package com.main.AngBoot.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

import com.main.AngBoot.bean.Product;
import com.main.AngBoot.service.ProductHardcodedService;
@CrossOrigin(origins="http://localhost:4200")
@RestController
public class ProductController {
	@Autowired
	private ProductHardcodedService prodService;
	
	@GetMapping("/users/{productname}/prodct")
	public List<Product> getAllProducts(@PathVariable String productname){
		return prodService.findAll();
		
	}
	@DeleteMapping("/users/{productname}/prodct/{id}")
	public ResponseEntity<Void> deleteProduct(@PathVariable String productname,
			@PathVariable long id){
		Product product = prodService.deleteById(id);
		if (product != null) {
			return ResponseEntity.noContent().build();
		}
		return ResponseEntity.notFound().build();
	}
