前面已经讲了使用springboot采用常规的javaweb方式发送邮件和使用spring模板发送邮件。但是发送的都是文本文件，现在来说一下使用spring模板发送一些其他的邮件。
1.pom.xml依赖
<!--spring发送邮件-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
<!--模板邮件-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
</dependency>
2.配置文件：
#####163邮箱######## spring.mail.host=smtp.163.com spring.mail.username=xxxxxxx@163.com #163邮箱授权码 spring.mail.password=********* spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.starttls.enable=true spring.mail.properties.mail.smtp.starttls.required=true
3.发送各种邮件方法：
@Controller public class ModelController { @Autowired private JavaMailSender mailSender; @Value("${spring.mail.username}") private String Sender; //读取配置文件中的参数 @Autowired private FreeMarkerConfigurer freeMarkerConfigurer; /** * spring发送文本邮件 */ @RequestMapping("/mail") @ResponseBody public String sendMail(){ SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(Sender); message.setTo("*********@qq.com"); message.setSubject("主题：简单邮件"); message.setText("测试邮件内容"); mailSender.send(message); return "发送成功！"; } /** * spring发送Html邮件 */ @RequestMapping("/mailHtml") @ResponseBody public String sendHtmlMail(){ MimeMessage message = null; try { message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(Sender); helper.setTo("*********@qq.com"); helper.setSubject("标题：发送Html内容"); StringBuffer sb = new StringBuffer(); sb.append("<h1>大标题-h1</h1>") .append("<p style='color:#F00'>红色字</p>") .append("<p style='text-align:right'>右对齐</p>"); helper.setText(sb.toString(), true); } catch (Exception e) { e.printStackTrace(); } mailSender.send(message); return "发送成功！"; } /** * spring发送带附件的邮件 */ @RequestMapping("/mailAttach") @ResponseBody public String sendAttachmentsMail(){ MimeMessage message = null; try { message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(Sender); helper.setTo("*********@qq.com"); helper.setSubject("主题：带附件的邮件"); helper.setText("带附件的邮件内容"); //注意项目路径问题，自动补用项目路径 FileSystemResource file = new FileSystemResource(new File("F:\临时\SpringBoot\src\main\resources\static\image\迪丽热巴.jpg")); //加入邮件 helper.addAttachment("热巴.jpg", file); } catch (Exception e){ e.printStackTrace(); } mailSender.send(message); return "发送成功！"; } /** * spring发送带静态资源的邮件,资源直接发在邮件内容里，不是附件形式。 */ @RequestMapping("/mailLine") @ResponseBody public String sendInlineMail(){ MimeMessage message = null; try { message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(Sender); helper.setTo("*********@qq.com"); helper.setSubject("主题：带静态资源的邮件"); //第二个参数指定发送的是HTML格式,同时cid:是固定的写法 helper.setText("<html><body>带静态资源的邮件内容 图片:<img src='cid:picture' /></body></html>", true); FileSystemResource file = new FileSystemResource(new File("F:\临时\SpringBoot\src\main\resources\static\image\迪丽热巴.jpg")); helper.addInline("picture",file); } catch (Exception e){ e.printStackTrace(); } mailSender.send(message); return "发送成功！"; } /** * spring发送模板邮件 */ @RequestMapping("/mailTemplate") @ResponseBody public String sendTemplateMail(){ MimeMessage message = null; try { message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(Sender); helper.setTo("*********@qq.com"); helper.setSubject("主题：模板邮件"); Map<String, Object> model = new HashedMap(); model.put("username", "zggdczfr"); //修改 application.properties 文件中的读取路径 // FreeMarkerConfigurer configurer = new FreeMarkerConfigurer(); // configurer.setTemplateLoaderPath("classpath:templates"); //读取 html 模板 Template template = freeMarkerConfigurer.getConfiguration().getTemplate("mail.html"); String html = FreeMarkerTemplateUtils.processTemplateIntoString(template, model); helper.setText(html, true); } catch (Exception e) { e.printStackTrace(); } mailSender.send(message); return "发送成功！"; } }
