Viewing properties defined in a properties file
If your project contain properties files, you may want to view their content. For instance, when we created the flight-app Roo project earlier, a log4j.properties file containing logging configuration was also created. In this recipe, we will look at the properties list command to view the contents of the log4j.properties file.
Getting ready
Start the Roo shell from C:\roo-cookbook\ch01-recipe directory, which contains the flight-app Roo project.
How to do it...
To view the contents of a properties file, the properties list command requires a path to the properties file and its name. The following properties list command displays the contents of the log4j.properties file:
roo> properties list --name log4j.properties --path SRC_MAIN_RESOURCES log4j.appender.R = org.apache.log4j.RollingFileAppender log4j.appender.R.File = application.log ... log4j.logger.sample.roo.flightapp = DEBUG log4j.rootLogger = DEBUG, stdout
How it works...
The
Properties file add-on is responsible for processing the properties list command. The following table describes the arguments it accepts:
