Spring、Hibernate、TestNG 和 h2：org.dbunit.dataset.NoSuchTableException：用户

Question

我正在尝试测试 DAO 层。该项目包括以下技术堆栈：Spring 4、Hibernate 5、MySQL、H2、Mockito、testNG、dbUnit 和其他...

这里是 pom.xml 的依赖片段：

<properties>
    <springframework.version>4.2.4.RELEASE</springframework.version>
    <hibernate.version>5.1.0.Final</hibernate.version>
    <hibernate-jpa.version>1.0.0.Final</hibernate-jpa.version>

    <mockito.version>1.10.19</mockito.version>
    <maven.test.skip>false</maven.test.skip>
    <testng.version>6.9.4</testng.version>
    <h2.version>1.3.176</h2.version>
    <dbunit.version>2.2</dbunit.version>
</properties>

测试结果returns出现如下错误堆栈：

Hibernate测试配置说明：

@Configuration
@EnableTransactionManagement
@ComponentScan({"ru.ts.js.oxaoo.srtd.dao"})
public class HibernateTestConfiguration {

    //@Autowired
    //private Environment environment;

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[]{"ru.ts.js.oxaoo.srtd.entity"});
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
    }

    @Bean
    public DataSource dataSource(){
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.h2.Driver");
        dataSource.setUrl("jdbc:h2:mem:srtd;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
        dataSource.setUsername("sa");
        dataSource.setPassword("");
        return dataSource;
    }

    @Bean
    public Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
        properties.put("hibernate.hbm2ddl.auto", "create-drop");
        return properties;
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory);
        return transactionManager;
    }
}

所有DAO测试的摘要class：

//@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {HibernateTestConfiguration.class})
public abstract class DAOTest extends AbstractTransactionalTestNGSpringContextTests {

    @Autowired
    DataSource dataSource;

    @BeforeMethod
    public void setUp() throws Exception {
        IDatabaseConnection dbConn = new DatabaseDataSourceConnection(dataSource);

        IDataSet dataSet = getDataSet();
        DatabaseOperation.CLEAN_INSERT.execute(dbConn, dataSet);
    }

    protected abstract IDataSet getDataSet() throws Exception;
}

错误发生处的相同代码行 #30:

DatabaseOperation.CLEAN_INSERT.execute(dbConn, dataSet);

执行此代码行之前调试期间的变量内容： img contents of variables。 dbConn 中的几乎所有字段都是空的。

Class 测试用户 DAO:

public class UserDAOTest extends DAOTest {
    private final static Logger log = Logger.getLogger(UserDAOTest.class.getName());

    @Autowired
    private IUserDAO userDAO;

    @Override
    protected IDataSet getDataSet() throws Exception {
        return new FlatXmlDataSet(this.getClass().getClassLoader().getResourceAsStream("user.xml"));
    }

    @Test
    public void findById(){
        if (userDAO == null) log.info("user dao is null");
        else log.info("user dao is: " + userDAO.toString());
        UserEntity ue = userDAO.findByPK("ivan@email.com");
        log.debug("Find by id: " + ue.toString());
        assertNotNull("Don't found user by id", ue);
    }
}

以及user.xml的这些内容：

<?xml version="1.0" encoding="UTF-8"?>
<dataset>
    <user email="ivan@email.com"    idPassanger="1"     password="qwerty"/>
    <user email="petr@email.com"    idPassanger="2"     password="qwerty2"/>
    <user email="dmitry@email.com"  idPassanger="3"     password="12345"/>
</dataset>

据我所知，错误是指此文件中的 "user" 标记。

这里还有用户的POJO：

@Entity
@Table(name = "user", schema = "srtd")
public class UserEntity {
    private String email;
    private String password;
    private PassangerEntity idPassanger;

    public UserEntity() {}

    public UserEntity(String email, String password, PassangerEntity idPassanger) {
        this.email = email;
        this.password = password;
        this.idPassanger = idPassanger;
    }

    @Id
    @Column(name = "email")
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Basic
    @Column(name = "password")
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @OneToOne(optional = false, cascade = CascadeType.ALL)
    @JoinColumn(name = "idPassanger", unique = true, nullable = false)
    public PassangerEntity getIdPassanger(){
        return idPassanger;
    }

    public void setIdPassanger(PassangerEntity idPassanger){
        this.idPassanger = idPassanger;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        UserEntity that = (UserEntity) o;

        if (email != null ? !email.equals(that.email) : that.email != null) return false;
        if (password != null ? !password.equals(that.password) : that.password != null) return false;

        return true;
    }

    @Override
    public int hashCode() {
        int result = email != null ? email.hashCode() : 0;
        result = 31 * result + (password != null ? password.hashCode() : 0);
        return result;
    }

    @Override
    public String toString() {
        return "UserEntity{" +
                "email='" + email + '\'' +
                ", password='" + password + '\'' +
                ", idPassanger=" + idPassanger.toString() +
                '}';
    }
}

在completer stack of errors中有如下一条日志，我觉得需要注意的是：

Caused by: org.h2.jdbc.JdbcSQLException:
Schema "SRTD" not found; SQL statement:
alter table srtd.user add constraint FKec3wluojmxshecxg06rihvlwf foreign key (idPassanger) references srtd.passanger [90079-176]

如果有必要，那我就把错误全贴出来，真相很大...

请帮我解决这个问题，我已经折腾了一整天了。

尝试从 entity 注释中删除属性 schema = "srtd"，因为 dataSource.setUrl(..) 方法已经有了它。
