Update Spring Boot Version and Adjust Dependencies

[tacu90]

Summary

This pull request addresses issues related to outdated Spring Boot version and incorrect dependencies in the Spring initializer commands.

Changes Made

1. Update Spring Boot Version:

   • The commands previously used Spring Boot version 3.1.3, which is no longer available on start.spring.io.
   • Updated the Spring Boot version to 3.3.2.

   curl https://start.spring.io/starter.tgz -d type=maven-project -d dependencies=web -d baseDir=simple-microservice -d bootVersion=3.3.2 -d javaVersion=17 | tar -xzvf -

2. Adjust Dependency for Cloud Gateway:

   • Changed the dependency from cloud-gateway to cloud-gateway-reactive.
   • The cloud-gateway dependency was incorrectly loading spring-cloud-starter-gateway-mvc instead of spring-cloud-starter-gateway, causing mismatches in application.yml and gateway malfunctions.

   <dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-gateway</artifactId>
   </dependency>

Reason for Changes

• Spring Boot Version Error:
  Running the command with version 3.1.3 results in a Bad Request error due to the version being outside the compatibility range. Below is the error message encountered:

  {
      "timestamp":"2024-07-24T07:15:12.386+00:00",
      "status":400,
      "error":"Bad Request",
      "message":"Invalid Spring Boot version '3.1.3', Spring Boot compatibility range is >=3.2.0",
      "path":"/starter.tgz"
  }

• Dependency Issue:
  The incorrect cloud-gateway dependency was leading to the inclusion of spring-cloud-starter-gateway-mvc instead of spring-cloud-starter-gateway, causing configuration issues and non-functional gateway setup.
