测试hibernate存储库时，Spring Boot不处理junit中的提交

Question

嗨，我正在尝试构建一个 junit 测试用例@before setup，但在处理 junit 类之后，我发现我的数据库中没有数据更改，也没有抛出异常。有趣的是我可以从控制器调用，它可以通过从 http 客户端调用服务来保存和删除。下面是我的代码，请帮忙。非常感谢。

@SpringApplicationConfiguration(classes = MockServletContext.class)
@WebAppConfiguration
public class UserRepositoryTest extends AbstractBestFirstTest {

    private MockMvc mvc;

    @Autowired
    private UserRepositoryI userRepo;

    private void userRepositoryTestPreparer() {
        User user = new User();
        user.setEmail("markII@gmail.com");
        user.setName("Tony Stark");
        userRepo.deleteAll();
        userRepo.save(user);
    }

    @BeforeTransaction
    public void setUpData() {
        userRepositoryTestPreparer();
    }

    @Before
    public void setUp() {
        mvc = MockMvcBuilders.standaloneSetup(new SampleController()).build();
    }

    @After
    public void tearDown() {
        // implement me
    }

    @Transactional
    @Commit
    @Test
    public void testSave() {
        Assert.assertEquals("save failed", 1, userRepo.findUserByName("Tony Stark").size());
        Assert.assertEquals("save failed", 1, userRepo.findUserByEmail("markII@gmail.com").size());
    }

    @Test
    public void testRestfulBasic() throws Exception {
        ResultActions actions = mvc.perform(MockMvcRequestBuilders.get("/sample").accept(MediaType.APPLICATION_JSON));
        actions.andExpect(status().isOk());
        actions.andExpect(content().string(equalTo("Hello World! Greetings from spring boot")));
    }

}

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = BestfirstApplication.class)
public abstract class AbstractBestFirstTest {
    protected Logger logger = LoggerFactory.getLogger(this.getClass());

}

@Transactional
public interface UserRepositoryI extends CrudRepository<User, Long>,UserRepositoryCustomerizedI  {


}

我最终解决了这个问题。在 Spring 测试场景中，我们必须使用 PlatformTransactionManager 来处理事务。事实上，我错过了数据库配置中的这一部分。添加到我的配置后，问题就消失了！

@Configuration
@EnableTransactionManagement
public class DatabaseConfig {

    @Value("${db.driver}")
    private String DB_DRIVER;

    @Value("${db.password}")
    private String DB_PASSWORD;

    @Value("${db.url}")
    private String DB_URL;

    @Value("${db.username}")
    private String DB_USERNAME;

    @Value("${hibernate.dialect}")
    private String HIBERNATE_DIALECT;

    @Value("${hibernate.show_sql}")
    private String HIBERNATE_SHOW_SQL;

    @Value("${hibernate.hbm2ddl.auto}")
    private String HIBERNATE_HBM2DDL_AUTO;

    @Value("${entitymanager.packagesToScan}")
    private String ENTITYMANAGER_PACKAGES_TO_SCAN;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(DB_DRIVER);
        dataSource.setUrl(DB_URL);
        dataSource.setUsername(DB_USERNAME);
        dataSource.setPassword(DB_PASSWORD);
        return dataSource;
    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource());
        sessionFactoryBean.setPackagesToScan(ENTITYMANAGER_PACKAGES_TO_SCAN);
        Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.dialect", HIBERNATE_DIALECT);
        hibernateProperties.put("hibernate.show_sql", HIBERNATE_SHOW_SQL);
        hibernateProperties.put("hibernate.hbm2ddl.auto", HIBERNATE_HBM2DDL_AUTO);
        sessionFactoryBean.setHibernateProperties(hibernateProperties);

        return sessionFactoryBean;
    }

    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());
        return transactionManager;
    }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);
        return transactionManager;
    }
}

您还可以使用Rollback(false) 注释测试，请参阅Persist/commit not working in test environment with Spring JPA JUnit
