### 7.2. Using DataSources

<div class="paragraph">

Hibernate can integrate with a `javax.sql.DataSource` for obtaining JDBC Connections.
Applications would tell Hibernate about the `DataSource` via the (required) `hibernate.connection.datasource` setting which can either specify a JNDI name or would reference the actual `DataSource` instance.
For cases where a JNDI name is given, be sure to read [JNDI](#jndi)

<div class="admonitionblock note">
<table>
<tr>
<td class="icon">

</td>
<td class="content">
<div class="paragraph">

For JPA applications, note that `hibernate.connection.datasource` corresponds to either `javax.persistence.jtaDataSource` or `javax.persistence.nonJtaDataSource`.

</div>
</td>
</tr>
</table>
</div>
<div class="paragraph">

The `DataSource` `ConnectionProvider` also (optionally) accepts the `hibernate.connection.username` and `hibernate.connection.password`.
If specified, the [`DataSource#getConnection(String username, String password)`](https://docs.oracle.com/javase/8/docs/api/javax/sql/DataSource.html#getConnection-java.lang.String-java.lang.String-) will be used.
Otherwise, the no-arg form is used.
