Feature Proposal

Entity Generation

• Allow users to generate JPA entities from database tables or existing classes.

Entity-to-Table Mapping

• Implement tools to assist in configuring the mappings between entities and database tables, including annotations like @Entity, @Table, @OneToMany, etc.

JPQL Query Generation

• Add the ability to generate or validate JPQL (Java Persistence Query Language) queries.

Migration Scripts

• Implement tools to assist in generating database migration scripts (similar to Flyway or Liquibase).

Validation & Code Generation

• Offer validation for entity classes and automatic generation of getters/setters, constructors, etc.

Reverse Engineering

• Add reverse engineering from database tables to generate entities or repositories.

Backend Components

Entity Generation Engine

• Use a Java process (possibly leveraging a Maven/Gradle task) to handle the JPA entity generation and reverse engineering.

Database Connectivity

• Use JDBC or another database library to connect to databases and fetch schema details.

Query Validation and Execution

• Add backend code to validate and optionally execute JPQL queries.

Frontend Integration

Database Schema & Entity Mapping UI

• Provide a UI for browsing the database schema, creating JPA entities, and mapping relationships. We are using the VS Code Webview API for this.

Command Palette Integration

• Implement a command palette for JPA-related commands like "Generate Entity from Table," "Generate JPQL Query," etc.
