Question

在openshift上部署应用程序时，我有下一个问题。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:

我使用hibernate作为JPA（hibernate-core-4.3.6）。我认为这个问题与Postgresql 9.2和9.3的不同版本有谁能解释我如何在9.2 Postgres版本上更改hibernate方言或者在openshift上更改postgresql库模块？

Answer 1

我只是更改hibernate属性hibernate.hbm2ddl.auto来创建值。这解决了我的问题。

Answer 2

最近有同样的错误。请打开wildfly的standalone.xml（或standalone-full.xml或您使用的任何一个），找到并删除以下片段：

<default-bindings contextservice="java:jboss/ee/concurrency/context/default" datasource="java:jboss/datasources/ExampleDS" jms-connection factory="java:jboss/DefaultJMSConnectionFactory" managed-executor-service="java:jboss/ee/concurrency/executor/default" managed-scheduled-executor-service="java:jboss/ee/concurrency/scheduler/default" managed-thread-factory="java:jboss/ee/concurrency/factory/default"/>

重要提示：确保在编辑之前关闭wildfly，否则它将在下次关闭时覆盖更改。

Answer 3

你需要这个属性 spring.jpa.database平台= org.hibernate.dialect.H2Dialect

Answer 4

1）检查您是否在application.properties中使用了正确的方言

spring.jpa.database-platform

2）并检查spring.jpa.hibernate.ddl-auto

的值

Answer 5

spring.jpa.database-platform解决了我的问题

无法完成架构更新：org.h2.jdbc.JdbcSQLException：表＆＃34; PG_CLASS＆＃34;未找到; SQL语句
