If You did not use SSL Certificate in You web application than try my code, it work perfectly in spring boot, text mail and HTML Mail both working perfectly.

<pre><code>@Autowired
private JavaMailSender mailSender;

@RequestMapping(value="/ShareVecancy",method=RequestMethod.GET)
public ModelAndView sendEmailToReference(HttpServletRequest request,HttpSession session){

 try {

 MimeMessage mail = mailSender.createMimeMessage();
 MimeMessageHelper messageHelper = new MimeMessageHelper(mail, true);
 messageHelper.setTo("reciverEmail@mail.com");
 messageHelper.setSubject("Testing mail");
 messageHelper.setText("HTML Text or Any text You want to send ", true);
 mailSender.send(mail);

 } catch (MailException e) {
 e.printStackTrace();
 }


}
</code></pre>

You could also try the below settings but i couldn't give more information regarding this as it will be a long post. However <a href="https://www.geeksforgeeks.org/sending-email-java-ssltls-authentication/" rel="nofollow noreferrer">GeeksForGeeks</a> do explain what everything does in the spring mail properties, also google has it's own guidelines which you can find <a href="https://support.google.com/a/answer/176600?hl=en#zippy=%2Cuse-the-gmail-smtp-server" rel="nofollow noreferrer">here</a>
p.s. I have also disabled the Access to less secure applications from the gmail account settings

Below is my email service class (not that professional but for a personal projects it does the trick I need)
<pre class="lang-java prettyprint-override"><code>@Service
@AllArgsConstructor
@Slf4j
public class EmailService implements EmailSender {

 private final JavaMailSender mailSender;

 @Override
 @Async
 public void send(String to, String email) {
 try {
 MimeMessage mimeMessage = mailSender.createMimeMessage();
 MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, &quot;utf-8&quot;);
 helper.setText(email, true);
 helper.setTo(to);
 helper.setSubject(&quot;Your subject&quot;);
 helper.setFrom(&quot;xxxxxx@gmail.ro&quot;);
 mailSender.send(mimeMessage);
 } catch (MessagingException e) {
 log.error(&quot;failed to send email&quot;, e);
 throw new IllegalStateException(&quot;failed to send email&quot;);
 }
 }
}
</code></pre>

I want to send emails using gmail smtp server and spring mail sender, it doesn' throw any exceptions but my mail isn't sent i don't receive it.

Here's how Service looks:

<pre><code>@Service
public class MailSenderService {

 @Autowired
 public MailSender mailSender;

 public void prepareAndSend(String recipient, String message) {
 try {

 SimpleMailMessage mail = new SimpleMailMessage();
 String from = "testSender1@gmail.com";
 String to = "testRecipient1@gmail.com";
 String subject = "Test subject";
 mail.setFrom(from);
 mail.setTo(recipient);
 mail.setSubject(subject);
 mail.setText(message);
 mailSender.send(mail);
 } catch (Exception ex) {
 ex.printStackTrace();
 }
 }
}
</code></pre>

AppProperties 

<pre><code>spring.mail.host = smtp.gmail.com
spring.mail.username = ********@gmail.com
spring.mail.password = ********
spring.mail.properties.mail.smtp.auth = true
spring.mail.properties.mail.smtp.socketFactory.port = 465
spring.mail.properties.mail.smtp.socketFactory.class = javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback = false
spring.mail.properties.mail.smtp.ssl.enable = true
</code></pre>

And pom dependency

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
 &lt;artifactId&gt;spring-boot-starter-mail&lt;/artifactId&gt;
&lt;/dependency&gt;
</code></pre>

I deploy my app on port 8080 and just call this service with these two parameters, no exception is caught but in my testRecipient1 inbox i don't find any new mail, what have i missed ?
