SpringBoot框架使用（两种携带参数的get接口开发）

get请求携带参数一般有两种方式：第一种是url?key1=value1&key2=value2，第二种是url/value1/value2，所以两种方式分开来讲

1.url?key1=value1&key2=value2

@RequestMapping(value = "/get/with/param",method = RequestMethod.GET)
    public Map<String,Integer> getList(@RequestParam Integer start,
                                      @RequestParam Integer end){
        Map<String,Integer>  myList =new HashMap<>();
        myList.put("鞋",400);
        myList.put("衬衫",300);
        myList.put("T恤",200);

        return myList;

    }

运行Application，然后浏览器访问http://localhost:9527/get/with/param?start=1&end=2

2.url/value1/value2

@RequestMapping(value = "/get/with/param/{start}/{end}",method = RequestMethod.GET)
    public Map myGetList(@PathVariable Integer start,
                         @PathVariable Integer end){
        Map<String,Integer>  myList =new HashMap<>();
        myList.put("鞋",400);
        myList.put("衬衫",300);
        myList.put("T恤",200);

        return myList;
    }

Rerun Application，然后浏览器访问http://localhost:9527/get/with/param/1/2
