Hibernate5沒有與Spring5交易？

Question

我正在使用Hibernate5.3和Spring5.0.6。 我想在JPA中使用EntityManager ，所以這是配置：

@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，我使用Junit5對其進行測試：

@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();
    }

}

並拋出javax.persistence.TransactionRequiredException ：

誰能幫我？

Answer 1

實際上，您不需要自行設置entityManager。 您只需要編寫datasource bean，就會根據該數據源設置transactionManager（JPA），entityManager。

但是您的配置似乎正確。 問題是您如何使用EntityManager ，我認為您不應該創建它，而應該從上下文中使用它。 如果您自己創建它，則需要設置數據源，設置事務管理器，也許還有很多其他東西。

Answer 2

使用EntityManager而不是EntityManagerFactory並在其上放置@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();
    }

}
