Question

我正在尝试将Firebird嵌入式数据库与Hibernate一起使用，但在尝试创建数据库时出现以下错误：

Caused by: org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544344. I/O error during "CreateFile (open)" operation for file "D:\DB\FIREBIRD.FDB"

到目前为止我做了什么：

我已经设置了休眠配置 Driver =“org.firebirdsql.jdbc.FBDriver”，
Dialect =“org.hibernate.dialect.FirebirdDialect”，
Url =“jdbc：firebirdsql：embedded：D：\ DB \ FIREBIRD.FDB”，
我已将 jaybird-full jar添加到我的类路径中。
我已将 jaybird22.dll ， fbembed.dll （整个文件夹）添加到我的路径中。

dll似乎被加载，因为如果我删除了我得到的dll并且异常告诉我 jaybird22.dll 找不到。

知道可能出现什么问题吗？

似乎我缺少的一步是手动创建数据库文件：

FBManager manager = new FBManager(GDSType.getType("EMBEDDED"));
manager.start();
manager.createDatabase(myDbFile, username, password);
manager.stop();
