/**
 * Specify the JDBC DataSourceLookup that provides DataSources for the
 * persistence provider, resolving data source names in {@code persistence.xml}
 * against Spring-managed DataSource instances.
 * <p>Default is JndiDataSourceLookup, which resolves DataSource names as

 * instance if you want DataSource names to be resolved against Spring bean names.
 * <p>Alternatively, consider passing in a map from names to DataSource instances
 * via the "dataSources" property. If the {@code persistence.xml} file
 * does not define DataSource names at all, specify a default DataSource
