springmvc以list形式接收数组

前端代码：

var a = [ 1, 2, 3, 4, 5, 6, 7 ];$.ajax({url : "/Udian/alipayAppPay/withdraw_cash_audit",type : "post",dataType : "json",data : {billIds : a},success : function(data) {console.log(1);}});

后台代码：

@RequestMapping(value = "/withdraw_cash_audit", method = RequestMethod.POST)public void withdrawCash(@RequestParam("billIds[]") List<Integer> billIds) {for (Integer integer : billIds) {System.out.println(integer);}}

输出:
