JavaMail是Java開發中郵件處理的開源類庫，支援常用協議如：SMTP、POP3、IMAP

一、SpringBoot整合

1、需要在pom檔案中新增依賴spring-boot-starter-mail

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

構建專案，載入相關jar包

2、在application.yml中配置郵件傳送的相關資訊

spring:
  mail:
   host: smtp.mxhichina.com   #阿里雲傳送伺服器地址
   port: 25           #埠號
   username: [email protected]    #傳送人地址 
   password: ENC(Grg2n2TYzgJv9zpwufsf37ndTe+M1cYk)  #密碼

3、編寫郵件傳送工具類MailUtil

MailUtil.java

/**
 * @author chenzan
 * @version V1.0
 * @description 郵件傳送
 */

@Component
public class MailUtil {
  @Autowired
  JavaMailSendermailSender;
  @Autowired
  MailPropertiesmailProperties;
  /**
  * 傳送郵件測試方法
  */
  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);
  }

  /**
  * 傳送郵件-附件郵件
  * @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);
      // 增加附件名稱和附件
      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.傳送

String email = "[email protected]";
String content="測試內容";
String subject = "測試主題";
MailBean mailBean =new MailBean ();
mailBean .setToAccount(email);
boMailBean.setSubject(subject );
boMailBean.setContent(content);
boolean resultSend =mailUtil.sendMailAttachment(boMailBean);

二、檢視阿里雲郵箱設定

支援SMTP/POP3/IMAP功能，輕鬆通過客戶端軟體（outlook、foxmail等）收發郵件。 詳細設定 點此檢視

三、SpringBoot中集成了jasypt在一定程度上保證密碼的安全

1、新增依賴

<properties>
  <jasypt.version>1.9</jasypt.version>
</properties>
<dependency>
  <groupId>com.github.ulisesbocchio</groupId>
  <artifactId>jasypt-spring-boot-starter</artifactId>
  <version>${jasypt.version}</version>
</dependency>

2、在application.yml中配置加密金鑰

jasypt:
 encryptor:
 password: XXXXXXX

3、生成密碼對應的密文

@RunWith(SpringRunner.class)
@SpringBootTest
public class EncryptTests {
 @Autowired
  StringEncryptor stringEncryptor;

  @Test
  public void encryptPwd() {
    String result = stringEncryptor.encrypt("XXXX");
    System.out.println(result);
  }
}

4、密文替換

在ENC()中新增對應密文

password: ENC(Grg2n2TYzgJv9zpwufsf37ndTe+M1cYk)  #密碼
