java - 无法完成架构更新 : org. h2.jdbc.JdbcSQLException:未找到表 "PG_CLASS"； SQL语句

Question

我在 openshift 上部署应用程序时遇到下一个问题。我使用 wildfly 应用程序服务器和 PostgreSQL cartrige。

在 persistence.xml 中，我设置了属性“hibernate.hbm2ddl.auto”value="update"。在 org/main/postgresql 的 wildfly 模块中，我看到 wildfly 使用 postgresql-9.3-1102-jdbc41.jar

12:12:14,760 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (ServerService Thread Pool -- 62) HHH000319: Could not get database metadata: org.h2.jdbc.JdbcSQLException: Table "PG_CLASS" not found; SQL statement:

我将 hibernate 用作 JPA (hibernate-core-4.3.6)。而且我认为这个问题与不同版本的 Postgresql 9.2 和 9.3 谁能解释我如何在 9.2 Postgres 版本上更改 hibernate 方言或在 openshift 上更改 postgresql 库模块？

Answer 1

我刚刚将 hibernate 属性 hibernate.hbm2ddl.auto 更改为 create。这为我解决了这个问题。
