How can I somehow "store" a json file in a Spring-Boot program so my web app then reads this json

Basically, I'm writing my first Spring-Boot program, and I have to get a list of products stored on a JSON file to display each product using VueJS (I know how to use Vue, I just need to get the JSON data somewhere in the webpage or smth)
I spent last 3'5 hours looking at tutorials about consuming JSON's and POST stuff and none helped.

Lets call your file config.json.
In a typical maven project, keep your file at
src/main/resources/config.json
In your code, read it like
try {
ClassPathResource configFile = new ClassPathResource("config.json");
String json = IOUtils.toString(configFile.getInputStream(), Charset.forName(Util.UTF_8));
} catch (IOException e) {
String errMsg = "unexpected error while reading config file";
logger.error(errMsg, e);
throw new Exception(e);
}
After this, use Jackson or GSON to read the json into an object. From there you can either reference it directly as a static attribute or as an attribute in component as per your use case.

Hope this code will work for you
public class JsonReader{
public static void readFromJson() throws Exception {
InputStream inStream = JsonReader.class.getResourceAsStream("/" + "your_config_file.json");
Map<String, String> keyValueMap =
new ObjectMapper().readValue(inStream, new TypeReference<Map<String, String>>() {});
inStream.close();
}
}
You might need to add the maven dependency for ObjectMapper()

scriptella executor with xml as string instead of file

I am trying to use scriptella in my project to copy data from one db to another, now the application has a frontend which users can use to create mapping between tables and create dynamic queries, now currently once the user submits the frontend queries are passed via a query engine and a scriptella xml is created using freemarker template
however to execute the xml the executor expects a file instead of a xml string currently i am achieving this by creating a xml in temp directory and deleting it post execution of query, is there any way i can skip file creation and execute the query as a xml string

You can create a custom URLStreamHandler that will serve streams directly from memory. This is similar to what was done in AbstractTestCase. It can be registered by calling URL.setURLStreamHandlerFactory. See Registering and using a custom java.net.URL protocol or Is it possible to create an URL pointing to an in-memory object?
After that, use
EtlExecutor.newExecutor(java.net.URL) with the new URI, e.g. new URL("memory://file")

I had a similar use case. I downloaded the code and made a small change in the core. Due to some private functions I had no choice.
in
package scriptella.configuration.ConfigurationFactory
I added the following function:
public ConfigurationEl createConfigurationFromTxt(String xml, final ParametersCallback externalParameters ) {
try {
DocumentBuilder db = DBF.newDocumentBuilder();
db.setEntityResolver(ETL_ENTITY_RESOLVER);
db.setErrorHandler(ETL_ERROR_HANDLER);
final InputStream in = new ByteArrayInputStream(xml.getBytes());
final Document document = db.parse(in);
HierarchicalParametersCallback params = new HierarchicalParametersCallback(
externalParameters == null ? NullParametersCallback.INSTANCE : externalParameters, null);
PropertiesSubstitutor ps = new PropertiesSubstitutor(params);
return new ConfigurationEl(new XmlElement(
document.getDocumentElement(), resourceURL, ps), params);
} catch (IOException e) {
throw new ConfigurationException("Unable to load document: " + e, e);
} catch (Exception e) {
throw new ConfigurationException("Unable to parse document: " + e, e);
}
}
Then from my code I can do something like this:
ConfigurationFactory cf = new ConfigurationFactory();
ConfigurationEl conf = cf.createConfigurationFromTxt(FETCH_ETLS, p);
EtlExecutor exec = new EtlExecutor(conf);

How to use appProperties in Google Drive api v3?

How to set the app properties of a file using Google Drive v3 in java?
The reference says: "files.update with {'appProperties':{'key':'value'}}", but I don't understand how to apply that to my java code.
I've tried things like
file = service.files().create(body).setFields("id").execute();
Map<String, String> properties = new HashMap<>();
properties.put(DEVICE_ID_KEY, deviceId);
file.setAppProperties(properties);
service.files().update(file.getId(), file).setFields("appProperties").execute();
but then I get an error that "The resource body includes fields which are not directly writable."
And to get the data:
File fileProperty = service.files().get(sFileId).setFields("appProperties").execute();
So how to set and get the properties for the file?
Thanks! :)
Edit
I tried
file = service.files().create(body).setFields("id").execute();
Map<String, String> properties = new HashMap<>();
properties.put(DEVICE_ID_KEY, deviceId);
file.setAppProperties(properties);
service.files().update(file.getId(), file).execute();
but I still get the same error message.

To avoid this error on v3
"The resource body includes fields which are not directly writable."
when calling update, you need to create an empty File with the new changes and pass that to the update function.
I wrote this and other notes as a v3 Migration Guide here.

The Drive API client for Java v3 indicates that the File.setAppProperties will require a Hashmap<String,String> parameter. Try to remove the setFields("appProperties") call since you are trying to overwrite appProperties itself (you're still calling Update at this time).
When retrieving appProperties, you'll just need to call getAppProperties.
Hope this helps!

