Hibernate使用JPA（注释实体）和liquibase [英] Hibernate using JPA (annotated Entities) and liquibase

问题描述

liquibase是hibernate的 hbm2ddl_auto 属性的完美替代方案如果您使用xml映射。但我使用JPA注释（休眠注释）。是否可以使用liquibase呢？

解决方案

Liquibase使用hibernate的元数据类，无论使用xml映射或注释。你需要一个休眠配置文件来指向liquibase，但你的映射可以是xml或jpa注释。更多信息请参见 https://github.com/liquibase/liquibase-hibernate/wiki，但可以使用数据库URL，例如

  hibernate：classic：com / example / hibernate.cfg.xml 
  

如果您有hibernate xml conf文件或

  hibernate：ejb3：myPersistenceUnit 
  

如果您有META -INF / persistence.xml，或者

  hibernate：spring：com.example？dialect = org.hibernate.dialect.MySQL5Dialect 
  

如果您想根据包含注释实体的java包自动生成JPA配置。

liquibase is a perfect alternative to hibernate's hbm2ddl_auto property if you are using xml-mapping. But Im using JPA annotation (hibernate annotations). Is it possible to use liquibase then?

解决方案

Yes, Liquibase uses hibernate's metadata classes, which are the same whether you use xml mappings or annotations. You do need a hibernate config file to point liquibase to, but your mappings can be xml or jpa annotations. More information can be found at https://github.com/liquibase/liquibase-hibernate/wiki but you can use "database urls" such as

hibernate:classic:com/example/hibernate.cfg.xml

if you have a hibernate xml conf file or

hibernate:ejb3:myPersistenceUnit

if you have a META-INF/persistence.xml, or

hibernate:spring:com.example?dialect=org.hibernate.dialect.MySQL5Dialect

if you would like auto-generate a JPA configuration based on a java package containing annotated Entities.
