java h2内存数据库错误:找不到表

Question

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.

Answer 1

经过半个小时后,我终于找到了解决方案,如果有人遇到类似的问题.

找不到表,因为在尝试创建表时开始时出错.并且错误是由于其中一个ClassifierGroupEntity字段被命名为'order',这是SQL中的保留字之一,因此Spring生成的SQL语句在语法上是不正确的.

Answer 2

在src/test/resources文件夹中的application.properties文件中具有以下属性:

spring.jpa.generate-DDL =真

spring.jpa.hibernate.ddl-AUTO =创建

这必须超过缠身,因为它没有保持创建而保持无或验证第一DDL创建之后.

Answer 3

在编写集成测试之前，我总是对 H2 数据库、Flyway、Spring Boot JPA 使用以下配置 - https://gist.github.com/vslala/d412156e5840fafa1b9f61aae5b20951

将以下配置放入您的src/test/resources/application.properties文件中。

# Datasource configuration for jdbc h2
# this is for file based persistent storage
# spring.datasource.url=jdbc:h2:file:/data/demo

# For in-memory storage
spring.datasource.url=jdbc:h2:mem:testdb;MODE=MySQL;DB_CLOSE_DELAY=-1;IGNORECASE=TRUE;
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=vslala
spring.datasource.password=simplepass
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

# This has to be over-ridden because
# it's not kept create rather kept none or validate after the first ddl creation.
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create

# This is for FlyWay configuration
spring.flyway.url=jdbc:h2:mem:testdb
spring.flyway.schemas=testdb
spring.flyway.user=vslala
spring.flyway.password=simplepass
