Question

I am trying to get hold of a file ( or a directory ) under /WEB-INF/.../

outside of a request. I need it in a bean loaded at server startup.

Answer 1

As long as your bean is declared in web application context you can obtain an instance of ServletContext (using ServletContextAware, or by autowiring).

Then you can access files in webapp directory either directly (getResourceAsStream(), getRealPath()), or using ServletContextResource.

EDIT by momo:

@Autowired
ServletContext servletContext;

... myMethod() { 
     File rootDir = new File( servletContext.getRealPath("/WEB-INF/myDIR/") );
}
