データベースのテーブルから最初の10行を取得する簡単なHQLクエリを作成しました。私はオブジェクトのリストからデータを印刷することができます。Java/Hibernate HQLがヌルエラーを返すテーブルクエリからローを取得する
このコードは、＃{HomeController.results}というHTMLで呼び出されます。その後、ログリストはHome Controllerクラスに戻されます。私が試してみて、私は簡単なことだろうと思った他のクエリを実行するたびに
String queryString = "FROM Log";
Query query = entity.createQuery(queryString);
query.setMaxResults(10);
List<Log> results = query.getResultList();
は残念ながら、それはフリークアウトし、nullポインタまたは境界エラーの外をスローします。
たとえば、しようとする代わりに、最後の10行を取得するには、リストの順序を変更：HTMLは、最初のプロパティを（すべての行がbatchIdを持っている）にアクセスしようとしたとき
String queryString = "FROM Log ORDER BY batchId DESC";
はnullポインタエラーを与えます。
か試してみて、今週から行を取得するには：
String queryString = "FROM Log x WHERE to_char(x.logDate, 'WW/YYYY') =
to_char(current_date, 'WW/YYYY')";
があまりにも最初のプロパティの境界の外のインデックスを与えます。私は間違って簡単なことをしているに違いないと思います。 REQUEST UPON
EDIT：
HTML：
<!-- get table from database, returns size of results list -->
Results: <h:outputText value="#{homeController.results}" />
<br></br>
BatchId: <h:outputText value="#{homeController.batchId}" />
