Azure functions using Java - How to created #BlobTrigger - java

i need to created Azure function BlobTrigger using Java to monitor my storage container for new and updated blobs.
tried with below code
import java.util.*;
import com.microsoft.azure.serverless.functions.annotation.*;
import com.microsoft.azure.serverless.functions.*;
import java.nio.file.*;
import java.io.*;
import java.net.URL;
import java.net.URLConnection;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import com.microsoft.azure.storage.*;
import com.microsoft.azure.storage.blob.*;
#FunctionName("testblobtrigger")
public String testblobtrigger(#BlobTrigger(name = "test", path = "testcontainer/{name}") String content) {
try {
return String.format("Blob content : %s!", content);
} catch (Exception e) {
// Output the stack trace.
e.printStackTrace();
return "Access Error!";
}
}
when executed it is showing error
Storage binding (blob/queue/table) must have non-empty connection. Invalid storage binding found on method:
it is working when added connection string
public String kafkablobtrigger(#BlobTrigger(name = "test", path = "testjavablobstorage/{name}",connection=storageConnectionString) String content) {
why i need to add connection string when using blobtrigger?
in C# it is working without connection string:
public static void ProcessBlobContainer1([BlobTrigger("container1/{blobName}")] CloudBlockBlob blob, string blobName)
{
ProcessBlob("container1", blobName, blob);
}
i didn't see any Java sample for Azure functions for #BlobTrigger.

After all, connection is necessary for the trigger to identify where the container locates.
After test I find #Mikhail is right.
For C#, the default value(in local.settings.json or in application settings in portal) will be used if connection is ignored. But unfortunately there's no same settings for java.
You can add #StorageAccount("YourStorageConnection") below your #FuncionName as it's another valid way to choose. And value of YourStorageConnection in local.settings.json or in portal's application settings is up to you.
You can follow this tutorial, use mvn azure-functions:add to find four(Http/Blob/Queue/TimerTrigger) templates for java.

How to create a file from an action event for an IntelliJ plugin?

I'm creating a PhpStorm plugin with IntelliJ IDEA Community Edition and I would like to know how to create a file on disk from a PSIFile or VirtualFile.
Here my code: (The context is an action from NewGroup)
I've tried to use the PsiDirectory.copyFileFrom method to create the file but I have an exception com.intellij.util.IncorrectOperationException: Cannot copy non-physical file: PHP file
package fr.florent.idea.zendgenerator.action.NewGroup;
import com.intellij.openapi.actionSystem.AnActionEvent;
import com.intellij.openapi.actionSystem.LangDataKeys;
import com.intellij.openapi.fileEditor.impl.LoadTextUtil;
import com.intellij.openapi.vfs.VfsUtil;
import com.intellij.openapi.vfs.VirtualFile;
import com.intellij.psi.PsiDirectory;
import com.intellij.psi.PsiFile;
import com.intellij.psi.PsiFileFactory;
import com.intellij.util.ResourceUtil;
import com.jetbrains.php.lang.PhpFileType;
import fr.florent.idea.zendgenerator.action.AbstractDumbAwareAction;
import icons.PhpIcons;
import org.jetbrains.annotations.NotNull;
import java.net.URL;
public class CreateQueryAction extends AbstractDumbAwareAction {
public CreateQueryAction() {
super("Query", "Create query", PhpIcons.Php_icon);
}
#Override
public void actionPerformed(#NotNull AnActionEvent e) {
URL url = ResourceUtil.getResource(getClass(), "templates", "query.php"); // it contains an empty PHP class
VirtualFile virtualFile = VfsUtil.findFileByURL(url);
PsiFile file = PsiFileFactory.getInstance(e.getProject()).createFileFromText(
virtualFile.getPath(),
PhpFileType.INSTANCE,
LoadTextUtil.loadText(virtualFile)
);
PsiDirectory directory = LangDataKeys.IDE_VIEW.getData(e.getDataContext()).getOrChooseDirectory();
directory.copyFileFrom("query.php", file);
System.out.println("Create query");
}
}
I would like to have the file created in the project folder from the context of my action.
It will be great if someone can explain the process of creating a file in a IntelliJ plugin. I think the docs is really light.
In my case I would like to have the process to edit the query.php file, rename the class name, add method, properties, doc block and save it to the disk but I don't understand the PSI element.
You might want to ask this also on JB forum, there's a similar question: https://intellij-support.jetbrains.com/hc/en-us/community/posts/360001787320-Create-VirtualFile-or-PsiFile-from-content
The answer is:
final PsiFileFactory factory = PsiFileFactory.getInstance(project);
final PsiFile file = factory.createFileFromText(language, text);

How to integrate karate with testrail

I am new to Java and using karate for API automation. I need help to integrate testrail with karate. I want to use tags for each scenario which will be the test case id (from testrail) and I want to push the result 'after the scenario'.
Can someone guide me on this? Code snippets would be more appreciated. Thank you!
I spent a lot of effort for this.
That's how I implement. Maybe you can follow it.
First of all, you should download the APIClient.java and APIException.java files from the link below.
TestrailApi in github
Then you need to add these files to the following path in your project.
For example: YourProjectFolder/src/main/java/testrails/
In your karate-config.js file, after each test, you can send your case tags, test results and error messages to the BaseTest.java file, which I will talk about shortly.
karate-config.js file
function fn() {
var config = {
baseUrl: 'http://111.111.1.111:11111',
};
karate.configure('afterScenario', () => {
try{
const BaseTestClass = Java.type('features.BaseTest');
BaseTestClass.sendScenarioResults(karate.scenario.failed,
karate.scenario.tags, karate.info.errorMessage);
}catch(error) {
console.log(error)
}
});
return config;
}
Please dont forget give tag to scenario in Feature file.
For example #1111
Feature: ExampleFeature
Background:
* def conf = call read('../karate-config.js')
* url conf.baseUrl
#1111
Scenario: Example
Next, create a runner file named BaseTests.java
BaseTest.java file
package features;
import com.intuit.karate.junit5.Karate;
import net.minidev.json.JSONObject;
import org.junit.jupiter.api.BeforeAll;
import testrails.APIClient;
import testrails.APIException;
import java.io.IOException;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.HashMap;
import java.util.List;
import java.util.Locale;
import java.util.Map;
public class BaseTest {
private static APIClient client = null;
private static String runID = null;
#BeforeAll
public static void beforeClass() throws Exception {
String fileName = System.getProperty("karate.options");
//Login to API
client = new APIClient("Write Your host, for example
https://yourcompanyname.testrail.io/");
client.setUser("user.name#companyname.com");
client.setPassword("password");
//Create Test Run
Map data = new HashMap();
data.put("suite_id", "Write Your Project SuitId(Only number)");
data.put("name", "Api Test Run");
data.put("description", "Karate Architect Regression Running");
JSONObject c = (JSONObject) client.sendPost("add_run/" +
TESTRAİL_PROJECT_ID, data);
runID = c.getAsString("id");
}
//Send Scenario Result to Testrail
public static void sendScenarioResults(boolean failed, List<String> tags, String errorMessage) {
try {
Map data = new HashMap();
data.put("status_id", failed ? 5 : 1);
data.put("comment", errorMessage);
client.sendPost("add_result_for_case/" + runID + "/" + tags.get(0),
data);
} catch (IOException e) {
e.printStackTrace();
} catch (APIException e) {
e.printStackTrace();
}
}
#Karate.Test
Karate ExampleFeatureRun() {
return Karate.run("ExampleFeatureRun").relativeTo(getClass());
}
}
Please look at 'hooks' documented here: https://github.com/intuit/karate#hooks
And there is an example with code over here: https://github.com/intuit/karate/blob/master/karate-demo/src/test/java/demo/hooks/hooks.feature
I'm sorry I can't help you with how to push data to testrail, but it may be as simple as an HTTP request. And guess what Karate is famous for :)
Note that values of tags can be accessed within a test, here is the doc for karate.tagValues (with link to example): https://github.com/intuit/karate#the-karate-object
Note that you need to be on the 0.7.0 version, right now 0.7.0.RC8 is available.

