### springboot webflux 参数传递（json传递） ###

**json传递的参数数据可用注解读取，也可用路由函数处理**

**注解：@RequestBody**

**controller 层**

**HelloController**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello2")
        public String hello2(@RequestBody Person person){
            System.out.println(person);
    
            return person.toString();
        }
    
        @RequestMapping("/hello3")
        public Mono<Person> hello3(@RequestBody Mono<Person> person){
            return person.doOnNext(System.out::println);
        }
    
        @RequestMapping("/hello4")
        public Flux<Person> hello4(@RequestBody Flux<Person> person){
            return person.doOnNext(System.out::println);
        }
    }

**路由函数**

**CustomRouterConfig**
