在開發(fā)中有時(shí)候我們有時(shí)候會(huì)將JSONArray轉(zhuǎn)化為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"}];
我們可以定義一個(gè)類去接收,類的字段就是colName.addNum.totalNum

[java] view plain copy print?
package com.jbns.easymaster.web.asset.vo;

import java.io.Serializable;

/**
* 設(shè)備增量趨勢分析 導(dǎo)出用實(shí)體類
* @author www
*
*/
public class DeviceAddDyn implements Serializable{

/**
* 版本信息
*/
private static final long serialVersionUID = -2349692708851483212L;

/**
* 列名稱
*/
private String colName;

/**
* 添加數(shù)量
*/
private String addNum;

/**
* 總數(shù)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;
}
}

然后通過
deviceList = (List<DeviceAddDyn>) jsonArray.toCollection(jsonArray, DeviceAddDyn.class);
這個(gè)方法就將一段JSONArray轉(zhuǎn)化為list集合,對象為DeviceAddDyn
