Java Spring测试失败，出现NoClassDefFoundError

我有一个配置类

@Configuration
@EnableTransactionManagement
@EnableSpringDataWebSupport
public class WebConfig {

    @Bean
    public RequestContextListener requestContextListener() {
        return new RequestContextListener();
    }

    @Bean
    public DataSource dataSource() {

        EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
        return builder.setType(EmbeddedDatabaseType.H2).build();
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);
        vendorAdapter.setShowSql(true);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("mypackage");
        factory.setDataSource(dataSource());
        factory.afterPropertiesSet();

        return factory.getObject();
    }

}

我有一个测试班

@RunWith(SpringRunner.class)
@SpringBootTest(classes = App.class)
public class UserServiceTest {


    @Autowired
    private MyRepository myRepository;


    @Before
    public void initDB(){

        MyObj my = new MyObj();
        my.setValue(1000L);

        myRepository.save(my);
    }

    @Test
    public void test1() {
        assertEquals(4, userMoneyRepository.findAll());
    }

}

我的错误是

在config.WebConfig.entityManagerFactoryWebConfig.java:48中，我有factory.afterPropertieSet； 我该怎么办？当我用SpringBoot启动应用程序时，我使用了这个配置，它可以正常工作。

当我的应用程序工作时，我有运行时数据库。我想将此配置用于测试。

如果使用Gradle，请添加以下内容：

compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.0'

如果使用Maven，请添加以下内容：

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

您使用的是哪个JDK版本？哪个Spring引导版本？
