ThingLinks Open Exp Plugin | 中文文档

Open Exp Plugin Overview

Open-Exp-Plugin Sample Marketplace is a plugin repository based on the ThingLinks Open EXP extension point plugin system. It is designed to demonstrate how to develop, extend, and integrate functionalities within the ThingLinks platform. This marketplace provides a variety of plugin examples to help developers quickly get started and understand the powerful capabilities and flexibility of the plugin system.

Features

• Plugin Architecture: Demonstrates the ThingLinks plugin architecture, supporting various plugin development models.
• Hot-Swappable Support: Plugins support dynamic installation and uninstallation at runtime without restarting the main application.
• Multi-Tenant Support: Supports loading different plugins based on tenant ID for customized functionality.
• Modular Design: Plugins and the main application adopt a modular design, supporting the isolation and integration of extension points and plugins.
• Classloader Isolation: Provides Parent First and Self First classloader isolation mechanisms to ensure independence between plugins.

Usage Example

How to Use the Plugin Sample Marketplace

1. Enable Dependencies and Select Plugins: Enable the example related dependencies in the pom.xml file of the open-exp-plugin module.

   

2. Reload Projects: Reload all Maven projects to ensure the dependencies are correctly loaded.

3. Clean and Package: Clean and package the all-package module.

   

4. After Packaging: The plugin packages are by default generated in the exp-plugins directory.

   

5. Start the Main Application: Run the Main class in the example-springboot3 module.

   The main application will automatically load and install the packaged plugins（That is, plugins in the exp-plugins directory）. If you need to reinstall or uninstall plugins, simply call the relevant API.

Notes

Core Features

• Extension Point Interface: Defines multiple extension point interfaces for plugins to implement.
• Multi-Tenant Support: Different tenants can use different plugin implementations, with support for tenant priority sorting and filtering.
• Hot-Swappable Mechanism: Supports dynamic loading and unloading of plugins, enhancing system extensibility and flexibility.
