箱密码
spring.mail.port=25
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8
3.创建一个测试类，注意不会单元测试的可以点击此处

// cid为固定写法，imageId指定一个标识
sb.append("<img src='https://www.google.com/images/branding/googlelogo/2x/googlelogo_light_color_272x92dp.png'></body>");
sb.append("</html>");
// 启用html
mimeMessageHelper.setText(sb.toString(), true);
// 设置imageId
FileSystemResource img = new FileSystemResource(new File("D:/壁纸/21.jpg"));
mimeMessageHelper.addInline("imageId", img);
// 发送邮件
mailSender.send(mimeMessage);
logger.info("邮件已经从"+postCount+"->发送到账户"+receiver+",发送内容为："+img);
System.out.println("邮件已发送");
}
/**

@Test

sb.append("<body><h1>spring 邮件测试</h1><p>hello!this is spring mail annex test</p></body>");

FileSystemResource file = new FileSystemResource(new File("D:/简历/个人简历 朱旭.docx"));

}
}
具体更多的java有邮件设置可以参考此处,不过个人认为上面提到的这些已经可以满足大部分人的需求了
