Jersey Logging supports the logging request and response via internal client and server filters, which are
configured and registered by LoggingFeature 's properties. LoggingFeature
has been introduced in Jersey 2.23 version and deprecates an older LoggingFilter.
LoggingFeature might be discovered by
auto-discoverable mechanism
or initialized by registering on client or server components. Client or server logging filter is initialized
depending on which context is LoggingFeature registered with.
Configurable options
Logger nameDefines a logger used to log request and response messages.
Default value is LoggingFeature.DEFAULT_LOGGER_NAME.
Logger levelDefines level that will be used to log messages by logging filters. Messages will be logged only if the effective level of the logger allows it.
Default value is LoggingFeature.DEFAULT_LOGGER_LEVEL.
VerbosityVerbosity determines how detailed message will be logged. See LoggingFeature.Verbosity javadoc.
The lowest verbosity LoggingFeature.Verbosity.HEADERS_ONLY will log only request/response headers.
The medium verbosity (LoggingFeature.Verbosity.PAYLOAD_TEXT) will log request/response headers, as well as an entity if considered a readable text. The entity is considered a readable text, if MediaType is
text/*or is one ofapplication/atom+xmlapplication/jsonapplication/svg+xmlapplication/x-www-form-urlencodedapplication/xhtml+xmlapplication/xml
The highest verbosity LoggingFeature.Verbosity.PAYLOAD_ANY will log all types of an entity (besides the request/response headers.
Note that the entity is logged up to the specified maximum number of bytes (see LoggingFeature.LOGGING_FEATURE_MAX_ENTITY_SIZE).
Default value is LoggingFeature.DEFAULT_VERBOSITY.
Maximum entity sizeMaximum number of entity bytes to be logged (and buffered) - if the entity is larger, logging filter will print (and buffer in memory) only the specified number of bytes and print "...more..." string at the end. Negative values are interpreted as zero.
Default value LoggingFeature.DEFAULT_MAX_ENTITY_SIZE.
The feature is enabled on when auto-discoverable mechanism is not disabled and at least one of the feature's
property is set. For enabling client or server logging filter one of the
common properties or
_CLIENT
suffixed properties, or
_SERVER properties
respectively.
An example of initializing server-side logging with the highest verbosity.
Example 22.1. Logging on the client side
ClientConfig clientConfig = new ClientConfig();
clientConfig.property(LoggingFeature.LOGGING_FEATURE_VERBOSITY_CLIENT, LoggingFeature.Verbosity.PAYLOAD_ANY);
Client client = ClientBuilder.newClient(clientConfig);
The LoggingFeature might be registered explicitly on ResourceConfig for
server-side logging or on Client for client-side logging.
Example 22.2. Register LoggingFeature via constructor
ResourceConfig config = new ResourceConfig(HelloWorldResource.class);
config.register(new LoggingFeature(LOGGER, LoggingFeature.Verbosity.PAYLOAD_ANY));
Following examples demonstrate registering LoggingFeature on server-side with default
values and values defined by one of the public constructors (see LoggingFeature).
Example 22.3. Register LoggingFeature class
ResourceConfig config = new ResourceConfig(HelloWorldResource.class);
config.register(LoggingFeature.class);
