Example User Storage Provider with EJB and JPA
|
||||
===================================================
|
||||
|
||||
This is an example of the User Storage SPI implemented using EJB and JPA. To deploy this provider you must have Keycloak
|
||||
running in standalone or standalone-ha mode. Then type the follow maven command:
|
||||
This is an example of the User Storage SPI implemented using EJB and JPA. You must first deploy the datasource it uses.
|
||||
Start up the Keycloak server. Then in the directory of this example type the following maven command:
|
||||
|
||||
mvn -Padd-datasource install
|
||||
|
||||
You only need to execute this maven command once. If you execute this again, then you will get an error message that the datasource
|
||||
already exists.
|
||||
|
||||
If you open the pom.xml file you'll see that the add-datasource profile creates an XA datasource using the built
|
||||
in H2 database that comes with the server. An XA datasource is required because you cannot use two non-xa datasources
|
||||
in the same transaction. The Keycloak database is non-xa.
|
||||
|
||||
Another thing to note is that the xa-datasource created is in-memory only. If you reboot the server, any users you've
|
||||
added or changes you've made to users loaded by this provider will be wiped clean.
|
||||
|
||||
To deploy the provider, run the following maven command:
|
||||
|
||||
mvn clean install wildfly:deploy
|
||||
|
||||
You can run as many times as you want and the provider will be redeployed.
|
||||
|
||||
Login and go to the User Federation tab and you should now see your deployed provider in the add-provider list box.
|
||||
Add the provider, save it, then any new user you create will be stored and in the custom store you implemented. You
|
||||
can modify the example and hot deploy it using the above maven command again.
|
||||
|
||||
This example uses the built in in-memory datasource that comes with keycloak: ExampleDS. NOTE!!! You'll have
|
||||
to change this to be an xa datasource for this to work.
