JavaとPythonのHello World(http getバージョン)

■前提

Javaのフレームワーク：spring boot
Pythonのフレームワーク：fastapi

■本題

Java

ファイル

HelloApplication.java

package com.example.hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloApplication {

	public static void main(String[] args) {
		SpringApplication.run(HelloApplication.class, args);
	}
}

GreetingController.java

package com.example.hello;

import java.util.concurrent.atomic.AtomicLong;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {
	private static final String template = "Hello, %s!";
	private final AtomicLong counter = new AtomicLong();

	@GetMapping("/greeting")
	public Greeting greeting(@RequestParam(value="name", defaultValue="world") String name) {
		return new Greeting(counter.incrementAndGet(), String.format(template, name));
	}
}

Greeting.java

package com.example.hello;

public class Greeting {
	private final long id;

	private final String content;

	// コンストラクタ
	public Greeting(long id, String content) {
		this.id = id;
		this.content = content;
		this.higaGreeting();
		Greeting.higaGreeting2();
	}

	// Getters
	public long getId() {
		return id;
	}
	public String getContent() {
		return content;
	}
}

Python

python -m venv venv

pip install fastapi

pip install uvicorn[standard]

main.py

from fastapi import FastAPI
app = FastAPI()
@app.get("/")
async def root():
    return {"message":"Hello World"}
