APPLICATION FAILED TO START when I try to work with mongoDB and SpringBoot

I have implemented a spring boot application to retrieve file data from files and save it in separate collections. When I run the application it gives the following error. I couldn't resolve it. Can anyone help me to do this?

Parameter 2 of constructor in com.bezkoder.spring.jwt.mongodb.SpringBootSecurityJwtMongodbApplication required a bean of type 'com.bezkoder.spring.jwt.mongodb.models.LogRecordCollection' that could not be found.
In an nutshell, the exception like this is self-explanatory. It means that Spring could not find a bean to be injected into your class
In your case the class SpringBootSecurityJwtMongodbApplication has a constructor:
public SpringBootSecurityJwtMongodbApplication(LogFileRepository logfileRepo, LogRecordRepository logrecordRepo, LogRecordCollection logrecordColl) {
this.logfileRepo = logfileRepo;
this.logrecordRepo = logrecordRepo;
this.logrecordColl = logrecordColl;
}
Now, LogRecordCollection has to be a bean (annotated with #Component for example, or defined in via java configuration (#Configuration marked classes and method annotated with #Bean that creates this class). Otherwise spring won't "recognize" this class a bean.
So strictly speaking this is your issue.
Now, having said that - the code you've presented in the question looks extremely messy - you mix #SpringBootApplication which is an entry point to the application, the rest controller and what not. I really recommend you to separate all this to different files to improve the code clarity and avoid unexpected exceptions that can be tricky to fix.

add below annotations in SpringBootSecurityJwtMongodbApplication
#SpringBootApplication
#ComponentScan("com.bezkoder.spring.jwt.mongodb") //to scan packages mentioned
#EnableMongoRepositories("com.bezkoder.spring.jwt.mongodb") //to activate MongoDB repositories
public class SpringBootSecurityJwtMongodbApplication { ... }

Spring Boot Web RestTemplate Send Object as Query Param

I want to make a POST request with URL Query Params set to the values of an object.
For example
http://test/data?a=1&b=2&c=3
I want to make a post request to this URL with a class like this:
public class Data {
private Integer a;
private Integer b;
private Integer c;
}
I do NOT want to do each field manually, like this:
public void sendRequest(Data data) {
String url = UriComponentsBuilder.fromHttpUrl("http://test/")
.queryParam("a", data.getA())
.queryParam("b", data.getB())
.queryParam("c", data.getC())
.toUriString();
restTemplate.postForObject(url, body, Void.class);
}
Instead, I want to use the entire object:
public void sendRequest(Data data) {
String url = UriComponentsBuilder.fromHttpUrl("http://test/")
.queryParamsAll(data) //pseudo
.toUriString();
restTemplate.postForObject(url, body, Void.class);
}

Your requirement is like QS in js. Thx qianshui423/qs . It is implementation QS in java. It is coded by a Chinese guy. At first git clone it and use below cmd to build. You will get a jar called "qs-1.0.0.jar" in build/libs (JDK required version 8)
# cd qs directory
./gradlew build -x test
Import it, I do a simple demo as below. For your requirement, you can build class to transfer your Obj into QSObject. Besides toQString, QS can parse string to QSObject. I think it powerful.
import com.qs.core.QS;
import com.qs.core.model.QSObject;
public class Demo {
public static void main(String[] args) throws Exception{
QSObject qsobj = new QSObject();
qsobj.put("a",1);
qsobj.put("b",2);
qsobj.put("c",3);
String str = QS.toQString(qsobj);
System.out.println(str); // output is a=1&b=2&c=3
}
}

Jenkins groovy init script for sonarqube configuration

I am trying to set sonarqube settings in Jenkins system property using groovy init script but I am getting below error. Can somebody help me to resolve this?
Error
+++++
groovy.lang.GroovyRuntimeException: Could not find matching constructor for:
hudson.plugins.sonar.SonarInstallation(java.lang.String, java.lang.String,
java.lang.String, hudson.plugins.sonar.model.TriggersConfig,
java.lang.String)
at groovy.lang.MetaClassImpl.invokeConstructor(MetaClassImpl.java:1732)
at groovy.lang.MetaClassImpl.invokeConstructor(MetaClassImpl.java:1532)
This is the script that I am using
import hudson.model.*
import jenkins.model.*
import hudson.plugins.sonar.SonarGlobalConfiguration
import hudson.plugins.sonar.*
import hudson.plugins.sonar.model.TriggersConfig
import hudson.tools.*
def inst = Jenkins.getInstance()
println "--> Configuring SonarQube"
SonarGlobalConfiguration global = Hudson.instance.getDescriptorByType(SonarGlobalConfiguration.class)
def sonar_inst = new SonarInstallation(
"SonarQ",
"http://localhost:9000",
"yy", // Token
new TriggersConfig(),
""
)
// Only add ADOP Sonar if it does not exist - do not overwrite existing config
def sonar_installations = sonar_conf.getInstallations()
def sonar_inst_exists = false
sonar_installations.each {
installation = (SonarInstallation) it
if (sonar_inst.getName() == installation.getName()) {
sonar_inst_exists = true
println("Found existing installation: " + installation.getName())
}
}
if (!sonar_inst_exists) {
sonar_installations += sonar_inst
sonar_conf.setInstallations((SonarInstallation[]) sonar_installations)
sonar_conf.save()
}

You missed some parameters. SonarInstallation constructor needs 7 parameters, not 5:
#DataBoundConstructor
public SonarInstallation(String name,
String serverUrl, String serverAuthenticationToken,
String mojoVersion, String additionalProperties, TriggersConfig triggers,
String additionalAnalysisProperties) {
this.name = name;
this.serverUrl = serverUrl;
this.serverAuthenticationToken = serverAuthenticationToken;
this.additionalAnalysisProperties = additionalAnalysisProperties;
this.mojoVersion = mojoVersion;
this.additionalProperties = additionalProperties;
this.triggers = triggers;
}

