spring-autoconfiguration-example

An example of loading configuration objects using the @EnableAutoConfiguration annotation.

The example contains a simple Spring Boot rest service with several endpoints. At runtime, via auto-configuration, an endpoint that returns a list of all endpoints in the application is automatically added.

Running the Example

1. Start the example by running the following Gradle command:

    $ ./gradlew bootRun
   

2. Execute the following command to hit the endpoint added at runtime via auto-configuration:

    # curl -v http://localhost:8080/endpoints
   

   If successful you will see the following:

    *   Trying ::1...
    * TCP_NODELAY set
    * Connected to localhost (::1) port 8080 (#0)
    > GET /endpoints HTTP/1.1
    > Host: localhost:8080
    > User-Agent: curl/7.54.0
    > Accept: */*
    >
    < HTTP/1.1 200
    < Content-Type: application/json;charset=UTF-8
    < Transfer-Encoding: chunked
    < Date: Thu, 24 May 2018 03:39:18 GMT
    <
    * Connection #0 to host localhost left intact
    ["/bar1","/bar","/bar2"]
   

3. Notice that only the bar endpoints have been returned due to the FooController being annotated with @ExcludeEndpointListing.
