SpringMVC参数的传递之如何接收List数组类型的数据

$(function () {
    var obj={};
    obj.name="李四";
    obj.nums=[1,2,3];
    $.ajax({
        url: "/param/test1",
        type:"POST",
        contentType:"application/x-www-form-urlencoded",
        data:obj,
        dataType:"json",
        success:function(data){
        }
    })
})

 	@RequestMapping(value = "/test1", method = RequestMethod.POST)
    @ResponseBody
    private String Test1(String name,@RequestParam("nums[]") Integer[] nums) {
        System.out.println(name);
        for(int i=0;i<nums.length;i++){
            System.out.println(nums[i]);
        }
        return "success";
    }

	@RequestMapping(value = "/test1", method = RequestMethod.POST)
    @ResponseBody
    private String Test1(String name,@RequestParam("nums[]") List<Integer> nums) {
        System.out.println(name);
        System.out.println(nums);
        return "success";
    }

public class User {
