IMPORTANT: Please be sure that you have first *Portal (Auth n Auth)* and *ContactBaseData* installed and configured!


== Prerequisites
* *howToBuild* documentation read and steps completed
* *howToRun* documentation read
* *application.yml* was copied from [microservice]/src/main/resources/application.yml next to the *.jar into the deployment folder
of each microservice you want to use

CAUTION: Each [microservice] has its *own application.yml*

== Configuration of the system

The backend services are configured in *application.yml* files. If there is an *application.yml* file next to the
**.jar* file of the microservice this very *application.yml* has precedence over the default *application.yml* which resides
inside the jar file. In other words if there is no *application.yml* next to the jar file the default one inside is beeing used.
For reasons of convenience we use the method config-file outside and next to the jar.
After editing an *application.yml* file, you have to restart the microservice for changes to take effect.

Yml-files can be divided into different configuration profiles.
When starting the backend-service one has the possibility to specify
the active profile, if no profile is set the default is beeing used.
The default profile is the one which you most likely want to configure and which you are going
to use. If you want different or more profiles see the following link for further details:
https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-profiles

CAUTION: _Credentials (Username and Password)_ +
All credentials in this yml-files are hidden. Environment variables are used to set
them. Get an environment variable in a yml-file this way `${ENVIRONEMT_VARIABLE}`.
To successfully run the backend service either set the environment variable for the using platform
or replace them in the yml-file.


=== Periodically executed jobs - Cron expression

To execute periodically occuring jobs, Spring uses a form of cron expression.
They don't follow the same format as UNIX cron expressions.

Spring Cron expression consists of six sequential fields:
----
second, minute, hour, day of month, month, day(s) of week
----

.Explenation
[options="header,footer"]
|=======================
|syntax |means            |example        | explanation
|*      |match any        |"* * * * * *"  | do always
|*/x    |every x          |"*/5 * * * * *"| do every five seconds
|?      |no specification |"0 0 0 24 12 ?"| do every Christmas Day
|=======================

.Examples
[options="header,footer"]
|=======================
|syntax                 |means
|"0 0 * * * *"          |the top of every hour of every day.
|"0 */1 * ? * *"        |every minute starting at second 0.
|"0 */5 * ? * *"        |every 5 minutes starting at second 0.
|"*/10 * * * * *"       |every ten seconds.
|"0 0 8-10 * * *"       |8, 9 and 10 o'clock of every day.
|"0 0/30 8-10 * * *"    |8:00, 8:30, 9:00, 9:30 and 10 o'clock every day.
|"0 0 9-17 * * MON-FRI" |on the hour nine-to-five weekdays
|"0 0 0 24 12 ?"        |every Christmas Day at midnight
|=======================

You can use the following generator but keep in mind to *not use the year*.
The spring expression hast to consist of six fields only:

[#secureEndpoints]
=== Secure Endpoints

The main backend (gfsBackendService) is secured by JWTs (JSON-Web-Tokens).
The following services are secured by "Basic Authentication":

* addressImport
* mailExport
* stoerungsauskunftInterface
* SARISInterface

For each of them you will find the following parameters to configure the "Basic Authentication" in the
corresponding *application.yml*:

* *security.endpoint.user* Username for the secure endpoint
* *security.endpoint.password* Password for the secure endpoint

SAMOInterface has no public endpoints and therefore doesn't need to be secured.

[NOTE]
Besides the initial manual import of all addresses, this endpoints (in combination with Swagger) are primarily a convenient way to
test the functionality of the application.


=== Configuration of each service

The following services has to be configured and its parameters will be explained in the next sections:

* <<configuration-gfsBackendService>>
* <<configuration-addressImport>>
* <<configuration-mailExport>>
* Interfaces
** <<configuration-stoerungsauskunftInterface>>
** <<configuration-SAMOInterface>>
** <<configuration-SARISInterface>>

Some parameters explained in <<configuration-gfsBackendService>> below, are used in other services
as well an won't be explained again (for example <<configuration-section-rabbit_mq>>).

[#configuration-gfsBackendService]
==== Configuration of gfsBackendService (Main Backend)

(should be "Authorization")

.How to start import of addresses manually
To start the import of addresses manually you can use the endpoint of the addressImporter,
alternatively you can wait until the cron expression starts the job automatically.

. Navigate with your browser to:

----
[HOSTNAME_OF_DEPLOYMENT]:[DEPLOYMENT_PORT_OF_ADDRESSIMPORTER]/swagger-ui.html#/
----

[start=2]
. Enter the credentials you have set for the endpoints of the addressImporter. (See <<secureEndpoints>>)
. Press "adress-import-controller". You should see now the following screen:

image::swagger-ui-addressimporter.png[]

[start=3]
. Press somewhere in the "POST" row and then press "Try it out"

image::swagger-ui-addressimporter-try-out.png[]

[start=4]
. Now press the big blue "Execute" button
. The import has successfully started if you receive a status code 200

confirmation of the passphrase is not possible in this automatic process.