Command Line Output of .jar is Different than its Output When Run by C# Code

I have a .jar file named "DynamicContentLoader.jar" that executes a Java process that connects to a web page, using HtmlUnit, and prints its Html document via System.out.println();. This Process takes one argument from the command line: the URI of the webpage needed to be retrieved.
Code of the Java process thats exported to the .jar file:
import java.io.IOException;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
public class DynamicContentLoader {
public static void main(String[] args) {
java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF);
String s = DynamicContentLoader.loadHtml("https://query.nytimes.com/search/sitesearch/?action=click&contentCollection&region=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/Donald%20Trump");
System.out.println(s);
}
public static String loadHtml(String url) {
final WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setCssEnabled(false); //if you don't need css
webClient.getOptions().setThrowExceptionOnScriptError(false); // stop process breaking exception throws
HtmlPage page;
try {
page = webClient.getPage(url);
webClient.waitForBackgroundJavaScript(20 * 1000); /* will wait JavaScript to execute up to 5s */
String pageAsXml = page.asXml();
webClient.close();
return pageAsXml;
} catch (FailingHttpStatusCodeException | IOException e) {
return null;
}
}
}
Next, I execute this .jar within a Mono project with a class that uses a Process Object to execute the .jar, read its StandardOutput stream into a StringBuilder, then create and return an HtmlAgilityPack.HtmlDocument object from StringBuilder.ToString();:
using System;
using System.Diagnostics;
using System.Text;
using HtmlAgilityPack;
namespace Search {
public static class DynamicContentLoader {
// path of .jar file in ProjectDirectory/Resources/.jar
readonly static string jarPath =
AppDomain.CurrentDomain.BaseDirectory +
"Resources/DynamicContentLoader.jar";
public static HtmlDocument LoadDynamicWebPage(string url) {
var startInfo = new ProcessStartInfo("java", #" -jar "
+ jarPath + " \'" + url + "\'");
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
var javaProcess = new Process();
javaProcess.StartInfo = startInfo;
javaProcess.Start();
var output = new StringBuilder();
while (!javaProcess.HasExited) {
output.Append(javaProcess.StandardOutput.ReadToEnd());
}
if (output.Length > 0) {
var doc = new HtmlDocument();
doc.LoadHtml(output.ToString());
// looking see if correct Html doc
Console.WriteLine(doc.DocumentNode.InnerHtml);
return doc;
}
return null;
}
}
}
My issue is that when I run the .jar from the command line,
"java -jar path/to/file/DynamicContentLoader.jar 'some uri'"
I get the correctly loaded Html doc/string. However, my C# code above returns a different, incomplete Html doc/string, or even crashes with exceptions like:
Exception in thread "main" java.lang.reflect.InvocationTargetException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
atsun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

at java.lang.reflect.Method.invoke(Method.java:497)
atorg.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58)
Caused by: com.gargoylesoftware.htmlunit.ScriptException: TypeError:
Cannot find function all in object function Promise() { [native code] }
Does anyone know what may cause the difference in behavior between these two different execution methods or what will fix this issue?

Calling python module from Java

I want to call a function from a python module from Java using "PythonInterpreter" and here's my Java code
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("import sys\nsys.path.append('C:\\Python27\\Lib\\site-packages')\nimport helloworld");
PyObject someFunc = interpreter.get("helloworld.getName");
PyObject result = someFunc.__call__();
String realResult = (String) result.__tojava__(String.class);
System.out.println(realResult);
and the Python code (helloworld.py) is below:
from faker import Factory
fake = Factory.create()
def getName():
name = fake.name()
return name
The problem I'm facing is while I'm calling interpreter.get when it returns a null PyObject.
Any idea what's going wrong? The python code runs fine from IDLE
EDIT
I just did a bit of change in the code as below
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("import sys\nsys.path.append('C:\\Python27\\Lib\\site-packages')\nimport helloworld");
PyInstance wrapper = (PyInstance)interpreter.eval("helloworld" + "(" + ")");
PyObject result = wrapper.invoke("getName()");
String realResult = (String) result.__tojava__(String.class);
System.out.println(realResult);
and I introduced a class in my python module
from faker import Factory
class helloworld:
def init(self):
fake = Factory.create()
def getName():
name = fake.name()
return name
Now am getting the error below
Exception in thread "main" Traceback (innermost last):
File "<string>", line 1, in ?
TypeError: call of non-function (java package 'helloworld')

You cannot use python attribute access in PythonInterpreter.get. Just use attribute name to get the module, and retrieve attribute from it.
(EDIT PART) Python code is totally broken. Please see the proper example below. And, of course, www.python.org.
(EDIT PART) First parameter of PyInstance.invoke should be method name.
Below you can find working code sample for both cases
Main.java
import org.python.core.*;
import org.python.util.PythonInterpreter;
public class Main {
public static void main(String[] args) {
test1();
test2();
}
private static void test1() {
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("import hello_world1");
PyObject func = interpreter.get("hello_world1").__getattr__("get_name");
System.out.println(func.__call__().__tojava__(String.class));
}
private static void test2() {
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("from hello_world2 import HelloWorld");
PyInstance obj = (PyInstance)interpreter.eval("HelloWorld()");
System.out.println(obj.invoke("get_name").__tojava__(String.class));
}
}
hello_world1.py
def get_name():
return "world"
hello_world2.py
class HelloWorld:
def __init__(self):
self.world = "world"
def get_name(self):
return self.world
