How to Return a ZIP File in a Micronaut Controller
- Micronaut, a JVM-based framework, is ideal for building high-performance microservices and serverless applications.
- Micronaut utilizes compile-time annotation processing, reducing memory usage and startup time compared to traditional frameworks.
- Key features include compile-time dependency injection, fast startup time, seamless GraalVM integration, and support for reactive programming.
- To return a ZIP file in a Micronaut controller, dependencies like micronaut-http-server-netty and micronaut-inject are needed.
- A Java controller class named ZipDownloadController is created to handle the zip file generation and download logic.
- The controller method downloadZip() dynamically generates a ZIP file with two text files and returns it as a downloadable byte array.
- Accessing the /download/zip endpoint prompts a sample.zip file download containing hello.txt and data/info.txt.
- Micronaut's efficiency makes it suitable for serving dynamically created ZIP files, enhancing server-side operations.
- By following the provided code examples, developers can implement ZIP file downloads seamlessly in Micronaut applications.
- Overall, Micronaut's lightweight nature and performance optimizations make it a compelling choice for modern Java development.
