好吧，我咬了子弹。我创建了一个Java POJO

package com.wufoo.camel;

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;

import org.apache.log4j.Logger;

public class PayloadEncoder {
    public String getEncodedBody(String body) throws UnsupportedEncodingException {
        Logger mylogger = Logger.getLogger("log4j.logger.org.apache.camel");
        mylogger.info("Appending payload and URL Encoding");
        String encodedBody = new StringBuffer()
            .append("payload=")
            .append(URLEncoder.encode(body, "UTF-8")).toString();
        return encodedBody;
    }
}

然后将其注入到上下文中

<bean id="payloadEncoder" class="com.wufoo.camel.PayloadEncoder" />

最后用一个变换来编码尸体

<transform>
    <method bean="payloadEncoder" method="getEncodedBody"/>
</transform>

那很好。如果有人能告诉我这种方法有什么问题，请告诉我。

你也可以使用groovy语言，像这样：

<?xml version="1.0" encoding="UTF-8"?>
    <blueprint
    xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
    http://www.osgi.org/xmlns/blueprint/v1.0.0
    http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="file:camel/input"/>
            <log message="Moving ${file:name} to the output directory"/>
            <setBody>
                <groovy>
                    "name=" + URLEncoder.encode(request.getBody(String.class));
                </groovy>   
            </setBody>
            <to uri="file:camel/output"/>
        </route>
    </camelContext>
</blueprint>
