Question

我越来越了解JHipster和Spring但我在注册新用户时遇到了问题。当我尝试注册新用户时，我收到以下错误消息。根据此Stackoverflow问题Email service in Jhipster，我必须填写application-dev.yml或application-prod.yml中的属性。

网络应用程序应该来自不同的人，他们应该能够自我注册。我不认为这是正确的方法吗？我在这里错过了什么吗？我需要SMTP服务器吗？

我的application-dev.yaml中有以下条目：

 mail:
        host: localhost
        port: 25
        username:
        password:
    messages:
        cache-seconds: 1
    thymeleaf:
        cache: false
    http:
        multipart:

            max-request-size: 20MB

是的，您需要一个SMTP服务器。查看我们在www.jhipster.tech上的提示部分，您会找到how to configure email和how to use MailDev with Docker
