Hibernate Spring: spring.jpa.hibernate.ddl-auto属性不创建生成表不起作用
Hibernate Spring: spring.jpa.hibernate.ddl-auto属性不创建生成表不起作用

我在Hibernate中使用Spring。我使用配置Java类配置Hibernate：
DbConfig.java
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "testproject", entityManagerFactoryRef = "entityManagerFactory")
public class DbConfig {
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(getDatasource());
entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
entityManagerFactoryBean.setJpaProperties(getHibernateProperties());
entityManagerFactoryBean.setPackagesToScan("testproject");
return entityManagerFactoryBean;
}
@Bean
public DataSource getDatasource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("org.postgresql.Driver");
dataSource.setUrl("jdbc:postgresql://127.0.0.1:5432/testproject");
dataSource.setUsername("postgres");
dataSource.setPassword("mypass");
return dataSource;
}
@Bean
public SessionFactory getSessionFactory() throws IOException {
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setPackagesToScan("testproject");
//getHibernateProperties method is a private method
sessionFactoryBean.setHibernateProperties(getHibernateProperties());
sessionFactoryBean.setDataSource(getDatasource());
sessionFactoryBean.afterPropertiesSet();
return sessionFactoryBean.getObject();
}
@Bean(name = "transactionManager")
public HibernateTransactionManager getTransactionManager() throws IOException {
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(getSessionFactory());
return transactionManager;
}
private static Properties getHibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
hibernateProperties.put("hibernate.show_sql", false);
hibernateProperties.put("spring.jpa.hibernate.ddl-auto", "create");
System.out.println();
// other properties
return hibernateProperties;
}
}表的自动创建是在getHibernateProperties方法中配置的：
hibernateProperties.put("spring.jpa.hibernate.ddl-auto", "create");但是，它似乎不起作用:在我部署服务器并尝试插入一个实体之后，我得到一个错误，而数据库没有表。

属性spring.jpa.hibernate.ddl-auto是org.springframework.boot.autoconfigure.orm.jpa.JpaProperties.Hibernate类型的，它来自Spring 。但是您使用的是Spring 。
使用hibernate.hbm2ddl.auto代替。
再读
- in Spring Boot Reference
这是可以工作的属性代码：
@Bean
private static Properties getHibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
hibernateProperties.put("hibernate.show_sql", true);
hibernateProperties.put( "hibernate.hbm2ddl.auto", "create-drop");
return hibernateProperties;
