我想在现有数据库和JPA注释中定义的实体之间执行liquibase:diff
。
实际上,我没有使用persistence.xml来定义entityManagerFactory,而是使用Spring和基于Java的配置:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory()
{
LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
entityManagerFactory.setDataSource(dataSource());
entityManagerFactory.setPersistenceUnitName("my-persistence-unit");
entityManagerFactory.setPackagesToScan("com.mycompany.entities");
entityManagerFactory.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
Properties properties = new Properties();
properties.put("javax.persistence.transactionType", "RESOURCE_LOCAL");
properties.put("hibernate.hbm2ddl.auto", "validate");
properties.put("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
properties.put("hibernate.connection.url", "jdbc:h2:D:/work/06-database/my-database;");
properties.put("hibernate.format_sql", "true");
properties.put("hibernate.connection.username", "sa");
properties.put("hibernate.connection.password", "");
entityManagerFactory.setJpaProperties(properties);
return entityManagerFactory;
}
实体在com.mycompany.entities
中定义,我想在liquibase中引用我的持久性单元,以便它可以进行差异。

我尝试按照博文中的建议使用liquibase-hibernate
扩展程序:http://thecliftonian.wordpress.com/2012/04/05/liquibase-2-0-3-with-hibernate-3-5-6-and-annotations/
通过更新referenceUrl:<referenceUrl>persistance:my-persistance-unit</referenceUrl>
但我有这个例外:
Error setting up or running Liquibase: liquibase.exception.DatabaseException: Connection could not be created to src/main/resources/META-INF/persistence.xml with driver org.h
2.Driver. Possibly the wrong driver for the given database URL
所以我的问题是如何在Liquibase中引用持久性单元名称?
有没有更好的方法来实现这一目标?
更新:referenceURl的javadoc说:
The reference database URL to connect to for executing Liquibase. If performing a diff against a Hibernate config xml file, then use <b>"hibernate:PATH_TO_CONFIG_XML"</b> as the URL. The path to the hibernate configuration file can be relative to the test classpath for the Maven project."
答案 0 :(得分:1)
你引用的blob帖子看起来好像需要修补版本的集成,但是当他们的pull请求被带入liquibase-hibernate代码库时,我不相信它已成为一个发布,所以你需要自己做一个自定义的插件版本。
