DBunit NoSuchTableException

Question

我正在尝试将dbunit和spring-dbunit包含到我的项目中进行测试。我有两个文件夹："src/test/java/dao"one_answers"src/test/resources/dao"。

在资源dao

<?xml version='1.0' encoding='UTF-8'?>
<dataset> 
<Brands id="1" brandName="Apple" /> 
</dataset>

尝试使用大写和小写（BRANDS，BRANDS），仍然存在相同的问题。

在主java 中

public class BrandsDaoTest {
@Autowired
private BrandsDao brandsDao;
private Brand brand;
private static final int ID = 1;
private static final String BRANDNAME = "apple";
private static final String UBRANDNAME = "horizont";
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:app-context.xml","classpath:test-context.xml" })
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DbUnitTestExecutionListener.class })
@Test
@DatabaseSetup("schema.xml")
public void find(){
    Brand brand = brandsDao.find(1);
    assertNotNull(brand);
    brandsDao.delete(ID);
    assertNull(brandsDao.find(ID));
}
}

我的品牌实体：

@Entity
@Table(name = "brands")
public class Brand {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;

@Column(name="BrandName",nullable=false)
private String brandName;
@OneToMany(fetch = FetchType.LAZY)
@JoinColumn(name="BrandId",updatable=false)
private List<Device> devices;

public Brand(){
}
public Brand(int id,String brandName){
    this.id = id;
    this.brandName = brandName;
}
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}

public String getBrandName() {
    return this.brandName;
}
public void setBrandName(String brandName) {
    this.brandName = brandName;
}   

public List<Device> getDevices(){
    return this.devices;
}
public void setDevices(List<Device> devices){
    this.devices = devices;
}
 public boolean equals(Object obj) {
     boolean result = false;
       if (!(obj instanceof Brand))
            return result;
       Brand brand = (Brand)obj;
       if(this.getId() == brand.getId())
           result = true;
       return result;
 }
}

这是我的连接：

bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="org.h2.Driver"/>
    <property name="url"      value="jdbc:h2:mem:dbtest;
    MODE=MySQL;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE" />
    <property name="username" value="sa"/>
    <property name="password" value=""/>
</bean> 
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan"
        value="com.entities" />
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="connection.useUnicode">true</prop>
            <prop key="connection.characterEncoding">UTF-8</prop>
            <prop key="hibernate.hbm2ddl.auto">create-drop</prop>
        </props>
    </property>
</bean>

在使用dbunit之前，遇到了同样的问题，并且

<prop key="hibernate.hbm2ddl.auto">create-drop</prop>

现在，如果我的schema.xml文件为空并且我用"brandsDao.create（new Brand（））"方法在其中一个测试方法中添加品牌，一切都很好。但当我添加时

<Brands id="1" brandName="Apple" />

在schema.xml中，我得到了"NoSuchTableException：Brands"。

此外，在我将其插入上下文xml之前：

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory">
        <bean class="org.dbunit.ext.mysql.MySqlDataTypeFactory" />
    </property>
    <property name="caseSensitiveTableNames" value="true" />
</bean>
<bean id="dbUnitDatabaseConnection"   class="com.github.springtestdbunit.bean.
DatabaseDataSourceConnectionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="databaseConfig" ref="dbUnitDatabaseConfig"/>
</bean>

我有"在架构null中找不到表'BRANDS'"。在上尝试了不同的文章这些错误，但仍然无济于事。我想当dbunit为试图插入架构中的数据。

如有任何提示或建议，我们将不胜感激。

感谢Alan Hay的回复。我已经在我的会话中尝试了你的一组hibernate属性Factory bean

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan"
        value="com.entities" />
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">${hibernate.dialect}</prop>
            <prop key="connection.useUnicode">true</prop>
            <prop key="connection.characterEncoding">UTF-8</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.cache.use_second_level_cache">false</prop>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
        </props>
    </property>
</bean>

最有用的是

<prop key="hibernate.show_sql">true</prop>

它为我提供了创建虚拟数据库的完整跟踪。所有小写的名称，所以在更换之后

<Brands id="1" brandName="Apple" />

至

<brands id="1" brandName="Apple" /> 
<brands id="2" brandName="Apple2" /> 

它奏效了。我很确定我以前试过，也许我没有包括

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory">
        <bean class="org.dbunit.ext.mysql.MySqlDataTypeFactory" />
    </property>
    <property name="caseSensitiveTableNames" value="true" />
</bean>

当时。尽管如此，它现在运行良好。再次感谢您的提示。

现在我的hibernate属性看起来像：

 <props>
            <prop key="dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="connection.useUnicode">true</prop>
            <prop key="connection.characterEncoding">UTF-8</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <!--<prop key="hibernate.show_sql">true</prop> -->
        </props>
