The RequestDumperFilter is a Tomcat log filter used to log HTTP Requests and Responses.
I have set up the org.apache.catalina.filters.RequestDumperFilter for Tomcat according to this documentation.
As the log shows, the message headers are being logged, but the message body is omitted in the log for both HTTP Requests and Responses (tested with various messages)
The documentation mentions the logging.properties setting needed to log the body:
## The level must be set at least to INFO. If you want to dump the body also, set it to FINEST
The org.apache.catalina.filters.RequestDumperFilter class in the Apache SVN repository does not appear to have the functionality to log message body.
${catalina.base}/conf/logging.properties:
handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler, 1request-dumper.org.apache.juli.FileHandler
...
# To this configuration below, 1request-dumper.org.apache.juli.FileHandler
# also needs to be added to the handlers property near the top of the file
1request-dumper.org.apache.juli.FileHandler.level = FINEST
1request-dumper.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1request-dumper.org.apache.juli.FileHandler.prefix = request-dumper.
1request-dumper.org.apache.juli.FileHandler.formatter = org.apache.juli.VerbatimFormatter
org.apache.catalina.filters.RequestDumperFilter.level = FINEST
org.apache.catalina.filters.RequestDumperFilter.handlers = \
1request-dumper.org.apache.juli.FileHandler
