I am trying to map .vcf to my DTO (Simple POJO) , here is what i have tried :
Code:
List<VCard> list = Ezvcard.parse(fr).all(); // fr is FileReader
SomeDto someDto = new SomeDto ();
List<SomeDto > someDtoList = new ArrayList<>();
for (Iterator<VCard> iterator = list.iterator(); iterator.hasNext();) {
VCard vCard = iterator.next();
c.setFirstName(vCard.getFormattedName().getValue());
c.setEmailAddress(vCard.getEmails().get(0).getValue());
c.setMobilePhone(vCard.getTelephoneNumbers().get(0).getText());
someDtoList .add(c);
}
return someDtoList ;
Is there a simplified way of handling this? Like in-built methods to take care if DTO has more properties, so we can avoid manual work?
I am using vCard JAR: https://github.com/mangstadt/ez-vcard
Maybe try this out https://github.com/mangstadt/ez-vcard it was originally a development by google and offers a lot of possibilities.
U may try to convert your vcards to json, to have more possibilities for further work.
String json = Ezvcard.writeJson(vcard).go();

I have the following SP (SQL server) that return a Json output.
BEGIN
SET #jsonOutput = (
SELECT
Program.Name AS ProgramName,
ProgramOwner.FirstName AS OwnerFirstName,
FROM ProgramOwner, Program
WHERE Program.Id = ProgramOwner.ProgramOwner2Program
FOR JSON PATH,WITHOUT_ARRAY_WRAPPER)
I would like to map the return Json output to a List of ProgramDto via modelMapper. Not sure hot to do that since the return values from call.execute is an Object.
Something like this:
SimpleJdbcCall call = new
SimpleJdbcCall(jdbcTemplate).withProcedureName(programProc).declareParameters(
new SqlOutParameter("jsonOutput", Types.VARCHAR));
Map<String,Object>out = call.execute(new MapSqlParameterSource());
if(out.size()>0) {
// Only to show what I am trying to do
Type rootType = new TypeToken<List<ProgramDto>>() {}.getType();
modelMapper.map(out.get("jsonOutput"),rootType );
}
Thank you
As I understood you are trying to get a list of object from
You can use Jackson api
Like this
say for example your json is in variable named jsonData, then you can get the object you need like below.
ObjectMapper mapper = new ObjectMapper();
List<Type> myList = Arrays.asList(mapper.readValue(jsonData, Type[].class));

I am new to shapefile processing. Kindly guide me on how to achieve my below query.
I am using this shapefile tl_2018_us_aiannh.shp from census.gov : TIGER-LINE. I am to obtain the census block group entities like Block, Tract, County subdivision and County details from the shapefile based on the latitude and longitude provided by the user.
My requirement is to achieve this by shapefile alone and not through any API's.
Can someone help on which framework I can achieve this?
What I've tried/using so far:
I have used GeoTools to read the shapefile . Can I continue using the same? Will my requirement be achievable by this tool?
I have gone through a documentation from census.gov which states:
The Census Bureau assigns a code and these appear in fields such as
“TRACTCE”, where “CE” stands for Census. Finally, state-submitted
codes end in “ST”, such as “SLDLST”, and local education agency codes
end in “LEA”, as in “ELSDLEA”.
Which I tried in my code by:
File file = new File("D:\\tl_2018_us_aiannh.shp");
try {
Map<String, String> connect = new HashMap();
connect.put("url", file.toURI().toString());
DataStore dataStore = DataStoreFinder.getDataStore(connect);
String[] typeNames = dataStore.getTypeNames();
String typeName = typeNames[0];
System.out.println("Reading content " + typeName);
SimpleFeatureSource featureSource = dataStore
.getFeatureSource(typeName);
SimpleFeatureCollection collection = featureSource.getFeatures();
SimpleFeatureIterator iterator = collection.features();
try {
while (iterator.hasNext()) {
SimpleFeature feature = iterator.next();
GeometryAttribute sourceGeometry = feature
.getDefaultGeometryProperty();
String name = (String) (feature).getAttribute("TRACTCE");
Property property = feature.getProperty("TRACTCE");
System.out.println(property);
}
} finally {
iterator.close();
}
} catch (Throwable e) {
e.getMessage();
}
But I am receiving null as the value.
Any help would be much helpful.
I have found the solution to this. Hope this would be helpful to someone in need.
SimpleFeature is the type that has the attributes of shape files that you can check when you try to debug or print a line on runtime. You can use the SimpleFeature to get the property. The attributes can be achieved by:
try {
while (iterator.hasNext()) {
SimpleFeature feature = iterator.next();
Property intptlat = feature.getProperty("TRACTCE");
}
}
Make sure you are choosing the Block Groups as the layer type for download in Tiger-Line or which ever site is concerned, where you download the shape file.
