Ever faced this warning when starting Spring Boot?
warning: The AWS SDK for Java v1.11.x has been marked as maintenance mode...
Are you developing applications that use Amazon S3? Setting up a local development environment can be tricky. In this guide, I'll show you how to use MinIO as a local S3-compatible storage solution, with a special focus on AWS SDK for Java V2 implementation.
This article was originally published on KINTO Technologies Blog.

What you'll learn:

Setting up MinIO with Docker Compose
Implementing AWS SDK for Java V2
Handling GitHub Actions integration
Best practices and troubleshooting tips

Here's a quick look at what we'll build:

services:
  minio:
    container_name: minio_test
    image: minio/minio:latest
    command: ['server', '/data', '--console-address', ':9001']
    ports:
      - "9000:9000"
      - "9001:9001"

The complete guide includes working examples and code snippets that you can use right away in your projects.

Zero Config Spring Batch: Just Write Business Logic

y m — Sat, 04 Jan 2025 17:16:10 +0000

Hi r/SpringBoot community! I created a Spring Boot 3 Batch starter focused on tasklet-pattern jobs with zero configuration, and wrote a detailed technical blog post about it. The Gradle wrapper automatically downloads JDK - just clone and build.

Project Links

GitHub: https://github.com/kinto-technologies/SpringBoot3BatchStarter
Technical Blog (English): https://blog.kinto-technologies.com/posts/2024-12-25_copy_paste_spring_batch5_boot3

Quick Start

Clone the repo (only Git needed)
Use or modify the sample service

  public class SampleService {
      public void process() {
          log.info("--- Starting batch process ---");
          // Your business logic here
          log.info("--- Batch process completed ---");
      }
  }

3 Run wrapper to create executable jar: ./gradlew

Features

Auto-downloads JDK via Gradle wrapper
Creates executable jar with default task
Zero Spring Batch configuration
Ready-to-use service class template
Logging configured

Blog Post Covers

Design decisions behind the zero-config approach
Why I chose the tasklet pattern
Detailed implementation examples
Step-by-step usage guide

Looking forward to your feedback on both the project and the technical write-up!
