import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

@Component
public class MailClient {

	private static final Logger logger = LoggerFactory.getLogger(MailClient.class);

	@Autowired
	private JavaMailSender mailSender;

	@Value("${spring.mail.username}")
	private String from;

	/***
	 * 
	 * @param to 发送邮件给谁？
	 * @param subject
	 * @param content
	 */
	public void sendMail(String to, String subject, String content) {
		try {
			MimeMessage message = mailSender.createMimeMessage();
			MimeMessageHelper helper = new MimeMessageHelper(message);
			helper.setFrom(from);
			helper.setTo(to);
			helper.setSubject(subject);
			helper.setText(content, true);
			mailSender.send(helper.getMimeMessage());
		} catch (MessagingException e) {
			logger.error("发送邮件失败:" + e.getMessage());
		}
	}

}

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = CommunityApplication.class)
public class MailTests {

    @Autowired
    private MailClient mailClient;

    @Autowired
    private TemplateEngine templateEngine;

    @Test
    public void testTextMail() {
        mailClient.sendMail("lpzh1218@126.com", "TEST", "Welcome.");
