= Connecting a Java application to a database
|
|
|
|
To connect your Java application to the database, use the `odo link` command.
|
|
|
|
.Procedure
|
|
|
|
. Display the list of services:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ odo service list
|
|
----
|
|
+
|
|
.Example output
|
|
[source,terminal]
|
|
----
|
|
NAME AGE
|
|
Database/sampledatabase 6m31s
|
|
----
|
|
|
|
. Connect the database to your application:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ odo link Database/sampledatabase
|
|
----
|
|
|
|
. Push the changes to your cluster:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ odo push
|
|
----
|
|
+
|
|
After the link has been created and pushed, a secret that contains the database connection data is created.
|
|
|
|
. Check the component for values injected from the database service:
|
|
+
|
|
[source,sh]
|
|
----
|
|
$ odo exec -- bash -c 'env | grep DATABASE'
|
|
declare -x DATABASE_CLUSTERIP="10.106.182.173"
|
|
declare -x DATABASE_DB_NAME="sampledb"
|
|
declare -x DATABASE_DB_PASSWORD="samplepwd"
|
|
declare -x DATABASE_DB_USER="sampleuser"
|
|
----
|
|
|
|
. Open the URL of your Java application and navigate to the `CreatePerson.xhtml` data entry page. Enter a username and age by using the form. Click *Save*.
|
|
+
|
|
Note that now you can see the data in the database by clicking the *View Persons Record List* link.
|
|
+
|
|
You can also use a CLI tool such as `psql` to manipulate the database.
