My first thought was to use an old style ServletContextListener contextInitialized() method and from there use an ELResolver to manually request the instance of my managed bean (thus forcing the initialization to happen). Unfortunately, I can’t use an ELResolver to trigger the initialization at this stage because the ELResolver needs a FacesContext and the FacesContext … Read more
Spring Boot does a lot of auto-configuration that may not be needed. So you may want to narrow down only auto-configuration that is needed for your app. To see full list of auto-configuration included, just run logging of org.springframework.boot.autoconfigure in DEBUG mode (logging.level.org.springframework.boot.autoconfigure=DEBUG in application.properties). Another option is to run spring boot application with –debug … Read more
You can have a global variable or a static class member. 1) static class member //BeforeMain.h class BeforeMain { static bool foo; }; //BeforeMain.cpp #include “BeforeMain.h” bool BeforeMain::foo = foo(); 2) global variable bool b = foo(); int main() { } Note this link – Mirror of http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.14 / proposed alternative – posted by Lundin.
sudo mv /filename /etc/init.d/ sudo chmod +x /etc/init.d/filename sudo update-rc.d filename defaults The script should now start on boot. Note that this method also works with both hard links and symbolic links (ln). At this point in the boot process PATH isn’t set yet, so it is critical that absolute paths are used throughout. But, … Read more
The following works for springboot 1.3 and above: As init.d service The executable jar has the usual start, stop, restart, and status commands. It will also set up a PID file in the usual /var/run directory and logging in the usual /var/log directory by default. You just need to symlink your jar into /etc/init.d like … Read more
I had the same issue in Win7 regarding running a script (.bat) at startup (When the computer boots vs when someone logs in) that would modify the network parameters using netsh. What ended up working for me was the following: Log in with an Administrator account Click on start and type “Task Scheduler” and hit … Read more
You need to plug it into the task scheduler, such that it is launched after login of a user, using a user account that has administrative access on the system, with the highest privileges that are afforded to processes launched by that account. This is the implementation that is used to autostart processes with administrative … Read more
Create a .bat file and put this inside: javaw -Xmx200m -jar C:\Path\to\jarfile\TheJar.jar Then put the .bat file into the windows startup folder. One more thing: There’s a difference between using java and javaw. While java is better when you are debugging an application, the application prints text or something like that, javaw is better when … Read more
The easiest way is to use Proc::Daemon. #!/usr/bin/perl use strict; use warnings; use Proc::Daemon; Proc::Daemon::Init; my $continue = 1; $SIG{TERM} = sub { $continue = 0 }; while ($continue) { #do stuff } Alternately you could do all of the things Proc::Daemon does: Fork a child and exits the parent process. Become a session leader … Read more
