Example 1 with HandlerFunction

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

the class HandlerFunctionAdapter method handle.

@Nullable
@Override
public ModelAndView handle(HttpServletRequest servletRequest, HttpServletResponse servletResponse, Object handler) throws Exception {
    WebAsyncManager asyncManager = getWebAsyncManager(servletRequest, servletResponse);
    ServerRequest serverRequest = getServerRequest(servletRequest);
    ServerResponse serverResponse;
    if (asyncManager.hasConcurrentResult()) {
        serverResponse = handleAsync(asyncManager);
    } else {
        HandlerFunction<?> handlerFunction = (HandlerFunction<?>) handler;
        serverResponse = handlerFunction.handle(serverRequest);
    }
    if (serverResponse != null) {
        return serverResponse.writeTo(servletRequest, servletResponse, new ServerRequestContext(serverRequest));
    } else {
        return null;
    }
}

Example 2 with HandlerFunction

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

the class RouterFunctionMappingTests method normal.

@Test
void normal() throws Exception {
    HandlerFunction<ServerResponse> handlerFunction = request -> ServerResponse.ok().build();
    RouterFunction<ServerResponse> routerFunction = request -> Optional.of(handlerFunction);
    RouterFunctionMapping mapping = new RouterFunctionMapping(routerFunction);
    mapping.setMessageConverters(this.messageConverters);
    MockHttpServletRequest request = createTestRequest("/match");
    HandlerExecutionChain result = mapping.getHandler(request);
    assertThat(result).isNotNull();
    assertThat(result.getHandler()).isSameAs(handlerFunction);
}
