Integrate Python code from Spring Boot project

I have python code. I run it using python -m base-package arguments
I want to run this project from a spring boot project and use the output given by the python. I could not find any simple tutorial, is there any simple way to get this done?

Try execute your command with this:
private String getResponseFromCommand(String command) throws IOException {
Process process = exec(command);
InputStream in = process.getInputStream();
String response = new BufferedReader(
new InputStreamReader(in))
.lines().collect(Collectors.joining("\n"));
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
return response;
}
I wrote this for running docker commands and getting feedback from them. It should work for any command though.

Can't Change File Permissions from Within a Java Program

I have a Java program, that on runtime, extracts some executables to a specific folder, and tries to run them. Of course, before running the executable, its permissions need to be changed. For that purpose, I am using the following piece of code:
public static void changePermissions(String filename,String path){
String[] cmd=new String[3];
cmd[0]="chmod";
cmd[1]="u+x";
cmd[2]=filename;
BetterRunProcess process=new BetterRunProcess();
process.runProcessBuilderInDifferentDirectory(cmd,path,1,0,0,"");
}
In the above code snippet,the variable path contains the path to the executable, and filename is the name of the executable. The line:
process.runProcessBuilderInDifferentDirectory(cmd,path,1,0,0,"");
executes the command "chmod u+x ...". On my own computer, the code works just fine, but when I run it on someone else's computer, the following error is thrown:
chmod: changing permissions of deviceQuery.out. Operation not permitted.
Can someone figure-out what might be the problem behind this?
Here is some more code, that might be helpful.
public void runProcessBuilderInDifferentDirectory(String[] cmd,String path,int printToConsole,int printToExternalFile,int append,String fileName){
ProcessBuilder builder;
if(cmd.length==1) builder=new ProcessBuilder(cmd[0]);
else if(cmd.length==2) builder=new ProcessBuilder(cmd[0],cmd[1]);
else if(cmd.length==3) builder=new ProcessBuilder(cmd[0],cmd[1],cmd[2]);
else if(cmd.length==4) builder=new ProcessBuilder(cmd[0],cmd[1],cmd[2],cmd[3]);
else builder=new ProcessBuilder(cmd[0],cmd[1],cmd[2],cmd[3],cmd[4]);
builder.directory(new File(path));
try {
Process pr=builder.start();
if(printToConsole==1) printToConsole(pr);
if(printToExternalFile==1) printToExternalFile(pr,fileName,append);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Thanks!

Run your java code from that user which has the permission for that file.

How to find TextEdit on Mac?

My Java app will detect file extension and open it in Windows using wordpad, like this :
public static Process Display_File(String File_Path)
{
String Command,Program,Suffix=File_Path.toLowerCase();
Process process=null;
if (Suffix.endsWith("txt") || Suffix.endsWith("json")) Program="C:\\Program Files (x86)\\Windows NT\\Accessories\\word_pad.exe ";
Command=Program+"\""+File_Path+"\"";
try { process=Runtime.getRuntime().exec(Command); }
catch (Exception e) { e.printStackTrace(); }
return process;
}
But it won't work on Mac, I know there is TextEdit.app on Mac, so how to change the above code to run it on Mac ?
After the change, it looks like this :
public static Process Display_File_On_Mac(String File_Path)
{
String Command,Program,Suffix=File_Path.toLowerCase();
Process process=null;
if (Suffix.endsWith("txt") || Suffix.endsWith("json")) Program="/Applications/TextEdit.app ";
Command=Program+"\""+File_Path+"\"";
try { process=Runtime.getRuntime().exec(Command); }
catch (Exception e) { e.printStackTrace(); }
return process;
}
But I got this error :
java.io.IOException: Cannot run program "/Applications/TextEdit.app": error=13, Permission denied
How to fix it ?

Starting macOS Catalina system applications moved to /System/Applicatyions folder: https://support.apple.com/HT210650
So, new path to TextEdit is /System/Applications/TextEdit.app/Contents/MacOS/TextEdit

On El-capitan, giving the below path worked for me:
Program="open /Applications/TextEdit.app/Contents/MacOS/TextEdit";
You can Navigate into the TextEdit.app folder from a terminal window and make sure you have the executable in the right place before trying it out.
Also, you need to change the setting of command like this:
Command = Program+ " "+File_Path;

Java - Printing to cmd

So my problem here is that I'm not too sure how to print a set of commands to cmd. I have a batch file that runs a Minecraft server, and I need to be able to run commands through the command prompt that shows up when I run the batch file, which will in turn perform commands to the server.
Here is my code so far:
package com.Kaelinator;
import java.io.IOException;
public class ServerManager {
public static void main(String[] args){
try {
System.out.println("Opening");
Runtime runTime = Runtime.getRuntime();
Process process = runTime.exec("cmd /C start /min " + "C:/Users/Owner/Desktop/rekt/Run.bat");
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
//System.out.println("Closing");
//process.destroy();
} catch (IOException e){
e.printStackTrace();
}
}
}
Yes, I understand that all this does so far is open the batch file. :P I am expecting something like this that I need to add to my code:
process.InputStream(command1);
But I am certain that there is more to it, something along the lines of bufferedWriters or something like that...
Whenever I try to get answers from Google, the answers always have a whole load of extra code, or have something completely different about them.
Thanks!

Running a .cmd file through Java code

I am trying to run a .cmd program from Java. Doesn't run.
I'm using Runtime.exec as advised in some other posts.
public void mouseClicked(MouseEvent arg0) {
Runtime runtime = Runtime.getRuntime();
String path = "E:/Marvin/Marvin_Cleanup.CMD";
try {
runtime.exec(path);
} catch (Exception e1) {
e1.printStackTrace();
}
}

Im not familiar with windows executeables but using the process builder combined with that url should work fine.
http://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html

If you call further batches from your batch file you might need to use cmd /c prefix. https://superuser.com/questions/712279/commands-run-in-a-batch-file-only-when-writing-cmd-c-before
String path = "cmd /c E:/Marvin/Marvin_Cleanup.CMD";
