在休眠之前运行SpringLiquibase

Question

我正在使用SpringLiquibase在应用程序启动期间自动应用我的liquibase更新.一般来说这很好用,但是当我将hibernate.hbm2ddl.auto设置为"validate"时,在liquibase似乎有机会应用更新之前,hibernate开始抱怨数据库方案.我的配置如下所示:

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = "com.myapp")
@PropertySource(value = {"classpath:myapp.properties"})
@EnableJpaRepositories("com.myapp")
public class MyappConfig {

    @Resource
    private Environment env;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(env.getRequiredProperty("jdbc.driver"));
        dataSource.setUrl(env.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(env.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(env.getRequiredProperty("jdbc.password"));

        return dataSource;
    }

    @Bean
    public SpringLiquibase liquibase() {
        SpringLiquibase liquibase = new SpringLiquibase();
        liquibase.setDataSource(dataSource());
        liquibase.setChangeLog("classpath:liquibase/liquibase-master-changelog.xml");
        return liquibase;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
        entityManagerFactoryBean.setPackagesToScan("com.myapp");

        entityManagerFactoryBean.setJpaProperties(hibernateProperties());

        return entityManagerFactoryBean;
    }

    private Properties hibernateProperties() {
        Properties properties = new Properties();

        String[] propertyNames = new String[]{"hibernate.dialect", "hibernate.show_sql", "hibernate.hbm2ddl.auto"};

        for (String propertyName : propertyNames) {
            properties.put(propertyName, env.getRequiredProperty(propertyName));
        }
        return properties;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
        return transactionManager;
    }

}

在hibernate尝试验证模式之前,有没有办法让liquibase应用它的更新？

感谢 M. Deinum,我能够通过使用来解决这个问题

@Bean
@DependsOn("liquibase")
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
   [...]
}

在@DependsOn确保了liquibase是Hibernate的架构验证之前运行.
