フライウェイJDBCマイグレーション接続のトラブル

2017-12-18 6 views

私はフライウェイJDBCの移行に問題がある：すべての文を実行した後、私はconn.close();方法でDB接続をクローズしようとしていると私はorg.postgresql.util.PSQLException: This connection has been closed.例外を受け取ります。私が自分のデータベースをチェックすると、マイグレーションの中でやっていたすべての変更が行われますが、schema_versionテーブルは更新されません。マイグレーションに関する項目は追加されませんでした。
詳細：
flyway.propertiesでclasspath:com/packageone/somepackege/database/migrationをflyway.locationsセクションに追加しました。それから私は、移行を実行するクラスを作成している：public class V1_1_1__SomeImportantMigration implements JdbcMigrationをし、そのようなmigrate方法に充填：
フライウェイJDBCマイグレーション接続のトラブル

@Override 
     public void migrate(Connection conn) throws Exception { 
      beforeActions(conn); 
      veryImportantMigration(conn, getData(conn)); 
      afterActions(conn); 
      conn.close(); 
     }

migrate方法で行われている事を適用しますが、接続をクローズすると、例外につながるされています。
上記の情報のため、私はそのような質問をしています。なぜ、この接続が閉じられてしまうのですか？何によって？

あなたは部分的に行われていると言っています。欠落している例外はありますか？ログを提供できますか？ – Korgen

+2

あなたはその接続を閉じるべきではなく、それはフライウェイが所有しています。 –

+0

@Korgen、ログを共有できます。部分的にCocerning - それはちょうど私の間違いだった... –

答えて

2

あなたはフライウェイによってあなたに提供される接続にclose()を呼び出すべきではありません。 Flywayはこの接続自体を他のハウスキーピングタスク（バージョンテーブルの更新を含む）に使用し、それを閉じることで飛行機が正常に動作するのを防ぎます。
