java - 在Quartz中发送邮件时，在java.net.URI $ Parser.parse()中使NPE失效

我们有预定的开票服务，我们将发票发送到客户的电子邮件中。

asynchronousMailService.sendMail {
            multipart true
            to emailTo.split("[,;]")
            bcc bccString
            from fromString
            subject subjectString
            html view:'/email/invoiceEmailTemplate',
                    model: [companyName: companyName, customerFirstName:  order.customer.firstName,
                            xeroInvoiceId: invoice.invoiceNumber, invoiceTotal: order.totalAmount,
                            invoiceUrl: invoiceUrl,
                            currencyCode: invoice.currencyCode, dueDate: invoice.dueDate]
            attachBytes invoice.invoiceNumber+".pdf" , 'application/pdf', invoiceBytes
        }

导致此错误:

上面的错误日志仅在生产服务器中发生，并且无法在本地计算机和开发服务器上进行复制。

有任何想法吗？

最佳答案

我在这里回答了这个问题:Grails Mail service not working with guartz scheduler in war mode

这是AsyncMail无法获取服务器的URL。最简单的事情是通过grails.serverURL config属性对其进行配置。
