我有遷飛JDBC遷移麻煩:執行我試圖關閉數據庫連接與conn.close();方法,而且所有報表後,我收到org.postgresql.util.PSQLException: This connection has been closed.例外。當我檢查數據庫時 - 我在遷移過程中所做的所有更改都已完成,但schema_version表未更新:未添加有關遷移的項目。
更多細節在這裏:
在flyway.properties我添加了classpath:com/packageone/somepackege/database/migrationflyway.locations部分。然後,我創建了將執行遷移類:public class V1_1_1__SomeImportantMigration implements JdbcMigration並填寫migrate方式類似:即在migrate方法做
遷飛JDBC連接遷移麻煩

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

事情被應用,但關閉連接導致異常。
由於上述信息,我有這樣的問題:爲什麼這個連接在被我關閉之前關閉?並通過什麼?

你說他們是部分完成的。你有沒有例外?你能提供日誌嗎? – Korgen

您不應該關閉該連接,它由飛路擁有。 –

@Korgen,我可以分享日誌。部分惹眼 - 這只是我的錯誤... –

你不應該調用由遷飛提供給您的連接上close()。 Flyway將其自身用於其他內務處理任務(包括更新版本表),並關閉它可防止飛路正常工作。
