CDI extension for HikariCP: This CDI portable extension provides support for injecting HikariCP data sources in your Helidon MicroProfile applications.

Maven Coordinates

To enable HikariCP Support add the following dependency to your project’s pom.xml (see Managing Dependencies).

<dependency>

Injecting a HikariCP data source

The following examples show how to create a DataSource named orders in your application.

Field-injection example

 @Inject
 @Named("orders")
 private DataSource ordersDataSource;

Copied

Constructor-injection example

 private final DataSource ds;
 @Inject
 public YourConstructor(@Named("orders") DataSource ds) {
   super();
   this.ds = ds;
 }

Copied

The extension implements this injection point by creating a HikariDataSource object in the application scope.

You can configure the object using MicroProfile config. For example, the data source created above can be configured as follows:

META-INF/microprofile-config.properties

javax.sql.DataSource.orders.dataSourceClassName=oracle.jdbc.pool.OracleDataSource
javax.sql.DataSource.orders.dataSource.url = jdbc:oracle:thin:@localhost:1521:ORCL
javax.sql.DataSource.orders.dataSource.user = sys as sysoper
javax.sql.DataSource.orders.dataSource.password = Oracle

Copied

Property names that start with javax.sql.DataSource.dataSourceName. are parsed, and the remaining portion of each name is treated as a Hikari connection pool property.
