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

Yes, interface ApplicationContext doesn't have close() method, so I like to use class AbstractApplicationContext to use that close method explicitly and also here you can use your Spring Application configuration class using annotation instead of XML type.

AbstractApplicationContext context = new AnnotationConfigApplicationContext(SpringAppConfig.class);
Foo foo = context.getBean(Foo.class);

//do some work with foo

context.close();

your Resource leak: 'context' is never closed warning is gone now.
