email - grails邮件不工作

Question

chalice 项目。我使用电子邮件插件并在尝试调用方法“sendMail”时出现异常

错误:

Caused by: org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp. Failed messages: javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp; message exceptions (1) are:
Failed message 1: javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp

配置.groovy

grails {
    mail {
        host = "smtp.gmail.com"
        port = 465
        username = "mymail@gmail.com"
        password = "mypass"
        props = ["mail.smtp.auth":"true",
                //"mail.smtp.port":"465",
                //"mail.debug":"true",
                "mail.smtp.socketFactory.port":"465",
                "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
                "mail.smtp.socketFactory.fallback":"false"]
    }
}

发送示例

sendMail {
                    to "fred@gmail.com"
                    subject "Hello Fred"
                    body 'How are you?'
                }

我究竟做错了什么？

错误说 Unable to locate provider for protocol: smtp .似乎您缺少 smtp 协议(protocol)的一些依赖项，这看起来很奇怪，显然您缺少 javamail (?)。因为代码对我来说似乎很好。
