使用Exchange物业骆驼DSL＆QUOT;到＆QUOT; [英] Use Exchange Property in Camel DSL "to"

问题描述

我想设置一个骆驼交易所属性，然后保存文件时使用此属性。在我的骆驼DSL我有以下几点：

I want to set a property on a Camel Exchange and then use this property when saving the file. In my camel dsl I have the following:

.process(processorToSetExhangeProperty)  // sets the property <uid> on the exchange
.to("file:/tmp?fileName=file-" + property("uid") + ".xml")

该文件被保存为：

The file is being saved as:

"file-property{uid}.xml" though

我的处理器如下：

My processor is as follows:

    @Override
    public void process(Exchange exchange) throws Exception {
        UUID uuid = UUID.randomUUID();
        exchange.setProperty("uid",
                uuid.toString());
        exchange.setOut(exchange.getIn());
    }

什么可能会错误或我怎么能做到这一点有什么想法？

Any thoughts on what may be going wrong or how I can achieve this?

推荐答案

在来中的骆驼是不是在运行时PTED间$ P $。

The "to" in the Camel is not interpreted at runtime.

如果要动态构建你的URI，您应该使用recipientList。
请参见 http://camel.apache.org/怎么办，我使用的动态-URI-在to.html

You should use recipientList if you want to construct your URI dynamically. See http://camel.apache.org/how-do-i-use-dynamic-uri-in-to.html
