利用JSONObject將json 字符串轉換為java bean對象

利用JSONObject將下面這個json字符串轉換為javabean對象

 {
	"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"
}

解析過程分析：

private AMSRequestStruct decode(String jsonStr) {
    //實體對象
	AMSRequestStruct request = new AMSRequestStruct();
    //將jsonStr轉為JSON對象
	JSONObject obj = JSONObject.fromObject(jsonStr);
    //獲取json對象的值    json格式為key-value形式
	request.setSysname(obj.getString("sysname").trim());
	request.setRequestserial(obj.getString("requestserial").trim());
	request.setInfname(obj.getString("infname").trim());
    
    //json數組轉換為JSONArray
	JSONArray array = obj.getJSONArray("assetInfoList");
    //聲明一個list
	ArrayList list = new ArrayList();
    //循環遍歷json數組
	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"));
	//將info添加到list中
	list.add(info);
	}
	request.setAssetInfoList(list);
	return request;
	}
