Organize It - [Todo Manager]

Overview

OrganizeIt is a Todo Manager application built using Spring Boot.

I have adhered to industrial standard coding practices. This includes implementing a three-layer architecture for separation of concerns & to ensure the code is maintainable and understandable, utilizing global exception handling to ensure consistent error management, and employing a logging mechanism for effective debugging and monitoring. By integrating technologies such as Java, Spring Boot, Hibernate, JPA, and MySQL, I have ensured that the application is robust, maintainable, and scalable, meeting the high standards of professional software development.

The application demonstrates three different methods for data storage:

1. Hibernate (used as Primary)
2. Spring JDBC
3. In-memory using data structures

Features

• In-Memory Data Storage: Quick and easy setup for testing and development purposes.
• Spring JDBC: Demonstrates how to interact with a relational database using Spring's JDBC support.
• Hibernate: Uses Hibernate ORM for database interactions, leveraging JPA annotations.
• Global Exception Handling: Centralized exception handling using @ControllerAdvice.
• Logging: Integrated logging using SLF4J.
• Three-Layer Architecture: Follows a clear separation of concerns with Controller, Service, and Repository layers.

Technologies Used

• Java: The core programming language utilized for developing the application's business logic and implementing various features.
• Spring Boot: Simplifies the setup and development of Spring-based applications, providing auto-configuration and embedded servers to accelerate development.
• In-memory Data Structure: Used for quick, lightweight storage during development and testing, without persistent storage requirements.
• Spring JDBC: Provides a straightforward approach for interacting with relational databases using SQL, useful for managing database connections and executing queries.
• Hibernate: An ORM tool that maps Java objects to database tables, offering a higher-level abstraction for database operations and simplifying CRUD operations.
• JPA (Java Persistence API): Provides a specification for managing relational data in Java applications. Used with Hibernate to define entities and manage persistence operations in a standardized way.
• MySQL Database: A widely-used relational database management system that stores application data efficiently, supports SQL for querying, and integrates seamlessly with Spring Boot and JPA.

Endpoints Exposed

• GET /todos : Retrieve all todos
• GET /todos/{id} : Retrieve a single todo by ID
• POST /todos : Create a new todo
• PUT /todos/{id} : Update an existing todo
• DELETE /todos/{id} : Delete a todo by ID

Screenshots

1.) Success Response:

Create Todo	Get Todo

Update Todo	Get All Todos

Delete Todo	Get All Todos (checking again after deleting todo)

2.) Bad Response [Exception Handling]:

Get Todo (with wrong todo id)	Update Todo (with wrong todo id)

Delete Todo (with wrong todo id)
