如何用Groovy在Grails中调用服务 [英] How to call Service in Grails with groovy

问题描述

我有一项服务，因为我有一种方法可以打电话，我该如何访问此服务。
我看到了短信插件，并安装它，我怎么能从我的应用程序发送短信到不同的手机。我跟着grails短信插件，但我没有得到任何结果ecxept ecxeptions

I have one service in that i have a method to call and how can i acces this service. I have seen sms plugin and installed it and How can i send sms from my application to the different mobiles.I followed the grails sms plugin but i didn't get any results ecxept ecxeptions

class SipgateService {

  static transactional = true

  def serviceMethod() {
    def sipgateService
    //def phoneNumber = 'XXXXXXXXXX' //phoneNumber according to E.164 specification
    //working alternative: 
    println "service"
    def phoneNumber = 'XXXXXXXXXX' 
    def result = sipgateService.sendSMS(phoneNumber, 'This is my Text to send!')
    result ?  'Sending Successful':'Sending failed'
    println "after service"

  }
}

请用一个例子来解释我。
非常感谢。

Please explain me with an example. thanks alot in advance.

推荐答案

如果您想从服务方法调用插件，您需要请执行以下操作：
$ b

If you want to call the plugin from a service method, you would need to do:

1. 更改您的服务的名称（因此它不被称为 SipgateService ）


2. 添加 def sipgateService 作为类定义，而不是一个方法

1. change the name of your service (so it isn't called SipgateService)
2. Add the def sipgateService as a class definition, not a method one

这是否工作？

class MySMSService {
  static transactional = true

  def sipgateService // This will be injected from the SMS plugin

  def serviceMethod() {
    println "service"
    def phoneNumber = 'XXXXXXXXXX' 
    def result = sipgateService.sendSMS(phoneNumber, 'This is my Text to send!')
    result ?  'Sending Successful':'Sending failed'
    println "after service"
  }
}

然后，从控制器中，在类级别定义到 MySMSService 的链接，并调用您的 serviceMethod 方法即：

Then, from a controller, define the link to MySMSService at class level, and call your serviceMethod method ie:

class MyController {
  def mySMSService  // this will be injected from your service

  // then, when you want to use it (from an action)

  def someAction = {
    ...
    mySMSService.serviceMethod()
    ...
  }
}
