+# ActionModelsGenerator
+
+## Project Overview
+
+The `ActionModelsGenerator` is an IntelliJ Platform Plugin designed to automate the generation of Java `ActionBean` and Data Transfer Object (DTO) classes from a database schema. This plugin integrates directly into the IntelliJ IDE, allowing developers to select a database table and generate corresponding Java classes based on predefined FreeMarker templates.
+
+**Key Features:**
+*   **Database Schema Introspection:** Utilizes IntelliJ's database tools to read table and column metadata.
+*   **Code Generation:** Generates `ActionBean` and DTO classes using FreeMarker templates.
+*   **Template-driven:** Customizable code generation via FreeMarker templates (`actionBean.ftl`, `actionBean.extend.ftl`, `actionDTO.ftl`, `actionDTO.extend.ftl`).
+*   **IDE Integration:** Provides a context menu action ("Generate Action Models") in the Database View for easy access.
+
+**Core Technologies:**
+*   **Java:** Primary development language.
+*   **Kotlin:** Configured in `build.gradle.kts`, indicating potential for Kotlin usage.
+*   **Gradle (Kotlin DSL):** Build automation system.
+*   **IntelliJ Platform SDK:** For IDE integration and database interaction.
+*   **FreeMarker:** Templating engine for code generation.
+
+## Building and Running
+
+This project is an IntelliJ Platform Plugin built with Gradle.
+
+**Build the Plugin:**
+To build the plugin, use the following Gradle command:
+```bash
+./gradlew build
+```
+This will produce a `.zip` plugin artifact in the `build/distributions` directory.
+
+**Run the Plugin in a Development IDE:**
+To run a new IntelliJ IDE instance with this plugin installed for development and testing:
+```bash
+./gradlew runIde
+```
+Alternatively, you can use the "Run IDE with Plugin" run configuration provided in the `.run` directory within IntelliJ IDEA.
+
+## Development Conventions
+
+*   **Language:** Primarily Java, with Kotlin support configured.
+*   **Build System:** Gradle with Kotlin DSL (`.gradle.kts` files).
+*   **Code Generation:** FreeMarker templates are located in `src/main/resources/templates/`. Modifications to these templates will change the generated code structure.
+*   **IntelliJ Platform APIs:** Development involves using IntelliJ Platform SDK for UI actions, virtual file system operations, and database schema access.
+*   **Action Definition:** New actions are defined in `src/main/resources/META-INF/plugin.xml`.
