SpringBoot 整合mail邮件

1.1、添加mail的起步依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

1.2、获取QQ邮箱授权码

1、QQ邮箱->设置->账户->POP3/SMTP服务:开启服务后会获得QQ的授权码.


2、设置->POP3/SMTP服务->勾选，之后保存，会弹出设置密码，这个密码和邮箱密码不一样哦

1.3、Mail配置文件（springboot.yml）

1.3.1 qq邮箱配置

# JavaMailSender 邮件发送的配置
spring.mail.host=smtp.qq.com
spring.mail.username=用户qq邮箱
#QQ邮箱的授权码
spring.mail.password=qq邮箱授权码
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.default-encoding=UTF-8

1.3.2、 163邮箱配置

spring.mail.host=smtp.163.com
spring.mail.username=用户163邮箱
spring.mail.password=邮箱密码
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.default-encoding=UTF-8

1.4、实现过程

1.4.1、 163配置文件

spring:
  #邮箱配置
  mail:
    host: smtp.qq.com
    username: *******@qq.com
    #QQ邮箱的授权码
    password: 自己申请
    default-encoding: UTF-8
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true
#设置一个邮件发送人
lance:
  mail:
    sender: ********@qq.com

1.4.2 、实体bean

/**
 * @author mhb(mhb)
 * @function  发送邮件-封装接受者信息
 */
@Data
public class MailBean implements Serializable {
    private String recipient;   //邮件接收人
    private String subject; //邮件主题
    private String content; //邮件内容

}

1.4.3 、 发送简单格式的邮件

@RunWith(SpringRunner.class)
@SpringBootTest(classes =QuartzSpringBootApplication.class )
	public class client {
    @Value("${spring.mail.username}")
    private String MAIL_SENDER;
    @Autowired
    private JavaMailSender javaMailSender;
    private static final Logger LOG = LoggerFactory.getLogger(Logger.class);
	
	//发送简单的邮件
	@Test
	public void contextLoads() {

		MailBean mailBean = new MailBean();
		mailBean.setContent("测试");
		mailBean.setRecipient("************@163.com");
		mailBean.setSubject("测试邮件");

		try {
			SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
			//邮件发送人
			simpleMailMessage.setFrom(MAIL_SENDER);
			//邮件接收人
			simpleMailMessage.setTo(mailBean.getRecipient());
			//邮件主题
			simpleMailMessage.setSubject(mailBean.getSubject());
			//邮件内容
			simpleMailMessage.setText(mailBean.getContent());
			javaMailSender.send(simpleMailMessage);
		} catch (Exception e) {
			LOG.error("邮件发送失败", e.getMessage());
		}

	}
}

1.4.4 、 发送html格式的邮件

//发送html格式的邮件
	@Test
	public void sendHTMLMail() {
		MailBean mailBean = new MailBean();
		mailBean.setContent("测试html格式的邮件");
		mailBean.setRecipient("************@163.com");
		mailBean.setSubject("测试html格式的邮件");
		MimeMessage mimeMailMessage = null;
		try {
			mimeMailMessage = javaMailSender.createMimeMessage();
			MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
			mimeMessageHelper.setFrom(MAIL_SENDER);
			mimeMessageHelper.setTo(mailBean.getRecipient());
			mimeMessageHelper.setSubject(mailBean.getSubject());
			StringBuilder sb = new StringBuilder();
			sb.append("<h1>SpirngBoot测试邮件HTML</h1>")
					.append("\"<p style='color:#F00'>你是真的太棒了！</p>")
					.append("<p style='text-align:right'>右对齐</p>");
			mimeMessageHelper.setText(sb.toString(), true);
			javaMailSender.send(mimeMailMessage);
		} catch (Exception e) {
			LOG.error("邮件发送失败", e.getMessage());
		}
	}

1.4.5 、 发送html格式的邮件

 //发送带附件格式的邮件
	@Test
	public void sendAttachmentMail() {
		MailBean mailBean = new MailBean();
		mailBean.setContent("测试附件格式的邮件");
		mailBean.setRecipient("************@163.com");
		mailBean.setSubject("测试附件格式的邮件");
		MimeMessage mimeMailMessage = null;
		try {
			mimeMailMessage = javaMailSender.createMimeMessage();
			MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
			mimeMessageHelper.setFrom(MAIL_SENDER);
			mimeMessageHelper.setTo(mailBean.getRecipient());
			mimeMessageHelper.setSubject(mailBean.getSubject());
			mimeMessageHelper.setText(mailBean.getContent());
			//文件路径
			FileSystemResource file = new FileSystemResource(new File("src/main/resources/static/image/mail.jpg"));
			mimeMessageHelper.addAttachment("mail.jpg", file);

			javaMailSender.send(mimeMailMessage);
		} catch (Exception e) {
			LOG.error("邮件发送失败", e.getMessage());
		}
	}

1.4.6 、 发送基于thymeleaf为模板的邮件

1、pom中导入thymeleaf的包

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

2、在resorces/templates下创建emailTemplate.html

<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8"/>
    <title>Title</title>
</head>
<body>
您好,这是验证邮件,请点击下面的链接完成验证,<br/>
<a href="#" th:href="@{http://www.qinfeng.com/{id}(id=${id}) }">激活账号</a>
</body>
</html>

3、解析模板并发送

 @Test
    public void sendTemplateMail() {
        //创建邮件正文
        Context context = new Context();
        context.setVariable("id", "006");
        String emailContent = templateEngine.process("emailTemplate", context);

        MimeMessage mimeMailMessage = null;
        try {
            mimeMailMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
            mimeMessageHelper.setFrom(MAIL_SENDER);
            mimeMessageHelper.setTo("************@163.com");
            mimeMessageHelper.setSubject("测试thymyleaf");
           /* StringBuilder sb = new StringBuilder();
            sb.append(emailContent);*/

            mimeMessageHelper.setText(emailContent,true);
            javaMailSender.send(mimeMailMessage);
        } catch (Exception e) {
            LOG.error("邮件发送失败", e.getMessage());
        }
    }
