為什么JavaMailSender-starttls不起作用-有解無憂

我正在嘗試在簡單的 Spring Boot 應用程式中配置郵件服務以發送電子郵件通知。

這是我的配置：

spring:
  main:
    web-application-type: none

  mail:
    host: ${FOOD_MAIL_HOST:smtp.gmail.com}
    port: ${FOOD_MAIL_PORT:587}
    username: ${FOOD_MAIL_USERNAME:my.name@gmail.com}
    password: ${FOOD_MAIL_PASSWORD:mypassword}
    properties:
      smtp:
        auth: true
        starttls:
          enable: true
  freemarker:
    charset: UTF-8
    template-loader-path: classpath:/templates

這是我的 pom.xml：

hete 是我的代碼：

import freemarker.template.Template;
import freemarker.template.TemplateException;
import lombok.RequiredArgsConstructor;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.messaging.MessagingException;
import org.springframework.stereotype.Service;
import org.springframework.ui.freemarker.FreeMarkerTemplateUtils;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;

import javax.mail.internet.MimeMessage;
import java.io.IOException;
import java.util.Map;

@Service
@RequiredArgsConstructor
public class EmailService {

    private final FreeMarkerConfigurer freemarkerConfigurer;

    private final JavaMailSender emailSender;

    public void sendMessageUsingFreemarkerTemplate(
            String to, String subject, Map<String, Object> templateModel)
            throws IOException, TemplateException, MessagingException, javax.mail.MessagingException {

        Template freemarkerTemplate = freemarkerConfigurer.getConfiguration()
                .getTemplate("template-freemarker.ftl");
        String htmlBody = FreeMarkerTemplateUtils.processTemplateIntoString(freemarkerTemplate, templateModel);

        sendHtmlMessage(to, subject, htmlBody);
    }

    private void sendHtmlMessage(String to, String subject, String htmlBody) throws MessagingException, javax.mail.MessagingException {
        MimeMessage message = emailSender.createMimeMessage();
//        message
        MimeMessageHelper helper = new MimeMessageHelper(message, true, "UTF-8");
        helper.setTo(to);
        helper.setSubject(subject);
        helper.setText(htmlBody, true);
        emailSender.send(message);
    }
}

這是我的測驗：

//            message.setRecipients(

//
//        } catch (MessagingException e) {

//        }

        final Map<String, Object> templateModel = new HashMap<>();
        templateModel.put("recipientName", "Mr. Recipient");
        templateModel.put("text", ORDER_CREATED);
        templateModel.put("senderName", "Vanusha");
        emailService.sendMessageUsingFreemarkerTemplate("[email protected]", "test", templateModel);
    }
}

具有類似設定的注釋代碼可以很好地發送郵件。但是當我嘗試使用 JavaMailSender 時，我收到例外：

我無法弄清楚所有教程都解釋的問題，以下部分是關鍵：

     smtp:
        auth: true
        starttls:
          enable: true

但是我的服務不起作用。請幫忙。

uj5u.com熱心網友回復：

我猜你的配置不正確。代替

  mail:
    properties:
      smtp:
        auth: true
        starttls:
          enable: true

你應該試試：

  mail:
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true

將它與我們通常定義的屬性相關聯，如下所示：

spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
