我使用的是Hibernate5.3和Spring5.0.6。我想在JPA中使用EntityManager
所以这是配置:
@Configuration
@EnableTransactionManagement
public class HibernateConfig {
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
entityManager.setDataSource(dataSource());
entityManager.setPackagesToScan("com.geniusver.model");
entityManager.setJpaProperties(getHibernateProperties());
HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
hibernateJpaVendorAdapter.setShowSql(true);
hibernateJpaVendorAdapter.setDatabase(Database.MYSQL);
entityManager.setJpaVendorAdapter(hibernateJpaVendorAdapter);
return entityManager;
}
@Bean
public DataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUsername("root");
dataSource.setPassword("123456");
dataSource.setUrl("jdbc:mysql://localhost:3306/test?useSSL=false");
return dataSource;
}
@Bean
public JpaTransactionManager transactionManager(@Autowired EntityManagerFactory entityManagerFactory) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory);
return transactionManager;
}
private final Properties getHibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.hbm2ddl.auto", "update");
hibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL57Dialect");
return hibernateProperties;
}
}
然后我用Junit5测试它:
@Transactional
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = Application.class)
class UserTest {
@Autowired
private EntityManagerFactory entityManagerFactory;
private EntityManager entityManager;
@BeforeAll
void beforeAll() {
entityManager = entityManagerFactory.createEntityManager();
assertNotNull(entityManager);
assertNotNull(entityManagerFactory);
}
@Rollback(value = false)
@Test
void persist() {
User user = new User("testName", "password");
entityManager.persist(user);
entityManager.flush();
}
}
它抛出javax.persistence.TransactionRequiredException

任何人都可以帮助我吗?

实际上你不需要将entityManager设置为你自己。您只需要编写--exec babel-node
bean和transactionManager(JPA),entityManager将根据该数据源进行设置。
但您的配置似乎正确。问题是你如何使用datasource
,我认为你不应该创建它,你应该从上下文中使用它。如果您自己创建它,则需要设置数据源,设置事务管理器以及许多其他事项。

使用EntityManager
代替EntityManagerFactory
并在其上加@PresistenceContext
。
@Transactional
@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = Application.class)
class UserTest {
@PersistenceContext
private EntityManager entityManager;
@Rollback(value = false)
@Test
void persist() {
User user = new User(2L, "testName", "password");
entityManager.persist(user);
entityManager.flush();
}
}
