我正在使用带有JPA的Spring 3。 JPA供应商是Hibernate。
当尝试持久化数据时，我想将实体提交到数据库，并将autocommit设置为true。我不想使用这些交易。
我有以下代码示例：
@Configuration
public class EntityManagerFactoryConfig {
@Autowired
private HibernateConfig hibernateConfig;
@Autowired
private DataSourceConfig dataSourceConfig;
public EntityManagerFactoryConfig() {
}
private Properties getDefaultJpaProperties() {
Properties jpaProperties = new Properties();
jpaProperties.setProperty("hibernate.show_sql", hibernateConfig.getHibernateShowSQL());
jpaProperties.setProperty("hibernate.dialect", hibernateConfig.getHibernateDialect());
jpaProperties.setProperty("hibernate.hbm2ddl.auto", hibernateConfig.getHibernateHbm2DDL());
jpaProperties.setProperty("hibernate.connection.autocommit", "true");
jpaProperties.setProperty("javax.persistence.jdbc.driver", dataSourceConfig.getJdbcDriverClassName());
jpaProperties.setProperty("javax.persistence.jdbc.user", dataSourceConfig.getJdbcUsername());
jpaProperties.setProperty("javax.persistence.jdbc.password", dataSourceConfig.getJdbcPassword());
return jpaProperties;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws Exception {
LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
localContainerEntityManagerFactoryBean.setDataSource(dataSourceConfig.dataSource());
localContainerEntityManagerFactoryBean.setJpaVendorAdapter(hibernateConfig.jpaVendorAdapter());
Properties jpaProperties = getDefaultJpaProperties();
jpaProperties.setProperty("javax.persistence.jdbc.url", dataSourceConfig.getJdbcUrlDefault());
localContainerEntityManagerFactoryBean.setJpaProperties(jpaProperties);
localContainerEntityManagerFactoryBean.setPersistenceUnitName("defaultpersistenceunit");
return localContainerEntityManagerFactoryBean;
}
当将hibernate.connection.autocommit设置为true时，Spring会抛出以下异常：

我不想使用@Transactional。我只是想在不使用事务的情况下提交数据。
我似乎无法在互联网上找到任何东西。
这怎么可能？
