Grails Mail 服务在 war 模式下无法与 guartz 调度程序一起使用

Question

我使用 quartz 调度程序在特定时间发送邮件:

static triggers = {
   cron name: 'DashboardReporting', cronExpression:"0 0 11,20 * * ?"
}

现在在执行内部，我使用 grails 异步插件发送邮件，该插件在运行应用程序模式下完美运行:

emailNotificationService.sendDashboardReportEmail(emaiListing, [model:model,XYZmodel:XYZmodel])

现在，当我出于开发目的运行应用程序并从本地计算机发送邮件时，这件事可以完美运行。

但是当我使用 run-war 运行相同的代码时，我得到了这个异常:

我使用了异步提供的默认 quartz 版本。另外值得注意的是，我无法直接注入(inject)异步邮件服务，因此我将其 Autowiring 为:

 @Autowired
AsynchronousMailService asyncMailService

但同样，这个东西在 run-app 和服务的其他许多使用情况下工作正常，只有在 war 模式下这个错误才会出现。

我也尝试了普通的邮件插件，但遇到了同样的问题。有什么建议吗？？

Answer 1

我知道这个问题已经有点老了，但是提供的答案在 grails 3.0.9 中对我不起作用。具体来说，它需要我设置一个全局 serverUrl 来覆盖为任何开发/测试/生产环境指定的任何内容。

下面，添加到 BootStrap.groovy 就可以了。看来 grails 中的 LinkGenerator 初始化实际上是罪魁祸首，而不是邮件插件。

LinkGenerator grailsLinkGenerator = grailsApplication.mainContext.getBean("grailsLinkGenerator")
grailsLinkGenerator.configuredServerBaseURL = 
                    grailsLinkGenerator.configuredServerBaseURL ?:
                         grailsApplication.config.grails.serverUrl
