一、创建项目导入依赖：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
二、发送邮件：
1）
spring:
mail:
host: smtp.163.com
username: 123123@163.com
password: onmhhhhovd
default-encoding: utf-8
2）简单邮件发送：
@Autowired private JavaMailSender sender; @Test public void sendMail(){ SimpleMailMessage mailMessage = new SimpleMailMessage(); mailMessage.setSubject("测试邮件主题"); mailMessage.setText("测试邮件内容"); mailMessage.setFrom("15968195@163.com"); mailMessage.setTo("47117@qq.com"); sender.send(mailMessage); }
3）带HTML邮件：
@Autowired private JavaMailSender sender; @Test public void sendMail1() throws MessagingException { MimeMessage message = sender.createMimeMessage(); MimeMessageHelper mailMessage = new MimeMessageHelper(message,true); mailMessage.setSubject("测试邮件主题"); mailMessage.setText("<a href=‘http://www.baidu.com‘>点击跳转百度</a>",true); mailMessage.setFrom("159195@163.com"); mailMessage.setTo("4755@qq.com"); sender.send(message); }
4）带附件邮件：
@Autowired private JavaMailSender sender; @Test public void sendMail2() throws MessagingException { MimeMessage message = sender.createMimeMessage(); MimeMessageHelper mailMessage = new MimeMessageHelper(message,true); mailMessage.setSubject("测试邮件主题"); mailMessage.setText("<a href=‘http://www.baidu.com‘>点击跳转百度</a>",true); mailMessage.setFrom("1590@163.com"); mailMessage.setTo("471@qq.com"); String path = "E:\\temp\\temp.jpg"; FileSystemResource fileSystemResource = new FileSystemResource(path); String fileName = path.substring(path.lastIndexOf(File.separator)+1); mailMessage.addAttachment(fileName,fileSystemResource); sender.send(message); }
5）使用模板引擎动态生成html页面发送：
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>你好<span th:text="${username}"></span></h1> <p>这是一个邮件测试模板</p> </body> </html>
@Autowired private JavaMailSender sender; @Autowired private TemplateEngine templateEngine; @Test public void sendMail3() throws MessagingException { MimeMessage message = sender.createMimeMessage(); MimeMessageHelper mailMessage = new MimeMessageHelper(message,true); mailMessage.setSubject("测试邮件主题"); mailMessage.setFrom("159@163.com"); mailMessage.setTo("471@qq.com"); //读取模板内容 Context context = new Context(); context.setVariable("username","张三"); String info = templateEngine.process("temp", context); mailMessage.setText(info,true); sender.send(message); }
