Spring Boot Code Generator - CRUD REST API

The "Spring Boot Code Generator: CRUD REST API Tool" is a web-based tool designed to generate CRUD (Create, Read, Update, Delete) REST APIs for Spring Boot applications. By entering the entity's name and its fields, the tool provides ready-to-use code for the Entity, Controller, Service, and Repository layers, making it easier to set up a new Spring Boot application with basic CRUD functionality.

This code generator tool streamlines the initial setup of a Spring Boot CRUD application by generating the essential boilerplate code. By reducing repetitive tasks, developers can focus on implementing more specific functionalities tailored to their application's needs.

Still, I am working on this tool to make it better.

Spring Boot Code Generator: CRUD REST API Tool Documentation 

Overview 

The "Spring Boot Code Generator: CRUD REST API Tool" is a web-based tool designed to generate CRUD (Create, Read, Update, Delete) boilerplate code for Spring Boot applications. By entering the entity's name and its fields, the tool provides ready-to-use code for the Entity, Controller, Service, and Repository layers, making it easier to set up a new Spring Boot application with basic CRUD functionality. 

Usage Guide 

1. Specify the Entity Name 

Enter the desired entity's name in the "Entity Name" input field. 

2. Define the Entity's Fields 

By default, one field input group is provided. For each field, specify its name and type. To add more fields, click on the "Add Field" button. To remove a field, click the "Remove" button next to the field. 

3. Generate Code 

Once all details are provided, click the "Generate Code" button. The tool will display the generated code in the respective sections. 

4. Copy Generated Code 

Click the "Copy" button next to each section to copy the code to your clipboard. Paste it into the appropriate files in your Spring Boot project. 

Interface Description 

The web interface consists of: 

Entity Name Input: For specifying the name of the entity. 

Fields Input: Where users can define the fields of their entity. Each field consists of a name and its associated type. 

Generate Button: Upon pressing this button, the tool will generate the boilerplate code based on the provided input. 

Code Output Areas: Sections where generated code snippets (for Maven dependencies, database configuration, entity, controller, service, and repository) will appear. 

Features 

Dynamic Field Addition: 

Users can dynamically add new fields to the entity without any limitation. 

Field Removal: 

Any added field can be removed if deemed unnecessary. 

Code Generation: 

Generates necessary CRUD boilerplate code for Spring Boot, which includes: 

• Maven Dependencies 
• Database Configuration 
• Entity Code 
• Controller Code 
• Service Code 
• Repository Code 

Copy Functionality: 

Next to each generated code section, there is a "Copy" button allowing users to easily copy the generated code to their clipboard. 

Limitations and Considerations 

Database Configuration: As of now the tool supports MySQL, PostgreSQL, and H2 databases. If you are using another database, you'll need to adjust the configuration accordingly. 

Maven Dependencies: The provided Maven dependencies are for a basic Spring Boot CRUD application. Depending on your project's needs, you might need to add or remove certain dependencies. 

Validation & Error Handling: The tool does not currently provide validation for input fields or handle potential errors. For a more robust solution, consider adding these features. 

Advanced Features: For more complex applications, this tool might not provide all the necessary configurations or code structures. It's intended as a starting point for basic CRUD applications. 

Conclusion 

This code generator tool streamlines the initial setup of a Spring Boot CRUD application by generating the essential boilerplate code. By reducing repetitive tasks, developers can focus on implementing more specific functionalities tailored to their application's needs.
