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
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency>
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: #阿里云发送服务器地址port: 25 #端口号username: XXX@ #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*/@Componentpublic class MailUtil {@AutowiredJavaMailSendermailSender;@AutowiredMailPropertiesmailProperties;/*** 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*/@Datapublic class MailBean {private Stringsubject;private String content;private String toAccount;private File attachmentFile;private String attachmentFileName;}
4.发送
String email = "XXX@";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 resultSend =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
<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中配置加密密钥
jasypt:encryptor:password: XXXXXXX
3、生成密码对应的密文
@RunWith(SpringRunner.class)@SpringBootTestpublic class EncryptTests {@AutowiredStringEncryptor stringEncryptor;@Testpublic 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
