java - 如何在 freemarker 中将日期转换为字符串？

Question

我就是这样做的..

<#assign createdOn='${receipt.arPaymDate}'>
${createdOn?datetime("MMM dd yyyy HH:mm:ss 'GMT'Z")?date}

但我遇到了异常

Can't convert the date-like value to string because it isn't known if it's a date (no time part), time or date-time value. The blamed expression: ==> receipt.arPaymDate [in template "WEB-INF/ftl/receiptPdf.ftl" at line 22, column 47]

感谢各位

您可能需要首先初始化日期格式

<#setting date_format="dd-MM-yyyy">

<#assign createdOn='${receipt.arPaymDate}'> 
${createdOn?datetime("MMM dd yyyy HH:mm:ss 'GMT'Z")?date}
