springMVC ajax 提交数组到后台

js代码articlePage:function(){$("#gitPos").click(function(){var arr = [];arr.length = 0;var len = $(".tableList tbody tr").length;$(".tableList tbody tr").each(function(){arr.push( $(this).children().eq(0).attr("code") )});$.ajax({type:"POST",url:"/manage/posDisplace",data:{"str":arr},success:function(str){console.log(str);}});});},</span></span>

后台接收：

@RequestMapping("/posDisplace")@ResponseBodypublic Message changePlace(HttpServletRequest request){String[] str = request.getParameterValues("str[]");</span>return articleBiz.changePlace(str);}
