SpringBoot整合JavaMail通过阿里云企业邮箱发送邮件的实现

SpringBoot整合JavaMail通过阿里云企业邮箱发送邮件的实现

javaMail是Java开发中邮件处理的开源类库，支持常用协议如：SMTP、POP3、IMAP

一、SpringBoot整合

1、需要在pom文件中添加依赖spring-boot-starter-mail

org.springframework.boot

spring-boot-starter-mail

构建项目，加载相关jar包

2、在application.yml中配置邮件发送的相关信息

spring:

mail:

host: smtp.mxhichina.com #阿里云发送服务器地址

port: 25 #端口号

username: XXX@XXXX.com #发送人地址

password: ENC(Grg2n2TYzgJv9zpwufsf37ndTe+M1cYk) #密码

3、编写邮件发送工具类MailUtil

MailUtil.java

/**

* @author chenzan

* @version V1.0

* @description 邮件发送

*/

@Component

public class MailUtil {

@Autowired

JavaMailSendermailSender;

@Autowired

MailPropertiesmailProperties;

/**

* 发送邮件测试方法

*/

public void sendMail(MailBean mailBean) {

SimpleMailMessage mimeMessage =new SimpleMailMessage();

mimeMessage.setFrom(mailProperties.getUsername());

mimeMessage.setTo(mailBean.getToAccount());

mimeMessage.setSubject(mailBean.getSubject());

mimeMessage.setText(mailBean.getContent());

mailSender.send(mimeMessage);

}

/**

* 发送邮件-附件邮件

* @param boMailBean

*/

public boolean sendMailAttachment(MailBean mailBean) {

try {

MimeMessage mimeMessage =mailSender.createMimeMessage();

MimeMessageHelper helper =new MimeMessageHelper(mimeMessage, true);

helper.setFrom(mailProperties.getUsername());

helper.setTo(boMailBean.getToAccount());

helper.setSubject(mailBean.getSubject());

helper.setText(mailBean.getContent(), true);

// 增加附件名称和附件

helper.addAttachment(MimeUtility.encodeWord(boMailBean.getAttachmentFileName(), "utf-8", "B"), mailBean.getAttachmentFile());

mailSender.send(mimeMessage);

return true;

}catch (MessagingException e) {

e.printStackTrace();

return false;

}

}

MailBean.java

/**

* @author chenzan

* @version V1.0

*/

@Data

public class MailBean {

private Stringsubject;

private String content;

private String toAccount;

private File attachmentFile;

private String attachmentFileName;

}

4.发送

String email = "XXX@email.com";

String content="测试内容";

String subject = "测试主题";

MailBean mailBean =new MailBean ();

mailBean .setToAccount(email);

boMailBean.setSubject(subject );

boMailBean.setContent(content);

boolean resultSenhttp://d =mailUtil.sendMailAttachment(boMailBean);

二、查看阿里云邮箱设置

支持SMTP/POP3/IMAP功能，轻松通过客户端软件（outlook、foxmail等）收发邮件。 详细设置 点此查看

三、SpringBoot中集成了jasypt在一定程度上保证密码的安全

1、添加依赖

1.9

com.github.ulisesbocchio

jasypt-spring-boot-starter

${jasypt.version}

2、在application.yml中配置加密密钥

jasypt:

encryptor:

password: XXXXXXX

3、生成密码对应的密文

@RunWith(SpringRunner.class)

@SpringBootTest

public class EncryptTests {

@Autowired

StringEncryptor stringEncryptor;

@Test

public void encryptPwd() {

String result = stringEncryptor.encrypt("XXXX");

System.out.println(result);

}

}

4、密文替换

在ENC()中添加对应密文

password: ENC(Grg2n2TYzgJv9zpwufsf37ndTe+M1cYk) #密码
