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

一、SpringBoot整合

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

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

構建項目，加載相關jar包

2、在application.yml中配置郵件發送的相關信息

spring: mail: host: smtp.mxhichina.com #阿里云發送服務器地址 port: 25 #端口號 username: [email protected] #發送人地址 password: ENC(Grg2n2TYzgJv9zpwufsf37ndTe+M1cYk) #密碼

3、編寫郵件發送工具類MailUtil

MailUtil.java

/** * @author chenzan * @version V1.0 * @description 郵件發送 */@Componentpublic class MailUtil { @Autowired JavaMailSendermailSender; @Autowired MailPropertiesmailProperties; /** * 發送郵件測試方法 */ 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); } /** * 發送郵件-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 */@Datapublic class MailBean {private Stringsubject; private String content; private String toAccount; private File attachmentFile; private String attachmentFileName;}

4.發送

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、查看阿里云郵箱設置

支持SMTP/POP3/IMAP功能，輕松通過客戶端軟件（outlook、foxmail等）收發郵件。 詳細設置 點此查看

三、SpringBoot中集成了jasypt在一定程度上保證密碼的安全

1、添加依賴

<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中配置加密密鑰

jasypt: encryptor: password: XXXXXXX

3、生成密碼對應的密文

@RunWith(SpringRunner.class)@SpringBootTestpublic 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()中添加對應密文

password: ENC(Grg2n2TYzgJv9zpwufsf37ndTe+M1cYk) #密碼
