获取前端传递的任意key-value

获取前端传递的任意key-value，可以是多个。
不需要预先知道对方具体传什么。
post和get两种方法：

package com.nio.rd.algorithm.deploy.server.controller;

import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;



@RestController
@RequestMapping(value = "/test")
public class TestController {

    @RequestMapping(value = "/get", method = RequestMethod.GET, produces = "application/json; charset=utf-8")
    public void getTest(HttpServletRequest request) {

        System.out.println("------getTest------");

        Map map = request.getParameterMap();

        Set keySet = map.keySet();
        for (String k : keySet) {
            String s = Arrays.toString(map.get(k));
            String v = s.substring(1, s.length() - 1);
            System.out.println(k + ": " + v);
        }

    }


    @RequestMapping(value = "/post", method = RequestMethod.POST, produces = "application/json; charset=utf-8")
    public void postTest(@RequestBody HashMap body,
                        HttpServletRequest request) {

        System.out.println("------postTest------");

        Set keySet = body.keySet();
        for (String k : keySet) {
            System.out.println(k);
            System.out.println(body.get(k));
        }

        System.out.println(body.toString());

    }

}
