Spring - Spring 5.2.0.RELEASE 中的单元测试存储库

Question

我有这门课：

@Configuration
@EnableJpaRepositories(basePackages = "es.calero.repositories")
public class TestConfig {

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.h2.Driver");
        dataSource.setUrl("jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1");
        dataSource.setUsername("sa");
        dataSource.setPassword("");
        return dataSource;
    }



    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(dataSource);
        em.setPackagesToScan("es.calero.model.inscriptions");
        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        return em;
    }
}

还有这个：

@ContextConfiguration(classes = es.calero.repositories.utils.TestConfig.class)
@Transactional
public class AutorisationSortieRepositoryTest {

    @Autowired
    private AutorisationSortieRepository autorisationSortieRepository;

    private es.calero.model.autorisation.AutorisationSortie autorisationSortie;

    @Before
    public void setUp() {

        // Insert test data into the in-memory database
        autorisationSortie = new AutorisationSortie();
        autorisationSortie.setEnfantId(1L);
        autorisationSortie.setDtDebut(new Date());
        autorisationSortie.setDtFin(new Date(System.currentTimeMillis() + 86400000L)); // +1 day

        autorisationSortieRepository.save(autorisationSortie);
    }

    @Test
    public void testFindActiveAutorisationSortieByEnfantId() {
        // Create a reference date within the range
        Date dtRef = new Date(System.currentTimeMillis() + 43200000L); // +12 hours

        List<AutorisationSortie> result = autorisationSortieRepository.findActiveAutorisationSortieByEnfantId(1L, dtRef);

        // Assert the result is not empty and contains the expected AutorisationSortie
        Assert.assertTrue("Result should not be empty", !result.isEmpty());
        assertEquals("Result should contain the test AutorisationSortie", autorisationSortie, result.get(0));
    }

    @Test
    public void testFindActiveAutorisationSortieByEnfantId_NoResult() {
        // Create a reference date outside the range
        Date dtRef = new Date(System.currentTimeMillis() - 86400000L); // -1 day

        List<AutorisationSortie> result = autorisationSortieRepository.findActiveAutorisationSortieByEnfantId(1L, dtRef);

        // Assert that no results are found
        Assert.assertTrue("Result should be empty", result.isEmpty());
    }

}

但是我有一个空指针

autorisationSortieRepository.save(autorisationSortie);:

添加

@RunWith(SpringJUnit4ClassRunner.class)

时出现此错误：

   initializationError(es.calero.repositories.autorisation.AutorisationSortieRepositoryTest)  Time elapsed: 0.011 sec  <<< ERROR!

Answer 1

首先，你必须在

@RunWith(SpringJUnit4ClassRunner.class)

类上添加

AutorisationSortieRepositoryTest

才能使bean的注入起作用。

其次，请使用

spring-data-jpa

版本

2.2.0.RELEASE

，它使用Spring依赖项的

5.2.0.RELEASE

。

更新

pom.xml

中的 spring-data-jpa 依赖项：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>2.2.0.RELEASE</version>
</dependency>

看看这是否有帮助。
