我试图弄清楚如何用邮件发送来发送HTML邮件。我被困住了，并得到“没有方法签名:适用于参数类型:(空)值:[空]”，这是我试图传递给电子邮件的请求ID变量。
我的工作在下面

<body>
<p>Thank you for submitting your change of program request. You will receive an email when it has been approved or denied.</p>
<p>record: ${requestId}</p>
"<p>Thank you.</p>"

最佳答案
问题之一是，您的GSP似乎期望使用名为requestId的模型变量，但是EmailReceivedRequestExternalTaskJob正在创建名为param1的模型变量:
html view: "/studentApprovalRequest/AcknowledgementEmail", model: [param1: requestId]
html view: "/studentApprovalRequest/AcknowledgementEmail", model: [requestId: requestId]
