Example 22 with HandlerInterceptor

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

the class AbstractHandlerMapping method getCorsHandlerExecutionChain.

/**

	 * HandlerInterceptor that makes CORS-related checks and adds CORS headers.

Example 23 with HandlerInterceptor

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

the class AbstractHandlerMapping method getMappedInterceptors.

Example 24 with HandlerInterceptor

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

the class AbstractHandlerMapping method getHandlerExecutionChain.

/**
	 * Build a {@link HandlerExecutionChain} for the given handler, including
	 * applicable interceptors.
	 * <p>The default implementation builds a standard {@link HandlerExecutionChain}
	 * with the given handler, the handler mapping's common interceptors, and any
	 * {@link MappedInterceptor}s matching to the current request URL. Interceptors
	 * are added in the order they were registered. Subclasses may override this
	 * in order to extend/rearrange the list of interceptors.
	 * <p><b>NOTE:</b> The passed-in handler object may be a raw handler or a
	 * pre-built {@link HandlerExecutionChain}. This method should handle those
	 * two cases explicitly, either building a new {@link HandlerExecutionChain}
	 * or extending the existing chain.
	 * <p>For simply adding an interceptor in a custom subclass, consider calling
	 * {@code super.getHandlerExecutionChain(handler, request)} and invoking
	 * {@link HandlerExecutionChain#addInterceptor} on the returned chain object.
	 * @param handler the resolved handler instance (never {@code null})
	 * @param request current HTTP request
	 * @return the HandlerExecutionChain (never {@code null})
