Apache Camel HTTP display request and response

Question

I am using Apache Camel to load data from CSV file to a webservice. Is there anyway I can display request and response. Below is the route configuration..

I split and aggregate 100 items from array to be sent as POST body.

from(fileLocation)
.unmarshal().csv().bean(new CSVConverter(), "process")

.split(body())
.aggregate(constant(true), new GroupedBodyAggregationStrategy())
.completionSize(100)
.completionTimeout(1000)
.marshal().json(JsonLibrary.Jackson)

.setHeader("Authorization", simple(apiKEY))
.setHeader(Exchange.HTTP_METHOD, constant("POST"))
.setHeader(Exchange.HTTP_URI, simple(apiURL))
.setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
.to("https://serivceurl.com/abc");

Please let me know how can I display request and response with above route?

Answer 1

You can use camel log component to log headers; properties and body

ex:

.to("log:DEBUG?showBody=true&showHeaders=true")
.to("https://serivceurl.com/abc");
.to("log:DEBUG?showBody=true&showHeaders=true")

For more options pl refer: https://camel.apache.org/log.html

If you are planning to use CXF to invoke web service, out of the box logging feature can be used as below,

<cxf:bus>
  <cxf:features>
    <cxf:logging/>
  </cxf:features>
</cxf:bus>

If you take a look into the org.apache.camel.component.http.HttpProducer class you'll see that there is some logging implemented.

        try {
        if (LOG.isDebugEnabled()) {
            LOG.debug("Executing http {} method: {}", method.getName(), method.getURI());
        }
        int responseCode = executeMethod(method);
        LOG.debug("Http responseCode: {}", responseCode);

So if you configure your logging framework (like logback) to the correct LoggingLevel you'll see what the HTTP-Component exactly does. If you want to log it yourself you can try with the log component or the log dsl like mentioned in the other answer.
