利用JSONObject将json 字符串转换为java bean对象

利用JSONObject将下面这个json字符串转换为javabean对象

 {
    "assetInfoList":[{
        "devsno":"xxx",
        "assetno":"xxx",
        "domain":"xxx",
        "devtype":"xxx",
        "category":"xxx",
        "vendor":"xxx",
        "hardver":"xxx",
        "softwarever":"xxx",
        "custname":"xxx",
        "custaddr":"xxx！",
        "contactinfo":"xxx",
        "orders":"xxx,xxx",
        "services":"xxx,xxx,xxx",
        "opertime":"xxx",
        "orderNumber":"xxx",
        "taskNumber":"xxx",
        "multicast":"xxx"}],
    "infname":"xxx",
    "requestserial":"xxx",
    "sysname":"xxx"
}

解析过程分析：

private AMSRequestStruct decode(String jsonStr) {
    //实体对象
    AMSRequestStruct request = new AMSRequestStruct();
    //将jsonStr转为JSON对象
    JSONObject obj = JSONObject.fromObject(jsonStr);
    //获取json对象的值    json格式为key-value形式
    request.setSysname(obj.getString("sysname").trim());
    request.setRequestserial(obj.getString("requestserial").trim());
    request.setInfname(obj.getString("infname").trim());
    
    //json数组转换为JSONArray
    JSONArray array = obj.getJSONArray("assetInfoList");
    //声明一个list
    ArrayList list = new ArrayList();
    //循环遍历json数组
    for (int i = 0; i < array.size(); i++) {
    JSONObject asset = array.getJSONObject(i);
    AssetInfo info = new AssetInfo();
    info.setDevsno(asset.getString("devsno").trim());
    info.setAssetno(asset.getString("assetno").trim());
    info.setCmsdomain(asset.getString("domain").trim());
    info.setDomain(asset.getString("domain").trim());
    info.setDevtype(asset.getString("devtype").trim());
    info.setCategory(asset.getString("category").trim());
    info.setVendor(asset.getString("vendor").trim());
    info.setHardver(asset.getString("hardver").trim());
    info.setSoftwarever(asset.getString("softwarever").trim());
    info.setCustname(asset.getString("custname").trim());
    info.setCustaddr(asset.getString("custaddr").trim());
    info.setContactinfo(asset.getString("contactinfo").trim());
    info.setOrders(asset.getString("orders").trim());
    info.setServices(asset.getString("services").trim());
    info.setMulticast(asset.getString("multicast").trim());
    info.setOpertime(asset.getString("opertime").trim());
    info.setStatus(request.getInfname2(request.getInfname()));
    info.setDevstatus(request.getFlag2(request.getInfname2(request.getInfname())));
    info.setInvtype(request.getFlag3(request.getInfname2(request.getInfname())));
    info.setOrdernumber(asset.getString("orderNumber"));
    info.setTasknumber(asset.getString("taskNumber"));
    //将info添加到list中
    list.add(info);
    }
    request.setAssetInfoList(list);
    return request;
    }
