Gson解析后的数据存到本地数据库 耗时的问题

最近一直在做数据同步 从接口那边拿到的数据存在本地数据库的过程中 加载数据的时间一直是个很头疼的问题 下面有两种方法 对比一下 第二种加载数据耗时更少 更为快捷一些

// [start] 字典数据同步
public static void getUpdateDictionary(final String clientVersion, final Context context) {
// TODO Auto-generated method stub
DicComplete=false;
HashMap<String, String> paramDictionary = new HashMap<String, String>();
paramDictionary.put("clientVersion", clientVersion);
System.out.println("=======getUpdateDictionary" + clientVersion);
BaseProtocol updateProtocol = new BaseProtocol(paramDictionary);
final String jsonDictionary = updateProtocol.toJson();

paramsDictionary = new RequestParams();
paramsDictionary.addQueryStringParameter("detail", jsonDictionary + "&" + DesityUtil.Random());

NetUtils.getData(HttpMethod.POST, ConstantValue.COMMON + ConstantValue.UPDATEDICTIONARY_URL, paramsDictionary, new RequestCallBack<String>() {
@Override
public void onSuccess(ResponseInfo<String> responseInfo) {
Gson gsonDictionary = new Gson();
if (HispitalProtocol.checkResult(responseInfo)) {
System.out.println("=======responseInfo" + responseInfo);
final List<SysDicVO> fromJsonDictionary = gsonDictionary.fromJson(HispitalProtocol.getContentObj(responseInfo).toString(),
new TypeToken<List<SysDicVO>>() {}.getType());
new Thread() {
public void run() {
try {
Date curDate = new Date(System.currentTimeMillis());

db = DBManager.getInstance(new DBHelper(context)).openDatabase();
db.beginTransaction();
daoDictionary = new SysDicDaoImpl(db);

int row = 0;
for (int i = 0; i < fromJsonDictionary.size(); i++) {
SysDicVO sysDicVO = new SysDicVO();
sysDicVO.setId(fromJsonDictionary.get(i).getId());
sysDicVO.setCode(fromJsonDictionary.get(i).getCode());
sysDicVO.setName(fromJsonDictionary.get(i).getName());
sysDicVO.setParent_id(fromJsonDictionary.get(i).getParent_id());
sysDicVO.setBase_version(fromJsonDictionary.get(i).getBase_version());
sysDicVO.setStatus(fromJsonDictionary.get(i).getStatus());
// sysDicVO.setSort(0);

List<SysDicVO> sysDicVOs = daoDictionary.findByCondition(new String[] { DBHelper.T_ID },
DBHelper.T_ID + " = ? ", new String[] { sysDicVO.getId() }, null);
if (null != sysDicVOs && sysDicVOs.size() > 0) {
daoDictionary.update(sysDicVO, sysDicVO.getId());
} else {
daoDictionary.insert(sysDicVO);
}

// row = daoDictionary.update(sysDicVO, sysDicVO.getId());
// if (row==0){
// daoDictionary.insert(sysDicVO);
// }
}
db.setTransactionSuccessful();

Date endDate = new Date(System.currentTimeMillis());
long diff = endDate.getTime() - curDate.getTime();

Toast.makeText(context, "=================diff================ " + diff, 1000);

DicComplete=true;
} catch (Exception e) {
DicComplete=false;
e.printStackTrace();
} finally {
if (null != db)
db.endTransaction();
}
}
}.start();
}
}

@Override

});
}

Oracle如何通过dataLink复制远程数据库的CLOB\BLOB字段数据到本地数据库

Oracle不支持直接通过Database Link复制远程数据库表的CLOB/BLOB字段数据到本地数据库. 像如下的SQL是不能执行的.(ipop_topic表有一个CLOB的字段) insert into ipop_topicselect * from [email protected] where application_id=1000 但是,我们可以借助全局临时表,先把数据复制到临时表,再从临时表转移到你的目的表. create global temporary table ipop_

关于listview中图片切圆,网络请求数据,并Gson解析后得到list

碰到json数据.里面格式众多.list+string[]+等等.具体json参数如下: eg:以下为接口参数: "responseData":{ "brandCode": "10000002", "brandName": "健康卡", "channelId": 20001, "channelIdOldPc": "wap-fmall-yztapp"

用GSON解析Json格式数据

GSON是谷歌提供的开源库,用来解析Json格式的数据,非常好用.如果要使用GSON的话,则要先下载gson-2.2.4.jar这个文件,如果是在Android项目中使用,则在Android项目的libs目录下添加这个文件即可:如果是在Java项目中,则把gson-2.2.4.jar先添加到当前项目的任意一个包中,然后右键点击这个jar包 -> 构建路径 -> 添加至构建路径.这样准备工作就做好了. (一)单条无嵌套Json数据的解析 比如有如下Json数据:{"name"

Python爬虫入门 | 6 将爬回来的数据存到本地

1.用Python语句存储数据 写文件时,我们主要用到 with open() 语句: with open(name,mode,encoding) as file:   file.write()   # 注意,with open() 后面的语句有一个缩进 name:包含文件名称的字符串,比如:'xiaozhu.txt'; mode:决定了打开文件的模式,只读/写入/追加等; encoding:表示我们要写入数据的编码,一般为 utf-8 或者 gbk ; file:表示我们在代码中对文件的命名.
