springboot实现邮件功能：使用thymeleaf模板发送邮件

### 1.建springboot项目，导入依赖；application.properties配置文件，看 ###

[springboot发送邮件（1）：发送简单邮件][springboot_1]

使用thymeleaf模板需要在application.properties添加：

# THYMELEAF (ThymeleafAutoConfiguration)
    spring.thymeleaf.check-template-location=true
    spring.thymeleaf.prefix=classpath:/templates/
    spring.thymeleaf.excluded-view-names= # comma-separated list of view names   that should be excluded from resolution
    spring.thymeleaf.view-names= # comma-separated list of view names that can be resolved
    spring.thymeleaf.suffix=.html
    spring.thymeleaf.mode=HTML5
    spring.thymeleaf.encoding=UTF-8
    spring.thymeleaf.content-type=text/html # ;charset=<encoding> is added

如果不加，会报错。

### 2.编写服务接口，实现类： ###

/**
     * 邮件服务接口
     * Created by ASUS on 2018/5/5
     *
     * @Authod Grey Wolf
     */
    public interface MailService {
    
    
        /**
         * 发送html格式的邮件
         * @param to
         * @param subject
         * @param content
         */
        void sendHtmlMail(String to,String subject,String content);
    
    
    }

/**
     *
     * 邮件服务类
     * Created by ASUS on 2018/5/5
     *
     * @Authod Grey Wolf
     */
    
    @Service("mailService")
    public class MailServiceImpl implements MailService {
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${mail.fromMail.addr}")
        private String form;
        
    
        /**
         * 发送html格式的邮件
         * @param to 接受者
         * @param subject 主题
         * @param content 内容
         */
        @Override
        public void sendHtmlMail(String to, String subject, String content) {
            MimeMessage message=mailSender.createMimeMessage();
            try {
                //true表示需要创建一个multipart message
                MimeMessageHelper helper=new MimeMessageHelper(message,true);
                helper.setFrom(form);
                helper.setTo(form);
                helper.setSubject(subject);
                helper.setText(content,true);
                mailSender.send(message);
                System.out.println("html格式邮件发送成功");
            }catch (Exception e){
                System.out.println("html格式邮件发送失败");
            }
        }
    
      
    
    
    }

### 3.编写测试类： ###

/**
     * 发送邮件测试类
     * Created by ASUS on 2018/5/5
     *
     * @Authod Grey Wolf
     */
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailTest {
    
        @Autowired
        private MailService mailService;
    
        @Autowired
        private TemplateEngine templateEngine;
    
        @Value("${mail.fromMail.addr}")
        private String form;
    
    
        @Test
        public void sendTemplateMail() throws  Exception{
            //创建邮件正文
             //是导这个包import org.thymeleaf.context.Context;
            Context context = new Context();
            context.setVariable("username","Grey Wolf");
            //获取thymeleaf的html模板
            String emailContent= templateEngine.process("template", context);
            mailService.sendHtmlMail(form,"这是thymeleaf模板邮件",emailContent);
        }
    
    }

### 4.测试效果： ###
