先看一遍官方文档

通过注解的方式了解到，与 spirng mvc 不同之处在于Controller 方法的返回值（此外还有参数列表与方法体）不太一样。

@RestController@RequestMapping("/users")public class MyRestController {	@GetMapping("/{user}")	public Mono
    
      getUser(@PathVariable Long user) {		// ...	}	@GetMapping("/{user}/customers")	public Flux
     
       getUserCustomers(@PathVariable Long user) {		// ...	}	@DeleteMapping("/{user}")	public Mono
      
        deleteUser(@PathVariable Long user) {		// ...	}}
      
     
    

那么函数式呢？需要自己 编写路由 与 handler

@Configurationpublic class RoutingConfiguration {	@Bean	public RouterFunction
    
      monoRouterFunction(UserHandler userHandler) {		return route(GET("/{user}").and(accept(APPLICATION_JSON)), userHandler::getUser)				.andRoute(GET("/{user}/customers").and(accept(APPLICATION_JSON)), userHandler::getUserCustomers)				.andRoute(DELETE("/{user}").and(accept(APPLICATION_JSON)), userHandler::deleteUser);	}}@Componentpublic class UserHandler {	public Mono
     
       getUser(ServerRequest request) {		// ...	}	public Mono
      
        getUserCustomers(ServerRequest request) {		// ...	}	public Mono
       
         deleteUser(ServerRequest request) {		// ...	}}
