Can you improve and make changes to my ServiceFactory code for a Spring Boot backend $($IntelliJ$)?"$

Question Details: $"$I$\text{'}$m building a backend for a blog application using Spring Boot and PostgreSQL in IntelliJ, and I've created a ServiceFactory class to handle service instantiation. The factory uses a map of service creators to flexibly retrieve services with varying dependencies.

Could you review this code and make direct improvements to optimize it for:

Error Handling: Adding better handling for missing services or invalid arguments.

Spring Boot Integration: Using Spring Boot's DI framework if possible to reduce complexity or remove the factory if it can be simplified.

Code Structure: Enhancing readability, efficiency, and maintainability. package com.example.blog.services;

import com.example.blog.repositories.FaqRepository;

import com.example.blog.repositories.UserRepository;

import com.example.blog.repositories.PostRepository;

import org.modelmapper.ModelMapper;

import java.util.HashMap;

import java.util.Map;

import java.util.function.Function;

public class ServiceFactory $\{$

$//$Map to hold service creators for flexible instantiation

private static final Map, Function$>$serviceCreators $=$new HashMap$<>()$;

static $\{$

$//$Register each service with the required dependencies

serviceCreators.put$($FaqService$.$class, args $->$FaqService$.$getInstance$(($FaqRepository$)$args$[0],($ModelMapper$)$args$[1]))$;

serviceCreators.put$($UserService$.$class, args $->$UserService$.$getInstance$(($UserRepository$)$args$[0]))$;

serviceCreators.put$($PostService$.$class, args $->$PostService$.$getInstance$(($PostRepository$)$args$[0],($ModelMapper$)$args$[1]))$;

$\}$

$//$Type$-$safe method with variable arguments for dependencies

public static T getService$($Class serviceClass, Object... args$)\{$

Function creator $=$serviceCreators$.$get$($serviceClass$)$;

if $($creator $!=$null$)\{$

return serviceClass.cast$($creator$.$apply$($args$))$;

$\}$

throw new ServiceNotFoundException$("$Service not found for: $"+$serviceClass$.$getSimpleName$())$;

$\}$

$\}$

modify the given code and give me the new code. I am creating a blogpost application and for that I need html and css code that too a professional format so that my web application looks amazing and professional. I need help with these pages. I am connecting it with the backend too $,$so give me responsive pages.Make sure to include everything in the code and create professional, eye$-$catching pages. Home Page
