如何在Camel XML中为Exchange Header设置纽约时区的昨日日期时间？

Got it, let's tweak your Camel XML code to set the date/time 24 hours before the current time (still using New York's GMT-5 timezone) into the order_creation_date header.

Here's the modified working code:

<setHeader headerName="order_creation_date">
    <simple resultType="java.lang.String">
        ${date-with-timezone:now.minus(24, "hours"):GMT-5:MM-dd-yyyy HH:mm:ss}
    </simple>
</setHeader>

Quick Breakdown of the Change: #

• The core adjustment is swapping now with now.minus(24, "hours") — this uses Camel Simple language's built-in date arithmetic to subtract a full 24-hour interval from the current moment.
• We retain your original timezone (GMT-5) and date format (MM-dd-yyyy HH:mm:ss) so the output structure stays consistent with your initial setup.

This will populate the order_creation_date header with the exact datetime that occurred 24 hours prior to the current time, properly formatted for the New York timezone.
