spring-solr-dataショーケースサンプルプロジェクトの例外

Question

spring data solrショーケース（github link）でsolr検索の例を開始すると、この例外が発生します。私はsolr：6.1.0とデフォルトのコレクションgettingstartedを使用しています。ここではxmlドキュメントをsolrのexampledocsディレクトリに入れています。

Answer 1

春ブーツとのSolrのより新しいバージョンを使用してbranchを見ているとreadmeのRunning Showcase (Solr 5)セクションを確認してください。 Solr 6と同じ手順にする必要があります。
