**application.properties：** 这里使用jasypt加密，可参考文章：[SpringBoot整合Jasypt实现对配置文件加密][SpringBoot_Jasypt]

jasypt.encryptor.password=944ec5b7-148f-4db6-ae0e-612a5106507b
    #邮箱服务器地址
    spring.mail.host=smtp.163.com
    #用户名
    spring.mail.username=wanyingjing@163.com
    #密码
    spring.mail.password= 
    #编码
    spring.mail.default-encoding=UTF-8

**MailApplication：**

@SpringBootApplication
    public class MailApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(MailApplication.class, args);
        }
    }

## 1、发送简单邮件 ##

**MailApplicationTests：**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailApplicationTests { 
    
        @Autowired
        private MailService mailService; 
    
        @Test
        public void simpleMail() throws Exception { 
            String to = "wanyingjing@163.com";
            String subject = "简单邮件";
            String content = "测试发送简单邮件";
            mailService.sendSimpleMail(to, subject, content);
        }
    }

**MailService：**

public interface MailService { 
    
        /** * 发送简单邮件 * * @param to * @param subject * @param content */
        public void sendSimpleMail(String to, String subject, String content);
    }

**MailServiceImpl：**

@Service
    public class MailServiceImpl implements MailService { 
    
        private final Logger logger = LoggerFactory.getLogger(MailServiceImpl.class);
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${spring.mail.username}")
        private String from;
    
        @Override
        public void sendSimpleMail(String to, String subject, String content) { 
            SimpleMailMessage message = new SimpleMailMessage();
            message.setFrom(from);//发件人
            message.setTo(to);//目标
            message.setSubject(subject);//主题
            message.setText(content);//内容
            try { 
                mailSender.send(message);
                logger.info("一份简单邮件已发送。");
            } catch (Exception e) { 
                logger.error("发送简单邮件时发生异常！", e);
            }
        }
    }

## 2、发送html邮件 ##

**MailApplicationTests：**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailApplicationTests { 
    
        @Autowired
        private MailService mailService; 
    
        @Test
    	public void htmlMail() throws Exception { 
    	    String to = "wanyingjing@163.com";
    	    String subject = "html邮件";
    	    String content = "<html>\n" + "<body>\n" + " <h1>hello world ! 这是一封html邮件!</h1>\n" + "</body>\n" + "</html>";
    	    mailService.sendHtmlMail(to, subject, content);
    	}
    }

**MailService：**

public interface MailService { 
    
    	/** * 发送HTML邮件 * * @param to * @param subject * @param content */
    	public void sendHtmlMail(String to, String subject, String content);
    }

**MailServiceImpl：**

@Service
    public class MailServiceImpl implements MailService { 
    
        private final Logger logger = LoggerFactory.getLogger(MailServiceImpl.class);
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${spring.mail.username}")
        private String from;
    
        @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(from);
    	        helper.setTo(to);
    	        helper.setSubject(subject);
    	        helper.setText(content, true);
    	        mailSender.send(message);
    	        logger.info("一份html邮件已成功");
    	    } catch (MessagingException e) { 
    	        logger.error("发送html邮件时发生异常！", e);
    	    }
    	}
    }

## 3、发送携带附件的邮件 ##

**MailApplicationTests：**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailApplicationTests { 
    
        @Autowired
        private MailService mailService; 
    
        @Test
    	public void attachmentsMail() throws Exception { 
    	    String to = "wanyingjing@163.com";
    	    String subject = "带附件的邮件";
    	    String content = "您有附件，请注意查收！";
    	    String filePath = "C:\\Users\\EDZ\\Desktop\\application.log";//附件
    	    mailService.sendAttachmentsMail(to, subject, content, filePath);
    	}
    }

**MailService：**

public interface MailService { 
    
        /** * 发送带有附件的邮件 * * @param to * @param subject * @param content * @param filePath */
    	public void sendAttachmentsMail(String to, String subject, String content, String filePath);
    }

