Gzip Apache骆驼要求休息

Question

I am using apache camel for rest service calls from spring

Now we need to send the json request in our body to be passed in GZIP using apache camel. I tried by adding CONTENT_ENCODING as gzip, but it does not work. Please see the code

public void process(Exchange exchange) { exchange.setPattern(ExchangePattern.InOut); exchange.setProperty(Exchange.CHARSET_NAME, "UTF-8"); Message inMessage = exchange.getIn(); inMessage.setHeader(ACCEPT_HEADER, "application/json"); inMessage.setHeader(CONTENT_TYPE, "application/json"); inMessage.setHeader(Constants.ACCEPT_ENCODING, Constants.ACCEPT_ENCODING_TYPE); inMessage.setHeader(Exchange.CONTENT_ENCODING, "gzip"); inMessage.setBody(body);

In the camelContext.xml,

we have defined

 <route streamCache="true">
            <from uri="direct:setUpload" />
            <recipientList>
                <simple>cxfrs://{{uploadSample.url}}?throwExceptionOnFailure=false</simple>
            </recipientList>
            <unmarshal ref="sampleParser" />
        </route>

Do we need to set any other things to gzip the body JSON request

Please help how to correct this

You can try to convert json string to gzip before recipient list.

ByteArrayOutputStream out = new ByteArrayOutputStream();
GZIPOutputStream gzip = new GZIPOutputStream(out);
gzip.write(str.getBytes());
exchange.setBody(out.toString());
