Make use of a time-based scheduler Cron, which is available on Debian (as well as on other Unix-like operating systems). Quartz offers a seamless integration with Java applications. Scheduling a particular script (e.g. restarting server) can be easily done using Cron expressions in form of a string consisting of five or six fields (separated by white space), which are respectively responsible for: minutes, hours, day of month, month, day of week, year.

1) Implement a procedure to restart server (e.g. integrated in Java application or through system script).
2) Make use of Quartz to provide Cron functionality to Java application, in particular to make use of Cron expressions.
3) Provide an option for (privileged/administrator) users to manage Cron expression string for restarting server in web interface.
4) Explain in a short summary the principle of functioning of Cron expressions, providing examples of the most common usages.

If Hyper-V was manually uninstalled or virtualization was disabled, Docker for Windows will not start.
A solution is to enable the virtualization on your machine. In order to do that you have to access the BIOS, select the Intel Virtual Technology and enable the virtualization.
Save the changes and restart the computer, then Docker can be started and used for deploying.

I searched for another encoder and found Google’s “GSON” project. I used it to encode the DTO “manually” (without Spring) into a String, sent it to the server and decoded the string there again via GSON (without Spring) into the original object. This time it worked as expected.
