pringMVC 后端代码 如何用 @requestParam() 接收前台传过来的数组

 SpringMVC传递一维数组：传递数组类型时，需要在@requestParam()中添加value，否则会出现HTTP Status 400 - Required long[] parameter 'data' is not present错误。    例如： @RequestParam(value = "data[]")long[] data前端jsp代码：

var dataArr = new Array();for(var i = 0; i < 10; i++){dataArr.push(i);} $.ajax({url : "test/arrayParam.shtml",data : {"datas" : dataArr},dataType : "json",success : function(data) {alert(data);},async : false});}

后端JAVA代码：

package com.pyc.search.view.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;@Controller@RequestMapping("/test")public class TestController {@RequestMapping("/arrayParam")public @ResponseBodyint test1(@RequestParam(value = "datas[]") long[] datas) {return datas.length;}}
