我尝试连接到Derby内部数据库时开发了一些单元测试，但得到以下内容：

似乎数据库不是在内部数据库中创建的，或者我在这里遗漏了什么？

祝你好运

Answer 1

以下内容已被注释掉。因此，预计不会创建表和其他数据库对象（例如序列）。

<!-- <property name="eclipselink.ddl-generation" value="drop-and-create-tables" /> -->

只需删除评论即可正常使用：

<property name="eclipselink.ddl-generation" value="drop-and-create-tables" />

另外注意，在JDBC连接字符串中使用create=true不会影响这一点。它只是关于创建数据库本身，而不是创建表和其他对象。
