Platform Http Main

Since Camel 4.0

The camel-platform-http-main is an embedded HTTP server for camel-main standalone applications.

The embedded HTTP server is using VertX from the camel-platform-http-vertx dependency.

Enabling

The HTTP server for camel-main is disabled by default, and you need to explicitly enable this by setting camel.server.enabled=true in application.properties.

Auto-detection from classpath

To use this implementation all you need to do is to add the camel-platform-http-main dependency to the classpath. Then, the platform http component should auto-detect this.

Uploading and downloading files

The embedded HTTP server comes with a set of features out of the box (management, development and user services), that can be enabled.

These features are as follows:

  • / - Serving static content such as html, javascript, css, and images to make it easy to embed very small web applications.

  • /observe/info - Report basic information about Camel

  • /observe/health - Health checks

  • /observe/jolokia - To use Jolokia to expose JMX over HTTP REST

  • /observe/metrics - To provide OTEL metrics in prometheus format

  • /q/dev - Developer console that provides a lot of statistics and information

  • /q/upload - Uploading source files, to allow hot reloading.

  • /q/download - Downloading source files, to allow inspecting

  • /q/send - Sending messages to the Camel application via HTTP

You configure these features in the application.properties file using the camel.server.xxx and camel.management.xxx options.
