Block of code that I need to run everytime my servlet container starts up

Question

I have some static block of content which need to load on startup of Spring MVC application.

static{
    // Added to use in the Log4J.xml file
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    System.setProperty("current.date", dateFormat.format(new Date()));
}

This 'current.date' property I am doing to use in the log4j.xml to set the current date. I don't know where to put this into Spring's context so that It can call every time when user runs the application.

In the main bean, implement the InitializingBean interface. In this interface methods, put your above statements. They will run before initializing the bean.

I would suggest following:

Put this code in the init() of a Servlet.
Configure this servlet in web.xml.
You can decide the order of loading (<load-on-startup/>) this servlet relative to other servlets.
When the container loads, it initializes the servlet and calls its init() method executing the initialization code.
