How to set some Hibernate properties in Spring JPA Web Application?

Question

I am trying to get rid of the typical persistence.xml file in Spring JPA web application. So far, I have managed to inject the EntityManager successful

Answer 1

Spring provides a way to configure these options in provider-independent way using AbstractJpaVendorAdapter (setDatabase() and setGenerateDdl(), though setGenerateDdl() doesn't take DDL mode).

Alternatively, you can pass arbitrary properties to LocalContainerEntityManagerFactory using setJpaProperties() (or setJpaPropertyMap()):

Properties props = new Properties();
props.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
props.put("hibernate.hbm2ddl.auto", "create");
factoryBean.setJpaProperties(props);
