use of cn.taketoday.beans.factory.BeanFactory in project today-framework by TAKETODAY.

the class TestContextTransactionUtils method retrieveDataSource.

/**

 * <ol>
 * <li>Look up the {@code DataSource} by type and name, if the supplied
 * {@code name} is non-empty, throwing a {@link BeansException} if the named
 * {@code DataSource} does not exist.
 * <li>Attempt to look up the single {@code DataSource} by type.
 * <li>Attempt to look up the <em>primary</em> {@code DataSource} by type.
 * <li>Attempt to look up the {@code DataSource} by type and the
 * {@linkplain #DEFAULT_DATA_SOURCE_NAME default data source name}.
 * </ol>
 *
 * @param testContext the test context for which the {@code DataSource}
 * should be retrieved; never {@code null}
 * @param name the name of the {@code DataSource} to retrieve
 * (may be {@code null} or <em>empty</em>)
 * @return the {@code DataSource} to use, or {@code null} if not found
 * @throws BeansException if an error occurs while retrieving an explicitly
 * named {@code DataSource}
