當啓動一個嵌入的HSQLDB有時記錄例外：檢測HSQLDB初始化失敗是由於腐敗

好像HSQLDB吞下這些異常。
這會導致我們的java代碼繼續運行，即使數據庫可能已損壞。
有沒有辦法來捕捉這些異常？
或者Java API調用來驗證數據庫是否正確啓動？
你可以發佈你的代碼在哪裏訪問數據庫？ – developer
由於存在持久性問題，2.2.7版本很快被替換爲2.2.8。如果不是最新版本，至少要切換到該版本。 – fredt
@javaguy我們不是晚上查詢數據庫呢。當HSQLDB被初始化時會發生這種情況。通過Hikari初始化HSQLDB： 'hikariConnPool.setDriverClassName（org.hsqldb.jdbcDriver.class.getName（））; hikariConnPool.setJdbcUrl（「jdbc：hsqldb：」+ Configuration.databasePath）;' – pietervi
