The beans endpoint provides information about the application’s beans.

Retrieving the Beans

To retrieve the beans, make a GET request to /actuator/beans, as shown in the following curl-based example:

$ curl 'http://localhost:8080/actuator/beans' -i -X GET

The resulting response is similar to the following:

HTTP/1.1 200 OK
