#весенняя загрузка #h2 #mybatis
Вопрос:
Я использую spring boot v1.4.1.RELEASE
mybatis-spring-boot-starter v1.1.1
h2database v1.4.192
flywaydb v4.0.3
для создания веб-приложения spring boot.
вот мой файл части конфигурации yml или конфигурация источника данных:
datasource:
km:
driverClassName: org.h2.Driver
url: jdbc:h2:mem:km;MODE=MySQL;
И, когда я использую mysql для запуска моего модульного теста, каждый модульный тест был пройден. Но, когда я переключаюсь на базу данных h2database, тот же тест не был пройден.
Код ut приведен ниже:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = App.class)
@ActiveProfiles("unit-test")
@Transactional
@Rollback
public class FollowServiceTest {
private int HOST_ID = 1;
private int UID = 100;
@Autowired
private FollowService followService;
@Autowired
private UserFollowDAO followDAO;
@Test
public void testFans() throws Exception {
UserFollow userFollow = new UserFollow();
userFollow.setHostId(HOST_ID);
userFollow.setFollowerId(UID);
followDAO.insert(userFollow);
List<UserFollow> fans = followDAO.findByIndexHostId(HOST_ID, 0, 10);
assertThat("fans is empty", fans, not(empty()));
}
}
UserFollowDAO:
public interface UserFollowDAO {
public static final String COL_ALL = " id, host_id, follower_id, create_time, last_update_time ";
public static final String TABLE = " user_follow ";
@Select(" select "
COL_ALL
" from "
TABLE
" where "
"`host_id` = #{hostId} "
" and id > #{lastId} "
" limit #{count} "
)
public List<UserFollow> findByIndexHostId(
@Param("hostId") int hostId,
@Param("lastId") int lastId,
@Param("count") int count
);
@Insert(" insert into " TABLE " set "
" id = #{id}, "
" host_id = #{hostId}, "
" follower_id = #{followerId}, "
" create_time = now(), "
" last_update_time = now()")
public int insert(UserFollow bean);
}
Информация об ошибке:
java.lang.AssertionError: fans is empty
Expected: not an empty collection
but: was <[]>

Here is my solutions that I have try:
- Change datasource config in yml file from
url: jdbc:h2:mem:km;MODE=MySQL
tourl: jdbc:h2:mem:km;MODE=MySQL;LOCK_MODE=1
. Not work. - Delete
@Transactional
and@Rollback
annotation from ut code. Not work.
What can I do next to solve this problem?
@pau:
Here is part of my application-unit-test.yml
config file:
datasource:
ut: true
km:
driverClassName: org.h2.Driver
url: jdbc:h2:mem:km;MODE=MySQL
И я изменил конфигурацию источника данных, как вы сказали:
@Value("${datasource.ut}")
private boolean isUt;
public static final String SQL_SESSION_FACTORY_NAME = "sessionFactoryKm";
public static final String TX_MANAGER = "txManagerKm";
private static final Logger logger = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());
@Bean(name = "datasourceKm")
@Primary
@ConfigurationProperties(prefix = "datasource.km")
public DataSource dataSourceKm() {
if (isUt){
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
return builder.setType(EmbeddedDatabaseType.H2).build();
// Because I am use migration db to execute init sql script, so I haven't set script.
}
return DataSourceBuilder.create().build();
}
Вот flyway
компонент:
@Bean(name = "KmMigration", initMethod = "migrate")
@Primary
public Flyway flyway() throws SQLException {
logger.info(("================= start km db migration ================="));
Flyway flyway = new Flyway();
flyway.setDataSource(dataSourceKm());
flyway.setBaselineOnMigrate(true);
if (flyway.getDataSource().getConnection().getMetaData().getDatabaseProductName().toString().contains("H2")) {
logger.info(("================= using h2 database to start this app ================="));
flyway.setLocations("/db/migration/ut/km");
} else {
flyway.setLocations("/db/migration/km");
}
// different developer environment. might get different checksum,
// add the statement to skip the checksum error
// TODO: Maintain checksum across all developers environment.
flyway.setValidateOnMigrate(false);
MigrationVersion baselineVersion = flyway.getBaselineVersion();
logger.info(baselineVersion.getVersion());
return flyway;
}
Ответ №1:
В mycode есть какая-то ошибка:
@Insert(" insert into " TABLE " set "
" id = #{id}, "// this line
" host_id = #{hostId}, "
" follower_id = #{followerId}, "
" create_time = now(), "
" last_update_time = now()")
public int insert(UserFollow bean);
Этот метод insert будет использовать значение id в bean, то есть 0. Таким образом, я не могу получить правильное значение. когда я удаляю эту строку, модульный тест пройден.
