+Mockup service for middleware testing.

+### Running the application on a local machine
+For Intellij:
+Plugins:
+settings -> plugins -> install lombok plugin
+settings -> annotation processors -> enable annotation processing
+
+A connection to a Redis database is expected to run the application successfully. You need to download and run Redis DB on
+your local machine with default values localhost 6379.
+
+You can also run the application via Docker.
+#### docker-compose up --build -d
+
+However, you need either to run it with Docker-compose ensuring that all containers are within a network or start application locally.
+In order to change environment two properties must be changed.
+
+1) data-access.properties - property redis.host
+2) logback.xml - configuration/appender/host element value
+
+If application is to be run locally, both of above should be set to "localhost"
+If application is to be run in docker environment, both should be set to name of a redis container (by default "redis")
+
+Docker automaticly translates container name to IP address, considering all containers are within same network.
+Try to avoid using any symbols in names of containers, because it may cause that URL exception to be thrown. Instead use letters only.
+
+### Operations on Redis DB
+
+Use Redis CLI or attach to Redis docker image in order to manually operate on DB.
+
+#### docker exec -it mockedservices_redis-server redis-cli
+Attach to redis server image and open a redis client. 
+
+Useful redis-cli commands:
+###### KEYS *
+Show all keys in the db.
+###### TYPE key
+Show key type.
+###### LRANGE key start stop
+Display elements from the list.
+###### LLEN key
+Display list length.
+###### SMEMBERS key
+Display elements from hashSet.
+Logs can be found in lists with names logstash_yyyy-mm-dd.
