Logging

Refer to Quarkus Logging guide for basic information about logging on Quarkus, such as

Payload logging

History

Since Quarkus CXF 2.6.0, the payload logging functionality is available via io.quarkiverse.cxf:quarkus-cxf extension. Before 2.6.0, it was available through a separate extension io.quarkiverse.cxf:quarkus-cxf-rt-features-logging which is now deprecated and will be removed in the future.

The payload logging functionality is implemented primarily through the org.apache.cxf.ext.logging.LoggingFeature class.

There are several ways how you can set the feature on a client or service endpoint.

Configuring payload logging through configuration properties

Global settings

The global logging options exist since Quarkus CXF 2.6.0. If enabled via quarkus.cxf.logging.enabled = true, Quarkus CXF creates a global LoggingFeature instance and sets it on every client and service endpoint in the application. The global settings can be overriden on the client or service endpoint level.

application.properties
# Global settings
quarkus.cxf.logging.enabled = true
quarkus.cxf.logging.pretty = true

All logging configuration options are listed on quarkus-cxf reference page.

All logging properties mentioned on this page are runtime configuration options. Hence you can pass them when starting the application without having to rebuild it. It can be done either by passing a system property on the command line (e.g. -Dquarkus.cxf.logging.enabled=true) or by setting an environment variable (e.g. export QUARKUS_CXF_LOGGING_ENABLED=true).

Per client and per service endpoint settings

Since Quarkus CXF 2.5.0, the LoggingFeature can be configured and attached to a client or a service endpoint declaratively by setting the appropriate options in application.properties:

application.properties
# For a service:
quarkus.cxf.endpoint."/hello".logging.enabled = true
quarkus.cxf.endpoint."/hello".logging.pretty = true
# For a client:
quarkus.cxf.client.hello.logging.enabled = true
quarkus.cxf.client.hello.logging.pretty = true

All logging configuration options are documented on quarkus-cxf reference page:

Alternative ways of adding a LoggingFeature to a client or service

To attach an instance with default settings, you can do one of the following:

  1. In application.properties:

    # For a service:
quarkus.cxf.endpoint."/hello".features=org.apache.cxf.ext.logging.LoggingFeature
# For a client:
quarkus.cxf.client."myClient".features=org.apache.cxf.ext.logging.LoggingFeature

    There is an example in Your first SOAP Web service chapter of the User guide.

    or alternatively

  2. Use the @Features annotation of CXF:

    @org.apache.cxf.feature.Features (features = {"org.apache.cxf.ext.logging.LoggingFeature"})
@WebService(endpointInterface = "org.acme.SayHi", targetNamespace = "uri:org.acme")
public class SayHiImplementation implements SayHi {
   public long sayHi(long arg) {
       return arg;
   }
   //...
}

Producing a custom LoggingFeature bean

If you need some custom logic to setup the LoggingFeature, you can produce a named LoggingFeature bean:

import org.apache.cxf.ext.logging.LoggingFeature;
import jakarta.enterprise.context.ApplicationScoped;
import jakarta.enterprise.inject.Produces;

class Producers {

    @Produces
    @ApplicationScoped
    @Named("limitedLoggingFeature") // "limitedLoggingFeature" is redundant if the name of the method is the same
    LoggingFeature limitedLoggingFeature() {
        LoggingFeature loggingFeature = new LoggingFeature();
        loggingFeature.setPrettyLogging(true);
        loggingFeature.setLimit(1024);
        return loggingFeature;
    }
}

Then you can refer to it by its name prefixed with # in application.properties:

# For a service:
quarkus.cxf.endpoint."/hello".features = #limitedLoggingFeature
# For a client:
quarkus.cxf.client.hello.features = #limitedLoggingFeature
