Question

我正在尝试从Service类发送邮件。

从UserCOntroller.groovy我正在调用发送电子邮件的服务方法

maillingService.sendEmails(user)

MailingService.groovy 服务 ：以下代码

class MailingService {
    def sendEmails(User user) {
        // def mailService // I ALSO TRIED WITH AND WITHOUT THIS ATTRIBUTE
        mailService.sendMail {
            to "fred@g2one.com","ginger@g2one.com"
            from "john@g2one.com"
            cc "marge@g2one.com", "ed@g2one.com"
            bcc "joe@g2one.com"
            subject "Hello John"
            body 'this is some text'
         }
}

我得到的错误是：

No such property: mailService for class: mypro.MailingService. Stacktrace follows:
Message: No such property: mailService for class: mypro.MailingService

编辑代码

def sendEmail(def u){

    MailingService m = new MailingService()
m.sendEmails(u)

}

你使用def mailService走在正确的轨道上，但它需要是一个字段声明（在类级别），而不是方法内的局部变量：

class MailingService {
    def mailService

    def sendEmails(User user) {
        mailService.sendMail {
            to "fred@g2one.com","ginger@g2one.com"
            from "john@g2one.com"
            cc "marge@g2one.com", "ed@g2one.com"
            bcc "joe@g2one.com"
            subject "Hello John"
            body 'this is some text'
        }
    }
}

此外，您应该不在控制器中自己实例化服务类，而应该像对上面的mailService一样自动装配它：

class SampleController {
    def mailingService

    def sendEmail(User u) {
        mailingService.sendEmails(u)
    }
}
