org.springframework.mail.MailSendException: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 553 authentication is required,163 smtp12,EMCowAAXfwfWaTpdysD_Cg--.58754S2 1564109270

原代码-发送失败(这种方式在spring-context-support-4.3.6.RELEASE下没问题，在spring-context-support-5.0.4.RELEASE下有问题)

props.put("mail.smtp.auth", true);

修改后代码-发送成功

props.put("mail.smtp.auth", "true");

 

完整代码：

JavaMailSenderImpl tempMailSender = new JavaMailSenderImpl();
tempMailSender.setHost("smtp.163.com");
tempMailSender.setPort(25);
tempMailSender.setProtocol("smtp");
tempMailSender.setUsername("[email protected]");
tempMailSender.setPassword("xxxxx");
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.connectiontimeout", 10000);
props.put("mail.smtp.timeout",10000);
tempMailSender.setJavaMailProperties(props);
        
MimeMessage mimeMessage = tempMailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "utf-8");

helper.setFrom("[email protected]");
helper.setTo("[email protected]");
helper.setSubject("2222");
helper.setText("=-=-=-=--", true);
