Dropwizard is a Java framework for building web applications and RESTful APIs. By default, Dropwizard doesn't have built-in support for serving static HTML files directly. However, you can use a Dropwizard module called "dropwizard-assets" to serve static resources, including HTML files.

To serve static HTML files using Dropwizard, follow these steps:

  1. Add Dependencies: Add the "dropwizard-assets" dependency to your pom.xml file:

    <dependency> <groupId>io.dropwizard.modules</groupId> <artifactId>dropwizard-assets</artifactId> <version>2.0.26</version> <!-- Replace with the appropriate version --> </dependency>
  2. Configuration: Configure the static assets in your Dropwizard application's configuration file (e.g., config.yml):

    # config.yml assets: overrides: "/": "index.html" # Map the root URL to the index.html file resourceBasePath: "src/main/resources/assets" # Path to the directory containing your static assets
  3. Place Static Files: Place your static HTML files (e.g., index.html) in the specified directory (src/main/resources/assets in the example above).

  4. Application Class: In your Dropwizard application class, register the AssetsBundle to serve the static assets:

    import io.dropwizard.Application; import io.dropwizard.Configuration; import io.dropwizard.assets.AssetsBundle; import io.dropwizard.setup.Bootstrap; import io.dropwizard.setup.Environment; public class MyApplication extends Application<Configuration> { public static void main(String[] args) throws Exception { new MyApplication().run(args); } @Override public void initialize(Bootstrap<Configuration> bootstrap) { // Add the AssetsBundle to serve static assets bootstrap.addBundle(new AssetsBundle("/assets", "/static", null, "assets")); } @Override public void run(Configuration configuration, Environment environment) { // Add your resources, health checks, etc., here } }

    In the example above, the AssetsBundle is configured to serve assets from the /assets URL path and map them to the /static path in your application.

  5. Accessing Static Files: With the above setup, you can access your static HTML files by navigating to the corresponding URLs. For example, if you have an index.html file in the assets directory, you can access it at http://localhost:8080/static/index.html (assuming your Dropwizard application runs on port 8080).

That's it! Your Dropwizard application should now be serving static HTML files. Remember that the configuration and file paths can be adjusted based on your project's needs.
