我发现实际上是Spring,我可以设置一些工作.现在,我想使用Hibernate/JPA将我导入的数据保存在数据库中,并且我不断收到此错误:
14:46:43.500 [main] ERROR o.s.b.core.step.AbstractStep - Encountered an error executing the step javax.persistence.TransactionRequiredException: no transaction is in progress
我看到问题出在交易上.这是我的spring java配置entityManager和transactionManager:
@Configuration
public class PersistenceSpringConfig implements EnvironmentAware
{
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws Exception
{
// Initializes the entity manager
LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
factoryBean.setPersistenceUnitName(PERSISTENCE_UNIT_NAME);
factoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
factoryBean.setDataSource(dataSource());
// Scans the database model
factoryBean.setPackagesToScan(EntiteJuridiqueJPA.class.getPackage().getName());
// Defines the Hibernate properties
Properties jpaProperties = new Properties();
jpaProperties.setProperty("hibernate.show_sql", "false");
jpaProperties.setProperty("hibernate.format_sql", "false");
String connectionURL = "jdbc:h2:file:" + getDatabaseLocation();
jpaProperties.setProperty("hibernate.connection.url", connectionURL); …当我尝试在 spring 批处理中使用我的作业处理器将我从 csv 文件恢复的一些数据保留在数据库中时，此错误出现在控制台中，对于我的 dao，我正在使用 hibernate
我已经尝试了 2 种方法但同样的问题！
第一的 ：
Session session = factory.getCurrentSession();
session.saveOrUpdate(p);
第二 ：
Session session = factory.openSession();
session.beginTransaction();
session.save(p);
session.getTransaction().commit();
session.close();
