grails - 如何从Grails中的域/服务发送邮件

Question

我安装了this plugin，我想从Service / Domain类方法发送邮件，我这样做是

   class TrainingService {
      def mailService
      public def sendMail() {
        mailService.sendMail {
            multipart true
            to "abc@xyz.com"
            subject "Hello,"
            body 'How are you?'

          }
}

我收到错误“无法在空对象上调用方法sendMail()”，如何解决此问题

Answer 1

我缺少“发件人”属性，如果您使用的是多部分电子邮件，则还应该填写电子邮件的其他部分(代码片段):

mailService.sendMail {
            multipart true
            from '"Some account" <someaccount@email.com>'
            to 'anotheremail@somedomain.com'
            bcc emailAddresses.toArray()
            subject dto.title
            body emailPart1
            html g.render(
                    template: 'emailNotification',
                    model: [ name: dto.name ]
            )

}