File fileMetadata = new File();
java.io.File filePath = new java.io.File(YOUR_LOCAL_FILE_PATH);
Map<String, String> map = new HashMap<String, String>();
map.put(YOUR_KEY, YOUR_VALUE); //can be filled with custom String
fileMetadata.setAppProperties(map);
FileContent mediaContent = new FileContent(YOUR_IMPORT_FORMAT, filePath);
File file = service.files().create(fileMetadata, mediaContent)
.setFields("id, appProperties").
.execute();
YOUR_IMPORT_FORMAT, fill this with the value in this link, https://developers.google.com/drive/api/v3/manage-uploads, there is explanation below the example code
setFields("id, appProperties"), fill this with the value in this link: https://developers.google.com/drive/api/v3/migration, this the most important part I think, if you don't set the value in the setFields method your additional input will not be written

With version v3, to add or update appProperties for an existing file and without this error:
"The resource body includes fields which are not directly writable."
You should do:
String fileId = "Your file id key here";
Map<String, String> appPropertiesMap = new HashMap<String, String>();
appPropertiesMap.put("MyKey", "MyValue");
appPropertiesMap.put("MySecondKey", "any value");
//set only the metadata you want to change
//do not set "id" !!! You will have "The resource body includes fields which are not directly writable." error
File fileMetadata = new File();
fileMetadata.setAppProperties(appPropertiesMap);
File updatedFileMetadata = driveService.files().update(fileId, fileMetadata).setFields("id, appProperties").execute();
System.out.printf("Hey, I see my appProperties :-) %s \n", updatedFileMetadata.toPrettyString());

Insert variables into SAS using JAVA (IOM Bridge). Should i use CORBA stubs and JDBC or is there any other alternative?

This is part of my code snippet
WorkspaceConnector connector = null;
WorkspaceFactory workspaceFactory = null;
String variableListString = null;
Properties sasServerProperties = new Properties();
sasServerProperties.put("host", host);
sasServerProperties.put("port", port);
sasServerProperties.put("userName", userName);
sasServerProperties.put("password", password);
Properties[] sasServerPropertiesList = { sasServerProperties };
workspaceFactory = new WorkspaceFactory(sasServerPropertiesList, null, logWriter);
connector = workspaceFactory.getWorkspaceConnector(0L);
IWorkspace sasWorkspace = connector.getWorkspace();
ILanguageService sasLanguage = sasWorkspace.LanguageService();
//send variable list string
//continued
I need to send the "variableListString" to the SAS server through IOM bridge. Java SAS API doesn't give explicit ways to do it. Using CORBA and JDBC is the best way to do it?? Give me a hint how to do it. Is there any alternative method to do it??

This was asked a while back but useful in case anyone is still looking to do the same.
One way to do this is build a string of sas code and submit it to the server. We use this method for setting up variables on the host for the connected session. You can also use this technique to include sas code using code like %include "path to my code/my sas code.sas";:
...continue from code in the question...
langService = iWorkspace.LanguageService();
StringBuilder sb = new StringBuilder();
sb.append("%let mysasvar=" + javalocalvar);
... more variables
try {
langService.Submit(sb.toString());
} catch (GenericError e) {
e.printStackTrace();
}

Setting/Updating multiple document properties in SharePoint 2010 using OpenCMIS

Have tried to search for this almost 'everywhere', but couldn't find a pointer as to how to implement this. Please kindly review my code and offer suggestions on how to set/update ALL documents properties in SharePoint using OpenCMIS. Have created the documents successfully using CMIS, however I'm not able to populate different values for different documents.
For example, a.pdf, b.pdf have different properties. So when I update them, i expect the value to be mapped from array of values assigned to them but at the moment, the same value are being append to all the documents...
Please see my code below, hopefully it will make things clearer:
try {
String [] nextLine =null;
CSVReader reader = new CSVReader(new FileReader(indexFileLocation));
List content = reader.readAll();
for (Object o : content) {
nextLine = (String[]) o;
System.out.println("\n"+ nextLine[2] + "\n"+nextLine[7] + "\n"+ nextLine[6]);
}
//reader.close();
Map <String, Object> newDocProps = new HashMap<String, Object>();
newDocProps.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document");
newDocProps.put(PropertyIds.NAME, ff.getName());
Document doc = newFolder.createDocument(newDocProps, contentStream, VersioningState.NONE);
CmisObject cmisobject = (Document) session.getObject(doc.getId());
Map<String, Object> pp = new HashMap<String, Object>();
//pp.put(PropertyIds.OBJECT_ID, "Name");
pp.put("WorkflowNumber", nextLine[7]);
pp.put("InvoiceDate", nextLine[2]);
cmisobject.updateProperties(pp);
Any help is appreciated.
