在开发中有时候我们有时候会将JSONArray转化为list的需求JSONArray jsonArray = [{"colName":"2017年01月","addNum":"539","totalNum":"8395"},{"colName":"2017年02月","addNum":"447","totalNum":"8888"},{"colName":"2017年03月","addNum":"75","totalNum":"8963"},{"colName":"2017年04月","addNum":"68","totalNum":"9031"},{"colName":"2017年05月","addNum":"7050","totalNum":"16355"},{"colName":"2017年06月","addNum":"19","totalNum":"16374"}];我们可以定义一个类去接收,类的字段就是colName.addNum.totalNum[java] view plain copy print?package com.jbns.easymaster.web.asset.vo;import java.io.Serializable;/*** 设备增量趋势分析 导出用实体类* @author www**/public class DeviceAddDyn implements Serializable{/*** 版本信息*/private static final long serialVersionUID = -2349692708851483212L;/*** 列名称*/private String colName;/*** 添加数量*/private String addNum;/*** 总数量*/private String totalNum;public String getColName() {return colName;}public void setColName(String colName) {this.colName = colName;}public String getAddNum() {return addNum;}public void setAddNum(String addNum) {this.addNum = addNum;}public String getTotalNum() {return totalNum;}public void setTotalNum(String totalNum) {this.totalNum = totalNum;}}然后通过deviceList = (List<DeviceAddDyn>) jsonArray.toCollection(jsonArray, DeviceAddDyn.class);这个方法就将一段JSONArray转化为list集合,对象为DeviceAddDyn
