An example of retrieving data from an off-heap Chronicle Map in a Spring WebFlux application.
The example application consists of a webservice that serves product data from a Redis database. When product data is retrieved it is cached using Chronicle Map and returned from cache on subsequent requests.
Run the following command to build the example application:
./gradlew clean build
Follow the steps below to run the example:
-
Run the following command to start the application and a Redis database:
./gradlew bootRunLocal -
Run the following command to retrieve a product:
curl "http://localhost:8080/products/10"If successful, you will see the following response:
{"id":"10","name":"Product10","description":"Product10 Description","active":false,"start_date":"2021-01-01T00:00Z","end_date":"2021-01-31T00:00Z"} -
There are also several cache management endpoints exposed via the Cache Management Actuator Endpoint:
Get Cached Value
Gets the value of the key in the cache.
curl "http://localhost:8077/actuator/cache/values/2"Invalidate Cached Value
Removes the value of the key in the cache.
curl -X "POST" "http://localhost:8077/actuator/cache/values/2/invalidate"Refresh Cached Value
Refreshes the value of the key in the cache with the latest value in Redis.
curl -X "POST" "http://localhost:8077/actuator/cache/values/2/refresh"
