SpringMVC 参数中接收数组、List写法

@RequestMapping("/hello")
    public String test(String name,@RequestBody List<ForListReceive> list) {
        /**
         * 接收List的条件
         * 1、使用JSON格式数据，如[{"a":"a","b":"b"}] 放在RequestBody中传递
         * 2、RequestHeader中需要有 Content-Type: application/json;charset=utf8
         * 3、需要在参数前加上@RequestBody
         */

        System.out.println(list.get(0).getA());
        return list.size()+":"+name;
    }

    @RequestMapping("/hi")
    public String hi(@RequestParam("list") List<String> list) {
        /**
         * 接收List<String>
         * 1、Request Parameters中list=a,b,c 
         * 2、必须写上@RequestParam("list")
         */
        System.out.println(list.get(0));
        return list.size()+"";
    }

    @RequestMapping("/hey")
    public String hey(String[] list) {
        /**
         * 接收数组
         * 1、Request Parameters中list=a,b,c 即可成功接收
         */
        System.out.println(list[0].toString());
        System.out.println(list[1].toString());
        return list.length+"";
    }

public void setA(String a) {
