public class WebSocketHandlerMapping extends org.springframework.web.servlet.handler.SimpleUrlHandlerMapping implements org.springframework.context.SmartLifecycle
Extension of SimpleUrlHandlerMapping with support for more precise mapping of WebSocket handshake requests to handlers of type WebSocketHttpRequestHandler. Also delegates Lifecycle methods to handlers in the SimpleUrlHandlerMapping.getUrlMap() that implement it.

  • Method Details

    • setWebSocketUpgradeMatch

      public void setWebSocketUpgradeMatch(boolean match)
      When this is set, if the matched handler is WebSocketHttpRequestHandler, ensure the request is a WebSocket handshake, i.e. HTTP GET with the header "Upgrade:websocket", or otherwise suppress the match and return null allowing another HandlerMapping to match for the same URL path.
      Parameters:
      match - whether to enable matching on "Upgrade: websocket"
