前端ajax傳數組，後端spring接受

ajax

	
    		$.ajax({
    			url: path + "/overtime/deleteByBatch.action?t="+new Date().getTime(),
    			type: "POST",
    			data:{"overtimeids" : arr},
    			dataType: "JSON",
    			success: function(data) {
    				if(data.code == 200){
    					alert(data.msg);
    					location.href = path+"/overtime/list.action";
    				}else{
    					alert("刪除失敗");
    				}

spring

	@RequestMapping("deleteByBatch.action")
	@ResponseBody
	public OAResult<?> deleteByBatch(@RequestParam(value="overtimeids[]")String[] overtimeids ){
		System.out.println("ids is:"+overtimeids);
		return os.deleteOvertimesByBatch(overtimeids);
	}

the key code is @RequestParam(value=“overtimeids[]”)!!!