In my Android app, I used Gson in order to save/load the object's Arraylist in SharedPreferences. Follows are my code using Gson.
public static ArrayList<RequestModal> getModalList(Context ctx) {
Gson gson = new Gson();
String json = getSharedPreferences(ctx).getString("ModalList", new Gson().toJson(new ArrayList<>()));
Type type = new TypeToken<ArrayList<RequestModal>>() {}.getType();
return gson.fromJson(json, type);
}
In here "RequestModal" is the simple object include a bit of strings and integers.
It works well in case "online". But if internet is offline, forever works on below code.
Type type = new TypeToken<ArrayList<RequestModal>>() {}.getType();
How can I solve it? What is the way implement the feature like this with/without using Gson? Please help me anyone having a good idea.
Thank you in advance.
You can implement this without Gson:
public static EpisodeDetails parseEpisodeDetails(String content) {
EpisodeDetails episodeDetails = new EpisodeDetails();
try {
JSONObject jsonObject = new JSONObject(content);
episodeDetails.title = jsonObject.getString("title");
episodeDetails.subTitle = jsonObject.getString("subtitle");
episodeDetails.synopsis = jsonObject.getString("synopsis");
episodeDetails.ends_on = jsonObject.getString("ends_on");
JSONArray images = jsonObject.getJSONArray("image_urls");
if (images.length() > 0) {
episodeDetails.image_url = images.getString(0);
}
} catch (JSONException e) {
e.printStackTrace();
return null;
}
return episodeDetails;
}
What I'm doing is just taking the String, in your case the one saved on the shared prefs called ModalList and inserting the values on my structure, on my code the structure is called EpisodeDetails, on your code the correspondent is RequestModal. If you don't want to do it via code and want to try another library I recommend Jackson.
Another thing, on this line:
String json = getSharedPreferences(ctx).getString("ModalList", new Gson().toJson(new ArrayList<>()));
Your second parameter is not necessary. getString takes the key to load as first parameter and a default value as second paramter (in the case of empty result). You could change this to "" or null.
Well, another solution to your problem could be TinyDB. It makes use of Gson to save ArrayLists of objects in sharedPrefs, its usage is so simple as:
Person person = new Person("john", 24);
tinydb.putObject("user1", person);
ArrayList<Person> usersWhoWon = new ArrayList<Person>();
tinydb.putListObject("allWinners", usersWhoWon);
and that's it, check out my link given above to see the usage details.
Is there any way to Iterate all described services in routes file? URL and HTTP methods are needed.
I need this feature for running some integration test.
I am using Play for Java.
Not easily. I managed to hack my way through it a while ago(no scala know-how). I'll post that code maybe it can be of use.
public static List<String[]> parseRoutes() {
scala.Option<play.core.Router.Routes> option = Play.application().getWrappedApplication().routes();
if (option.isDefined()) {
play.core.Router.Routes routes = option.get();
scala.collection.Seq<scala.Tuple3<String, String, String>> doc = routes.documentation();
scala.collection.Iterator<scala.Tuple3<String, String, String>> it = doc.iterator();
List<String[]> listOfRoutes = new ArrayList<String[]>();
while(it.hasNext()) {
scala.Tuple3<String, String, String> tuple = it.next();
//tuple._1() is the method and tuple._2() the url... tuple._3() is the controller name
String[] route = {tuple._1(), tuple._2()};
listOfRoutes.add(route);
Logger.debug("route -> " + Arrays.toString(route));
}
return listOfRoutes;
}
return null;
}
Don't worry about the .iterator() showing a The method iterator() is ambiguous for the type Seq<Tuple3<String,String,String>>. It compiles just fine in play.
If I want to read the data from oracle table using hashmap then i can read it like this.........
String sql = "select * from DPY_VW_REP_DELIVERY_DTLS where weighed_date between ? and ?";
Object[] queryParams = new Object[] {dateFrom, dateTo};
List rsList = this.getJdbcTemplate().queryForList(sql, queryParams);
Iterator it = rsList.iterator();
while(it.hasNext())
{
try
{
LinkedHashMap map = (LinkedHashMap) it.next();
String[] strData = new String[14];
strData[0] = map.get("WEIGHED_DATE_AS_CHAR").toString();
strData[1] = map.get("WEIGHED_DAY_SLNO").toString();
strData[2] = map.get("PARTY_NAME").toString();
strData[3] = map.get("PARTY_ADDRESS1").toString();
strData[4] = map.get("PARTY_ADDRESS2").toString();
strData[5] = map.get("VEHICLE_NO").toString();
}
}
but if I want to read an xls file containing same data using hashmap how can i do it....
Not sure what you mean by 'using hashmap'. JdbcTemplate.queryForList returns results mapped to a List of HashMaps.
It maybe easier to read excel files using Apache POI or similar tools. Alternatively, if using a spreadsheet as a database, you can use JDBC-ODBC bridge. Then you can execute your SQL query. Here is an example for this approach.
