Spring ApplicationContext - Resource leak: 'context' is never closed

Question

In a spring MVC application, I initialize a variable in one of the service classes using the following approach:

ApplicationContext context = 
         new C         


        

Answer 1

You make the context a static variable, which means that the context is available to all the static methods in the class, and not limited to the scope of the main method anymore. So the tool can't assume that it should be closed at the end of the method anymore, so it doesn't issue the warning anymore.

public class MainApp {
    private static ApplicationContext context;
    public static void main(String[] args) {
          context = 
                 new ClassPathXmlApplicationContext("Beans.xml");

          HelloWorld obj = (HelloWorld) context.getBean("helloWorld");

          obj.getMessage();

       }
}
