java初始化数据报

我正在使用AbstractRoutingDatasource在运行时在数据库之间进行路由.在informix数据库的实际情况下一切正常.

对于测试,我创建了一个弹簧配置文件,用于内存H2数据库.

运行测试配置文件后的spring应用程序后,我使用h2控制台检查了本地数据库.没有创建架构.

我尝试在recources和hibernates中使用schema.sql：

generate-ddl: true

hibernate:

ddl-auto: create-drop

冬眠投掷

java.lang.IllegalStateException: Cannot determine target DataSource for lookup key [null]

据我所知,hibernate试图只生成“路由”数据源.由于没有设置DatabaseContextHolder(null),因此失败.

两种方式都失败了.

有没有办法用(相同)模式初始化所有数据库？

我在下面列出了我的配置.