**MailServiceImpl：**

@Service
    public class MailServiceImpl implements MailService { 
    
        private final Logger logger = LoggerFactory.getLogger(MailServiceImpl.class);
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${spring.mail.username}")
        private String from;
    
        @Override
    	public void sendAttachmentsMail(String to, String subject, String content, String filePath) { 
    	    MimeMessage message = mailSender.createMimeMessage();
    	    try { 
    	        MimeMessageHelper helper = new MimeMessageHelper(message, true);
    	        helper.setFrom(from);
    	        helper.setTo(to);
    	        helper.setSubject(subject);
    	        helper.setText(content, true);
    	        FileSystemResource file = new FileSystemResource(new File(filePath));
    	        String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
    	        helper.addAttachment(fileName, file);
    	        mailSender.send(message);
    	        logger.info("一份带附件的邮件已发送。");
    	    } catch (MessagingException e) { 
    	        logger.error("发送带附件的邮件时发生异常！", e);
    	    }
    	}
    }

## 4、发送携带静态资源的邮件 ##

**MailApplicationTests：**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailApplicationTests { 
    
        @Autowired
        private MailService mailService; 
    
        @Test
    	public void staticResourceMail() throws Exception { 
    	    String to = "wanyingjing@163.com";
    	    String subject = "带图片的邮件";
    	    String rscId = "neo006";
    	    String content = "<html><body>详情请看：<img src=\'cid:" + rscId + "\' ></body></html>";
    	    String imgPath = "C:\\Users\\EDZ\\Desktop\\微信截图_20190531102741.png";
    	    mailService.sendInlineResourceMail(to, subject, content, imgPath, rscId);
    	}
    }

**MailService：**

public interface MailService { 
    
        /** * 发送带静态资源的邮件 * * @param to * @param subject * @param content * @param rscPath * @param rscId */
    	public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId);
    }

**MailServiceImpl：**

@Service
    public class MailServiceImpl implements MailService { 
    
        private final Logger logger = LoggerFactory.getLogger(MailServiceImpl.class);
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${spring.mail.username}")
        private String from;
    
        @Override
    	public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) { 
    	    MimeMessage message = mailSender.createMimeMessage();
    	    try { 
    	        MimeMessageHelper helper = new MimeMessageHelper(message, true);
    	        helper.setFrom(from);
    	        helper.setTo(to);
    	        helper.setSubject(subject);
    	        helper.setText(content, true);
    	        FileSystemResource res = new FileSystemResource(new File(rscPath));
    	        helper.addInline(rscId, res);
    	        mailSender.send(message);
    	        logger.info("一份带静态资源的邮件已发送。");
    	    } catch (MessagingException e) { 
    	        logger.error("发送带静态资源的邮件时发生异常！", e);
    	    }
    	}
    }

## 5、发送html页面模板的邮件 ##

**MailApplicationTests：**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailApplicationTests { 
    
        @Autowired
        private MailService mailService; 
    
        @Autowired
        private TemplateEngine templateEngine;
    
        @Test
    	public void templateMail() { 
    	    Context context = new Context();
    	    String emailContent = templateEngine.process("emailTemplate", context);
    	    System.out.println(emailContent);
    	    String to = "wanyingjing@163.com";
    	    String sbuject = "模板邮件";
    	    mailService.sendHtmlMail(to, sbuject, emailContent);
    	}
    }

**MailService：**

public interface MailService { 
    
        /** * 发送HTML邮件 * * @param to * @param subject * @param content */
    	public void sendHtmlMail(String to, String subject, String content);
    }

**MailServiceImpl：**

@Service
    public class MailServiceImpl implements MailService { 
    
        private final Logger logger = LoggerFactory.getLogger(MailServiceImpl.class);
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${spring.mail.username}")
        private String from;
    
        @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(from);
    	        helper.setTo(to);
    	        helper.setSubject(subject);
