使用 Spring boot 對接 SMTP gateway 發 email ，相對是容易的。 基本上，它就是會使用自建的 org.springframework.mail.javamail. , 對接 javax.mail. jakarta.mail. 以前的所有設定值 ，都可以經 spring.mail.properties. 傳入 例如 spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.ssl.enable=true spring.mail.properties.mail.smtp.socketFactory.port=465 就等於過去 java.util.Properties props = new java.util.Properties; props.putquot;mail.smtp.authquot;, quot;truequot;; props.putquot;mail.smtp.ssl.enablequot;, quot;truequot;; props.putquot;mail.smtp.socketFactory.portquot;, quot;465quot;; 一個最簡單可以連去 google smtp 的簡易 code 如下 ### application.properties spring.mail.host=smtp.gmail.com spring.mail.port=587 spring.mail.username= spring.mail.password= spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.starttls.enable=true SpringBootEmailApplicationTests.java @SpringBootTest class SpringBootEmailApplicationTests @Autowired private JavaMailSender javaMailSender; @Valuequot;$spring.mail.usernamequot; private String fromAddress; private static final Logger LOG = LoggerFactory.getLoggerSpringBootEmailApplicationTests.class; @Test void contextLoads try SimpleMailMessage mailMessage = new SimpleMailMessage; mailMessage.setFromfromAddress; mailMessage.setToquot;XXXXXXXXquot;; mailMessage.setTextquot;this is backend email trigger for spring bootquot;; mailMessage.setSubjectquot;spring boot test mailquot;; javaMailSender.sendmailMessage; catch Exception e LOG.errorquot;Error while Sending Mailquot;; throw new RuntimeExceptione; github 原始碼 httpsgithub.commacauyeahspringbootdemotreemainspringboottutorialspringbootemail