Best way to connect java swing app to ms access db on a shareserver?

Currently im developing a java swing application that I'd like to serve as the GUI for CRUD operations on a MS access database. Currently, everyone on the team that will be using this application updates a spreadsheet on a shareserver. They'd like to switch over to a UI that better suits their purposes, and transition the spreadsheet to a database.
I'm planning on putting an executable jar and the ms access database file on the shareserver. This is where the jar will be accessed.
I don't want users to have to be messing with ODBC settings. Is there a library that can help with this?
UPDATE: Shailendrasingh Patil's suggestion below worked best for me. This took me a little bit of research and the setup was a bit confusing. But I eventually got everything working the way I was hoping. I used Gradle to pull in the necessary dependencies to use UcanAccess.
The following is a snippet from my DatabaseController class:
import javax.swing.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
public class DatabaseController {
public DatabaseController() {}
public void addOperation(String date, String email, String subject, String body) {
try{
Connection con = DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\user\\Desktop\\TestDatabase.accdb;jackcessOpener=CryptCodecOpener","user", "password");
String sql = "INSERT INTO Email (Date_Received, Email_Address, Subject, Message) Values " +
"('"+date+"'," +
"'"+email+"'," +
"'"+subject+"'," +
"'"+body+"')";
Statement statement = con.createStatement();
statement.execute(sql);
}
catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage(),"Error",
JOptionPane.ERROR_MESSAGE);
e.printStackTrace();
}
}
}
The following class is also required:
import java.io.File;
import java.io.IOException;
import com.healthmarketscience.jackcess.CryptCodecProvider;
import com.healthmarketscience.jackcess.Database;
import com.healthmarketscience.jackcess.DatabaseBuilder;
import net.ucanaccess.jdbc.JackcessOpenerInterface;
public class CryptCodecOpener implements JackcessOpenerInterface {
public Database open(File fl,String pwd) throws IOException {
DatabaseBuilder dbd =new DatabaseBuilder(fl);
dbd.setAutoSync(false);
dbd.setCodecProvider(new CryptCodecProvider(pwd));
dbd.setReadOnly(false);
return dbd.open();
}
}
I apologize for the bad indentations.
You should use UCanAccess drivers to connect to MS-Access. It is a pure JDBC based and you don't need ODBC drivers.

How to get this property value in my java code?

I'm learning Java and sometimes I have some problem to retrieve the information I need from objects...
When I debug my code I can see in targetFile, a path property but I don't know how to get it in my code.
This is a screenshot:
(source: toile-libre.org)
This is my complete code:
package com.example.helloworld;
import com.github.axet.wget.WGet;
import com.github.axet.wget.info.DownloadInfo;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.File;
import java.io.IOException;
import java.net.URL;
public class HelloWorld {
public static void main(String[] args) throws IOException {
nodejs();
}
public static void nodejs() throws IOException {
// Scrap the download url.
Document doc = Jsoup.connect("http://nodejs.org/download").get();
Element link = doc.select("div.interior:nth-child(2) > table:nth-child(2) > tbody:nth-child(1) > tr:nth-child(1) > td:nth-child(3) > a:nth-child(1)").first();
String url = link.attr("abs:href");
// Print the download url.
System.out.println(url);
// Download file via the scraped url.
URL download = new URL(url);
File target = new File("/home/lan/Desktop/");
WGet w = new WGet(download, target);
w.download();
// Get the targetFile property
// ???
}
}
How can I get this value?
I do not know your code but the field you are interested in may be encapsulated and thus not accessible in your code, but the debugger can see it at runtime :)
Update:
https://github.com/axet/wget/blob/master/src/main/java/com/github/axet/wget/WGet.java
The field is default package, you can only access it from within the package.
This can be frustrating at times, but you should ask yourself why the designers of this class decided to hide this field.
