私は、データを取り込もうとしている4つのテーブルのそれぞれについて、この問題以外にこの問題を明確にする方法はよくわかりません。ただ空です。どのものが空になるのか予測できません。それは、1と2、またはわずか3、または1つのテーブル以外のすべてである可能性があります。テーブルの1つが実装されていない場合、私はrollback（）catchブロックで終わります。時々彼らはすべて働きます。これはある種のスレッド中断と関係しています。下のコードと例外を考えれば、何がうまくいかないでしょうか？オブジェクトの作成と保存のためのスレッド "Thread-10"の例外java.lang.IllegalStateException
