Example 1 with FrameworkServlet

use of org.springframework.web.servlet.FrameworkServlet in project spring-framework by spring-projects.

the class AbstractDispatcherServletInitializer method registerDispatcherServlet.

/**

	 * {@link #getServletName()}, initializing it with the application context returned
	 * from {@link #createServletApplicationContext()}, and mapping it to the patterns
	 * returned from {@link #getServletMappings()}.
	 * <p>Further customization can be achieved by overriding {@link
	 * #customizeRegistration(ServletRegistration.Dynamic)} or
	 * {@link #createDispatcherServlet(WebApplicationContext)}.
	 * @param servletContext the context to register the servlet against
