Example 81 with WebApplicationContext

use of org.springframework.web.context.WebApplicationContext in project spring-framework by spring-projects.

the class WebApplicationContextUtils method findWebApplicationContext.

	 * <p>Note that {@code DispatcherServlet}'s exposure of its context can be
	 * controlled through its {@code publishContext} property, which is {@code true}
	 * by default but can be selectively switched to only publish a single context
	 * despite multiple {@code DispatcherServlet} registrations in the web app.
