前台AJAX传数组后台的java接收

前台AJAX传数组，后台的java接收（后台接收前端发送的数组类型数据）两种解决方法

第一种方法，前端将数组通过JSON.stringify()方法转换为json格式数据，后台将接收的json数据转换为数组

function search() {            var equiNames = JSON.stringify($("#equiNames").val());            var startDate = $('#daterange-btn span').text().substring(0, 10);            var endDate = $('#daterange-btn span').text().substring(13);            $.ajax({                url : "dataAcquisition/report",                type : "post",                dataType : "json",                data : {                    "equiNames" : equiNames,                    "startDate" : startDate,                    "endDate" : endDate                },                success : function(result) {                    ……                    }                }            });        }

@RequestMapping("/report")    public void report(String equiNames, String startDate, String endDate, HttpServletRequest request,            HttpServletResponse response) throws ExecutionException, InterruptedException, IOException, ParseException {        //将接收的json数据转换为数组        List<String> equiNameList = new Gson().fromJson(equiNames, new TypeToken<List<String>>() {        }.getType());        List<DataAcquisitionVo> resultList = dataAcquisitionService.report(equiNameList, startDate, endDate);        response.setContentType("application/json; charset=UTF-8");        response.getWriter().write(new Gson().toJson(resultList));    }

第二种方法，前端通过设置traditional属性为true直接传递数组 */,后台通过对象接收

function search() {            var equiNames = JSON.stringify($("#equiNames").val());            var startDate = $('#daterange-btn span').text().substring(0, 10);            var endDate = $('#daterange-btn span').text().substring(13);            $.ajax({                url : "dataAcquisition/report",                type : "post",                dataType : "json",                traditional : true,//用传统方式序列化数据                data : {                    "equiNames" : equiNames,                    "startDate" : startDate,                    "endDate" : endDate                },                success : function(result) {                    ……                    }                }            });        }

对象

@RequestMapping("/report")    public void report(ReportParaVo rp, HttpServletRequest request, HttpServletResponse response)            throws ExecutionException, InterruptedException, IOException, ParseException {                List<DataAcquisitionVo> resultList = dataAcquisitionService.report(rp);        response.setContentType("application/json; charset=UTF-8");        response.getWriter().write(new Gson().toJson(resultList));    }

import java.util.List;public class ReportParaVo {    private List<String> equiNames;    private String startDate;    private String endDate;    public List<String> getEquiNames() {        return equiNames;    }    public void setEquiNames(List<String> equiNames) {        this.equiNames = equiNames;    }    public String getStartDate() {        return startDate;    }    public void setStartDate(String startDate) {        this.startDate = startDate;    }    public String getEndDate() {        return endDate;    }    public void setEndDate(String endDate) {        this.endDate = endDate;    }}

第二种方法效果如图所示
