### springboot webflux  参数传递（表单序列化） ###

**表单序列话传递的参数可用控制器处理，也可使用路由函数处理**

**控制器处理参数**

**HelloController**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(Person person){
            System.out.println(person);
    
            return person.toString();
        }
    
        @RequestMapping("/hello2")
        public String hello2(Mono<Person> person){
            person.subscribe(System.out::println);
    
            return "success";
        }
    
        @RequestMapping("/hello3")
        public Mono<Person> hello3(ServerWebExchange exchange){
            System.out.println("hello 3");
    
            return exchange.getFormData().map(map -> {
                String name=map.getFirst("name");
                Integer age=Integer.parseInt(Objects.requireNonNull(map.getFirst("age")));
                System.out.println("name："+name);
                System.out.println("age："+age);
    
                Person person=new Person();
                person.setName(name);
                person.setAge(age);
    
                return person;
            });
        }
    
        @RequestMapping("/hello4")
        public Mono<Person> hello4(ServerWebExchange exchange){
            System.out.println("hello 4");
    
            return exchange.getFormData().flatMap(map -> {
                String name=map.getFirst("name");
                Integer age=Integer.parseInt(Objects.requireNonNull(map.getFirst("age")));
                
                System.out.println("name："+name+"  "+"age："+age);
    
                Person person=new Person();
                person.setName(name);
                person.setAge(age);
                
                return Mono.just(person);
            });
        }
    }

**路由函数**

**CustomRouterConfig**

@Configuration
    public class CustomRouterConfig {
    
        @Bean
        public RouterFunction<ServerResponse> initRouterFunction(){
            return RouterFunctions.route()
                    .POST("/hello",serverRequest -> serverRequest.formData().flatMap(map -> {
                        String name=map.getFirst("name");
                        Integer age=Integer.parseInt(Objects.requireNonNull(map.getFirst("age")));
                        System.out.println("name："+name);
                        System.out.println("age："+age);
    
                        Person person=new Person();
                        person.setName(name);
                        person.setAge(age);
    
                        return ServerResponse.ok().bodyValue(person);
                    }))
                    .build();
        }
    }
