Running a Python script from Spring-Boot Web Application on embedded Tomcat

I dug the internet a lot and found the solution.

One can do this using the following commands:

String fetching = "python " + "c:\\Fetch.py \"" + songDetails + "\"";
String[] commandToExecute = new String[]{"cmd.exe", "/c", fetching};
Runtime.getRuntime().exec(commandToExecute);

A better approach would be to treat the Python script as an external service to be called rather than a file to be executed. In this case, I would strongly advise Flask as a light-weight framework.

A simple flask application would look something like this:

from flask import Flask, jsonify
app = Flask(__name__)

@app.route('/')
def hello():
    # Call your script method here
    return jsonify(success=True)

if __name__ == '__main__':
    app.run(debug=True)

In the case of local development, you can run this application with the shell command "python filename.py". By default, you can call this service by http://127.0.0.1:5000/ using the preferred Java method of yours.

How to use Jython with Spring Boot - Dreamix

July 16, 2024 - I used the first one in the Spring tutorial - https://spring.io/guides/gs/spring-boot/ 2.Then we need Jython (https://www.jython.org/ ). I installed version 2.7.1 to my PC and added the dependency to the pom.xml like that: <dependency> <groupId>org.python</groupId> <artifactId>jython</artifactId> <version>2.7.1</version> </dependency> An easier way would be to use jython-standalone artifact here which doesn’t require Jython installation and keeps most of the libraries in the JAR but it has limited functionality and doesn’t allow you to use external modules available through pip.

Hello everyone.. i want to ask is it possible to add a python script like this?

I have a functional spring boot + react app for users and they already using it. But they have a new change request to add a button to download the file as an excel with templates and data was fetch from the db. My friend help me by building a python script to generate this file (since we think python is good for working with data)

JYthon is a Java implementation of python 2.7. Beyond that, you're into executing an external process from your Spring backend. https://www.baeldung.com/java-process-api Either way is probably a lot more hassle than simply re-writing that Python in Java. I guess a third approach would be to turn that python script into a web app using Flask or something, and have your Spring backend call it. But it's all a lot of fuss, with you now having to manage failure modes which simply wouldn't happen if it was all done in-process. Having some Java do it natively in the Spring backend is far simpler. Apache POI makes working with Excel easier, and I think there are other libraries around.

8. Remoting — Spring Python v1.2.1.FINAL documentation

Running the remote service on another server only requires us to edit the client’s application context, changing the URL to get to the service. All without telling the client and server code. No. Again, Spring Python provides you the freedom to do things using the IoC container, or programmatically. To do the same configuration as shown above looks like this: from springpython.remoting.pyro import PyroServiceExporter from springpython.remoting.pyro import PyroProxyFactory # Create the service remoteService = Service() # Export it via Pyro using Spring Python's utility classes service_exporter = PyroServiceExporter() service_exporter.service_name = "ServiceName" service_exporter.service = remoteService service_exporter.after_properties_set() # Get a handle on a client-side proxy that will remotely call the service.

you are not putting your HelloWorld.py file into the container that is why its not working what you need to do is add HelloWorld.py into the container and also make sure python is installed inside the container.

ADD target/dockerMaster.jar dockerMaster.jar
