JavaMail Spring启动属性无法识别属性

Question

我有一个带有javamail的spring启动应用程序，我配置了spring。属性，但似乎不需要属性来发送电子邮件。

#mail properties
spring.mail.host = smtp.gmail.com
spring.mail.port = 587
spring.mail.username = [e-mail] 
spring.mail.password = eeee
spring.mail.protocol = smtp
spring.mail.defaultEncoding=UTF-8
spring.mail.smtp.starttls.enable=false
spring.mail.smtp.starttls.required=false
spring.mail.smtp.auth=true
spring.mail.smtp.connectiontimeout=5000
spring.mail.smtp.timeout=5000
spring.mail.smtp.writetimeout=5000 

下面是发送电子邮件的java代码

@Service
public class MailSenderServiceImpl implements IMailSenderService{

@Autowired
JavaMailSender mailSender;


@Override
public void sendEmailStatusNotification(Shipment shipment) throws IOException, MessagingException{
    final MimeMessage mimeMessage = this.mailSender.createMimeMessage();
    final MimeMessageHelper message = new MimeMessageHelper(mimeMessage, "UTF-8");
    message.setFrom(shipment.getSender().getSenderEmail());
    message.setTo(new String[] {shipment.getRecipient().getRecipientEmail()});
    message.setSubject("Shipment "+shipment.getTrackingNumber()+"status update");
    message.setText("the shipment status is now :"+shipment.getStatus().getLabel());
    this.mailSender.send(mimeMessage);
}

pom.xml

        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>

这里我们看到了这个错误

组织。springframework。邮政MailSendException:邮件服务器连接失败；嵌套的异常是com。太阳邮政util。MailConnectException:无法连接到主机，端口：localhost，25；超时-1；嵌套的例外是：java。网ConnectException:连接被拒绝：连接。失败消息：com。太阳邮政util。MailConnectException:无法连接到主机，端口：localhost，25；超时-1；嵌套的例外是：java。网ConnectException:连接被拒绝：连接；消息异常（1）为：失败消息1:com。太阳邮政util。MailConnectException:无法连接到主机，端口：localhost，25；超时-1；嵌套的例外是：java。网ConnectException:连接被拒绝：连接

任何想法？

默认情况下spring。属性不是属性源，请尝试将它们放入应用程序中。属性。
