java h2内存数据库错误：找不到表

我试过谷歌搜索,但几乎所有这类问题的解决方案是添加; DB_CLOSE_DELAY = -1,但它并没有为我解决任何问题.

这是我的测试课

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {Main.class})
public class Testas {

    @Autowired
    @Qualifier("managerImplementation")
    private ClassifierManager manager;

    @Test
    public void testManager(){
        ClassifierGroupEntity cge = new ClassifierGroupEntity();
        manager.saveClassifierGroup(cge);
    }
}

经理班

@Service("managerImplementation")
public class ClassifierManagerImpl implements ClassifierManager{

    @Autowired
    private ClassifierGroupEntityRepository groupEntityRepository;

    @Autowired
    private ClassifierEntityRepository entityRepository;

    @Autowired 
    private ClassifierValueEntityRepository valueEntityRepository;

    @Override
    public ClassifierGroupEntity getClassifierGroup(long id) {
        return groupEntityRepository.findOne(id);
    }

    @Override
    public ClassifierGroupEntity getClassifierGroup(String code) {
        return groupEntityRepository.findByCode(code);
    }

    @Override
    public ClassifierGroupEntity saveClassifierGroup(ClassifierGroupEntity entity) {
        return groupEntityRepository.save(entity);
    }

    @Override
    public void deleteClassifierGroup(long id) {
        groupEntityRepository.delete(id);
    }

    @Override
    public ClassifierEntity getClassifier(long id) {
        return entityRepository.findOne(id);
    }

    @Override
    public ClassifierEntity getClassifier(String code) {
        return entityRepository.findByCode(code);
    }

    @Override
    public ClassifierEntity saveClassifier(ClassifierEntity entity) {
        return entityRepository.save(entity);
    }

    @Override
    public void deleteClassifier(long id) {
        entityRepository.delete(id);
    }

    @Override
    public ClassifierValueEntity getClassifierValue(long id) {
        return valueEntityRepository.findOne(id);
    }

    @Override
    public ClassifierValue getClassifierValue(String classifiedCode,String valueCode) {
        return null;
    }

    @Override
    public ClassifierValueEntity saveClassifierValue(ClassifierValueEntity entity) {
        return valueEntityRepository.save(entity);
    }

    @Override
    public void deleteClassifierValue(long id) {
        valueEntityRepository.delete(id);
    }


}

最后是属性文件

spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.user=sa
spring.datasource.password=
spring.datasource.url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1

启动测试会让我失望

org.h2.jdbc.JdbcSQLException: Table "CLASSIFIER_GROUP_ENTITY" not found; SQL statement:
insert into classifier_group_entity (id,code,modified_details,modified_time,modified_user_id,order,revision,valid_details,valid_from,valid_till,parent_id) values (null,?,?) [42102-191]

我不知道是否应该提供其他任何东西,如果我这样做,请告诉我.我提前感谢您的帮助.
