红帽全球峰会21.12. 使用文件夹和文件名共同购买
当 Camel 生成文件时（写入文件）有一些影响如何设置您选择的文件名。默认情况下，Camel 将使用消息 ID 作为文件名，并且由于消息 ID 通常是唯一生成的 ID，因此您将以文件名开头，例如： ID-MACHINENAME-2443-1211718892437-1-0。如果不需要此类文件名，则必须在 CamelFileName 消息标头中提供一个文件名。还可以使用恒定的 Exchange.FILE_NAME。
以下示例代码使用消息 ID 作为文件名生成文件：
from("direct:report").to("file:target/reports");
from("direct:report").to("file:target/reports");
要使用 report.txt 作为您必须执行的文件名：
from("direct:report").setHeader(Exchange.FILE_NAME, constant("report.txt")).to( "file:target/reports");
from("direct:report").setHeader(Exchange.FILE_NAME, constant("report.txt")).to( "file:target/reports");-
与以上地址相同，但使用
CamelFileName：
from("direct:report").setHeader("CamelFileName", constant("report.txt")).to( "file:target/reports");
from("direct:report").setHeader("CamelFileName", constant("report.txt")).to( "file:target/reports");以及用于使用 fileName URI 选项在端点上设置文件名的语法。
from("direct:report").to("file:target/reports/?fileName=report.txt");
from("direct:report").to("file:target/reports/?fileName=report.txt");
