我目前正在使用springboot API,已确定我和我的同事将在开发期间使用H2嵌入式数据库。
启动应用程序后,数据库可以正常运行,但是在单元测试期间我无法使其正常工作:它们都失败了org.h2.jdbc.JdbcSQLException: Table '[...]' not found
。
我基本上没有编写大部分代码,如果需要更多内容,请告诉我:
application.properties
文件,用于初始化H2数据库:
datasources.member-request.url=jdbc:h2:mem:db;IGNORECASE=TRUE;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS DMDEOWNER\\;SET SCHEMA DMDEOWNER\\;runscript from 'classpath:h2_init_script.sql'
datasources.member-request.username=sa
datasources.member-request.password=
datasources.member-request.driver-class-name=org.h2.Driver
datasources.member-request.initialize=true
如您在上面看到的,我们在H2的初始化处执行一个名为h2_init_script.sql
的SQL脚本,在此文件中,我们有一些这样的SQL语句(例如,我将向您显示T_THEME表)>
/* CREATE statements */
CREATE TABLE DMDEOWNER.T_THEME (
F_NUM_THEME NUMBER(14) NOT NULL,
F_REF_THEME VARCHAR2(30) NOT NULL,
F_LIB_THEME VARCHAR2(50) NOT NULL,
F_POS_THEME NUMBER(4) NOT NULL,
F_BOOL_ACTIF NUMBER(1) NOT NULL,
F_UTILISATEUR_MAJ VARCHAR2(40) NOT NULL,
F_DT_CREATION DATE NOT NULL,
F_DT_MAJ DATE,
PRIMARY KEY (F_NUM_THEME)
);
/* INSERT statements */
/* ... */
这是我的测试课程(及其父级):
public class ThemeRepositoryTest extends AbstractRepositoryTest {
private final static int NB_ACTIVE_ENTITIES = 2;
private final static int NB_INACTIVE_ENTITIES = 1;
@Autowired
private ThemeRepository repository;
@Autowired
private ThemeMapper mapper;
// -------------------------------------------------------------------------
// CREATE
// -------------------------------------------------------------------------
@Before
public void init() {
for (int i = INTEGER_ZERO; i < NB_ACTIVE_ENTITIES; i++) {
insertTheme(true);
}
for (int i = INTEGER_ZERO; i < NB_INACTIVE_ENTITIES; i++) {
insertTheme(false);
}
entityManager.flush();
}
// -------------------------------------------------------------------------
// READ
// -------------------------------------------------------------------------
@Test
public void findAll() {
List<ThemeEntity> list = repository.findAll();
assertEquals(NB_ACTIVE_ENTITIES + NB_INACTIVE_ENTITIES, list.size());
}
}
@RunWith(SpringRunner.class)
@DataJpaTest
public abstract class AbstractRepositoryTest {
@Autowired
protected TestEntityManager entityManager;
protected ThemeEntity insertTheme(boolean active) {
ThemeEntity entity = newThemeEntity(3L, "NAME", active, "USER");
return entityManager.merge(entity);
}
}
这是我发生错误的地方,当我调用init()
时,在insertTheme()
函数中:
findAll(io.lacipav.repository.ThemeRepositoryTest) Time elapsed: 0.227 s <<< ERROR!

[42102-197]
at io.lacipav.repository.ThemeRepositoryTest.init(ThemeRepositoryTest.java:38)
由于错误告诉我它找不到我的表,所以我猜测是因为在构建.war
文件时我的数据库未运行,如果可以的话如何初始化它更快?
编辑: 根据要求,这是T_THEME的Entity类:
@Entity
@Getter
@Setter
@Table(name = "T_THEME")
public class ThemeEntity {
/** Primary key of the table. */
@Id
@NotNull
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "theme_generator")
@SequenceGenerator(name = "theme_generator", sequenceName = "SEQ_NUM_THEME", allocationSize = 1)
@Column(name = "f_num_theme")
private Long idTechnique;
/** Theme functional identifier */
@NotNull
@Column(name = "f_ref_theme")
private String reference;
/** Theme simple short length label */
@NotNull
@Column(name = "f_lib_theme")
private String name;
//...
}
注意:将生成SQL序列“ SEQ_NUM_THEME”,并将其与SQL脚本中的F_NUM_THEME关联。
编辑2:
正如Lesiak所指出的那样,我的错误可能是由于我的数据源被注解@DataJpaTest
所代替。通过仔细查看日志,我发现了一些有趣的行。

我们可以在最后一行看到我的网址连接jdbc:h2:mem:db
已被jdbc:h2:mem:4ef27020-c472-4be9-a9af-73f5e0175846
取代。这可能就是为什么我遇到一些Table not found
错误。
答案 0 :(得分:1)
问题出在您使用的@DataJpaTest
上。
参见Documentation of @DataJpaTest
默认情况下,带有@DataJpaTest注释的测试将使用嵌入式内存数据库(替换任何显式或通常自动配置的DataSource)。 @AutoConfigureTestDatabase批注可用于覆盖这些设置。
您会在日志中找到类似的内容
EmbeddedDataSourceBeanFactoryPostProcessor : Replacing 'dataSource' DataSource bean with embedded version
要修复,请使用:
spring.test.database.replace=none
spring.jpa.properties.hibernate.default_schema=DMDEOWNER
答案 1 :(得分:0)
我最终尝试了很多事情,所以我不确定为什么它现在可以工作...
在the documentation中,据说默认情况下它将尝试找到schema.sql
来创建数据库,并尝试data.sql
来填充它。我当时使用的是自己的.sql
文件,可以同时完成这两项工作,因此我按照建议将其分开,并且开始工作!
所以现在我的application.properties如下:
# Datasource connection settings to H2 in-memory database
# To init db with h2_init_script.sql add the following to the url : INIT=CREATE SCHEMA IF NOT EXISTS DMDEOWNER\\;SET SCHEMA DMDEOWNER\\;runscript from 'classpath:h2_init_script.sql'
datasources.member-request.url=jdbc:h2:mem:db;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;IGNORECASE=TRUE;
datasources.member-request.username=sa
datasources.member-request.password=
datasources.member-request.driver-class-name=org.h2.Driver
datasources.member-request.initialize=true
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
spring.h2.console.settings.web-allow-others=true
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
由于我不再在application.properties
中创建架构,因此将其添加到schema.sql
文件中:
CREATE SCHEMA IF NOT EXISTS DMDEOWNER;
SET SCHEMA DMDEOWNER;
最后,我在Entity类的序列声明中添加了架构的名称前缀,因为我遇到了一些SEQUENCE NOT FOUND
错误:
@Entity
@Getter
@Setter
@Table(name = "T_THEME")
public class ThemeEntity {
/** Primary key of the table. */
@Id
@NotNull
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "theme_generator")
@SequenceGenerator(name = "theme_generator", sequenceName = "DMDEOWNER.SEQ_NUM_THEME", allocationSize = 1)
@Column(name = "f_num_theme")
private Long idTechnique;
//...
}
