### springboot webflux 参数传递（表单传递） ###

**表单传递的参数可使用注解（@RequestParam）读取，也可使用路由函数处理**

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**注解：@RequestParam**

@RestController
    public class HelloController {
    
        @RequestMapping("/get2")
        public String hello2(@RequestParam String name){
            System.out.println("name："+name);
    
            return name;
        }
    
        @RequestMapping("/get3")
        public String hello3(ServerWebExchange exchange){
            String name=exchange.getRequest().getQueryParams().getFirst("name");
            System.out.println("name："+name);
    
            return name;
        }
    
        @RequestMapping("/get4")
        public Mono<String> hello4(ServerHttpRequest request){
            String name=request.getQueryParams().getFirst("name");
            System.out.println("name："+name);
    
            assert name != null;
            return Mono.just(name);
        }
    }

**路由函数**

public class CustomRouterConfig {
    
        @Bean
        public RouterFunction<ServerResponse> initRouterFunction(){
            return RouterFunctions.route()
                    .POST("/hello2",serverRequest -> {
                        String name=serverRequest.exchange().getRequest().getQueryParams().getFirst("name");
                        System.out.println("name："+name);
    
                        assert name != null;
                        return ServerResponse.ok().bodyValue(name);
                    })
                    .build();
        }
    }
